HAMM HD+ 120I VO (VIB/OSC) STATIC SMOOTH DRUM ROLLER

Technical Description

The HAMM HD+ 120i VO (VIB/OSC) is a high-performance smooth drum roller designed for efficient asphalt compaction. It features a 78-inch width drum with a 55.2-inch diameter and 0.8-inch thickness, providing a static linear load of 177 lb/in. The machine is equipped with a DEUTZ TCD 4.1 L4 engine delivering 154.3 hp, compliant with EPA Tier 4 emissions standards. Operating weight ranges around 28,411 to 30,208 lbs depending on configuration, with a fuel capacity of 68.7 gallons and a water spray tank capacity of 302.5 gallons. The roller offers dual drum operation with vibration frequencies of 40 to 50 Hz for front drum and an oscillation frequency of 36 Hz at the rear, producing oscillation forces up to approximately 39,341 lbs. The oscillation drum utilizes two eccentric shafts rotating synchronously to impart alternating tangential shear forces, enhancing compaction quality and homogeneity. It comes with an articulated steering system, featuring a 10-degree oscillating angle and an inside turning radius of about 235 inches, enabling precise maneuverability. The overall dimensions are approximately 208.7 inches in length, 7.04 feet width, and 9.78 feet height to the cab top. The machine integrates the HAMMTRONIC electronic management system, optimizing engine performance, drive torque distribution, and hydrostatic vibration, which improves operational efficiency, safety, and fuel economy. Additional features include an Easy Drive operating concept, water sprinkling system with dual pumps, foldable scraper, and a vibration-isolated operator platform for comfort and productivity.
