Hendrickson Auxiliary Axle Systems recently unveiled a new lift axle model specifically for Class 8 roll-off vehicles – COMPOSILITE RO.
According to Hendrickson…
The latest addition to the popular COMPOSILITE family, 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.
Hendrickson positioned COMPOSILITE RO springs and parallelogram components inside the frame rails retaining a compact 23.5-inch 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.
COMPOSILITE RO fixed axle delivers 13 inches of travel and 10 inches of lift and weighs in at 905 pounds.
