Abstract:
A disk brake for an elevator drive having a traction sheave connected to a brake disk, the disk brake comprising:a pair of brake levers each having a fulcrum end for pivotal mounting and a free end; a pair of brake linings, each said brake lining being attached to an associated one of said brake levers between said fulcrum end and said free end; a pair of compression springs, each said compression spring acting upon an associated one of said brake levers between said brake lining and said free end; and a brake release means acting on said brake levers whereby when said the brake levers are pivotally mounted on a casing of an elevator drive on opposite sides of a brake disk of the elevator drive with said fulcrum ends adjacent one another said brake linings adjacent opposite surfaces of the brake disk, said compression springs force said brake linings into engagement with the brake disk to prevent rotation of a connected traction sheave to bring the elevator drive to a standstill, and said brake levers being released by selective actuation of said brake release means acting on said brake levers against a force of said compression springs, said brake release means including a pair of manually remotely actuatable cam levers movable about a fulcrum point, each of said cam levers being engagable with an associated one of said brake levers to move said brake levers against the force of said compression springs.
