Abstract
A hydraulic tail trailer comprising a main deck having a main tail assembly pivotally connected to the rearward end thereof with the pivotal connection therebetween being located forwardly of the centerline of the rear axle of the trailer suspension system. The location of the hinge between the main deck and the main tail assembly, by being located forwardly of the centerline of the rear axle, provides a main tail having an increased length thereby providing a lower loading angle without increasing the overall length of the trailer.
