HAMM HD+ 90I VO (VIB/OSC) STATIC SMOOTH DRUM ROLLER

The HAMM HD+ 90i VO is a high-performance tandem smooth drum roller designed for asphalt compaction. It features a front vibration drum and rear oscillation drum, both smooth and non-split, with a drum width of 66.1 inches and a drum diameter of approximately 47.3 inches. The machine operates with dual vibration frequencies of 42 Hz and 50 Hz (equivalent to 2,520 and 3,000 vibrations per minute), producing centrifugal forces of 18,000 lbs and 13,500 lbs respectively for effective compaction. Powered by a Deutz TCD 3.6 L4 four-cylinder engine delivering 114 hp, this roller has an operating weight around 20,300 to 21,500 lbs and fuel capacity near 45.8 gallons, supporting extended operation. Its operating width is about 70.5 inches with an inside turning radius of approximately 232 inches (19.85 ft), facilitating maneuverability on job sites. The roller is equipped with a 220-gallon water spray tank to prevent asphalt sticking and incorporates HAMMTRONIC electronic machine management, controlling engine speed, vibration drives, and braking for fuel efficiency, safety, and optimized compaction. The articulated steering with a 3-point joint ensures excellent driving safety and comfort. Drum thickness is 0.7 inches, with static linear load around 164 lb/in. Maximum travel speed is roughly 3.8 mph, and ground clearance is approximately 31.5 inches. The oscillation drum utilizes two eccentric shafts rotating synchronously to apply tangential shear forces, delivering homogeneous compaction with improved quality and productivity. Overall dimensions include a length near 193 inches, width around 71 inches, and height up to 9.8 feet to the top of the cab. This model meets EPA Tier 4 and EU Stage V exhaust emission standards, making it efficient and environmentally compliant.
