Abstract: A hydraulic tilt frame trailer is shown having a main support frame which is tiltable between a generally horizontal position and a rearwardly inclined position for loading and unloading a freight container. The tilt frame is connected to the main support frame by a first pivot point and has an opposite extent which is connectable to a hauling vehicle at a ball connection which forms a second pivot point. The main frame and tilt frame are hydraulically actuated for tilting the main support frame at an upwardly inclined angle and for simultaneously tilting the tilt frame at an opposite, upwardly inclined angle, whereby the main support frame is tilted to the rearwardly inclined position for loading an unloading a container.
