Patent

CA 2569584

A ramp member is pivotally supported at the rear of a flat bed trailer for pivotal movement between a loading position extending from the flat bed to the ground and a storage position supported on the trailer bed, through an intermediate position between the loading position and the storage position. First and second torsion members are arranged such that at least one of the torsion members biases the ramp member from each of the loading and storage positions towards the intermediate position. The torsion members permit substantially a full weight of the ramp member to be counter-balanced through its full range of motion so that a single ramp member spanning a full width of a rear end of the trailer in the lateral direction can be manually displaced by a single operator.
