Abstract
A combination tilting bed carrier and attached wheel-lift apparatus mounted on a chassis of a towing vehicle. The bed carrier includes a first pivot connected to the chassis and a first motive element extending between the chassis and the bed carrier for actuating tilting of the bed carrier about the first pivot. A wheel-lift is positioned below the bed carrier and includes a second pivot for pivotally connecting the wheel-lift to the chassis, with the first pivot and the second pivot concentrically, or substantially concentrically, aligned with each other. A second motive element extends between the wheel-lift and the bed carrier for actuating tilting of the wheel-lift about the second pivot. The second pivot may include a third motive element which may adjust the second pivot point, and which in conjunction with the second motive element, allows the wheel-lift to conform with either a positive or negative ground surface. The second motive element has a control element to maintain the wheel-lift in a predetermined position in the event of a failure of a second motive element. A third pivot is positioned on the chassis for pivotally connecting a stabilizer strut arm between the whe…
