Rock-climbing Equipment
A wide range of equipment is used during rock or any other type of climbing that includes equipment commonly used to protect a climber against the consequences of a fall. Rope, cord and webbing Climbing ropes are typically of kernmantle construction, consisting of a core (kern) of long twisted fibres and an outer sheath (mantle) of woven coloured fibres. The core provides about 70% of the tensile strength, while the sheath is a durable layer that protects the core and gives the rope desirable handling characteristics. Ropes used for climbing can be divided into two classes: dynamic ropes and low elongation ropes (sometimes called "static" ropes). Dynamic ropes are designed to absorb the energy of a falling climber, and are usually used as belaying ropes. When a climber falls, the rope stretches, reducing the maximum force experienced by the climber, their belayer, and equipment. Low elongation ropes stretch much less, and are usually used in anchoring systems. They are al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sports Equipment
Sports equipment, sporting equipment, also called sporting goods, are the tools, materials, apparel, and gear used to compete in a sport and varies depending on the sport. The equipment ranges from balls, nets, and protective gear like helmets. Sporting equipment can be used as protective gear or a tool used to help the athletes play the sport. Over time, sporting equipment has evolved because sports have started to require more protective gear to prevent injuries. Sporting equipment may be found in any department store or specific sporting equipment shops. History and development of sports Historically many sports players have developed their own sporting equipment over time. For instance, the use of a football dates back to ancient China, between 225 BC and 220 AD. As football remains the most popular sport in the 21st century, the material of the ball has completely changed over the centuries; from being made out of animal skin, to being lined with multiple layers of polyest ...

Petzl Carabiners
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 ...

Dyneema
Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, (HMPE), it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million amu. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made. UHMWPE is odorless, tasteless, and nontoxic. It embodies all the characteristics of high-density polyethylene (HDPE) with the added traits of being resistant to concentrated acids and alkalis, as well as numerous organic solvents. It is highly resistant to corrosive chemicals except oxidizing acids; has extremely low moisture absorption and a very low coefficient of friction; is self-lubricating (see boundary lubrication); and is highly resistant to abrasion, in some forms being 15 times more resistant t ...

Rappel
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 the rope, in contrast to lowering off in which the rope attached to the person descending is paid out by their belayer. This technique is used by climbers, mountaineers, cavers, canyoners, search and rescue and rope access technicians to descend cliffs or slopes when they are too steep and/or dangerous to descend without protection. Many climbers use this technique to protect established anchors from damage. Rope access technicians also use this as a method to access difficult-to-reach areas from above for various industrial applications like maintenance, construction, inspection and welding. To descend safely, abseilers use a variety of techniques to increase the friction on the rope to the point where it can be controlled comfortably. These techniques range from ...

Maillon
A maillon, maillon rapide or quick link is a metal link, similar to a carabiner. Maillons have a threaded sleeve which tightens over a thread, as opposed to a hinged gate like a carabiner, making them stronger, but more difficult to use. Like carabiners, maillons are available in a range of shapes and thicknesses (i.e., strengths), and often offer greater versatility over carabiners as their different shapes and lack of hinged gates allow them to be used in multi-directional load situations. The word ''maillon'' comes from the French language, meaning "link". Usage Maillons are used primarily in climbing and caving. In caving, they are used to make secure and vital connections such as those required when using single rope technique,http://www.cave-crag.co.uk/721/Maillon-Rapide-10mm-Semi-Circular.html or for attaching ropes to anchor points. In climbing, they are used to construct leave-in-place abseil anchors. Maillons can also be used for fastening harnesses with a dual attachme ...

Big Wall Climbing
Big wall climbing is a type of rock climbing where a climber ascends a long multi-pitch route, normally requiring more than a single day to complete the climb. Big wall routes require the climbing team to live on the route often using portaledges and hauling equipment. It is practiced on tall or more vertical faces with few ledges and small cracks. History In the early 20th century, climbers were scaling big rock faces in the Dolomites and the European Alps employing free- and aid-climbing tactics to create bold ascents. Yet, the sheer walls were waiting to be climbed by future generations with better tools and methods. In addition, many nations in the early 1900s had specialized army units that had developed wall climbing skills for gaining surprise entry into enemy fortifications by wall climbing. In the early 1900s the Filipino Scouts, a US Army unit composed of Filipino enlisted and American officers, demonstrated their specialized skills by climbing the steep walls of ...

Sport Climbing
Sport climbing (or Bolted climbing) is a form of rock climbing that relies on permanent anchors (or bolts), permanently fixed into the rock for climber protection, in which a rope that is attached to the climber is clipped into the anchors to arrest a fall; it can also involve climbing short distances with a crash pad underneath as protection. This is in contrast to traditional climbing where climbers must place removable protection as they climb. Sport climbing usually involves lead climbing and toproping techniques, but free solo and deep-water solo (i.e. no protection) climbing on sport routes is also sometimes possible. Since sport climbing routes do not need to follow traditional climbing route lines where protection can be placed into natural features (e.g. cracks), they tend to follow more direct lines up crags. This aspect, in addition to the lack of any need to install protection during the climb (e.g. the sport climber just clips into pre-installed bolts along th ...

Lead Climbing
Lead climbing is a climbing style, predominantly used in rock climbing. In a roped party one climber has to take the lead while the other climbers follow. The ''lead climber'' wears a harness attached to a climbing rope, which in turn is connected to the other climbers below the lead climber. While ascending the route, the lead climber periodically connects the rope to protection equipment for safety in the event of a fall. This protection can consist of permanent bolts, to which the climber clips quickdraws, or removable protection such as nuts and cams. One of the climbers below the lead climber acts as a belayer. The belayer gives out rope while the lead climber ascends and also stops the rope when the lead climber falls or wants to rest. A different style than lead climbing is top-roping. Here the rope is preattached to an anchor at the top of a climbing route before the climber starts their ascent. Lead climbing as a discipline of sport climbing debuted at the 2020 Summ ...
