Petzl Stop
A Petzl Stop is a descender used primarily in caving and formerly used for industrial rope access made by the French company Petzl. Usage The Stop is for use with single low stretch kernmantle ropes and is usually attached to the harness via a carabiner A carabiner or karabiner () 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 is a shortened form of ''Karabinerhaken'' .... The rope is then threaded through the cam and bobbin by undoing the safety clip and moving the swinging side plate to the side. The swinging side plate facilitates insertion and removal of the rope without the need to disconnect it from the harness, making it less likely to be dropped while inserting and removing the rope from the Stop while at height. As the Stop is a self-braking descender, an unintentional release of the deadman's handle should stop the descent, due to the asymme ...

Belay 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 belayer ...

Caving
Caving – also known as spelunking in the United States and Canada and potholing in the United Kingdom and Ireland – is the recreational pastime of exploring wild cave systems (as distinguished from show caves). In contrast, speleology is the scientific study of caves and the cave environment.Caving in New Zealand (from Te Ara: The Encyclopedia of New Zealand, Accessed 2012-11.) The challenges involved in caving vary according to the cave being visited; in addition to the total absence of light beyond the entrance, negotiating pitches, squeezes, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petzl
Petzl is a French manufacturer of climbing gear, caving gear, work-at-height equipment, and 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 descent when Petzl exp ...

Carabiner
A carabiner or karabiner () 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 is a shortened form of ''Karabinerhaken'' (or also short ''Karabiner''), a German phrase for a "spring hook" used by a carbine rifleman, or carabinier, to attach his carabin to a belt or bandolier. Use Carabiners are widely used in rope-intensive activities such as climbing, fall arrest systems, arboriculture, caving, sailing, hot air ballooning, rope rescue, construction, industrial rope work, window cleaning, whitewater rescue, and acrobatics. They are predominantly made from both steel and aluminium. Those used in sports tend to be of a lighter weight than those used in commercial applications and rope rescue. Often referred to as carabiner-style or as mini-biners, carabiner keyrings and other light-use clips of similar style and design have also become popular. Most ar ...
