114-579: Euro Truck Simulator (known as Big Rig Europe in North America) is a 2008 truck simulation game developed and published by SCS Software . The game is set in a scaled-down rendition of Europe , from England and Portugal to Poland and the Czech Republic, where players drive a variety of semi-trucks and trailers across the continent, visiting the continent's major cities, picking up and delivering cargo for various companies. More than 300,000 copies of
228-472: A dolly , which generally has to be equipped with lights and a license plate , rigid trucks can be used to pull semi-trailers. The dolly is equipped with a fifth wheel to which the trailer is coupled. Because the dolly attaches to a pintle hitch on the truck, maneuvering a trailer hooked to a dolly is different from maneuvering a fifth wheel trailer. Backing the vehicle requires the same technique as backing an ordinary truck/full trailer combination, though
342-406: A fifth wheel hitch. Box trucks have walls and a roof, making an enclosed load space. The rear has doors for unloading; a side door is sometimes fitted. Chassis cab trucks have a fully enclosed cab at the front, with bare chassis frame-rails behind, suitable for subsequent permanent attachment of a specialized payload, like a fire-truck or ambulance body. Concrete mixers have
456-402: A king pin , hooked to a horseshoe-shaped quick-release coupling device called a fifth wheel or a turntable hitch at the rear of the towing engine that allows easy hook up and release. The truck trailer cannot move by itself because it only has wheels at the rear end: it requires a forward axle , provided by the towing engine, to carry half the load weight. When braking hard at high speeds,
570-417: A misnomer (the term "eighteen-wheeler" is a nickname for a five-axle over-the-road combination). Many trailers are equipped with movable tandem axles to allow adjusting the weight distribution. To connect the second of a set of doubles to the first trailer, and to support the front half of the second trailer, a converter gear known as a "dolly" is used. This has one or two axles, a fifth-wheel coupling for
684-485: A 25 mph (40 km/h) speed governor as they are classified as low-speed vehicles. These vehicles have found uses in construction, large campuses (government, university, and industrial), agriculture, cattle ranches, amusement parks, and replacements for golf carts. Major mini-truck manufacturers and their brands include: Daihatsu Hijet , Honda Acty , Tata Ace , Mazda Scrum , Mitsubishi Minicab , Subaru Sambar , and Suzuki Carry . Light trucks are car-sized (in
798-402: A 44,000 kg (97,000 pounds) limit, an increase achieved by adding an extra axle to the tractor, usually in the form of a middle unpowered lifting axle (midlift) with a total of 14 wheels. The lift axles used on both tractors and trailers allow the trucks to remain legal when fully loaded (as weight per axle remains within the legal limits); on the other hand, these axle set(s) can be raised off
912-568: A combination to be 76 t (75 long tons; 84 short tons). At the same time the maximum allowed height would be increased by 20 cm (8 in); from current maximum of 4.2 m (13.8 ft) to 4.4 m (14.4 ft). The effect this major maximum weight increase would cause to the roads and bridges in Finland over time is strongly debated. However, longer and heavier combinations are regularly seen on public roads; special permits are issued for special cargo. The mining company Boliden AB have
1026-401: A common construction: they are made of a chassis , a cab , an area for placing cargo or equipment, axles , suspension and roadwheels , an engine and a drivetrain . Pneumatic , hydraulic , water , and electrical systems may also be present. Many also tow one or more trailers or semi-trailers. The "cab", or "cabin" is an enclosed space where the driver is seated. A " sleeper " is
1140-704: A compartment attached to or integral with the cab where the driver can rest while not driving, sometimes seen in semi-trailer trucks. There are several cab configurations: A further step from this is the side loading forklift that can be described as a specially fabricated vehicle with the same properties as a truck of this type, in addition to the ability to pick up its own load. Most small trucks such as sport utility vehicles (SUVs), vans or pickups , and even light medium-duty trucks in North America, China, and Russia use gasoline engines (petrol engines), but many diesel engined models are now being produced. Most of
1254-562: A factory to the nearest railway station. The first semi-trailer appeared in 1881, towed by a steam tractor manufactured by De Dion-Bouton . Steam-powered wagons were sold in France and the United States until the eve of World War I , and 1935 in the United Kingdom, when a change in road tax rules made them uneconomic against the new diesel lorries. In 1895, Karl Benz designed and built

