Hendrickson Auxiliary Axle Systems' COMPOSILITE RO lift axle model is specifically designed to deliver 13 inches of travel and 10 inches of lift for Class 8 roll-off vehicles.

The 13,500-pound 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 RO's springs and parallelogram components are positioned inside the frame rails for a 23.5-inch packing space. Beams are spaced inboard 1-inch for additional clearance, and 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 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.
