HAMM H25I STATIC SMOOTH DRUM ROLLER

Technical Description

The HAMM H25i Static Smooth Drum Roller is a robust compaction machine designed for efficient soil and asphalt compaction. It features a smooth drum with a width of 84.3 inches (2140 mm) and a diameter of 63 inches (1600 mm), equipped with a 1.8-inch thick steel drum providing a static linear load of 776 pounds per inch. The machine delivers high centrifugal forces of 74,475 lbs and low forces of 54,450 lbs with vibration frequencies of 27 and 30 vpm, generating nominal amplitudes of 0.08 and 0.047 inches for effective compaction. Powered by a Deutz TCD 6.1 L6 diesel engine producing 214.6 hp at 2300 rpm, it meets EU Stage V and EPA Tier 4 emission standards through DOC-DPF-SCR exhaust after-treatment. The roller has a maximum operating weight of approximately 55,000 lbs, a fuel capacity of 74 gallons, and offers a maximum speed of 12 mph. Its articulated steering with a 10-degree oscillation angle and a turning radius of 13.8 feet ensures excellent maneuverability on slopes with front and rear driving angles of 43 and 28 degrees, respectively. The H25i boasts a ground clearance of 15.4 inches, a wheelbase of 128.6 inches, and a cab height of 9.8 feet for operator comfort and visibility. The rear tires are EM 23.5-R25 XTLA, supporting heavy loads and durability. This machine's design integrates ergonomic features such as a spring-mounted driver seat and clear information displays, optimized for high performance and operational efficiency in road construction and earthwork applications.
