ABSTRACT:
A transport locking system for a movable-deck trailer includes a telescoping sleeve which is positioned in parallel with a main deck piston and cylinder unit beneath the trailer deck. The main cylinder and the telescoping sleeve are placed in a neutral position when the deck is in the transport position, extended to raise the deck to a dock high position, and retracted to lower the deck to a ramp position. A locking bar is pivotably mounted atop the telescoping sleeve and the locking bar is controlled by a locking piston and cylinder unit to selectively engage or disengage a recess in the sleeve to thereby lock or unlock the sleeve, and thus constrain the deck to the transport position. A switching and control system is provided to coordinate the control of the main deck piston and cylinder unit with the control of the locking piston and cylinder unit.