#17331043226261368-493: A forward engine, one steering axle, and two drive axles . The fifth-wheel trailer coupling on most tractor trucks is movable fore and aft, to allow adjustment in the weight distribution over its rear axle(s). Ubiquitous in Europe but less common in North America since the 1990s, is the cabover engine configuration, where the driver sits next to or over the engine. With changes in the US to
1482-406: A ladder if tipped on end. The rails consist of a tall vertical section (two if boxed) and two shorter horizontal flanges. The height of the vertical section provides opposition to vertical flex when weight is applied to the top of the frame (beam resistance). Though typically flat the whole length on heavy-duty trucks, the rails may sometimes be tapered or arched for clearance around the engine or over
1596-468: A light load is being carried; an arrangement known as a TAG axle when it is the rear axle, or mid-lift when it is the center axle). Some trailers have two axles which have twin tyres on each axle; other trailers have three axles, of which one axle can be a lift axle which has super-single wheels. In the UK, two wheels bolted to the same hub are classed as a single wheel, therefore a standard six-axle articulated truck
1710-420: A manual transmission with synchromesh (synchronizers). Bigger trucks often use manual transmissions without synchronizers, saving bulk and weight, although synchromesh transmissions are used in larger trucks as well. Transmissions without synchronizers, known as "crash boxes", require double-clutching for each shift, (which can lead to repetitive motion injuries), or a technique known colloquially as "floating",
1824-545: A manual transmission, while conventional automatic or automated manual transmissions would have anything from 5 to 12 gears. Almost all heavy truck transmissions are of the "range and split" (double H shift pattern) type, where range change and so‑called half gears or splits are air operated and always preselected before the main gear selection. A truck frame consists of two parallel boxed (tubular) or C‑shaped rails, or beams, held together by crossmembers . These frames are referred to as ladder frames due to their resemblance to
1938-484: A maximum rigid length of 60 ft (18.2 m), this, combined with a shallow kingpin and fifth wheel set close to the rear of the tractor unit, can give an overall length of around 75 ft (22.75 m). In January 2012, the Department for Transport began conducting a trial of longer semi-trailers. The trial involves 900 semi-trailers of 48 ft (14.6 m) in length (i.e. 3 ft [1 m] longer than
2052-407: A method of changing gears which does not use the clutch, except for starts and stops, due to the physical effort of double-clutching, especially with non-power-assisted clutches, faster shifts, and less clutch wear. Double-clutching allows the driver to control the engine and transmission revolutions to synchronize so that a smooth shift can be made; for example, when upshifting, the accelerator pedal
2166-500: A more uncertain origin, but probably has its roots in the rail transport industry, where the word is known to have been used in 1838 to refer to a type of truck (a goods wagon as in British usage, not a bogie as in the American), specifically a large flat wagon. It might derive from the verb lurry (to carry or drag along, or to lug) which was in use as early as 1664, but that association
2280-402: A permit, and may require one or more pilot vehicles. High-productivity motor vehicle (HPMV) permits are issued for vehicles exceeding 44 tonnes, or the above dimensions. Trucks up to 62 tonnes were allowed, with an initial bridge strengthening program costing $ 12.5m. There are many types of semi-trailers in use, designed to haul a wide range of products. The cargo trailer is, by means of
2394-474: A reduction in emissions due to the one tractor unit still being used and no further highway investment being required. Furthermore, Denby Transport asserted that two Eco-Links would replace three standard semi-trailer trucks while, if limited to the current UK weight limit of 97,000 lb (44 t), it was claimed the Eco-Link would reduce carbon emissions by 16% and could still halve the number of trips needed for

#17331043226262508-401: A roof and floor, used for transporting fresh and frozen cargo such as ice cream, food, vegetables, and prescription drugs. They are mostly equipped with double-wing rear doors, but a side door is sometimes fitted. Refuse trucks have a specialized body for collecting and, often, compacting trash collected from municipal, commercial, and industrial sites. This application has the widest use of
2622-544: A rotating drum on an inclined axis, rotating in one direction to mix, and in the other to discharge the concrete down chutes. Because of the weight and power requirements of the drum body and rough construction sites, mixers have to be very heavy duty. Dual drive/Steer trucks are vehicles used to steer the rear of trailers . Dump trucks ("tippers" in the UK) transport loose material such as sand, gravel, or dirt for construction. A typical dump truck has an open-box bed, which
2736-527: A semi-trailer truck is known as an 'articulated lorry' (or colloquially as an 'artic'). The maximum permitted gross weight of a semi-trailer truck without the use of a Special Type General Order (STGO) is 44,000 kg (97,000 lb). In order for a 44,000 kg semi-trailer truck to be permitted on UK roads the tractor and semi-trailer must have three or more axles each. Lower weight semi-trailer trucks can mean some tractors and trailer having fewer axles. In practice, as with double decker buses and coaches in
2850-475: A short combination. They have one stack together with a crane on the 6×4 truck, and two additional stacks on a four axle trailer. The allowed gross weight in both countries is up to 60 t (59 long tons; 66 short tons) depending on the distance between the first and last axle. In the negotiations starting in the late 1980s preceding Sweden and Finland's entries to the European Economic Area and later
2964-463: A similar (on-going) trial in The Netherlands. Similarly, Denmark has allowed 25.25 m combinations on select routes. These vehicles will run a 60-tonne (59.1-long-ton; 66.1-short-ton) weight limit. Two types are to be used: 1) a 26-tonne truck pulling a dolly and semi-trailer, or 2) an articulated tractor unit pulling a B-double , member states gained the ability to adopt the same rules. In Italy
3078-740: A single trailer or two trailers (commonly known as "short doubles") with a maximum overall length of 19 m (62 ft) are referred to as "General access heavy vehicles" and are permitted in all areas, including metropolitan. B-doubles are limited to a maximum total weight of 62.5 tonnes and overall length of 25 m (82 ft), or 26 m (85 ft) if they are fitted with approved FUPS (Front Underrun Protection System) devices. B-doubles may only operate on designated roads, which includes most highways and some major metropolitan roads. B-doubles are very common in all parts of Australia including state capitals and on major routes they outnumber single trailer configurations. Maximum width of any vehicle
3192-704: A six-axle truck may have a maximum weight of 44 t (97,000 lb) or more. Off-road trucks include standard, extra heavy-duty highway-legal trucks, typically outfitted with off-road features such as a front driving axle and special tires for applications such as logging and construction, and purpose-built off-road vehicles unconstrained by weight limits, such as the Liebherr T 282B mining truck. Australia has complex regulations over weight and length, including axle spacing, type of axle/axle group, rear overhang, kingpin to rear of trailer, drawbar length, ground clearance, as well as height and width laws. These limits are some of

