HAMM HD+ 70I VO STATIC SMOOTH DRUM ROLLER

Technical Description

The HAMM HD+ 70i VO is a tandem smooth drum roller engineered for efficient compaction with both a vibrating front drum and an oscillating rear drum, enhancing compaction quality and surface finish. It features a robust DEUTZ TCD 2.9 L4 engine compliant with EPA Tier 4 emissions, delivering 74.3 hp at 2500 rpm. The machine’s operating weight is approximately 21,782 lbs, providing significant ground pressure for effective soil and asphalt compaction. The drums are both smooth and non-split, with a diameter of 44.9 inches, a width of 59.1 inches, and a thickness of 0.7 inches. The front drum offers centrifugal force peaks of 18,884 lbs and oscillation frequencies with tangential amplitudes of 0.1 inches, complemented by rear oscillation forces up to 26,078 lbs and frequencies reaching 58 vibrations per minute, enabling excellent surface treatment with low amplitude to minimize surface damage. The unit has a compact footprint, with an overall length of 176.4 inches, width of 5 feet, height up to 9.5 feet with cab, and a wheelbase of 131.5 inches, facilitating maneuverability including an inside turning radius of 13.9 feet. It supports a maximum speed of 3.8 mph and includes a 185-gallon water spray tank for drum cooling and dust control. The oscillating angle of 10 degrees enhances drum contact on uneven surfaces, while the 31.8-gallon fuel tank ensures extended work cycles. Its design balances power, precision, and operator comfort for effective compaction in various construction environments.
