CATERPILLAR CB32B STATIC SMOOTH DRUM ROLLER

Technical Description

The Caterpillar CB32B is a compact, versatile smooth drum roller designed for small to medium-sized compaction projects. It features 28-inch diameter, 51-inch wide tandem vibratory drums, delivering excellent compaction with a maximum centrifugal force of 7,823 lbs per drum. The vibratory system offers three frequency settings (42, 52, and 63 vibrations per minute) and a high nominal amplitude of 0.1 inches, providing adjustable compaction intensity and sound control. Powered by a Cat C1.5 engine producing 36.2 hp (27 kW), it achieves a top travel speed of 7.5 mph. The roller’s operating weight is approximately 6,190 lbs, with a static linear load of 69 lbs per inch, optimizing soil density and surface finish. The machine’s dimensions include an overall length of 8.5 ft, width of 4.7 ft, and height up to 106 inches, with a tight turning radius of 93 inches inside the drum edge for enhanced maneuverability. A 17-gallon fuel tank supports extended operation, complemented by a 62-gallon water spray system with triple filtration to maintain effective dust suppression and ease of maintenance. Additional features include a 50 mm (2-inch) drum offset for improved edging and curb control, an intuitive multifunction control panel with LED indicators, and an automatic vibration shut-off when the propel lever is neutral. The CB32B’s design balances productivity and ease of use, making it ideal for applications such as small parking lots, lane additions, and shoulder work, delivering efficient, consistent compaction results at lower operating costs with reduced maintenance intervals.
