HAMM HD+ 90I PH VO-S STATIC SMOOTH DRUM ROLLER

The HAMM HD+ 90i PH VO-S is a tandem smooth drum roller designed for high-quality asphalt compaction. It features a front smooth split drum and a rear smooth non-split oscillation drum, providing excellent compaction performance with reduced surface stress. The machine is powered by a DEUTZ TCD 2.9 L4 four-cylinder diesel engine delivering 74.2 hp (55 kW) at 2300 rpm, meeting EPA Tier 4 emissions standards. It has a drum width of 66.2 in, a drum diameter of 47.3 in, and a drum shell thickness of 0.7 in. The roller offers two vibration frequencies (42 vpm and 50 vpm) with a nominal amplitude of 0.1 in, generating centrifugal forces of 18,884 lbs (high) and 17,535.1 lbs (low). The rear oscillation drum provides a tangential amplitude of 0.1 in and an oscillation frequency of 39 vpm, with an oscillation angle of 10 degrees. Static linear load is 164.1 lb/in. The machine has an operating weight of 26,455.5 lbs, with a cab-equipped operating weight of 20,855.8 lbs and a ROPS operating weight of 20,481 lbs. It has a maximum speed of 3.8 mph and a wheelbase of 141.8 in, with a 19.4 ft inside turning radius and 31.5 in ground clearance. Fuel capacity is 45.8 gal and the water spray tank holds 220.4 gal.
