In an automobile tow truck, the towing bed of the present invention includes a concave floor having a radius of curvature of 50 feet. Channel beam segments are welded to the lateral edges of the concave floor. The lower flange of the beam segments terminates slightly beyond the mid-line of the concave floor. The central web of the beam segments spans between the beam flanges, but is trimmed to match the curvature of the curved floor beyond the point of termination of the lower flange. A vertical plate is welded at the front edges of the concave floor and the channel beam segments. A triangular plate is welded at each side of the towing bed to the upper flange of the channel beam segments, the vertical plate and the concave floor. An additional section of metal plate is welded to the underside of the concave floor at the rear approach edge of the towing bed to add strength and durability. Rails coextensive with the towing bed are affixed to the surface of the bed in spaced relation to opposite ones of the channel beam segments.
