CATERPILLAR CD44B STATIC SMOOTH DRUM ROLLER

Technical Description

The Caterpillar CD44B Static Smooth Drum Roller is a robust compaction machine designed for asphalt and granular material applications. It features a Cat C3.4B ACERT engine delivering 102 hp, compliant with Tier 4 Interim and Stage IIIB emissions standards. The machine offers a tandem smooth drum configuration with a drum width of 59 inches (1500 mm), a drum diameter of approximately 44 inches, and a static linear load of 156 lb/in, ensuring effective compaction performance. It operates with a dual amplitude and dual frequency vibratory system, providing vibration frequencies between 53.3 to 63.3 vpm to adapt to various lift thicknesses and compaction needs. The CD44B has an operating width of 66 inches and an inside turning radius of 114 inches, facilitating maneuverability in confined spaces. Structurally, it measures 13.84 feet in length, 5.5 feet in width, and has a height of 116 inches with ROPS/FOPS. The operating weight ranges from approximately 18,056 to 18,497 lbs depending on cab or ROPS/FOPS configuration, with maximum front and rear drum weights near 9,200 lbs each, providing balanced weight distribution. Additional features include a wheelbase of 10.25 feet, ground clearance of 10 inches, a maximum travel speed of 7.5 mph, and a centrifugal force capacity per drum up to 17,602 lbs for high compaction force. The machine also integrates advanced systems like automatic traction control and a triple-filtered water spray for dust control, enhancing operational efficiency and road quality.
