Abstract

There is provided a height rescue apparatus comprising a safety line (1) which is attached at (3) to a flexible elongate element (2) which has a lower tensile strength than the safety line 1 which is wound on a drum (9) which is part of a speed control means. A friction device (5) acts on a portion of the safety line (1) to reduce tension in said portion of the safety line by at least 50% in a full arrest situation. The drum (9) or the speed control means is held in a first position which prevents rotation of the drum and release means can be actuated after the fall arrest to allow the drum to provide a controlled lowering action.
