20090115154 | Independent Adjustable Axle Suspension System - An independent adjustable axle suspension system for mounting a wheel to a frame of a trailer for transport of the trailer over a support surface. The axle suspension system includes a tower adapted to be attached to the frame and an axle unit adapted to receive the wheel. The tower is selectively moveable with respect to the axle unit along guide assemblies between extended and retracted positions to thereby selectively position the height of the frame with respect to the support surface. | 05-07-2009 |
