Abstract
Abstract A subframe structure for a tilting bed vehicle carrier. The subframe structure has an attached wheel lift and the subframe is pivotally mounted on the chassis of a towing vehicle. The subframe structure includes pivotally mounted strut members for load distribution within the subframe. The load which is distributed by the strut members tends to counteract the bending and torsion forces imposed upon the subframe structure by the towed vehicle on the rear wheel lift.
