VOLVO DD138HA STATIC SMOOTH DRUM ROLLER

Technical Description

The Volvo DD138HA is a heavy-duty static smooth drum roller designed for efficient soil compaction in construction and roadwork applications. It features an 84-inch wide drum with a diameter of 55.2 inches, delivering a high vibration frequency of 2700 vibrations per minute (45 Hz) to maximize compaction effectiveness. The roller is powered by a Cummins engine producing 173 horsepower, supporting an operating width of 92 inches and an overall length of 19.67 feet. Its robust design includes a wheelbase of 11.65 feet, ground clearance of 20.08 inches, and a height to the top of the cab at 10.44 feet, allowing it to operate effectively on varied terrain. The machine's operating weight is approximately 28,726 pounds, ensuring strong ground contact for superior compaction results. Fuel and hydraulic capacities are 68.5 gallons and 36.5 gallons respectively, supporting extended operation. Its centrifugal force ranges from 16,703 pounds at low amplitude to 41,702 pounds at high amplitude, enabling variable compaction intensities. The nominal amplitude is maintained at 0.1 inches for both high and low settings, optimizing soil consolidation without excessive displacement. The roller achieves a maximum speed of 6.6 mph. Electrical systems operate on 12 volts with a 95-amp alternator, providing reliable power for onboard electronics. The inside turning radius measures 179.6 inches, facilitating maneuverability in confined job sites. Overall, the Volvo DD138HA is engineered for high productivity and reliability in demanding compaction tasks.
