ABSTRACT:
A cargo loading system which includes a spreader bar and overheight attachment wherein the overheight attachment incorporates an automatic latching mechanism for the purpose of locking and unlocking engagement of the spreader bar. The automatic latching mechanism is actuated by the twistlocks of the spreader bar and serves to obviate the need for dock-side personnel and the attendant harzardous working conditions posed to these personnel by conventional mounting pin attachment of the spreader bar and overheight attachment.
