The invention discloses a trailer chassis. The trailer chassis is characterized by comprising that a pulling hitch pole is installed on the front portion of a rack, a front guiding support device is movably installed on the pulling hitch pole, a pulling connection device is installed on the front portion of the pulling hitch pole, a travelling system is used for driving the rack to move, and a braking system can achieve automatic reversing without using an air source and a hydraulic source, wherein upper support devices are arranged on the left side and the right side of the rear portion of the rack respectively. The trailer chassis has the advantages that manual short distance movement can be achieved, pulling by a motor tractor can be achieved, being carried by a pallet carrier can be achieved, transporting by a helicopter can be achieved; road transportation, waterway transportation, railway transportation and air transportation are better achieved, the maneuvering flexibility is high; by the three installed support devices, when the trailer is in use, the trailer body can be balanced and stabilized, meanwhile, the load of the traveling system can be reduced effectively; by installing the brake system without using the air source and the hydraulic source, automatic reversing can be achieved; and the vibration reducing performance is good.
