ABSTRACT:
A hydraulically operated tailgate associated with a low bed, semi-trailer vehicle has a pivoted extension that is displaceable between an extended position coplanar with the ramp surface of the tailgate and a bumper position transverse to and underlying the ramp surface. A hydraulic actuating mechanism displacing the extension to the bumper position, simultaneously locks the tailgate mechanically to the frame of the semi-trailer vehicle.
