The present invention is a controllable hook assembly having an actuator connected by a clutch to a drive assembly configured to limit the connection to a predetermined linear force applied to the actuator. The drive assembly and actuator of the controllable hook assembly also 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 is configured to operate the drive assembly to move gear teeth in the hook arms cooperating with screw threads in said actuator to provide rotation about a pivot point, drive an actuator output shaft such that when the actuator is energized the linear motion of the actuator output shaft moves the hook arms between an open and a closed position so as to allow for repeated capture of loads by helicopter or other lifting devices without the need for extensive setup for such load capture.
