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 1 in. 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.
