ABSTRACT:
An apparatus includes a tongue, a pivotable beam linked to the tongue, a cylinder configured to move the pivotable beam from an operating position to a transport position, which is narrower than the operating position, and a latchable member connected to the pivotable beam. A locking assembly includes first and second dogs which can receive the latchable member. The second dog can move relative to the first dog from an open position to a closed position in response to movement of the latchable member such that movement of the latchable member out of the second dog opening is blocked by the first dog while the second dog is in the closed position. The apparatus includes a locking member that moves in response to movement of the cylinder from an unlocked to a locked position to lock the dogs in the closed position.