However, heavy restrictions apply to the areas where such a vehicle may travel in most states. In remote areas such as the Northern Territory great care must be taken when sharing the road with longer articulated vehicles that often travel during the daytime, especially four-trailer road trains. Articulated trucks towing
3420-455: A standing special permit for 76-tonne (75-long-ton; 84-short-ton) combinations on select routes between mines in the inland and the processing plant in Boliden , taking a 50-tonne (49-long-ton; 55-short-ton) load of ore. Volvo has a special permit for a 32 m (105 ft), steering B-trailer-trailer combination carrying two 12 m (40 ft) containers to and from Gothenburg harbour and
3534-467: A total of nine axles (including steering). In some lighter duty applications, only one of the rear axles of the truck is driven, and the trailer may have only two axles. From July 2007, the Australian Federal and State Governments allowed the introduction of B-triple trucks on a specified network of roads. B-Triples are set up differently from conventional road trains. The front of their first trailer

3648-411: A truck, of a trailer, from axle to hitch point, kingpin to rear of trailer, and turning radius are all regulated. In additions, there are special rules for carrying containers, and countries can set their own rules for local traffic. The United States Federal Bridge Law deals with the relation between the gross weight of the truck, the number of axles, the weight on and the spacing between the axles that
3762-562: A version of their Xebra electric tricycle (licensable in the U.S. as a motorcycle). Popular in Europe and Asia, many mini-trucks are factory redesigns of light automobiles, usually with monocoque bodies. Specialized designs with substantial frames such as the Italian Piaggio shown here are based upon Japanese designs (in this case by Daihatsu ) and are popular for use in "old town" sections of European cities that often have very narrow alleyways. Regardless of name, these small trucks serve
3876-566: A wide range of uses. In Japan, they are regulated under the Kei car laws, which allow vehicle owners a break in taxes for buying a smaller and less-powerful vehicle (currently, the engine is limited to 660 cc displacement). These vehicles are used as on-road utility vehicles in Japan. These Japanese-made mini-trucks that were manufactured for on-road use are competing with off-road ATVs in the United States, and import regulations require that these mini-trucks have
3990-578: Is 2.5 m (8.2 ft) and a height of 4.3 m (14 ft). In the past few years, allowance has been made by several states to allow certain designs of heavy vehicles up to 4.6 m (15 ft) high but they are also restricted to designated routes. In effect, a 4.6 meter high B-double will have to follow two sets of rules: they may access only those roads that are permitted for B-doubles and for 4.6 meter high vehicles. In Australia, both conventional prime movers and cabovers are common, however, cabovers are most often seen on B-doubles on

