Climbing Hold
A climbing hold is a shaped grip that is usually attached to a climbing wall so climbers can grab or step on it. On most walls, climbing holds are arranged in paths, called routes, by specially trained route setters. Climbing holds come in a large array of sizes and shapes to provide different levels of challenge to a climber. Climbing holds are either bolted to a wall via hex-head bolts and existing t-nuts or they are screwed on with several small screws. In extreme cases, concrete anchors may be used (if putting holds on the underside of a bridge, for example). Early materials Rock Early climbing holds were made from real rocks that were cast into concrete blocks; later they were rocks with holes drilled in them so they could be attached to a wall. While the feel of these holds is realistic, rock holds are heavy and can polish with heavy use. Rock holds are also difficult to manufacture. Wood Wood was another early hold-making material, mainly because it was inexpens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Action Directe (climb)
''Action Directe'' () is a short sport climb at the limestone Waldkopf crag in Frankenjura, Germany. When it was first climbed by German climber Wolfgang Güllich in 1991, it became the first climb in the world to have a consensus grade. It is considered an important and historic route in rock climbing history, and one of the most attempted climbs at its grade, where it is considered the "benchmark" for 9a. The training techniques Güllich used to prepare for the unique physical demands of ''Action Directe'' also revolutionized climbing and what could be achieved. History A close friend of Güllich, German climber Milan Sykora introduced him to the route that he had been working on at a large limestone prow at the Waldkopf crag, which was akin to an enormous boulder. Sykora was one of the leading German climbers at the time and had created several new routes UIAA grade X. In the 1980s, Sykora had bolted a line coming from the right and had managed to climb the individual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fiberglass
Fiberglass (American English) or fibreglass ( Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non- magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFR ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyurethane
Polyurethane (; often abbreviated PUR and PU) refers to a class of polymers composed of organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials. This chemical variety produces polyurethanes with different chemical structures leading to many different applications. These include rigid and flexible foams, varnishes and coatings, adhesives, electrical potting compounds, and fibers such as spandex and PUL. Foams are the largest application accounting for 67% of all polyurethane produced in 2016. A polyurethane is typically produced by reacting an isocyanate with a polyol. Since a polyurethane contains two types of monomers, which polymerize one after the other, they are classed as alternating copolymers. Both the isocyanates and polyols used to make a polyurethane contain two or more functional groups per molecule. Global production in 2019 wa ...

Resin
In polymer chemistry and materials science, resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are usually mixtures of organic compounds. This article focuses on naturally occurring resins. Plants secrete resins for their protective benefits in response to injury. The resin protects the plant from insects and pathogens. Resins confound a wide range of herbivores, insects, and pathogens, while the volatile phenolic compounds may attract benefactors such as parasitoids or predators of the herbivores that attack the plant. Composition Most plant resins are composed of terpenes. Specific components are alpha-pinene, beta-pinene, delta-3 carene, and sabinene, the monocyclic terpenes limonene and terpinolene, and smaller amounts of the tricyclic sesquiterpenes, longifolene, caryophyllene, and delta-cadinene. Some resins also contain a high proportion of resin acids. Rosins on the other hand are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyester
Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in plants and insects, as well as synthetics such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind and environmental resistance compared to plant-derived fibers. They are less fire-resistant and can melt when ignited. Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are used for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campus Board
A campus board is a training tool that has been widely adopted by sport climbers to improve their plyometric performance; it was invented in 1988 by German climber Wolfgang Güllich to help him climb the world's hardest-ever route, '' Action Directe'', and has since become a standard training tool for climbers. Description Typically, a user ascends or descends the campus board using only their hands, and often leaping from hold to hold (i.e both hands are off the board while transitioning between holds). Campus boards can take a variety of different forms and may incorporate a variety of materials. The earliest campus boards, and still used today, were made of horizontal thin slats or rails of wood attached to an inclined board in a ladderlike configuration. Later versions have utilized bolt-on climbing holds or sections of a pipe. A campus board is generally set at an overhanging angle of inclination. One consideration for selecting the angle of inclination is the avoidance o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climbing Wall
A climbing wall is an artificially constructed wall with grips for hands and feet, usually used for indoor climbing, but sometimes located outdoors. Some are brick or wooden constructions, but on most modern walls, the material most often used is a thick multiplex board with holes drilled into it. Recently, manufactured steel and aluminum have also been used. The wall may have places to attach belay ropes, but may also be used to practice lead climbing or bouldering. Each hole contains a specially formed t-nut to allow modular climbing holds to be screwed onto the wall. With manufactured steel or aluminum walls, an engineered industrial fastener is used to secure climbing holds. The face of the multiplex board climbing surface is covered with textured products including concrete and paint or polyurethane loaded with sand. In addition to the textured surface and hand holds, the wall may contain surface structures such as indentions (incuts) and protrusions (bulges), or take ...

Wolfgang Güllich
Wolfgang Güllich (24 October 1960 – 31 August 1992) was a German rock climber, who is considered one of the greatest and most influential climbers in the history of the sport. Güllich dominated sport climbing for most of the decade after his 1984 ascent of ''Kanal im Rücken'', the world's first-ever redpoint of an route. He continued to set more "new hardest grade" breakthroughs than any other climber in sport climbing history, with ''Punks in the Gym'' in 1985, the world's first-ever , ''Wallstreet'' in 1987, the world's first-ever , and with '' Action Directe'' in 1991, the world's first-ever . Güllich was the first-ever person to free solo at grade with his 1986 ascent of ''Weed Killer'', and in that same year did his iconic free solo of '' Separate Reality''. He made first ascents of important new big wall climbing routes on the Trango Towers and the Paine Towers. With long-time climbing partner Kurt Albert, he revolutionized the training techniques for spo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
