ABSTRACT:
The present invention provides a non-articulating low load platform trailer longitudinally divided into three load carrying segments; a rear load platform, a front coupling platform, and an inclined transitional platform between the coupling platform and the load platform. The trailer of the invention includes a self-contained power actuated lifting mechanism for the purpose of lowering the nose of the trailer to the ground without articulation of the trailer body to facilitate loading and unloading, and for the purpose of raising the nose of the trailer from the ground. The lifting mechanism includes lever arms configured to increase the vertical component of lifting force exerted by lift actuators, and further includes leverage links disposed between the lift actuators and lever arms for the purpose of further increasing the vertical component of lifting force when the nose of the trailer is near the ground.
