Hendrickson Auxiliary Axle Systems recently unveiled a new lift axle model specifically for Class 8 roll-off vehicles, Composilite RO.

The latest addition to the popular Composilite family, the 13,500-lb. capacity RO fixed axle model fits flat to the frame for maximum clearance from cylinder beams, attachments and sliding components. Scalloped hangers aid in the clearance around roll-off cylinders, the maker said.

Hendrickson positioned Composilite RO springs and parallelogram components inside the frame rails retaining a compact 23.5-in. packing space.

Beams are spaced inboard one-inch for additional clearance, and unique air spring plates mount to the inside of the frame rail.

The parallelogram design keeps lift axle beams parallel to ensure proper wheel tracking and help enhance tire life, and lift plates remain parallel to extend air spring life. The stabilizer features a cover to protect the stabilizing rod from dirt and debris throughout travel.

The new fixed axle delivers 13 in. of travel and 10 in. of lift and weighs in at 905 lbs., the company said
