    Abstract: A towable trailer has a main frame and an inner frame, and a scissors-type lift structure between them so as to elevate the inner frame above the main frame. A first hydraulic cylinder is used to actuate the scissor-type lift in order to raise the inner frame. A second hydraulic cylinder is also preferably provided in order to raise the front end of the inner frame, so as to provide a towable trailer having a tiltable and raisable platform which can be more easily loaded and unloaded.
