CATERPILLAR CB64 STATIC SMOOTH DRUM ROLLER

Technical Description

The Caterpillar CB64 is a heavy-duty tandem vibratory smooth drum roller designed for asphalt compaction with a standard operating weight around 28,600 lbs (12,980 kg). It features dual 51-inch diameter smooth steel drums, each 84 inches wide, providing a nominal compaction width of 84 inches and an operating width of 92 inches. The machine delivers a high centrifugal force of up to 31,100 lbs per drum at frequencies ranging from 2,520 to 3,800 vibrations per minute, with a nominal amplitude of 0.1 inches, optimizing compaction efficiency across variable soil and asphalt layers. Powering the CB64 is a Caterpillar C4.4 ACERT turbocharged aftercooled diesel engine generating 137 hp gross (approximately 130 hp net), compliant with Tier 3 and Tier 4 final emission standards, ensuring both performance and environmental compliance. The engine features a displacement of 4.4 liters, direct injection, and advanced electronic fuel management for fuel efficiency and durability. The roller has a maximum travel speed of 8 mph and a turning radius inside drum edge of about 155 inches, offering good maneuverability in confined spaces. Dimensions include an overall length of 194 inches, width of 7.7 feet, height to the top of the cab of 10.1 feet, and ground clearance near 8.5 inches. It carries a 50-gallon fuel tank and a 290-gallon water spray tank to maintain optimal drum surface moisture preventing asphalt adhesion. The static linear load at the drum is rated at 170 lbs per inch, delivering consistent smooth compaction suitable for large paving projects and roadway construction. Its robust vibratory system, advanced engine, and durable design make the CB64 a reliable machine for high-quality asphalt compaction.
