Abstract
A converter dolly replaces the rear wheels of a truck trailer to provide the trailer with a steering ability about its rear wheels. The converter dolly is modified to include a hydraulic actuating system, including a piston, cylinder, and pump assembly, which act upon the tongue of the converter dolly to pivot the converter dolly about a king pin. The actuation of the hydraulic system is performed by the driver of the tractor towing the trailer through a control system mounted in the tractor cab.
