7' Width for Truck Actuated Dock Levelers increases the standars 6' width. Truck Actuated Dock levelers are the Fully Automatic Loading Ramp, so no dock attendant needed. This docklever unit comes with legs for in front of dock placement. The truck backs against twin actuating arms (bumpers) pushing carriage back (dock and trailer door must be raised). As carriage goes back, deck goes up. When the carriage bumpers contact dock, the deck floats down to rest on trailer. When truck pulls out, deck returns to level supported position automatically.
