Abstract

Abstract Flat bed transporting vehicle for containers, farm and road machinery and other vehicles and lading, having a series of anchor channels extending along the vehicle for the length of the vehicle and unitized with the frame structure of the vehicle to form a unitary part of the chassis frame supporting beams, in which couplers for containers or tie-downs for anchor chains or tie-downs winches may be locked in a selected position in the channels and stored in the channels when not in use. Where the vehicle is used for transporting containers, the couplers are positionable above the level of the channels and bed of the vehicle, to couple adjacent ends of containers to the bed of the vehicle, and are locked in extended positions by retaining sockets at the corners of the containers and are released to be retracted beneath the tops of the channels for storage or adjustment along the channels upon removal of the containers from the couplers.
