Abstract
The self-loading tilt bed trailer has an elongated tiltable bed normally disposed in a substantially horizontal road traveling position that may be tilted about a transverse horizontal axis to a downwardly and rearwardly inclined position. The bed is pivotally coupled at its front end to a towing tractor for pivotal movement of the bed about a substantially vertical axis. When the bed is tilted steeply enough to raise the wheels completely off the ground so the weight of the bed is supported only by a ground-engaging pad at the rear of the bed and the tractor at the front, actuation of a hydraulic cylinder associated with the pad causes the rear of the bed to be shifted a short distance to the right or left relative to the stationary pad, pivoting about the upright hitch axis at the tractor. The bed-supporting undercarriage of the trailer may be moved from a rearward, road traveling position to a forward tilt position for decreasing the slope angle necessary to bring the rear end of the bed into engagement with the ground.
