Removable Bolt
A removable bolt (or RB), in climbing, is a spring loaded metal camming device used to anchor a person or a load to a rock or cement wall temporarily. Removable Bolts negate the need to install permanent protection bolts to the wall, which can be costly and cause cosmetic damage. RBs are designed for use in bolting new sport climbing routes A climbing route () is a path by which a Climbing, climber reaches the top of a mountain, a rock face or an ice-covered obstacle. The details of a climbing route are recorded in a climbing guidebook and/or in an online climbing-route database. De ..., setting temporary anchors on traditional routes, and on back-country expeditions where abandoning gear or placing permanent gear is not optimal. RBs are particularly popular when placing permanent bolts on steep walls with limited features, where other means of temporary protection, such as hooks, traditional camming devices, or slings, are not an option. By drilling a hole and inserting an RB ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 the popularity of the sport in the natural environment. Early pioneers included Walter Bonatti, Riccardo Cassin, Hermann Buhl, and Gaston Rébuffat, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spring-loaded Camming Device
A spring-loaded camming device (also SLCD, cam or friend) is a piece of rock climbing or mountaineering protection equipment. It consists of two, three, or four cams mounted on a common axle or two adjacent axles, so that pulling on the axle forces the cams to spread further apart. It is then attached to a sling and carabiner at the end of the stem. The SLCD is used by pulling on the "trigger" (a small handle) so that the cams retract together, then inserting it into a crack or pocket in the rock and releasing the trigger to allow the cams to expand. A pull on the rope, such as that generated by a climber falling, will cause a properly placed SLCD to convert the pulling force along the stem of the unit into outwards pressure on the rock, producing massive amounts of friction and preventing the removal of the unit from the rock. Due to the large forces exerted on the rock when an SLCD is fallen on, it is very important that SLCDs are only placed in solid, strong rock. History V ...

Bolt (climbing)
In rock climbing, a bolt is a permanent anchor fixed into a hole drilled in the rock as a form of climbing protection. Most bolts are either self-anchoring expansion bolts or fixed in place with liquid resin. Climbing routes that are bolted are known as sport climbs, and those that do not use (or allow) bolts, are known as traditional climbs. Description While bolts are commonplace in rock and gym climbing there is no universal vocabulary to describe them. Generally, a bolt hanger (or a fixed hanger) is a combination of a fixed bolt and a specialized stainless steel hanger designed to accept a carabiner, whereas in certain regions a bolt runner (or a carrot) describes a hangerless bolt (where the climber must provide their own hanger bracket such as a rivet hanger). A climbing rope is then clipped into the carabiner. Generally quickdraws or slings are employed between bolt hangers and the rope to reduce drag when ascending, belaying and rappelling.

Climbing Routes
A climbing route () is a path by which a Climbing, climber reaches the top of a mountain, a rock face or an ice-covered obstacle. The details of a climbing route are recorded in a climbing guidebook and/or in an online climbing-route database. Details recorded will include elements such as the type of climbing route (e.g. bouldering route, sport climbing route, traditional climbing route, ice climbing route, and alpine climbing route, etc.), the Grade (climbing), difficulty grade of the route–and beta (climbing), beta on its crux (climbing), crux(es)–and any risk or commitment grade, the length and number of pitch (climbing), pitches of the route, and the climbing equipment (e.g. climbing protection gear) that is needed to complete the route. There are definitions as to what is a valid ascent of a route (e.g. the redpoint (climbing), redpoint in rock climbing), and the class or style of ascent (e.g. onsighted, flash (climbing), flashed). The coveted first ascent (FA), first f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grappling Hook
A grappling hook or grapnel is a device that typically has multiple hooks (known as ''claws'' or ''flukes'') attached to a rope or cable; it is thrown, dropped, sunk, projected, or fastened directly by hand to where at least one hook may catch and hold on to objects. Generally, grappling hooks are used to temporarily secure one end of a rope. They may also be used to dredge for submerged objects. The device was invented by the Romans in approximately 260 BC. The grappling hook was originally used in naval warfare to catch ship rigging so that it could be boarded. Design A common design has a central shaft with a hole ("eye") at the shaft base to attach the rope, and three or four equally spaced hooks at the end, arranged so that at least one is likely to catch on some protuberance of the target. Some modern designs feature folding hooks to resist unwanted attachment. Most grappling hooks are thrown by hand, but some used in rescue work are propelled by compressed air (e.g. ...

Sling (climbing Equipment)
A sling is an item of climbing equipment consisting of a tied or sewn loop of webbing. These can be wrapped around sections of rock, hitched to other pieces of equipment, or tied directly to a tensioned line using a Prusik style knot. They may be used as anchors, to extend an anchor to reduce rope drag, in anchor equalization, or to climb a rope. Uses In 1957 Jan and Herb Conn wrote an article titled "the versatile runner" with a long list of uses, which is still quite accurate: # Slings and now more often 3-foot alpine draws or shorter quickdraws are used in-between pieces of protection and the rope to minimize rope drag # Hitch around a chock stone or a tree to use as passive protectionConn, Jan and Herb (November 1957). ''The versatile runner'' - Summit (PDF) # Clove hitch around chicken heads or sling around horns # Longer slings or cordelettes can be used for equalized belay stations # Slings can be used as improvised "personal anchor system" attaching climber di ...
