ABSTRACT:
A heavy duty tractor drawn lift deck trailer for transporting load holding pallet frame units each having a ground engaging support structure enabling it to be picked up for transport or dropped off for storage without need for additional equipment or personnel. The trailer features an over-center mechanical lock for the lift deck which will be power engaged as the lift deck is elevated into raised transport position and power released as the lift deck is permitted to descend to lowered loading position on the trailer support frame. The lock is connected between a point on the lift deck and a point on one of the trailer hinge panels and remains engaged when the lift deck is tilted for dumping.
