BRAKE APPARATUS FOR THE ELEBATOR

摘要

Disclosed herein is a brake apparatus for elevators, which simplifies the construction of a gear assembly for operating a hydraulic generator, and ensures stability. The brake apparatus includes an outer drum mounted to the elevator. An inner drum is rotatably supported in the outer drum. A pinion is supported via a shaft to the inner drum in such a way as to engage with the rack and extends a fly weight when the elevator falls, thus rotating the inner drum. A drive gear is integrally provided on the outer circumferential surface of the inner drum and engages with a driven gear of a hydraulic generator. A hydraulic cylinder is coupled to the hydraulic generator and generates braking force in a predetermined direction such that the elevator is not forced away from the rail.
