Abstract
A lift assembly for an axle of the trailer of a semi-trailer or of another vehicle such as a straight truck, is mounted generally adjacent to and beneath each suspension beam of the axle/suspension systems of the trailer or other vehicle. The manner of mounting the lift assembly generally adjacent to and beneath the beam provides sufficient clearance for concurrent disposition of a dual service/parking brake chamber adjacent to and beneath the beam. The location and orientation of the axle lift assembly, relative to radial lines emanating from the pivot point of the suspension beam, facilitates the application of efficient lift forces to the beam by the lift assembly, which in turn results in less wear to an air chamber of the lift assembly. The air chamber of the lift assembly can be quickly and easily removed and reinstalled to allow for replacement of the dual brake chamber.