Truck A truck or lorry is a motor vehicle designed to transport freight , carry specialized payloads, or perform other utilitarian work. Trucks vary greatly in size, power, and configuration, but the vast majority feature body-on-frame construction, with a cabin that is independent of the payload portion of the vehicle. Smaller varieties may be mechanically similar to some automobiles . Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in
4218-511: Is considered to have twelve wheels, even though it has twenty tyres. The UK also allows semi-trailer truck which have six tyres on two axles; these are known as four-wheelers. In 2009, the operator Denby Transport designed and built a 83 ft long (25.25 m) B-Train (or B-Double) semi-trailer truck called the Denby Eco-Link to show the benefits of such a vehicle, which were a reduction in road accidents and result in fewer road deaths,
4332-427: Is hinged at the rear and lifts at the front, allowing the material in the bed to be unloaded ("dumped") on the ground behind the truck. Flatbed trucks have an entirely flat, level platform body. This allows for quick and easy loading but has no protection for the load. Hanging or removable sides are sometimes fitted, often in the form of a stakebody . Refrigerator trucks have insulated panels as walls and
4446-422: Is in neutral, it allows the engine speed to drop and synchronize engine and transmission revolutions relative to the road speed. Downshifting is performed in a similar fashion, except the engine speed is now required to increase (while the transmission is in neutral) just the right amount in order to achieve the synchronization for a smooth, non-collision gear change. "Skip changing" is also widely used; in principle,
4560-474: Is most often made as vans. Medium trucks are larger than light but smaller than heavy trucks. In the US, they are defined as weighing between 13,000 and 33,000 lb (5.9 and 15.0 t). For the UK and the EU the weight is between 3.5 and 7.5 t (7,700 and 16,500 lb). Local delivery and public service ( dump trucks , garbage trucks and fire-fighting trucks ) are normally around this size. Heavy trucks are
4674-455: Is mostly reserved for larger vehicles. In Australia and New Zealand, a pickup truck is frequently called a ute (short for "utility" vehicle), while in South Africa it is called a bakkie ( Afrikaans : "small open container"). In the United Kingdom, India, Malaysia, Singapore, Ireland, and Hong Kong lorry is used instead of truck , but only for the medium and heavy types, while truck

4788-463: Is not definitive. The expanded meaning of lorry , "self-propelled vehicle for carrying goods", has been in usage since 1911. In the United States, Canada, and the Philippines, "truck" is usually reserved for commercial vehicles larger than regular passenger cars, but includes large SUVs, pickups, and other vehicles with an open load bed. In Australia, New Zealand and South Africa, the word "truck"

The combined vehicle is 33 metres (108 ft) long, has 13 axles, and weighs a total of 104 tonnes (102 long tons; 115 short tons). Starting from 21 January 2019 the Government of Finland changed the maximum allowed length of truck from 25.25 to 34.50 meters (82.8 to 113.2 ft). New types of vehicle combinations that differ from
5016-429: Is reflected in the most popular configurations of trucks generally having dual drive axles and three axles on the trailers, with four tyres on each axle. This means that Australian single semi-trailer trucks will usually have 22 tyres, which is generally more than their counterparts in other countries. Super single tyres are sometimes used on tri-axle trailers. The suspension is designed with travel limiting, which will hold

Finally, the clutch pedal is released and the accelerator pedal pushed down to obtain the required engine speed. Although this is a relatively fast movement, perhaps a second or so while the transmission

This is a fail-safe design feature which ensures that if air pressure to either unit is lost, the vehicle will stop to a grinding halt, instead of continuing without brakes and becoming uncontrollable. The trailer controls are coupled to the tractor through two gladhand connectors , which provide air pressure, and an electrical cable, which provides power to the lights and any specialized features of

As a result, B-Triples are much more stable than road trains and handle exceptionally well. True road trains only operate in remote areas, regulated by each state or territory government. In total, the maximum length that any articulated vehicle may be (without

There are a wide variety of English-language terms for a semi-trailer truck, including: US English : British English Canadian English The main difference between tractor units in Europe and North America
5700-516: Is used almost exclusively to refer to pickups . Often produced as variations of golf cars , with internal combustion or battery electric drive , these are used typically for off-highway use on estates, golf courses, and parks. While not suitable for highway use some variations may be licensed as slow speed vehicles for operation on streets, generally as a body variation of a neighborhood electric vehicle . A few manufactures produce specialized chassis for this type of vehicle, while Zap Motors markets

In North America , the combination vehicles made up of a powered semi-tractor and one or more semitrailers are known as "semis", "semitrailers", "tractor-trailers", "big rigs", "semi-trucks", "eighteen-wheelers", or "semi-tractor-trailers". The tractor unit typically has two or three axles ; those built for hauling heavy-duty commercial-construction machinery may have as many as five, some often being lift axles . The most common tractor-cab layout has

Trucks and cars have a common ancestor: the steam-powered fardier Nicolas-Joseph Cugnot built in 1769. However, steam wagons were not common until the mid-19th century. The roads of the time, built for horse and carriages, limited these vehicles to very short hauls, usually from

The vehicle is a 30 m (98 ft) long truck trailer combination with a gross weight exceeding 90 tonnes (89 long tons; 99 short tons). It is estimated that this will give a 20% lower cost and 20–25% CO 2 emissions reduction compared to the regular 60-tonne (59-long-ton; 66-short-ton) truck combinations. As

Semi-tractors ("artics" in the UK) have a fifth wheel for towing a semi-trailer instead of a body. Semi-trailer truck A semi-trailer truck (also known by a wide variety of other terms - see below )
6384-422: The diesel engine did not appear in production trucks until Benz introduced it in 1923. The diesel engine was not common in trucks in Europe until the 1930s. In the United States, Autocar introduced diesel engines for heavy applications in the mid-1930s. Demand was high enough that Autocar launched the "DC" model (diesel conventional) in 1939. However, it took much longer for diesel engines to be broadly accepted in

