CATERPILLAR CB634D STATIC SMOOTH DRUM ROLLER

The Caterpillar CB634D is a robust static smooth drum roller designed for heavy-duty compaction tasks. It features an 84-inch wide, 51.2-inch diameter smooth drum delivering a maximum centrifugal force of 35,744.7 lbs, with five selectable vibration amplitudes and frequencies up to 2,640 vibrations per minute to optimize compaction on various asphalt and granular materials. The drum’s nominal amplitude remains consistent at 0.1 inches across all vibration settings, providing precise compaction control. Powered by a turbocharged Caterpillar 3116T engine with a displacement of 402.8 cu in, the machine produces a gross power of 144.9 hp and a net power of 138.2 hp, enabling efficient operation with a max speed of 7.6 mph. The roller’s operating weight is approximately 28,219 lbs, with an operating width of 91 inches and an overall length of 16.3 ft, allowing it to handle large compaction areas effectively. Its turning radius of 170 inches and wheelbase of 10.4 ft provide maneuverability in confined areas. The machine includes a 66.1-gallon fuel capacity, 8.2 gallons of cooling system fluid, 4.5 gallons of engine oil, and a 15.9-gallon hydraulic system fluid capacity to support long operational cycles. Operating on a 12-volt electrical system with a 105-amp alternator, the CB634D ensures reliable performance. Its static linear load is 426.8 pounds per inch, making it versatile for intermediate to thick lift applications in road construction and asphalt compaction projects.
