ABSTRACT OF THE DISCLOSURE A trailer having a variable configuration for carrying heavy loads, including: a main frame, a main suspension system supporting the rear of the main frame, coupling means for coupling the main frame to a power unit with or without an auxiliary trailer and for supporting the front of the frame. Means for coupling on a variety of auxiliary frames are provided, for the purpose of distributing the weight of the payload and the weight of the trailer itself according to legal requirements and requirements of safety. The means generally include a front suspension arm joining the main suspension to the auxiliary frame, a main pivot between the main frame and the auxiliary frame, and an additional connecting link between main and auxiliary frames. In a configuration in which the auxiliary axles are located relatively far from the main suspension, the axles are carried on a secondary frame and joined to the main frame by a booster frame which includes a pivoting or self-steering mechanism to limit excessive scuffing of the tires on the booster frame. An equalizing trailer system is disclosed which is easily dismantled for the removal of unneeded booster axles and the shortening of the trailer when relatively light loads are carried. With booster axles removed the equalizing trailer of the present invention continues to distribute the load among the remaining axles.