Other researchers say that once faster chargers are available batteries will become competitive against diesel for all, except perhaps the heaviest, trucks. Small trucks use the same type of transmissions as almost all cars, having either an automatic transmission or

The active steer system meant that the Eco-Link had a turning circle of 41 ft (12.5 m), the same as a conventional semi-trailer truck. Although the Department for Transport advised that the Eco-Link was not permissible on public roads, Denby Transport gave

Since 1996 Sweden and Finland formally won a final exemption from the European Economic Area rules with 60 tonne and 25.25-metre (83 ft) combinations. From 2006, 25.25 m truck trailer combinations are to be allowed on restricted routes within Germany, following

On 1 December 2009 Denby Transport were preparing to drive the Eco-Link on public roads, but this was cut short because the Police pulled the semi-trailer truck over as it left the gates in order to test it for its legality "to investigate any... offenses which may be found". The Police said
7410-464: The UK is now predominantly carried out by private companies, but extremely large or heavy loads that require road closures must still be escorted by the police. In the UK, some semi-trailer trucks have eight tyres on three axles on the tractor; these are known as six-wheelers or "six leggers," with either the centre or rear axle having single wheels which normally steer as well as the front axle and can be raised when not needed (i.e. when unloaded or only
7524-468: The UK, there is no legal height limit for semi-trailer trucks; however, bridges over 16.5 ft (5.03 m) do not have the height marked on them. Semi-trailer trucks in continental Europe have a height limit of 13.1 ft (4.0 m). Vehicles heavier than 44,000 kg are permitted on UK roads but are indivisible loads, which would be classed as abnormal (or oversize). Such vehicles are required to display an STGO (Special Types General Order) plate on

Electrically powered trucks predate internal combustion ones and have been continuously available since the mid-19th-century. In the 1920s Autocar Trucks was the first of the major truck manufacturers to offer a range of electric trucks for sale. Electric trucks were successful for urban delivery roles and as specialized work vehicles like forklifts and pushback tugs . The higher energy density of liquid fuels soon led to

