A safety vehicle lift having a base, a lifting assembly, a drive mechanism, a handle, and a ramp. The base is made of flat rigid construction which may be in one or two sections and may be of solid or grated construction. When in two sections, the sections may be permanently abutted with a hinge or may be temporarily abutted with conventional locking mechanisms. The base contains retractable wheels. The base is wider than the structures supported by the base. A drive mechanism is made up of a jackscrew passing through a threaded cross brace. When the jackscrew is turned manually or mechanically, there is a raising or lowering of the support platform. The lift is provided with a ramp having side walls and leading from the level of the base to the level of the support base. The ramp may be of solid or grated construction. The lift has less weight and equivalent strength compared to prior lifts, thus improving mobility. As the base is grated, the lift may be used on a wide variety of surfaces. The retractable wheels add mobility while maintaining safety. As the base is wider than the lifting mechanism and the ramp, greater stability is maintained.
