Abstract

The safety device prevents lift cages or load hoists from falling. A brake shoe assembly is secured together by screwed rods and has a release lever subjected to a first horizontal tractive force freeing it from a retaining device, followed by a second rotary movement releasing a weight from one of the claws of a brake drum. After release, the lever and the cam of an electrical contact cutting off the power are returned to their initial positions, and the driving dogs are brought into positions at right angles to and each side of a finger actuating the cam.