In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a " tractor ". The majority of trucks currently in use are powered by diesel engines , although small- to medium-size trucks with gasoline engines exist in North America . Electrically powered trucks are more popular in China and Europe than elsewhere. In
8208-506: The combination is legal in that state. Weight maximums are 20,000 lb (9,100 kg) on a single axle, 34,000 lb (15,000 kg) on a tandem, and 80,000 lb (36,000 kg) total for any vehicle or combination. There is a maximum width of 8.5 ft (2.6 m) and no maximum height. Roads other than Interstates are regulated by individual states, and laws vary widely. Maximum weight varies between 80,000 lb (36,000 kg) to 171,000 lb (78,000 kg), depending on
8322-465: The combination spreads its weight over more axles, braking distance, road wear and traffic safety is believed to be either the same or improved with the 90-tonne (89-long-ton; 99-short-ton) truck-trailer. In the same program two types of 76-tonne (75-long-ton; 84-short-ton) combinations will be tested in Dalsland and Bohuslän counties in western Sweden: an enhanced truck and trailer combination for use in
8436-457: The combination. Most states restrict operation of larger tandem trailer setups such as triple units, turnpike doubles, and Rocky Mountain doubles. Reasons for limiting the legal trailer configurations include safety concerns and the impracticality of designing and constructing roads that can accommodate the larger wheelbase of these vehicles and the larger minimum turning radii associated with them. In general, these configurations are restricted to
8550-464: The current maximum), and a further 900 semi-trailers of 51 ft (15.65 m) in length (i.e. 7 ft [2.05 m] longer). This will result in the total maximum length of the semi-trailer truck being 57 ft (17.5 m) for trailers 48 ft in length, and 61 ft (18.55 m) for trailers 51 ft long. The increase in length will not result in the 97,000 lb weight limit being exceeded and will allow some operators to approach
8664-399: The current standards may also be used on the road. The requirements for combinations also include camera systems for side visibility, an advanced emergency braking and lane detector system, electronic driving stability system and electronically controlled brakes. Maximum length of a vehicle combination 34.5 metres Maximum length of a vehicle combination 34.5 metres In the United Kingdom ,
8778-431: The decline of electric-powered trucks in favor of, first, gasoline, and then diesel and CNG-fueled engines until battery technology advanced in the 2000s when new chemistries and higher-volume production broadened the range of applicability of electric propulsion to trucks in many more roles. Today, manufacturers are electrifying all trucks ahead of national regulatory requirements, with long-range over-the-road trucks being
8892-551: The definition of a "towing implement", with Denby prepared to argue that the second trailer on the Eco-Link was one. The Department for Transport were of the opinion that this refers to recovering a vehicle after an accident or breakdown, but the regulation does not explicitly state this. During BTAC performance testing the Eco-Link was given an "excellent" rating for its performance in maneuverability, productivity, safety and emissions tests, exceeding ordinary semi-trailer trucks in many respects. Reportedly, private trials had also shown
9006-427: The dolly/semi setup is probably longer, thus requiring more space for maneuvering. The tractor/semi-trailer configuration is rarely used on timber trucks since they use the two major advantages of having the weight of the load on the drive wheels, and the loader crane used to lift the logs from the ground can be mounted on the rear of the truck behind the load, allowing a short (lightweight) crane to reach both ends of
9120-511: The eastern seaboard where the reduction in total length allows the vehicle to pull longer trailers and thus more cargo than it would otherwise. New Zealand legislation governing truck dimensions falls under the Vehicle Dimensions and Mass Rules, published by NZ Transport Agency . New rules were introduced effective 1 February 2017, which increased the maximum height, width and weight of loads and vehicles, to simplify regulations, increase
9234-483: The first internal combustion truck. Later that year some of Benz's trucks were modified to become busses by Netphener . A year later, in 1896, another internal combustion engine truck was built by Gottlieb Daimler , the Daimler Motor Lastwagen . Other companies, such as Peugeot , Renault and Büssing , also built their own versions. The first truck in the United States was built by Autocar in 1899 and
9348-516: The forest and a b-double for plain highway transportation to the mill in Skoghall . In 2012, the Northland Mining company received permission for 90-tonne (89-long-ton; 99-short-ton) combinations with normal axle load (an extra dolly) for use on the 150 km (93 mi) Kaunisvaara - Svappavaara route, carrying iron ore. As of 2015 , the longest and heaviest truck in everyday use in Finland
9462-473: The front of the tractor unit and, under certain circumstances, are required to travel by an authorized route and have an escort. Most UK trailers are 45 ft (13.7 m) long and, dependent on the position of the fifth wheel and kingpin , a coupled tractor unit and trailer will have a combined length of between 50 and 55 ft (15.25 and 16.75 m). Although the Construction and Use Regulations allow
9576-833: The game have been sold in Europe. It is the first instalment in the Truck Simulator series of games. Euro Truck Simulator features a realistic experience for driving trucks around Europe. The player has to deliver goods around Europe while obeying street signs, highway rules and managing their fuel levels. Euro Truck Simulator has different truck models from different real companies. Each truck has its own engine power, tires and size that affect driving. The game doesn't feature an ending and allows players to continue after having completed all objectives. The game features four European truck models, available in three classes each, with working instruments such as flashing indicators, temperature and low fuel warning lights, wipers, and gauges. Since
9690-410: The game lacks official license from truck manufacturers, the trucks included, despite closely resembling real-life truck models, are given generic names, namely Majestic ( Mercedes-Benz Actros ), Runner ( Renault Magnum ), Swift ( Scania R-series ) and Valiant ( Volvo FH16 ). The game received mostly positive reviews from critics at the time of its release. Reviewers highlighted the game's good graphics,
