Abstract
A lift assembly for a suspension assembly of an axle/suspension system is located generally adjacent to and beside the suspension assembly. The lift assembly includes an air chamber, a support member assembly, a pivot arm assembly and a beam support assembly. The support member assembly attaches to the hanger of the suspension assembly, to the air chamber, and pivotally attaches to the pivot arm assembly. The air chamber also attaches to the pivot arm assembly. The pivot arm assembly pivotally attaches to the beam support assembly which in turn attaches to the beam of the suspension assembly, for raising and/or lowering the suspension assembly during operation of the heavy-duty vehicle.
