LIFT AXLE FOR ROLL-OFFS

Hendrickson Auxiliary Axle Systems has unveiled a new lift-axle model specifically for class 8 roll-off vehicles – the Composilite RO.

With 13,500-lb capacity, the 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.

Hendrickson positioned 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 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 axle delivers 13 in. of travel and 10 in. of lift and weighs in at 905 lb.
