CATERPILLAR CB634 STATIC SMOOTH DRUM ROLLER

Technical Description

The Caterpillar CB634 Static Smooth Drum Roller is a heavy-duty compaction machine designed for efficient soil and asphalt surface preparation. It features an 84-inch wide smooth steel drum with a diameter of 51.2 inches, providing a static linear load of 426.8 lb/in for effective compaction. The drum vibrates at a frequency of 2520 vibrations per minute (44 Hz), with multiple nominal amplitudes of 0.1 inches, generating centrifugal forces ranging from 19,108.8 lb to 31,023.7 lb, adapting to different compaction requirements. Powered by a Caterpillar 2236 engine model 3116T, it delivers a gross power of 144.9 hp and net power of 138.2 hp, with a displacement of 402.8 cubic inches and turbocharged design. The machine’s operating weight is approximately 28,219 lbs, enabling strong ground-contact pressure. It operates at a maximum speed of 7.6 mph with a hydraulic system fluid capacity of 15.9 gallons and a fuel tank capacity of 66.1 gallons. The CB634’s dimensions measure 16.25 feet in length, 7.59 feet in width, and 10.22 feet in height to the top of the cab, with an inside turning radius of 170 inches, allowing for maneuverability in confined sites. Equipped with a hydraulic drive, 12V electrical system with a 105 amp alternator, and cooling fluids totaling 8.2 gallons, it is built for durability and reliability in demanding construction environments. This model provides versatile operation suitable for thick lifts and various asphalt mixes, making it a robust solution for seamless surface compaction.
