Assisted Braking Device
A belay device is a mechanical piece of climbing equipment used to control a rope during belaying. It is designed to improve belay safety for the climber by allowing the belayer to manage their duties with minimal physical effort. With the right belay device, a small, weak climber can easily arrest the fall of a much heavier partner. Belay devices act as a friction brake, so that when a climber falls with any slack in the rope, the fall is brought to a stop. Typically, when the rope is held outward, away from the body, it moves relatively freely, so the belayer can take up or pay out slack. When the rope is brought backward, to the side of the body, the rope is forced into tight bends and rubs against the device and/or against itself, allowing the belayer to arrest the descent of a climber in the case of a fall. This rubbing slows the rope, but also generates heat. Some types of belay devices can arrest a fall without the belayer taking any action, while others require the belaye ...

Petzl Belay Devices
Petzl is a French manufacturer of climbing gear, caving gear, work-at-height equipment, and headlamp (outdoor), headlamps based in Crolles (near Grenoble), France. The company was created by the cave explorer Fernand Petzl in the mid-1970s. Their three specialties are: *Vertical sports: equipment for mountaineering, climbing, caving, etc. *Work at height and rescue: solutions for progression and safety in difficult-access worksites and in technical rescue. *Headlamps (head torches) that provide hands-free lighting. History Fernand Petzl, born in 1912, began his caving career in the late 1920s and early 1930s. In 1936, Petzl was introduced to, then small-time caver, Pierre Chevalier. The two began work on improving the technology behind their sport. In 1943, Chevalier designed and tested the first nylon rope to replace caving ladders. This technology provided the foundation for nearly all vertical safety methods to come. Chevalier's innovation led to the first 1,000 meter cave ...

Rock-climbing Equipment
Rock-climbing equipment varies with the specific type of climbing that is undertaken. Bouldering needs the least equipment outside of climbing shoes, climbing chalk and optional crash pads. Sport climbing adds ropes, harnesses, belay devices, and quickdraws to clip into pre-drilled bolts. Traditional climbing adds the need to carry a "rack" of temporary passive and active protection devices. Multi-pitch climbing, and the related big wall climbing, adds devices to assist in ascending and descending fixed ropes. Finally, aid climbing uses unique equipment to give mechanical assistance to the climber in their upward movement (e.g. aiders). Advances in equipment are a key part of the rock climbing history, starting with the climbing rope. Modern devices enable climbers to perform tasks previously done manually, with greater control – in all conditions – and with less effort. Examples of replacements include the harness (replaced tying the rope around the waist), th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capstan Equation
The capstan equation or belt friction equation, also known as Euler–Eytelwein formula (after Leonhard Euler and Johann Albert Eytelwein), relates the hold-force to the load-force if a flexible line is wound around a cylinder (a bollard, a winch or a Capstan (nautical), capstan). It also applies for fractions of one turn as occur with rope drives or band brakes. Because of the interaction of frictional forces and tension, the tension on a line wrapped around a capstan may be different on either side of the capstan. A small ''holding'' force exerted on one side can carry a much larger ''loading'' force on the other side; this is the principle by which a capstan-type device operates. A holding capstan is a ratchet device that can turn only in one direction; once a load is pulled into place in that direction, it can be held with a much smaller force. A powered capstan, also called a winch, rotates so that the applied tension is multiplied by the friction between rope and caps ...

Belaying
In climbing and mountaineering, belaying comprises techniques used to create friction within a climbing protection system, particularly on a climbing rope, so that a falling climber does not fall very far. A climbing partner typically applies tension at the other end of the rope whenever the climber is not moving, and removes the tension from the rope whenever the climber needs more rope to continue climbing. The belay is the place where the belayer is anchored, which is typically on the ground, or on ledge (where it is also called a belay station) but may also be a hanging belay where the belayer themself is suspended from an anchor in the rock on a multi-pitch climbing, multi-pitch climb. Description Belaying is a critical part of climbing safety. Correct belaying methods allow a belayer to hold the entire weight of the climber with relatively little force and easily arrest falls. In its simplest form, a belay consists of a rope that runs from a climber to another person ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climbing Wall
A climbing wall is an artificially constructed wall with manufactured grips (or "holds") for the hands and feet. Most walls are located indoors, and climbing on such walls is often termed indoor climbing. Some walls are brick or wooden constructions but on 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 su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solo Climbing
Solo climbing (or soloing) is a style of climbing in which the climber ascends a climbing route alone and deliberately without the assistance of a belayer (or "second"), or being part of any rope team. By its very nature, solo climbing presents a higher degree of risk to the climber as they are entirely relient on their own skills and equipment and any problems may require a self-rescue. Solo climbing is most common in mountaineering and more laterly in the sub-discipline of alpine climbing. The most dangerous form of solo climbing is free solo climbing, which means both climbing alone and without any form of climbing protection, and was dramatically portrayed in the climbing films, ''Free Solo'' (in rock climbing) and ''The Alpinist'' (in ice climbing and in alpine climbing). With climbing protection The following types of solo climbing use some form of climbing protection, which typically involves around a mechanical self-locking device (or progress capture/assisted brak ...

Wren Industries Silent Partner
Wrens are a family, Troglodytidae, of small brown passerine birds. The family includes 96 species and is divided into 19 genera. All species are restricted to the New World except for the Eurasian wren that is widely distributed in the Old World. In Anglophone regions, the Eurasian wren is commonly known simply as the "wren", as it is the originator of the name. The name ''wren'' has been applied to other, unrelated birds, particularly the New Zealand wrens (Acanthisittidae) and the Australian wrens (Maluridae). Most wrens are visually inconspicuous though they have loud and often complex songs. Exceptions include the relatively large members of the genus ''Campylorhynchus'', which can be quite bold in their behaviour. Wrens have short wings that are barred in most species, and they often hold their tails upright. Wrens are primarily insectivorous, eating insects, spiders and other small invertebrates, but many species also eat vegetable matter and some eat small frogs and liza ...
