A four post automotive lift system is disclosed wherein each post contains a locking mechanism and adjustable lifting points. Each pair of posts has a transverse beam that is secured by the locking mechanisms and supports the weight of the vehicle. Each of the four posts are positioned on the floor and supported by a structure on the outside side of the lifting device. Each pair of posts on ether side of the vehicle is tied together by a supporting structure. The beam supporting the vehicle is lifted at each of the four posts by a simple lifting device and then locked in place on the post by the locking mechanism. The adjustable lifting point can be placed anywhere along the four posts to extend the range of the simple lifting device as the vehicle is lifted to different heights. |
