A braking device for an elevator.

摘要

A braking device for an elevator, wherein a cage (3) moves along a guide rail. The braking device includes a wedge braking device (10) a speed governor (20) and a linking mechanism. The wedge braking device (10) has wedges (14) which are pressed against the guide rail (2) thereby stopping the cage (3) when the speed governor (20) senses an excess speed or when a weight responsive mechanism senses a fall in weight. The wedge braking device (10) has an hydraulic release mechanism.
