Grigri
A Grigri (styled as GriGri or 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 (specifically the anti panic handle which stopped the device from lowering when the handle was pulled too far back) 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. Mechanism of operation The Grigri ...

Assisted Braking 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 belaye ...

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 P ...

Self-belay
Rope-solo climbing or rope-soloing (or self-belaying) is a form of solo climbing (i.e. performed alone without a climbing partner), but unlike with free solo climbing, which is also performed alone and with no climbing protection whatsoever, the rope-solo climber uses a mechanical self-belay device and rope system, which enables them to use the standard climbing protection to protect themselves in the event of a fall. Rope-soloing can be performed as free climbing in a traditional climbing or a sport climbing format. It can also be performed as aid climbing, and a modified version can be performed as top rope soloing. Due to the complexity of the self-belay system, and the greater workloads, it is still considered a hazardous technique. Versions of rope-solo climbing have been used by solo alpine climbers, including by French alpinist Catherine Destivelle, and Italian alpinist Walter Bonatti. Rope-solo climbing techniques have also been used on big wall climbing routes b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gris-gris (talisman)
Gris-gris (, also spelled grigri, and sometimes also "gregory" or "gerregery") is a Voodoo talisman originating in West Africa which is believed to protect the wearer from evil or bring luck, and in some West African countries is used as a purported method of birth control. It consists of a small cloth bag, usually inscribed with verses from an ancestor and a ritual number of small objects, worn on the person. Etymology Although the exact origins of the word are unknown, some historians trace the word back to the Hausa word meaning fetish. An alternative theory is that the word originates with the French meaning doll or play-thing. It has otherwise been attributed in scholarly sources to the Mandingo word meaning "magic". History The gris-gris was incorporated from the Dagomba people and it was originally associated with Islamic traditions. The Dagomba people led the Kingdom of Dagbon and several neighboring states that span present-day northern Ghana and parts of surrou ...

Big Wall Climber
Big wall climbing is a form of rock climbing that takes place on long and sheer multi-pitch routes (of ''at least'' 6–10 pitches or 300–500 metres) that require a full day, if not several days, to ascend. Big wall routes are sustained and exposed and the climbers remain suspended from the continuously sheer and vertical rock face, even sleeping hanging from the face, with limited options to sit down or escape unless they abseil down the route—a complex and risky action. It is therefore a physically and mentally demanding form of climbing. Big wall climbing is typically done in pairs in a traditional climbing format, but with the distinction that the non-lead climber usually ascends by jumaring up a fixed rope to save time and energy. It requires an extensive range of supplies and equipment over and above that of traditional climbing that is carried in haul bags, including portaledges, aid climbing equipment, poop tubes, and food and water. It requires additional techn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caving Equipment
Caving equipment is equipment used by cavers and speleologists to aid and protect them while exploring caves. The term may also be used to refer to equipment used to document caves, such as photographic and surveying equipment. Originally, cave diving equipment was quite limited, but the increasing popularity of caving during the 20th century led to the creation of specialist caving equipment and companies. Due to the greatly varying conditions of caves throughout the world, there is a multitude of different equipment types and categories. Cavers exploring a largely dry system may wear a fleece one-piece undersuit with a protective oversuit while cavers exploring a very wet cave may opt to use wetsuits. Cavers in large dry systems in the tropics and in desert climates may simply opt to wear shorts and a T-shirt. History The earliest cavers in Europe and North America were limited in their explorations by a lack of suitable equipment. Explorers of the early 1800s, when caving ...
