CATERPILLAR CS56B STATIC SMOOTH DRUM ROLLER

Technical Description

The Caterpillar CS56B is a robust smooth drum vibratory soil compactor designed primarily for granular soil compaction applications. It features an 84-inch wide smooth drum with a diameter of 60.4 inches, delivering maximum centrifugal force of 67,600 lbs at a vibratory frequency of 30.5 Hz (1830 vpm), ensuring effective soil consolidation. The compactor is powered by a Cat C4.4 ACERT engine producing 157 hp (117 kW), paired with a two-speed hydrostatic transmission enabling a maximum travel speed of 7 mph (11.4 kph). Weighing 25,346 lbs with the cab, the CS56B offers excellent stability and compaction force with a static linear load exceeding 166 lb/in. Its ground clearance is 17.4 inches, overall dimensions include a length of 231 inches, width of 7.6 feet, and cab height of 10.3 feet, complemented by a tight inside turning radius of 145 inches for maneuverability in confined spaces. The vibratory system has dual amplitude settings (0.08–0.1 inches nominal amplitude) to optimize compaction depth and force. The machine includes an operator-friendly cab with an adjustable seat, integrated multifunction LCD display, and electronic propel control for precise handling. Fuel capacity is 64 gallons, supporting extended operation. Maintenance is simplified via maintenance-free hitch bearings and extended service intervals. Optional features include padfoot shells for cohesive soils and a leveling blade. The CS56B's reliable design and powerful vibratory system make it well-suited for medium to large-scale roadwork, foundation preparation, and earthwork projects requiring uniform compaction and high productivity.
