A dynamic rope is a specially constructed, somewhat elastic rope used primarily in rock climbing, ice climbing, and mountaineering. This elasticity, or stretch, is the property that makes the rope dynamic —in contrast to a static rope that has only slight elongation under load.
Static ropes are designed to allow relatively little stretch, which is most useful for applications such as hauling and rappelling. Dynamic rope is used to belay climbers, and is designed to stretch under a heavy load to absorb the shock of a fallen climber. Dynamic ropes manufactured for climbing are tested by the UIAA. A test of "single ...
Rope may be constructed of any long, stringy, fibrous material (e.g., rattan, a natural material), but generally is constructed of certain natural or synthetic fibres. [1] [2] [3] Synthetic fibre ropes are significantly stronger than their natural fibre counterparts, they have a higher tensile strength, they are more resistant to rotting than ropes created from natural fibres, and they can be ...
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.

Dynamic rope, more commonly used in climbing, is used in caving for belaying cavers on climbs or using ladders. Static rope, once past its useful life for abseiling, is often used for fixed aids, such as handlines on climbs. The rope may be knotted to help climbers. Rope may also be recycled for digging.
Mechanical rope ascending devices were created by Henri Brenot, and were used in France both for mountaineering and caving as early as 1934. [ 6 ] 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.
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 shock of a falling lead climber or rescue ...
