ABSTRACT OF THE DISCLOSURE A remote controlled safety hook assembly is provided herein. The assembly includes a supporting frame, a hook-shaped member rotatably dis- posed within the supporting frame, at least one shackle means suspended from the supporting frame, a power supply means disposed in the supporting frame, a receiver means for receiving specific control signals disposed in the supporting frame and a relay means operatively connected with the receiver means, drive means disposed in the supporting frame, a gear assembly operatively connected with the drive means and the hook-shaped member for automatically swinging the hook-shaped member from a closed position to an open position in response to specified control signals and a cut-off switch means and a close switch means disposed for engagement with the hook-shaped member in its open position, both of the switch means releasing all electrical power to the hook-shaped member when the hook- shaped member is open and the close switch means simultaneously disengaging the receiver means and the relay means from the hook-shaped member, thus preventing possible damage to the receiver means, the relay means and the power supply means. By this invention, the shackles are automatically removed after the load is properly positioned; the various components of the safety hook are protected from shock; the hook can be manually released in the event of malfunction; the hook is readily accessible and is substantially free from interference with the shackles; the hook and the shackles are independently supported; and the safety hook assembly also acts as a headache ball or weight.
