Hendrickson Auxiliary Axle Systems has released the Composilite RO lift axle, designed specifically for Class 8 roll-off vehicles.

The 13,500-lb. RO fixed axle fits flat to the frame for maximum clearance from cylinder beams, attachments and sliding components, the company said.

According to Hendrickson, beams are spaced inboard one inch for additional clearance, and the spring plates mount to the inside of the frame rail while the parallelogram design ensures proper wheel tracking and helps enhance tire life.
