Abstract

A safety device for lifting gear, particularly for mobile cranes, to prevent accident due to uneven or sloping ground and overloading, uses a gyroscopically controlled electronic system, based on monitoring the stability of the engine, and completely controlling all electrical, electro-mechanical, pneumatic, oleo-pneumatic or hydraulic actuators used by the lifting gear. It acts as a couple limiter, operating with reference to a zero level, and is actuated as soon as the engine speed reaches a dangerous condition. The gyroscope give electrical control signals corresponding to different angles, and timed relays reverse the servo control signals, and uses a set of load detectors.
