Rock-climbing equipment
Rock-climbing equipment varies with the specific type of climbing that is being undertaken by the climber(s). Bouldering needs the least equipment: climbing shoes, climbing chalk and optional crash pads. Sport climbing adds ropes, harnesses, belay devices, and quickdraws which clip into pre-drilled permanently-fixed bolts on the rock face. Traditional climbing adds the need to carry a "rack" of temporary and removable passive and active protection devices. Multi-pitch climbing, and the related big wall climbing, adds devices to assist in ascending and descending static fixed ropes. Finally, aid climbing uses unique equipment to give mechanical assistance to the climber in their upward movement (e.g. aiders).
Advances in rock-climbing equipment design and manufacture are a key part of the rock climbing history, starting with the climbing rope. Modern rock-climbing devices enable climbers to perform tasks that were previously done manually, but with greater control – in all conditions – and with less effort. Examples of such replacements include the harness (replaced tying the rope around the waist), the carabiner (replaced many knots), the descender/abseil device (replaced the dülfersitz), the ascender (replaced the prusik knot), the belay device (replaced the body belay), and nuts/hexes (replaced chockstones).
Modern rock-climbing equipment includes dynamic ropes, plyometric training tools, advanced spring-loaded camming devices (SLCDs) for protection, and advanced rope control devices such as self-locking devices (SLDs), progress capture devices (PCDs), and assisted braking devices (ABDs). Modern equipment uses advanced materials that are increasingly more durable, stronger, and weigh less (e.g. spectra/dyneema and aluminum alloys) than traditional equipment. The equipment must meet specific quantative standards (e.g. the UIAA standards) for strength, durability, and reliability, and must be certified and tested against such standards with individual pieces of equipment carrying such certification marks.
The rock-climbing equipment needed varies materially depending on the type of rock climbing being undertaken. Starting from the least equipment-intensive type of climbing, the general equipment needs are as follows:
Rock-climbing equipment is broadly classed as Personal Protective Equipment (PPE). The International Climbing and Mountaineering Federation (known as the UIAA) was an important early body—and the only body pre-1995—in setting standards for climbing equipment. The UIAA Safety Commission continues to play a central worldwide role in this area. The European Committee for Standardization (CEN) is also an important major regulatory body for PPE, and which works closely with the UIAA Safety Commission through its CEN Working Group for Mountaineering Equipment.
North America has fewer specific regulations as rock-climbing equipment is not classed as military or professional PPE and thus does not fall under the American Occupational Safety and Health Administration (OSHA) regulations; in effect, the UIAA and CEN have become the most important bodies for setting standards and regulating rock-climbing equipment worldwide, and most major manufacturers, and distributors, produce equipment certified and stamped with UIAA and CE marking. After the United Kingdom left the European Union, it adopted the UKCA certification in place of the CEN.
Modern climbing ropes are 50–80 metres (160–260 ft) in length—the longer versions are for multi-pitch climbing—and have a kernmantle construction consisting of a core kern of twisted nylon fibers and an outer sheath mantle of woven colored coarse nylon fibers. They are either dynamic ropes, which can stretch to absorb the energy of a falling climber, or are the less expensive but more hard-wearing static ropes, which are only for use in constant-load situations such as descending (e.g. abseiling) and ascending (e.g. jumaring).
Some climbers will use a single full-thickness climbing rope with a diameter of approximately 9 to 11 mm (0.35 to 0.43 in), and some will use double ropes, or "half-ropes", to reduce rope drag (e.g. one rope is clipped into any given anchor or protection point), which have a reduced thickness of approximately 8 to 9 mm (0.31 to 0.35 in) to limit the weight of the extra rope. Twin roping uses two thinner ropes, typically 7 to 8 mm (0.28 to 0.31 in) in thickness, which are both clipped into each protection point. Twin roping is thus not used for reducing rope drag, but to have a backup rope on long climbs.
