A Petzl Croll is an ascending device [1] used in caving and industrial rope access made by the French company Petzl. Its name comes from the town Crolles where Petzl's company headquarters are located but might also be a reference to the nearby cave system of the Dent de Crolles , the exploration of which triggered a lot of technical effort ...
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 ...
This version also saw Petzl shift the intended use of the Stop to recreational only use. The 2019 version of the Stop is no longer certified for Industrial use and Petzl now sell products such as the Petzl Rig and Petzl I'D S [3] for Industrial use instead. Rope compatibility: 8.5 to 11 mm low stretch kernmantle rope; Fixed stainless steel bobbins
Rope access technicians descend, ascend, and traverse ropes for access and work while suspended by their harnesses. Sometimes a work seat may be used. Sometimes a work seat may be used. The support of the rope is intended to eliminate the likelihood of a fall altogether, but a backup fall arrest system ( Personal protective equipment ) is used ...
After 1933 Petzl began making rope ladders for his own use, developed a scaling-pole in 1940, and began testing the first nylon ropes in 1942. In 1968 Bruno Dressler asked Petzl, who worked as a metals machinist, to build a rope-ascending tool he had developed, and in the 1970s Petzl started a small caving equipment manufacturing company that ...

Each segment of the rope is pulled by the two neighboring segments, stressing the segment in what is also called tension. Tension is the pulling or stretching force transmitted axially along an object such as a string, rope, chain, rod, truss member, or other object, so as to stretch or pull apart the object.
Articles related to chains, serial assemblies of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension.
