A Tensionless hitch is an anchor knot used for rappelling or rope rescue. Unlike most knots, the tensionless hitch retains a 100% efficiency rating, [ 3 ] meaning the strength of the knot is equal to the strength of the rope; it is not a significant stress riser .
Particularly useful in rope tightening systems where the loop is established as a means to secure a pulley or carabiner onto the main line to reduce the amount of work needed to tighten the entire system. Similar to a trucker's hitch.
A radium release hitch is a load-releasing hitch using 3:1 mechanical advantage which is used in a two-rope technical rescue system. [1] The Radium Release Hitch allows a load to be transferred from one rope to another and is commonly rigged into the belay line prior to the operation of a two-rope technical rescue system.
A climber and a belayer using a climbing rope. A climbing rope is a rope that is used in climbing.It is a critical part of an extensive chain of protective equipment (which also includes climbing harnesses, anchors, belay devices, and carabiners) used by climbers to help prevent potentially fatal fall-related accidents.
Figure-eights offer a smooth controlled descent when rappelling and lowering climbers. [1] They can be used with nearly any diameter climbing rope and don't get as hot as other friction devices because of their ability to dissipate heat efficiently. [2]
Center is a standard carabiner rating. Using a carabiner to connect to a rope. A carabiner or karabiner (/ ˌ k ær ə ˈ b iː n ər /), [1] often shortened to biner or to crab, colloquially known as a (climbing) clip, is a specialized type of shackle, a metal loop with a spring-loaded gate [2] used to quickly and reversibly connect components, most notably in safety-critical systems.
Non-locking (top) and locking (bottom) carabiners. Carabiners are closed metal clips with spring-loaded gates that are used as connectors between the rope and various devices. Modern carabiners are made from a lightweight but strong aluminum alloy that can withstand the load of a fall. Carabiners come in various shapes, with the asymmetric ...
An alternative V-shaped form of the death triangle involves clipping a single loop of webbing or cord to both anchors, then clipping the third carabiner over the loop rather than through it, allowing the latter to slip off the loop if either anchor fails. Two better methods are (a) putting a half twist in the cord and clipping the free ...
