  • Movable tipping frame for hoist trucks
    Patent number: 4889464
    Abstract: A hoist vehicle of the semi-trailer type has a slide frame on which a tipping frame is pivotably mounted. The slide frame is adjustably movable between forward and rearward positions relative to the bed of the vehicle to locate the load carried by the tipping frame at positions where the weight bearing on the axles of the vehicle is optimized so that greater payloads may be carried without exceeding government imposed maximum axle loadings. A chain is trained about sprockets and connected to the slide frame to accurately adjust the position of the slide frame and the center of gravity of the payload.
