A coiling or coil is a curve , helix , or spiral used for storing rope or cable in compact and reliable yet easily attainable form. They are often discussed with knots .
23-430: Rope are often coiled and hung up in lofts for storage. They are also hung over stakes in farm wagons and on hooks in moving vans, fire apparatus and linesmen's repair trucks. For such active storage coils must be well made. The mountaineer's coil (also alpine coil , climber's coil , lap coil , or standing coil ) is a traditional method used by climbers to store and transport a climbing rope . This older style coil
46-412: A cable in the same direction coil after coil, has the similar result to coiling cable on a spool . If the cable comes off the spool the same way it goes on, the internal 'lay' is preserved, and the cable isn't damaged or twisted internally. If a cable is straight coiled and then pulled from the coil, it has the effect as coiling cable on a spool and then pulling the cable off the top of the spool, imparting
69-411: A cheaper alternative to other types of drums, used extensively in the building industry and by commercial electricians. Often made of birch or poplar ply, they are both strong and light-weight. In normal situations, plywood reels are used only once and then destroyed. Often manufactured from recycled plastic , these reels are environmentally friendly and used for lighter weight cables. Nowadays
92-414: A knot will appear with every other loop. Connecting the ends on the outside of the loops, or tying them in that position, ensures that the ends don't pass through the loops in storage so there are no knots when the cable is laid out. There are a number of informal terms in common circulation including "over/under wrapping", "countercoiling", and "flip-coiling". Straight coiling, or the practice of coiling
115-439: A twist in the cable with every coil that is removed. To make it lie flat, the twist will need to be removed. The advantages of straight coiling cable are that it will not produce knots when uncoiling and is easily taught and therefore can be accomplished easily by assistants. Climbing Climbing is the activity of using one's hands, feet, or other parts of the body to ascend a steep topographical object that can range from
138-1081: Is a traveling film festival that exclusively screens climbing and adventure films, and includes the Reel Rock climbing film series. Cable reel A cable reel is a round, drum-shaped object such as a spool used to carry various types of electrical wires . Cable reels, which can also be termed as drums, have been used for many years to transport electric cables, fiber optic cables and wire products. Cable reels usually come in four different types, each with their own uses: wood , plywood , plastic and steel . Wooden drums come in three different varieties: steel-tyred for multiple use, export for sending abroad, and one-way drums for single trip use. Wooden drums can carry heavy loads and are constructed in resinous wood . Discarded wooden reels can often be obtained cheaply and are, owing to their shape, commonly used as furniture (usually coffee tables ) for college students and others seeking inexpensive furnishings. Plywood reels are used for transporting lighter loads and are
161-411: Is noted as being more prone to twists and tangles than the butterfly coil , and care must be taken upon uncoiling to avoid these problems. Begin by taking hold of the rope in one hand with its end facing you. Coil the rope in arm's length sections with your free hand (extending it away from the other as far as it will reach to ensure each segment is of equal length as it is gathered). Alternate tucking
184-524: Is recognized by the IOC and GAISF and is a member of the International World Games Association ( IWGA ). Competition climbing has three parts: Competition ice climbing is a regulated sport of 'competitive ice climbing' that originated in the early 2000s, and which is done on outdoor or indoor climbing on artificial ice climbing walls that consist of ice and dry surfaces. The UIAA is
207-412: The twisted pairs within. It allows the cable to lie flat when uncoiled, and makes for easier and faster work. The "over/under" name refers to the practice of twisting the cable in one direction to make the first coil, and un-twisting it to make the next, and repeating this until all the cable is neatly coiled. Care needs to be taken to keep each end on its proper side of the roll when uncoiling otherwise
230-501: The 2020 Summer Olympics ) in that format that included competition lead climbing , competition bouldering , and competition speed climbing disciplines; competition ice climbing is not yet an Olympic sport. Rock climbing can trace its origins to the late 19th-century , and has since developed into several main sub-disciplines. Single-pitch and multi-pitch (and big wall) climbing, can be performed in varying styles (including aid, sport, traditional, free solo, and top-roping), while
253-439: The bight then grasp the standing end and pull it away from the bight until it is cinched tight around the working end. For added security, ensure both ends are sufficiently long to tie them into a reef knot . The butterfly coil (also known as a backpacker's coil ) is a method used by climbers for storing and transporting a climbing rope . Slinging the coiled rope over the shoulders and tying it in place for carrying earns

