The 2024 HAMM HC120i static smooth drum roller is a powerful compactor designed for efficient soil and asphalt compaction. It features a 131 hp engine with a 276 cubic inch displacement, delivering robust performance. The machine has an operating weight of 28,500 lbs and a fuel capacity of 66 gallons, enabling extended operation on the job site. Its front drum is smooth, 84 inches wide, and 60 inches in diameter, providing a static linear load of 185 lb/in. The roller operates at a vibration frequency of 30 Hz, generating a centrifugal force of 16,000 lbs to enhance compaction effectiveness. It can achieve a maximum travel speed of 7 mph and offers a gradeability of 55% without vibration, suitable for varying terrains. The inside turning radius measures 138 inches, contributing to its maneuverability in confined spaces. The roller is equipped with an electronically controlled engine and hydrostatic drive system, ensuring optimized power distribution and smooth operation. The drum thickness is about 1 inch, and the machine incorporates advanced features such as HAMMTRONIC electronic management for improved fuel efficiency, safety, and ease of use. Its dimensions and operating features make the HC120i ideal for medium to large-scale compaction projects requiring high performance, reliability, and operator comfort. This model represents a balance of power, precision, and efficiency in the HAMM compactor lineup.
