Heyl & Patterson Continuous Barge Unloaders (CBU) from HMA Materials Handling are some of the most efficient, rugged and durable in the bulk materials handling business. Many are still in full operation after 40-plus years. The Heyl & Patterson CBU from HMA Materials Handling is designed to unload materials such as coal, lime, limestone, petroleum coke, metal ores, wood chips and grain from barges at free digging rates of up to 5000 tph. Extremely efficient, this CBU from HMA Materials Handling maintains a much higher average offloading rate than other types of barge unloaders, while horsepower requirements are much less than pneumatic systems. Very easy to operate, the CBU does not degrade fragile products and can be installed quickly due to its modular construction.
