The ultimate in spreading power for heavy trucks with 72"- 120" cab-to-axle. Highway departments and large contractors can choose from 4.5 to 15 yard capacity. A screw-jack gives precision control of the feed gate, and adjustable baffles let you vary the spread pattern. Parts subject to the greatest wear are built tough for longer life, and are designed to be replaceable to extend the life of the sander. All sizes are available in carbon steel (painted highway orange) or Type 304 stainless.
