ABSTRACT:
A flat bed vehicle has a king pin mounted in the flat bed for connection to a trailer to create a fifth wheel tractor-trailer combination. The king pin is vertically reciprocated above the flat bed and below the flat bed by a hand crank located at an outside edge of the flat bed. The king pin is held in its upward position by means of a horizontal bolt passing through a hole in the king pin. The bolt is manually removed from the king pin, for lowering the king pin, by a manual pull rod extending to the exterior of the vehicle bed, preferably adjacent to the hand crank.
