Abstract A mobile lift, particularly for use with heavy vehicles is provided with first and second rectangular frame members and wheels for journalling the first frame member. The second rectangular frame member is comprised of a parallel linkage system and is pivotly mounted at one end thereof on the first frame member. The other end of the second frame member includes a pair of laterally spaced apart ears that are pivotly secured to a pair of supporting brackets each of which has one surface that is maintained in the horizontsl position at all times. A hydraulic cylinder is pivotly mounted on the first frame and the piston of the cylinder is pivotly mounted to the second frame. A pair of laterally spaced apart telescoping racks are pivotly mounted on the first frame concentrically with the cylinder and a pawl cooperates with each of the racks. Lever means are used for controlling the movement of the pawls in opposition to spring means that normally maintain the pawls in engagement with the racks.
