A Purcell Prusik is a related cord popular among cavers and rope-rescue people. A somewhat longer loop than the normal Prusik is used around the rope, then a second Prusik is used around the cord loop itself to form a foot loop. The foot loop is then easily adjusted in length and position. A Prusik-Minding-Pulley is common in rope rescue. The ...
A 240 centimetres (94 in) Sling A climbing anchor equalized using dyneema slings. 1957 article on use of slings by Jan and Herb Conn.. A sling is an item of climbing equipment consisting of a tied or sewn loop of webbing.
The first mechanical rope ascending devices were created by Henri Brenot, and were used in France both for mountaineering and caving as early as 1934. [ 5 ] A popular example of the ascender is the jumar, named for its inventors Adolph Jüsi and Walter Marti and the Swiss firm Jümar Pangit they created to manufacture it, beginning in 1958.
This technique is mostly used for Dyneema ropes. [8] The principle of a Dyneema eye is a core-to-core splice, in which a length of at least 60 times the diameter of the rope is taken back into itself. DSM advises using 60 times the diameter for coated Dyneema, and 100 times the diameter for uncoated Dyneema. For 6mm coated rope, this would mean ...
Cave rescue borrows elements from firefighting, confined space rescue, rope rescue and mountaineering techniques but has also developed its own special techniques and skills for performing work in conditions that are almost always difficult and demanding. Since cave accidents, on an absolute scale, are a very limited form of incident, and cave ...

Crevasse rescue (or crevasse-extraction) 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. [1] Crevasse rescue is considered a core skill set in alpine climbing, but difficult to do efficiently. [1] [2] It is typically encountered by rope teams on ...
Dyneema Composite Fabric (DCF), also known as Cuben Fiber (CTF3), is a high-performance non-woven composite material used in high-strength, low-weight applications. It is constructed from a thin sheet of ultra-high-molecular-weight polyethylene ( UHMWPE , "Dyneema") laminated between two sheets of polyester .
