ABSTRACT:
Apparatus for coupling a tug boat to a barge having a notch in its stern. Coupling units mounted on the opposite sides of the tug have extensible and retractable rams which carry toothed heads into and out of toothed channels on the opposite sides of the stern notch. Each ram is extended and retracted by an actuator screw driven by low and high speed electric motors. A lock nut can be tightened on the screw to prevent it from rotating relative to the ram. The rams are controlled from a control panel located in the wheel house of the tug.