9804-432: The game world and a "satisfying driving experience". They also mentioned the long driving times and repetitive gameplay as uninteresting for those not fans of transportation simulators. User scores on Metacritic , Steam and GameSpot indicate more favourable opinions from customers than initial reviews suggested. A sequel, Euro Truck Simulator 2 , was released in 2012. This vehicle simulation game -related article
9918-443: The heavier trucks use four-stroke diesel engines with a turbocharger and intercooler . Huge off-highway trucks use locomotive-type engines such as a V12 Detroit Diesel two stroke engine. A large proportion of refuse trucks in the United States employ CNG (compressed natural gas) engines for their low fuel cost and reduced carbon emissions. A significant proportion of North American manufactured trucks use an engine built by
10032-440: The highest in the world, a B-double can weigh 62.5 t (61.5 long tons; 68.9 short tons) and be 25 m (82 ft) long, and road trains used in the outback can weigh 172 t (169.3 long tons; 189.6 short tons) and be 53.5 m (176 ft) long. The European Union also has complex regulations. The number and spacing of axles, steering, single or dual tires, and suspension type all affect maximum weights. Length of
10146-407: The largest on-road trucks, Class 8 . These include vocational applications such as heavy dump trucks, concrete pump trucks, and refuse hauling, as well as ubiquitous long-haul 4x2 and 6×4 tractor units . Road damage and wear increase very rapidly with the axle weight. The number of steering axles and the suspension type also influence the amount of the road wear. In many countries with good roads
10260-457: The last remaining major independent engine manufacturer ( Cummins ) but most global OEMs such as Volvo Trucks and Daimler AG promote their own "captive" engines. In the European Union, all new truck engines must comply with Euro VI emission regulations, and Euro 7 from the late 2020s has stricter exhaust limits and also limits air pollution from brakes and tires . As of 2019 several alternative technologies are competing to displace
10374-418: The legal maximum total length. Furthermore, it offers greater maneuverability in confined areas, a more balanced weight-distribution, and better overall view for the driver. The major disadvantage is that for repairs on COE trucks, the entire cab has to hinge forward to allow maintenance access. In Europe, usually only the driven tractor axle has dual wheels, while single wheels are used for every other axle on
10488-909: The maximum length of the combined vehicle, the cabover was largely phased out of North American over-the-road (long-haul) service by 2007. Cabovers were difficult to service; for a long time, the cab could not be lifted on its hinges to a full 90-degree forward tilt, severely limiting access to the front of the engine. As of 25 May 2016 , a truck could cost US$ 100,000 , while the diesel fuel cost could be $ 70,000 per year. Trucks average from 4 to 8 miles per US gallon (59 to 29 L/100 km), with fuel economy standards requiring better than 7 miles per US gallon (34 L/100 km) efficiency by 2014. Power requirements in standard conditions are 170 hp (130 kW) at 55 mph (89 km/h) or 280 hp (210 kW) at 70 mph (113 km/h), and somewhat different power usage in other conditions. The cargo trailer usually has tandem axles at
10602-444: The maximum length was unlimited; the only limitations were on axle load. What stopped Sweden from adopting the same rules as the rest of Europe, when securing road safety, was the national importance of a competitive forestry industry. Finland, with the same road safety issues and equally important forestry industry, followed suit. The change made trucks able to carry three stacks of cut-to-length logs instead of two, as it would be in
10716-444: The maximum permitted weight (unless exceptional transport is authorized) is 44 tonnes for any kind of combination with five axles or more. Czech Republic has allowed 25.25 m combinations with a permission for a selected route. Denmark and Norway allow 25.25 m (83 ft) trucks (Denmark from 2008, and Norway from 2008 on selected routes). In Sweden , the allowed length has been 24 m (79 ft) since 1967. Before that,
10830-647: The most challenging. Truck is used in American English ; the British English equivalent is lorry. The first known usage of "truck" was in 1611 when it referred to the small strong wheels on ships' cannon carriages, and comes from "Trokhos" (Greek) = "wheel". In its extended usage, it came to refer to carts for carrying heavy loads, a meaning known since 1771. Its expanded application to "motor-powered load carrier" has been in usage since 1930, shortened from "motor truck", which dates back to 1901. "Lorry" has
10944-424: The operation is the same as double-clutching, but it requires neutral be held slightly longer than a single-gear change. Common North American setups include 9, 10, 13, 15, and 18 speeds. Automatic and automated manual transmissions for heavy trucks are becoming more and more common, due to advances both in transmission and engine power. In Europe, 8, 10, 12, and 16 gears are common on larger trucks with
11058-584: The rear trailer, and a tongue with a ring-hitch coupling for the forward trailer. Individual states may further allow longer vehicles, known as "longer combination vehicles" (or LCVs ), and may allow them to operate on roads other than Interstates. Long combination vehicle types include: The US federal government, which only regulates the Interstate Highway System , does not set maximum length requirements (except on auto and boat transporters), only minimums. Tractors can pull two or three trailers if
11172-435: The rear, each of which has dual wheels , or eight tires on the trailer, four per axle. In the US it is common to refer to the number of wheel hubs, rather than the number of tires; an axle can have either single or dual tires with no legal difference. The combination of eight tires on the trailer and ten tires on the tractor is what led to the moniker eighteen wheeler , although this term is considered by some truckers to be
11286-422: The rim off the road for one blown or deflated tyre for each side of the trailer, so a trailer can be driven at reduced speed to a safe place for repair. Super singles are also often used on the steer axle in Australia to allow greater loading over the steer axle. The increase in loading of steer tyres requires a permit. Long haul transport usually operates as B-doubles with two trailers (each with three axles), for
