A hoist for raising and lowering a truck bed to and from a truck frame is provided which utilizes a lever to accomplish initial lift and to further position the hydraulic cylinder at a more efficient angle for completion of the lift process. The hoist further provides a locking device to immobilize the lever and one end of the hydraulic cylinder during certain phases of the raising and lowering cycle, improving safety and stability in the dump bed raising and lowering process.
