A static rope, or a semi-static rope is a low-elongation rope that is designed to stretch minimally when placed under load; typically less than 5%. In contrast, a dynamic rope is designed to stretch up to 40%. [1] Static ropes have a wide variety of use, for instance in fire rescue operations [2] and caving. [3]
Static ropes have some applications in climbing, such as for hauling gear, abseiling, and top-roping in some situations. [4]
Lead climbing is always done with a dynamic rope, since a fall on a static rope would be stopped too quickly [5] and could lead to serious injury. [6] [7]
Rated static ropes usually conform to the EN 1891 standard split into EN 1891 Type A, and EN 1891 Type B. Type A ropes are intended for general use due to their superior strength; wheras, type B ropes are intended for use in specialised circumstances where the usually thinner diameter and lower weight are critical for an operation.
