CATERPILLAR CB113 STATIC SMOOTH DRUM ROLLER

Technical Description

The Caterpillar CB113 is a compact, static smooth drum roller designed for efficient compaction on small to medium-sized job sites. It features a single offset front drum with a diameter of 22.7 in (575 mm) and a compaction width of 880 mm (34.6 in), providing excellent flush-edge capability for curbs and forms. The machine has an operating weight of 3,307 lb (1,500 kg) and delivers a static linear load of 133.7 lb/in (23.6 kg/cm), ensuring consistent ground pressure for uniform mat density. Vibration is provided on the rear drum with a frequency of 53.3 Hz (3,200 vpm) and a nominal amplitude of 0.1 in (2.5 mm), producing a medium centrifugal force of 2,315.6 lbf (10.3 kN) for effective soil and asphalt compaction. Power is supplied by a Hatz 2G 40H air-cooled, 4-stroke, 2-cylinder diesel engine with 60.9 cu in (1,000 cc) displacement, rated at 19.8 hp (14.7 kW) at 3,000 rpm, meeting EU Stage II emission standards. The CB113 has a maximum travel speed of 5 mph (8 km/h) and a tight turning radius for high maneuverability in confined spaces. Standard features include a corrosion-resistant water spray system, foldable ROPS, and excellent operator visibility. With a ground clearance of 7.7 in (195 mm), overall length of 6.9 ft (2.1 m), and operating width of 37 in (940 mm), the CB113 is ideal for utility work, patching, and small paving projects where agility and precision are critical.
