Abstract
A trailerable load-transferring assembly is removably attachable to the rear portion of a load-bearing vehicle. The load-transferring assembly includes a pivot connection, an auxiliary axle, an elongate abutment member that extends between a free end and an abutment end, and an actuator assembly disposed between the free end of the abutment member and the auxiliary axle. When the load-transferring assembly is connected to the vehicle by the pivot connection, the actuator assembly is actuated such that it applies a lifting force on the free end relative to the auxiliary axle. The lifting force causes the abutment member to pivot about the pivot connection, bringing the abutment end of the abutment member into an abutting engagement with an abutment surface attached to the frame of the load-bearing vehicle. The lifting force and abutting engagement prevents transverse movement of the load-transferring assembly relative to the vehicle and transfers a portion of the load from the vehicle's rear axles to the auxiliary axle.
