HAMM HD+ 90I PH VO STATIC SMOOTH DRUM ROLLER

The HAMM HD+ 90i PH VO is a high-performance smooth drum roller designed for efficient asphalt compaction. It features a 66.2-inch wide, 47.3-inch diameter front drum with 0.7-inch thickness, delivering centrifugal forces of 16,861 lbs (high) and 13,489 lbs (low) to ensure thorough compaction. The drum incorporates oscillation technology with an oscillation force of 28,776 lbs and frequency of 39 VPM, providing superior surface smoothness by applying alternating shear forces that reduce material displacement and surface cracking. Powered by a DEUTZ TCD 2.9 L4 four-cylinder engine compliant with EPA Tier 4 emissions, it produces 74.3 hp at 2300 rpm, combining diesel power with a hydraulic hybrid system for peak load efficiency. The machine has an operating weight of approximately 25,926 lbs, a ground clearance of 31.5 inches, and dimensions suited for maneuverability with a 19.4 ft inside turning radius and a 141.8-inch wheelbase. It operates at a top speed of 3.8 mph, supported by a 45.8-gallon fuel tank and a 220.4-gallon water spray system to prevent asphalt sticking. The articulating frame with a 10-degree oscillating angle enhances steering and driving comfort on uneven surfaces. HAMMTRONIC electronic management optimizes engine speed, vibration control, and drive torque distribution, increasing fuel efficiency, safety, and ease of use. These features make the HD+ 90i PH VO ideal for high-quality, precise compaction tasks in road construction and infrastructure development.
