CATERPILLAR CB434D STATIC SMOOTH DRUM ROLLER

Technical Description

The Caterpillar CB434D is a robust static smooth drum roller designed for efficient soil and asphalt compaction. It features dual smooth drums with a diameter of approximately 42–43.4 inches and a drum width of 59 inches, providing a standard compaction width ideal for paving projects. The machine delivers a high centrifugal force up to about 17,550 lbs, supporting precise vibratory compaction with vibration frequencies ranging between 53 to 70 vibrations per minute and a nominal amplitude consistently at 0.1 inches. Powered by a Caterpillar 3054C engine with a displacement of 268.6 cubic inches, it produces a gross power output of 83 hp (79.2 hp net), ensuring reliable performance. The CB434D operates at a maximum travel speed of 7.3 mph and weighs approximately 16,689 lbs, offering good balance between power and maneuverability. Its frame provides a ±40° steering angle and ±4° oscillation for smooth travel and uniform drum loading, enhancing operator comfort and reducing maintenance needs. Operational features include a fuel capacity near 35 gallons, hydraulic fluid capacity of 13.3 gallons, and a water spray tank capacity of 211 gallons for drum cleaning. Overall dimensions include an overall length of 165 inches, width of 5.5 feet, and height up to 10.1 feet to the cab top. The CB434D supports an 80-amp alternator and standard 12-volt electrical system, well suited for heavy-duty compaction tasks in road construction and infrastructure projects.
