Caterpillar CB22 tandem vibratory rollerCaterpillar says its CB22, CB24, CC24 and CB32 Vibratory Utility Compactors with a dual-frequency vibratory system with single amplitude perform well on asphalt, soil, or base materials. The CB22 has 39-inch-wide drums, and the compact CB24 has one 47-inch drum. The CB32, with a 51-inch drum, offers more coverage in a similar-sized package to the CB24. Apart from the wider drum, the CB32 is similar in size making it easier to transport and maneuver than the larger Cat CB34 utility compactor. The CC24 utility compactor combines a 47-inch-wide vibrating drum and four pneumatic tires for a smooth, tight mat finish. All are powered by the new Cat C1.5 diesel, which is U.S. EPA Tier 4a certified and provides 33 horsepower at 2,800 rpm. Fuel capacity has been increased 17 percent over the previous version.