11400-525: The road compared to the standard six-axle 97,000 lb (44 t) semi-trailer truck. The vehicle was built after Denby Transport believed they had found a legal-loophole in the present UK law to allow the Eco-Link to be used on the public roads. The relevant legislation concerned the 1986 Road Vehicles Construction and Use Regulations. The 1986 regulations state that "certain vehicles" may be permitted to draw more than one trailer and can be up to 85 ft (25.9 m). The point of law reportedly hinged on
11514-437: The roadway for increased maneuverability or for reduced fuel consumption and tire wear when carrying lighter loads. Although lift axles usually operate automatically, they can be lowered manually even while carrying light loads, in order to remain within legal (safe) limits when, for example, navigating back-road bridges with severely restricted axle loads. For greater detail, see the United Kingdom section , below. When using
11628-428: The same amount of cargo carried in conventional semi-trailer trucks. This is based on the fact that for light but bulky goods such as toilet paper, plastic bottles, cereals and aluminum cans, conventional semi-trailer trucks run out of cargo space before they reach the weight limit. At 97,000 lb (44 t), as opposed to 132,000 lb usually associated with B-Trains, the Eco-Link also exerts less weight per axle on
11742-446: The semi-trailers to 16.5 m (54 ft) and 18.75 m are met with trucks carrying a standardized 7.82 m (26 ft) body with one additional 7.82 m body on tow as a trailer. 25.25-metre (83 ft) truck combinations were developed under the branding of EcoCombi which influenced the name of EuroCombi for an ongoing standardization effort where such truck combinations shall be legal to operate in all jurisdictions of
11856-460: The tractor and the trailer. The most common combination used in Europe is a semi tractor with two axles and a cargo trailer with three axles, one of which is sometimes a lift axle , giving 5 axles and 12 wheels in total. This format is now common across Europe as it is able to meet the EU maximum weight limit of 40,000 kg (88,000 pounds) without overloading any axle. Individual countries have raised their own weight limit. The U.K., for example, has
11970-434: The tractor and trailer are separated without first uncoupling the air lines. These connectors are similar in design to the ones used for a similar purpose between railroad cars . Two air lines typically connect to the trailer unit. An emergency or main air supply line pressurizes the trailer's air tank and disengages the emergency brake, and a second service line controls the brake application during normal operation. In
12084-403: The tractor unit. The most common failure is brake fade , usually caused when the drums or discs and the linings of the brakes overheat from excessive use. The parking brake of the tractor unit and the emergency brake of the trailer are spring brakes that require air pressure in order to be released. They are applied when air pressure is released from the system, and disengaged when air pressure
12198-433: The trailer. Glad-hand connectors (also known as palm couplings ) are air hose connectors, each of which has a flat engaging face and retaining tabs. The faces are placed together, and the units are rotated so that the tabs engage each other to hold the connectors together. This arrangement provides a secure connection but allows the couplers to break away without damaging the equipment if they are pulled, as may happen when
12312-575: The truck can have on the Interstate highway system. Each State determines the maximum permissible vehicle , combination , and axle weight on state and local roads. Uniquely, the State of Michigan has a gross vehicle weight limit of 164,000 lb (74 t), which is twice the U.S. federal limit. A measure to change the law was defeated in the Michigan Senate in 2019. Almost all trucks share
12426-405: The use of diesel engines in heavy trucks. CNG engines are widely used in the US refuse industry and in concrete mixers, among other short-range vocations, but range limitations have prevented their broader uptake in freight hauling applications. Heavy electric trucks and hydrogen-powered trucks are new to the market in 2021, but major freight haulers are interested. Although cars will be first
12540-481: The vehicle has a tendency to fold at the pivot point between the towing vehicle and the trailer. Such a truck accident is called a "trailer swing", although it is also commonly described as a "jackknife." Jackknifing is a condition where the tractive unit swings round against the trailer, and not vice versa. Semi trucks use air pressure, rather than hydraulic fluid, to actuate the brake . The use of air hoses allows for ease of coupling and uncoupling of trailers from
12654-491: The vehicle was unlawful due to its length and Denby Transport was served with a notice by the Vehicle and Operator Services Agency (VOSA) inspector to remove the vehicle from the road for inspection. Having returned to the yard, Denby Transport was formally notified by Police and VOSA that the semi-trailer truck could not be used. Neither the Eco-Link, nor any other B-Train, have since been permitted on UK roads. However, this prompted
12768-453: The vehicle without uncoupling. Also, construction trucks are more often seen in a rigid + midaxle trailer configuration instead of the tractor/semi-trailer setup. The maximum overall length in the EU and EEA member states was 18.75 m (61.5 ft) with a maximum weight of 40 or 44 tonnes (39.4 or 43.3 long tons; 44.1 or 48.5 short tons) if carrying an ISO container . However, rules limiting
12882-455: The weight limit which may not have been previously possible due to the previous length of trailers. The trial will run for a maximum of 10 years. Providing certain requirements are fulfilled, a Special Types General Order (STGO) allows for vehicles of any size or weight to travel on UK roads. However, in practice, any such vehicle has to travel by a route authorized by the Department of Transport and move under escort. The escort of abnormal loads in
12996-631: Was available with 5 or 8 horsepower (4 or 6 kW) engines. Another early American truck was built by George Eldridge of Des Moines, Iowa, in 1903. It was powered by an engine with two opposed cylinders, and had a chain drive A 1903 Eldridge truck is displayed at the Iowa 80 Trucking Museum, Walcott, Iowa. Trucks of the era mostly used two-cylinder engines and had a carrying capacity of 1.5 to 2 t (3,300 to 4,400 lb). After World War I, several advances were made: electric starters , and 4, 6, and 8 cylinder engines. Although it had been invented in 1897,
