ABSTRACT:
A hand operated safety device for controlling the descent of a person along a guide track affixed to the exterior face of a building wall. The descent device is clamped to the track and includes a hydraulically operated brake which can be actuated to vary the frictional force between the descent device and the track surface to control the speed of descent. The device includes a preset mechanism for applying a fixed clamping force to the track depending on the user's weight. In a second embodiment, the track is a rail of triangular cross section having a continuous rack which is engaged by a brake operated spur gear on the descent device. A user wearable harness is slung beneath the descent device for lowering the person to the ground.
