CATERPILLAR CB68B STATIC SMOOTH DRUM ROLLER

Technical Description

The Caterpillar CB68B Static Smooth Drum Roller is a high-performance compactor designed for efficient asphalt and granular soil compaction. It features an 84-inch (2130 mm) wide smooth drum with a 6-inch offset, enabling a maximum compaction width of 92 inches. Powered by a Cat C4.4 ACERT engine developing 142 hp (106 kW), this model delivers robust performance while maintaining fuel efficiency. The roller's operating weight is approximately 31,162 lb (14,180 kg), providing a static linear load of 184 lb/in, essential for achieving optimal compaction density. The CB68B offers a turning radius inside of 168 inches, overall dimensions of 15.5 ft length, 7.67 ft width, and 10 ft height (with ROPS/FOPS), and a wheelbase of 11.3 ft, providing good maneuverability on jobsites. Its travel speed ranges from 4.5 mph in low gear to a maximum of 8 mph. Equipped with a water spray system holding 264 gallons, it keeps the drum wet to prevent asphalt sticking during paving. Fuel capacity is 66 gallons, supporting extended operation. Vibration settings include two frequencies (42 and 63.3 vpm) with adjustable amplitude down to 0.01 in, enabling versatility for different compaction needs. The roller produces centrifugal forces between 16,950 and 31,069 lb per drum, allowing efficient consolidation of materials. With excellent visibility, smooth steering, and durable design, the CB68B is ideal for large-scale paving projects requiring consistent, high-quality compaction.
