VOLVO DD28HF ULTRA-PAC STATIC SMOOTH DRUM ROLLER

Technical Description

The Volvo DD28HF Ultra-Pac is a robust static smooth drum roller designed for efficient soil compaction. It features a 49.2-inch wide, 28.9-inch diameter drum with a vibration frequency of 4200 vibrations per minute (70 Hz), producing a maximum centrifugal force of approximately 8,206 lbs for optimal compaction performance. The roller is powered by a Kubota V2203M, a four-cylinder, vertical, water-cooled diesel engine delivering 44 hp, known for reliable industrial use and low emissions due to its advanced combustion technology. The DD28HF offers an operating width of 53.7 inches and an outside turning radius of 151.5 inches, providing excellent maneuverability. It measures 8.42 feet in length, 4.48 feet in width, and 8.3 feet in height to the top of the cab with a wheelbase of 5.66 feet and ground clearance of 19 inches. The operating weight is about 6,751 lbs, with 3,130 lbs static weight on the front drum. Fuel capacity is 18 gallons, and water tank capacity for drum wetting is 79 gallons to prevent asphalt sticking during compaction. It has a maximum speed of 6.3 mph and hydraulic fluid capacity of approximately 22.5 gallons. Electrical systems operate at 12 volts with a 40-amp alternator. The drum shell thickness is 0.55 inches, designed for durability in road construction and maintenance tasks requiring smooth surface finishes. Side clearance is 2.2 inches, and curb clearance is 19 inches, allowing safe operation in various site conditions. This model is ideal for medium-duty compaction projects requiring smooth drum performance and reliable power.
