Abstract
A device and method is claimed for elevating a vehicle. The jack device has a frame with a first section and a second section that are joined together at a hinged connection. The first section and second section of the frame are supported by wheels. A spool is coupled to at least one of the wheels. A flexible element extends from the spool to an opposite point on the frame that is across the hinged connection. The flexible element winds around the spool and pulls the first section and the second section together while being wound. A support platform is carried by the frame and is elevated as the first section of the frame and the second section of the frame move toward each other.
