Abstract
A safety brake of the type for use in hoist. As a hoist cage descends or ascends faster than a predetermined safety speed, a corresponding high speed motion is transmitted to a main shaft of the safety brake through a input pinion gear connected to the main shaft for engagement with a vertical rack attached to a hoist tower. Movable braking disks are attached to the main shaft for rotation therewith. Fixed braking disks are interleaved with the movable disks. Such high speed motion causes a dog retained in the main shaft to centrifugally move outwardly to engage the drum. The actuator assembly connected to the drum acts to cause the drum to move against the fixed and movable braking disks.
