INGERSOLL RAND DD31HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Ingersoll Rand DD31HF is a vibratory smooth drum roller designed for compaction tasks in construction applications. It features a robust Kubota V2203M vertical, water-cooled, 4-cycle diesel engine delivering 44 hp (33 kW) for reliable power and performance. The roller’s compact dimensions include a height to the top of the cab of 8.3 ft, an overall length of 8.4 ft, and a width of 4.5 ft, with a wheelbase of 5.7 ft, ensuring maneuverability on-site. The drum has a diameter of 29 inches and a working width of 49.3 inches, generating a medium centrifugal force of 8,093 lbs to effectively compact soil or asphalt. Vibratory performance includes a nominal amplitude of 0.1 inches and a vibration frequency of 70 vibrations per minute, which enhances soil compaction uniformity and depth. The hydraulic system holds 22.4 gallons of fluid capacity, supporting smooth drum and steering operation. Fuel capacity is 18 gallons, allowing extended operation between refills. The machine operates at a maximum speed of 6.3 mph (10 kph) and runs on a 12-volt electrical system with a 40-amp alternator supply. With an operating weight of approximately 6,840 lbs, the DD31HF provides adequate ground pressure to achieve efficient compaction while maintaining operator safety and comfort through an ergonomic cab design. This model suits various infrastructure, roadwork, and general compaction projects requiring a versatile, durable, and compact roller.
