DYNAPAC CA4000DCO STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA4000DCO is a robust static smooth drum roller engineered for efficient soil compaction in large-scale construction projects. It features a single smooth drum with a width of 83.9 inches (2130 mm) and a diameter of 59.9 inches (1520 mm) with a drum shell thickness of 1.4 inches (35 mm), providing a static linear load of 229.6 pounds per inch. Powered by a water-cooled, turbocharged Cummins QSB4.5 engine producing 159.6 hp (119 kW) at 2200 rpm, the roller delivers high centrifugal force capacity—up to approximately 58,675 lbs in high mode—ensuring effective compaction. Key dimensions include an overall length of 235.9 inches (5990 mm), a wheelbase of 117.8 inches (2990 mm), and a turning radius of 10.9 ft inside and 18.4 ft outside, supporting maneuverability on job sites. The unit’s curb and ground clearance both measure 17.8 inches (450 mm), while its operational height reaches 7 feet with the top of the ROPS/FOPS at 9.5 feet (2880 mm), ensuring operator safety and visibility. The Dynapac CA4000DCO has a fuel capacity of approximately 72 gallons (272 liters) and a top speed of 7.5 mph (12 km/h), suitable for steady compaction workflows. With an operating weight near 30,200 lbs (13,700 kg), it balances mass and mobility for effective soil consolidation on highways, airfields, and large foundation works. The roller rides on 23.1 x 26 AW tires designed for durability and traction on varied terrain grades up to 57%.
