VOLVO DD22 STATIC SMOOTH DRUM ROLLER

Technical Description

The Volvo DD22 is a static smooth drum roller engineered for efficient compaction tasks. It features a compact overall width of 3.9 ft (1.0 m) and an inside turning radius of 12.6 ft (4 m), providing excellent maneuverability on job sites. The roller is equipped with front and rear drums each measuring 47.2 inches (1,200 mm) in width and 27.56 inches (700 mm) in diameter. Its vibratory system operates at frequencies of 3,300 to 4,000 vibrations per minute (55 to 67 Hz) with an amplitude of 0.021 inches (0.53 mm), delivering a high centrifugal force of 8,318 lb (37 kN) for effective soil compaction. The DD22 is powered by a reliable Cummins A1700 diesel engine, providing 32 horsepower (24 kW). The engine supports consistent operation with a transport length of 95 inches (2,420 mm) and a maximum travel speed of 6.2 mph (10 km/h). The machine’s operating weight totals 5,400 lb (2,450 kg), evenly distributed with 2,700 lb (1,225 kg) over each drum, ensuring optimal ground contact and stability. Overall height to the top of the rollover protective structure (ROPS) is 103.3 inches (2,624 mm), aligning with safety standards. This roller’s combination of precise dimensions, robust engine performance, and vibratory compaction force make it suitable for various infrastructure and roadwork projects requiring smooth and uniform soil compaction.