#1732847539160276-402: The coil by wrapping both strands twice round both lobes approximately 1–1.5' down, then pass a short bight above the wraps and through the coil. Pass both free ends over the top of the coil and through the bight to cinch it tight. Attach the rope for transport by placing the coil atop one's back, with one free end passing over each shoulder. Pass the ends back under the armpits, cross them over
299-402: The coil, then bring them forward again, securing in front with a square knot . An alternate method draws the doubled rope over the shoulders instead of in front of the climber. Over/under cable coiling refers to a method of storing cables that preserves the capacitance and common-mode rejection ratio built in by the manufacturer with a twist in the cable, and the shielding that encases
322-451: The development of competition climbing , increased the popularity of rock climbing as a sport, and led to the emergence of professional rock climbers, such as Wolfgang Güllich , Alexander Huber , Chris Sharma , Adam Ondra , Lynn Hill , Catherine Destivelle , and Janja Garnbret . Climbing became an Olympic sport for the first time in the 2021 Olympic Games in Tokyo (see Sport climbing at
345-574: The governing body for competition ice climbing worldwide and their events include a lead ice climbing discipline and a speed ice climbing discipline. Competition ice climbing is not as yet an Olympic Sport. Climbing has been the subject of both narrative and documentary films. Notable climbing films include Touching the Void (2003), Everest (2015), Meru (2015), The Dawn Wall (2015), Free Solo (2018), 14 Peaks: Nothing Is Impossible (2021), and The Alpinist (2021).

368-467: The neck), two knees, passive side palm and elbow, or two fingers of the passive hand. The following is for the extra long climbing rope. Start with both rope ends in one hand. Pull 1.5–2 arm lengths of the pair through and let their ends hang free. Begin coiling the balance of both strands one arm length at a time, alternating the gathers in the opposite hand into two separate "lobes" (or wings) draping on either side. With 1.5–2 arm lengths remaining secure
391-443: The new gather in front and behind the previous coil to avoid putting a half-turn in the rope with each coil. When the last segment is reached form a short bight atop the gathered rope with its standing end . Grasp the working end and pass it over the bight and back through the center of the coiled rope in a round turn several times, making each new wrap closer to the bight until only a short tail remains. Pass this tail through
414-444: The popularity of the sport in the natural environment. Early pioneers included Walter Bonatti , Riccardo Cassin , Hermann Buhl , and Gaston Rébuffat , who were followed by and Reinhold Messner and Doug Scott , and later by Mick Fowler and Marko Prezelj , and Ueli Steck . Since the 1980s, the development of the safer format of bolted sport climbing , the wider availability of artificial climbing walls and climbing gyms, and
437-419: The standalone discipline of bouldering (or boulder climbing) is by definition performed in a free solo format. Competition climbing (sometimes confusingly called "sport climbing"), is a regulated sport of 'competitive rock climbing' that originated in the 1980s, and which is done as indoor climbing on artificial climbing walls . The IFSC is the governing body for competition rock-climbing worldwide and
460-507: The steel drums have replaced the orthodox wooden drums in the cable and wire industry, but mainly in the offshore industry. Steel drums are normally welded as a fixed drum, but collapsible steel drums also exist. The steel reels/drums are manufactured in an eco-friendly manner and are more durable than wooden drums, but at a significantly higher cost. These steel reels are not as easily stolen. The offshore industry today prefers steel reels/drums instead of wooden, plywood or plastic reels/drums, but
483-406: The technique its alternative name. Unlike the alpine coil it cannot be attached to a harness for climbing, and thus is useful only for transporting a rope to and from where it must be used. The method is also useful for much smaller items such as for keeping earphone cables from tangling. Depending on the thickness and length, one can use palms of hands stretched out to the sides (crossing over

#1732847539160506-496: The traditional land based industry prefers wooden drums due to their lower cost. The steel reels can be loaded with different ranges of cables and wires from the most heavy cables to the lightest wires. Certain cable reels are built with a retracting mechanism built in. In most cases, the cables on these reels carry mains electricity , though a similar mechanism is used for air hoses . Retractable cable reels are particularly useful for environments where access to electricity or air
529-722: The world's tallest mountains (e.g. the eight thousanders ) to small boulders . Climbing is done for locomotion, sporting recreation, for competition, and is also done in trades that rely on ascension, such as construction and military operations. Climbing is done indoors and outdoors, on natural surfaces (e.g. rock climbing and ice climbing ), and on artificial surfaces (e.g. climbing walls and climbing gyms ) The sport of climbing evolved by climbers making first ascents of new types of climbing routes , using new climbing techniques , at ever-increasing grades of difficulty , with ever-improving pieces of climbing equipment . Guides and guidebooks were an important element in developing
