17-494: Phoenix is Tatra's main general purpose vehicle intended for civilian customers, while model T817 is intended primarily for military users. For the Tatra 158 Phoenix model line, Tatra does not use air-cooled engines of its own design, but uses Paccar MX engines, according to the emissions standards of Euro III, Euro V, and since 2015 with Euro VI. Standard is the 16-speed gearbox ZF , manual or automatic. The auxiliary transmission

34-513: A demolition crane by adding a demolition ball , or to an earthmover by adding a clamshell bucket or a dragline and scoop, although design details can limit their effectiveness. Before 1870 cranes were fixed to a position, except for some mounted on flatcars , railroad cranes , which provided some restricted movement. Appleby Brothers demonstrated steam-powered cranes at Paris in 1867 and Vienna in 1873. In 1922, Henry Coles, manager of Appleby Corp., began producing truck-mounted cranes under

51-465: A cabin that allows the simple addition of armor components in line with the STANAG 4569 standard. Cab tightness allowed for the use of overpressure filtering. While originally intended for military operators, the truck has been offered to civilian customers since 2010, particularly for specialist purposes such as firefighting. The second generation T817 was introduced in 2016. Its cabin was modernized and

68-474: A completely reconstructed cabin floor. Tatra 815-7 The Tatra 815-7 (also known as Tatra 817 , T817 or Tatra Force ) is a heavy army logistics vehicle made by the Czech company Tatra produced since 2007. T817 is primarily intended for military operators and for specialist roles in civilian sector (with Tatra 158 Phoenix being the company's primary general-purpose truck for civilian sector). The truck

85-512: A four-door long cab version was introduced. The chassis was modernized and unified with the Tatra 158 Phoenix . Apart from a standard cab, the truck was now offered with a high level of protection of armored cabs produced by sister company Tatra Defence Vehicles. In May 2023, at the PYROS expo, the third generation T817 was introduced when two fire trucks were presented to the public. This new version offers

102-563: A line of water-cooled Cummins engines. At the time of introduction, a hydrogen powered version was under development. Tatra 817 standard trucks serve in the Army of the Czech Republic and the Slovak Armed Forces , while 817 chassis with specialist superstructures (e.g., artillery cannon, rocket launcher, armored recovery vehicle, etc.) serve also in many other countries. It is also used in

119-431: A modernized cabin coupled with a modified position of the engine. The new four-door cabin offers enough space for up to eight crewmen in three rows. Tatra air-cooled V8 engines were also modernized, offering up to 340kW of power output. With the third generation, Tatra re-introduced its previously discontinued air-cooled V12 engine, offering up to 440 kW of power output. The third generation continues to be available with

136-495: A site and use with different types of load and cargo with little or no setup or assembly. Mobile cranes generally operate a boom, from the end of which a hook is suspended by wire rope and sheaves . The wire ropes are operated by whatever prime movers the designers have available, operating through a variety of transmissions . Steam engines , electric motors , and internal combustion engines (IC) have all been used. Older cranes' transmissions tended to be clutches . This

153-416: Is made primarily with axle variations of 4×4 , 6×6 , 8×8 and 10×10. Other chassis variants up to 16x16 are also available. In 2004, Tatra introduced a prototype of the new 817 line of trucks after presenting a 4x4 NATO C-130 Hercules transportable military truck. The prototype was based on Tatra's traditional backbone chassis, with a water cooled Cummins engine and a ZF transmission . Even though

170-871: Is of Tatra's own construction. The vehicle is built on the Tatra-concept chassis. Angle of approach is at 31°, this is one of the best values of the approach angle among off-road all-wheel drive trucks. The Tatra Phoenix won second place in the European Truck of the Year 2012 competition. At Silva Regina 2012 exhibit in Brno has been awarded by the “Extraordinary Award of the CEO and Jury". The first Tatra Phoenix Euro VI vehicles appeared in operation in early 2015. They have new facelifted cabins designed by DAF (again in Day or Sleeper Cab versions) and

187-631: The 10-ton fully telescopic hydraulic boom in 1966, followed in 1968 by the 30-ton "Husky" military versions with four-wheel drive . In 1972, Steels was forced to merge with the Acrow Group, losing some of their most valuable employees, including Don Hassel and Johnny Johnson who started a new manufacturing processes plant. With backing from the British Crane Hire Corporation they acquired a small factory unit and ordered every single element of their product from subcontracted suppliers. In 1976,

204-540: The T817 chassis to be used as the basis of other specialist vehicles made in a number of countries. The following armoured personnel carriers and mine-resistant ambush protected vehicles use T817 chassis: Mobile crane A mobile crane is a cable-controlled crane mounted on crawlers or rubber-tired carriers or a hydraulic-powered crane with a telescoping boom mounted on truck -type carriers or as self-propelled models. They are designed to easily transport to

221-483: The civilian sector, especially in applications that particularly benefit from the truck's lower center of gravity, such as mobile cranes and fire trucks . The T817 uses a traditional Tatra backbone tube chassis instead of the more typical truck ladder frame . The chassis is designed primarily for off-road applications, which gives it a comparative advantage over trucks primarily intended for roads that were modified for offroad use. As such, Tatra Czech manufactured

238-523: The name Petrol Electric Lorry Crane. In 1939 the Coles were acquired by Steel and Co. Ltd. of Sunderland. Hiab invented the world's first hydraulic truck mounted crane in 1947. The name, Hiab, comes from the commonly used abbreviation of Hydrauliska Industri AB, a company founded in Hudiksvall, Sweden in 1944 by Eric Sundin, a ski manufacturer who saw a way to utilize a truck's engine to power loader cranes through

255-476: The truck was being developed as an entirely new line, the company decided to formally introduce it to the market under the 815-7 designation as a new version of the Tatra 815 , in order to undergo a simplified homologation process. The Tatra 817 entered serial production in 2007. This serial version offered a large extent of modularity for chassis components, engines (air-cooled Tatra or water-cooled Cummins), transmissions (manual, semi-automatic, automatic), and

272-468: The use of hydraulics. Major crane development events include adoption of the internal combustion engine in 1922 and the invention of telescopic jibs. Before 1960, cranes carried additional booms with them to increase height, which increased operating costs. In 1959 crane expert R.H.Neal, hydraulics specialist F.Taylor, and design director Bob Lester, integrated all three and modernized cranes. The Coles Hydra Speedcrane appeared in 1962, further modified with

289-430: Was later modified when using IC engines to match the steam engines' "max torque at zero speed" characteristic by the addition of a hydrokinetic element, culminating in controlled torque converters . The operational advantages of this arrangement can now be achieved by electronic control of hydrostatic drives, which for size and other considerations is becoming standard. Some examples of this type of crane can be converted to
