VOLVO DD138HFA STATIC SMOOTH DRUM ROLLER

The Volvo DD138HFA is a heavy-duty static smooth drum roller designed for efficient compaction in road construction and earthwork projects. It features an overall width of 4.1 ft and an 84-inch wide drum with a diameter of 55.1 inches, optimizing ground coverage and compaction quality. Powered by a turbocharged Cummins engine delivering 173 hp, the machine operates at a net power output suitable for demanding tasks. It offers a centrifugal force ranging from 36,685 lb (low) to 41,720 lb (high), with a vibration frequency adjustable between 2,700 and 4,000 vibrations per minute, allowing it to adapt to varying soil and asphalt conditions. The nominal vibration amplitude in the low setting is 0.014 inches (0.35 mm), enhancing controlled compaction. The DD138HFA has an operating weight of 30,325 lb, ensuring stability during operation, and a maximum speed of 6.6 mph for maneuverability. It features a fuel capacity of 68.5 gallons and a hydraulic system fluid capacity of 36.5 gallons, supporting extended operational periods. The compactor includes SMART drum technology with eight amplitude settings that automatically adjust frequency and amplitude for optimal compaction on different lift thicknesses. Additional advanced features include a SMART propulsion system for optimal drum impact spacing, a dual water spray system to minimize drum marking and maintain smooth surfaces, and chamfered drum edges to reduce surface damage. The inside turning radius is 15 ft, facilitating tight turns on job sites. These technical specifications make the Volvo DD138HFA a versatile and reliable roller for precise and efficient compaction tasks.
