Abstract:
A combination descender, pulley, and force limiting rope brake for rope rescue has a supporting plate having a one-way pulley sheave rotatably mounted thereto for free-wheeling rotation of the sheave in only a first rotational direction. A fixed brake member is mounted rigidly to the supporting plate. A movable brake member is pivotally mounted to the supporting plate. A pinching opening is defined by the gap. The rope passes in a first direction through the gap when the sheave is free-wheeling in the first rotational direction. The movable brake member translates relative to the fixed brake member in cooperation with rotation of the sheave. Rotation-under-load of the sheave in an opposite rotational direction urges translation of the movable brake member towards the fixed brake member from an open position, wherein the pinching opening is open sufficiently to allow the rope to freely pass therethrough, to a closed position wherein the movable brake member closes the pinching opening so as to frictionally pinch the rope at a preset minimum opening of the pinching opening.
