HAMM H7I VIO STATIC SMOOTH DRUM ROLLER

Technical Description

The HAMM H7i VIO is a vibratory smooth drum roller designed for efficient soil and asphalt compaction. It features a smooth front drum measuring 66.2 inches wide and 47.5 inches in diameter with a 0.8-inch thickness, delivering a high centrifugal force of 27,651.5 lbs at 36 vibrations per minute (vpm) for superior compaction performance. The machine is powered by a 4-cylinder Kubota V3307-CR-T diesel engine rated at 73.3 hp (54 kW) at 2200 rpm, compliant with EU Stage IIIB / EPA Tier 4 emissions standards and equipped with DOC-DPF exhaust gas recirculation. The H7i VIO has a maximum operating weight up to 15,057.6 lbs, with front and rear axle loads of approximately 8,300 and 5,644 lbs, respectively. Its articulated steering system includes a 10-degree oscillating angle, enabling enhanced maneuverability, supported by a tight turning radius of 10.9 ft. Dimensions include an overall length of 173.6 inches, a cab height of 9.6 ft, ground clearance of 12.5 inches, and a width over the cab of 72.6 inches. The roller offers a maximum transport speed of 12 mph and a working speed of 6 mph. Additional features include a high static linear load of 125.5 pounds/inch, tangential amplitude of 5.4 inches, and safe operating slopes of 38 degrees front and 42 degrees rear. Fuel capacity stands at 32.5 gallons, supporting long operation cycles for heavy-duty compaction tasks in construction and earthworks.
