Abstract
A tilt bed for a truck or a trailer, the tilt bed being able of carrying loads and providing its own ramp. The tilt bed comprises a frame, and a deck mounted on and supported by the frame, the deck having a front portion and a rear portion. The deck has rollers connected to the front portion, and the frame has tracks mounted at an angle, the tracks for guiding the deck rollers. The trailer bed further comprises a hydraulic cylinder that has a first end connected to the frame and a second end connected to the trailer bed. The hydraulic cylinder has a piston and a cylinder. As the piston moves from an extended state into a retracted state, it causes the trailer bed to move in a rearward position. At the same time, the tracks force the deck rollers in an upward motion and cause the trailer bed to tilt. Finally, the hydraulic cylinder remains parallel to the trailer deck at all times. This orientation is accomplished because the trailer deck and the hydraulic cylinder tilt around a common axis.
