Abstract

See full text

A safety brake for a load lifting gear includes an actuator for a locking pawl, a brake-locking gear element connected to a lifting gear drive, pawl position monitoring sensors and a controller. The controller monitors the sensors and the lifting gear speed, and operates the lifting gear drive and the actuator to brake the lifting gear against excessive speed, by moving the actuator between energized and non-energized states and differentiating with sensor inputs among a detached state, a bearing state and a fully engaged state of the locking pawl with a pawl clearance of the brake-locking gear element.
