ABSTRACT:
A towing dolly has a pair of supports between which a pair of wheels of a disabled vehicle may be cradled, the supports being carried by rails on which respective pairs of rocker arms are pivotally mounted. Each rocker arm carries a dolly support wheel and a mounting adapted to that a hydraulic jack may be positioned between the pair of rocker arms of each rail. Upon actuation of the hydraulic jack the rails and thus the wheel engaging supports are raised relative to the axles of the dolly wheels, thereby raising the wheels of a disabled vehicle cradled on the supports. A locking device is carried by each rocker arm for cooperating with a respective hold-down block on the rails after the rocker arm has been pivoted by actuation of the hydraulic jack so that the hydraulic jack may be removed while the disabled vehicle is towed.
