Abstract
A tow dolly lift having a tubular member that is connected to a hydraulic system configured to lift a vehicle. The tubular member includes an extendable arm and a platform body, the hydraulic system includes a pair of hydraulic lifting pistons and a power source, and the tubular member is operably connected to the hydraulic system. In operation, the tubular member raises the vehicle upwardly and extends outwardly from the tow dolly to lower and extend under the vehicle. The tubular member then lifts the vehicle upward onto the tow dolly under hydraulic power. In this way, the tow dolly lift automatically secures the vehicle to the tow dolly. The tow dolly lift is assembled into a tow dolly lift or be a standalone unassembled tow dolly lift kit sold as an aftermarket item.
