A carabiner or karabiner, often shortened to biner or to crab, colloquially known as a (climbing) clip, is a specialized type of shackle, a metal loop with a spring-loaded gate used to quickly and reversibly connect components, most notably in safety-critical systems. The word comes from the German Karabiner, short for Karabinerhaken, meaning "carbine hook," as the device was used by carabiniers to attach their carbines to their belts.
Tree climbing is a recreational or functional activity consisting of ascending and moving around in the crowns of trees.
Glossary of climbing terms relates to rock climbing, mountaineering, and to ice climbing.
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.
Abseiling, also known as rappelling, is the controlled descent of a steep slope, such as a rock face, by moving down a rope. When abseiling, the person descending controls their own movement down a static or fixed rope, in contrast to lowering off, in which the rope attached to the person descending is paid out by their belayer.
Crevasse rescue is a set of techniques in mountaineering where climbers use their equipment to pull a climber, who has just fallen into a crevasse, to safety. Crevasse rescue is considered a core skill set in alpine climbing, but difficult to do efficiently. It is typically encountered by rope teams on glaciers.
Solo climbing is a style of climbing in which the climber ascends a climbing route alone and deliberatly without the assistance of a belayer, 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.
Self-locking devices are pieces of rock-climbing equipment intended to arrest the fall of solo climbers who climb without partners. This device is used for rope solo climbing, for "ground-up climbing", and for "top rope solo climbing". To date, several types of self-locking devices have evolved.
The Munter hitch, also known as the Italian hitch, mezzo barcaiolo or the crossing hitch, is a simple adjustable knot, commonly used by climbers, cavers, and rescuers to control friction in a life-lining or belay system. To climbers, this hitch is also known as HMS, the abbreviation for the German term Halbmastwurfsicherung, meaning half clove hitch belay. This technique can be used with a special "pear-shaped" HMS locking carabiner, or any locking carabiner wide enough to take two turns of the rope.
The Bachmann hitch is a friction hitch, named after the Austrian alpinist Franz Bachmann. It is useful when the friction hitch needs to be reset quickly or often or made to be self-tending as in crevasse and self-rescue.
In climbing and mountaineering, a fixed-rope is the practice of installing networks of in-situ anchored static climbing ropes on climbing routes to assist any following climbers to ascend more rapidly—and with less effort—by using mechanical aid devices called ascenders. Fixed ropes also allow climbers to descend rapidly using mechanical devices called descenders. Fixed ropes also help to identify the line of the climbing route in periods of low visibility. The act of ascending a fixed rope is also called jumaring, which is the name of a type of ascender device, or also called jugging in the US.
About the true history of this knot, the inventor is a frenchman, E Gérard, who published this knot 3 years previous Prusik's publication (1931) in the magazine La Montagne : revue mensuelle du Club alpin français | 1928-01-01 | Gallica, it's also republished in 1929 by Blanchet, E. R. : «The Spare Rope in Theory and Practice », in : Alpine Journal, mai 1929, pp. 63-75 , in 1929 in Österreichische Alpenzeitung, décembre 1929, pp. 230-232 '. Mr Prusik was perfectly aware of this but none the less stole this discovery and published it in 1931.
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.
Single-rope technique (SRT) is a set of methods used to descend and ascend on the same single rope. Single-rope technique is used in caving, potholing, rock climbing, canyoning, roped access for building maintenance and by arborists for tree climbing, although to avoid confusion in the tree climbing community, many have taken to calling it "stationary" rope technique.
In climbing, a Tyrolean traverse is a technique that enables climbers to cross a void between two fixed points, such as between a headland and a detached rock pillar, or between two points that enable the climbers to cross over an obstacle such as chasm or ravine, or over a fast moving river. Originally developed by Tyrolean mountaineers in the Dolomites in the late 19th to early 20th century, Tyrolean traverses are used in other areas including in caving and in mountain rescue situations.
An autoblock is a rope device used in climbing and caving for both rappelling (downward) and ascending (upward).
A pit cave, shaft cave or vertical cave—or often simply called a pit and pothole or pot ; jama in Slavic languages scientific and colloquial vocabulary —is a type of cave which contains one or more significant vertical shafts rather than being predominantly a conventional horizontal cave passage. Pits typically form in limestone as a result of long-term erosion by water. They can be open to the surface or found deep within horizontal caves. Among cavers, a pit is a vertical drop of any depth that cannot be negotiated safely without the use of ropes or ladders.
A Grigri is an assisted braking belay device manufactured by Petzl designed to help secure rock-climbing, rappelling, and rope-acrobatic activities. Its main characteristic is a clutch that assists in braking under a shock load. The success of this device has led to grigri becoming a common name for devices of this type. In 2011 a new version, the Grigri 2, was released to replace the original 1991 model. Petzl released the Grigri+ in 2017, adding new safety features to the original design. However this made the device heavier and many climbers felt the new safety features got in the way of normal operation when lowering. 2019 saw the release of an updated version of the device, simply called the Grigri. It is named for the African amulet gris-gris, believed to protect the wearer from evil.
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.
The Dülfersitz, also known as body rappel, is a classical, or non-mechanical abseiling technique, used in rock climbing and mountaineering. It is not used frequently any more, since the introduction of belay devices. In the Dülfersitz, the rope is wound around the body, and the speed of descent is controlled using the friction of the rope against the body.
