Swiss soldiers abseiling using the Dülfersitz Abseiling by means of the Dülfersitz (not free-hanging). The Dülfersitz (named after mountaineer Hans Dülfer who had developed a different but related technique [1] [2]), also known as body rappel, is a classical, or non-mechanical abseiling technique, used in rock climbing and mountaineering.
Abseiling (/ ˈ æ b s eɪ l / AB-sayl or / ˈ ɑː p z aɪ l / AHP-zyle; from German abseilen 'to rope down'), also known as rappelling (/ ˈ r æ p ɛ l / RAP-pell or / r ə ˈ p ɛ l / rə-PELL; from French rappeler 'to recall, to pull through'), is the controlled descent of a steep slope, such as a rock face, by moving down a rope.
For safe single-rope technique, especially on drops with complex rigging with intermediate belays, it is essential that the abseiling device can be removed from the rope without being unclipped from the harness. This is a problem with the simplest device, the single piece figure eight. These also twist the rope, which is a problem if there is a ...
Sit harness. A climbing harness is a piece of equipment that allows a climber to tie in to the safety of a rope. [1] It is used in rock and ice climbing, abseiling, and lowering; this is in contrast to other activities requiring ropes for access or safety such as industrial rope work (such as window cleaning), construction, and rescue and recovery, which use safety harnesses instead.
Belay devices usually attach to the harness of the belayer via a carabiner, and are usually made of aluminium or an alloy. Some belay devices can also be used as descenders for a controlled descent on a rope, that is abseiling or rappeling. Many belay devices can be used to control either one rope, or two ropes in parallel.
The figure-eight cannot be removed from the rope without detaching the device from the harness, and so could be accidentally dropped, particularly when tackling a rebelay. They also twist the rope which is a particular problem where a rebelay prevents the rope from untwisting.
RANTOUL, Ill. (WCIA) — Thanks to the Experimental Aircraft Association, you can experience traveling the way people did 100 years ago. They have a 1929 Ford Tri-Motor airplane at the Rantoul ...
A soldier abseiling with a Munter hitch, depicted in a German military publication from 1966. This hitch can be used to rappel or abseil down a vertical or semi-vertical wall, although it is not recommended as it causes severe twisting of the rope. Proper training should be undertaken before using the Munter hitch to rappel.
