The present invention a controllable hook assembly having a structurally connected main body portion between upper and lower assemblies. The main body encloses actuator that connects by a clutch to drive assembly disposed in the lower assembly whereby the clutch is configured to limit the connection to a predetermined linear force applied to the actuator. The drive assembly is configured to move a plurality of hook arms between an open and closed position and is adapted capturing a line attached to a load. A controller interacts with the actuator to energize a motor and gearbox to provide linear motion and drive an actuator output shaft against the drive assembly, whereby when the actuator is energized the linear motion of the actuator output shaft moves the hook arms between an open and a closed position.
