Rope rescue exercise on the Cologne Cable Car. Rope rescue is a subset of technical rescue that involves the use of rope, be it steel or cable rope, or more commonly used nylon, polyester, or other type of rope. Kernmantle (kern = core and mantle = sheath) rope as it is called, is available in various types: dynamic (stretches to absorb the ...
A Z-Drag or Z-Rig is an arrangement of lines and pulleys, effectively forming a block and tackle, that is commonly used in rescue situations. [1] The basic arrangement results in pulling the hauling end 3 times the distance the load is moved, providing a theoretical mechanical advantage of three to one .
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 .
For example, rope used in caving is generally exposed to increased abrasion, so the mantle is woven more tightly than rope used in climbing or rappelling. However, the resulting rope is cumbersome and difficult to tie knots in. Kernmantle construction may be used for both static and dynamic ropes. Static ropes are designed to allow relatively ...
Made with suitable rope by qualified personnel this knot can be used as a rescue harness capable of supporting a person while being hoisted or lowered to safety. One loop supports the body, around the chest and under the arms, and the other loop supports the legs, under the knees.
Cave rescue borrows elements from 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 rescue is a ...
Swift water rescue (also called "white water rescue") is a subset of technical rescue dealing in white water river conditions. Due to the added pressure of moving water, swift water rescue involves the use of specially trained personnel, ropes and mechanical advantage systems that are often much more robust than those used in standard rope rescue .
For climbing on with a fixed rope attached for security (for example, to snow anchors on a steep slope) only one ascender is used, keeping the other hand free for holding an ice axe. Ascenders are not used on free climbing routes, where a climber uses only their hands and feet on the features of the rock without artificial aids to gain ...
