A rear loading trailer includes a rearward end lowering mechanism to eliminate or reduce unnecessary weighting of the rear wheels and axle during loading or unloading of heavy equipment such as mining earth movers, shovels and the like. The lowering mechanism lowers the rearward end of the trailer and a ramp associated therewith onto a ground surface. With the ramp and trailer end supported at grade, the trailer body and the ground support the weight of the equipment during initial loading/unloading rather than the axles and/or wheels, thereby avoiding possible damage to the wheels and axles. The ramp moves with the trailer end so that trailer lowering would cause the ramp to also lower to the ground.
