    • A device for remotely opening the safety latch of a hook characterized by an actuating link attached to the safety latch that is selectively movable between a first position, opening the safety latch, and a second position, closing the safety latch. The device further includes actuator, a transmitter and a receiver. The actuator engages the actuating link and selectively moves the actuating link between the first position and the second position. The transmitter transmits operating commands, inputted by the user, to the receiver. The receiver controls the actuator and causes the actuator to selectively move the actuating link between the first position and the second position in response to operating commands from the transmitter.
