Automatic anti-fall device for power-driven lifting machinery

摘要

The device, adapted to be associated with a motorized hauling installation, comprises a self-clamping jaws block with a safety cable passing through it onto which the load can be transferred by clamping the jaws. The jaws block is connected by means of control rods to a mobile chassis of which one end is adapted to pivot, in case of a fall, about a fixed point of the casing, this pivoting action activating an electric detector which stops the machine motor.
