HAMM HD+ 120 VO STATIC SMOOTH DRUM ROLLER

Technical Description

The HAMM HD+ 120 VO is a robust smooth drum roller designed for efficient compaction in road construction and related applications. It features a 78-inch wide, 55.2-inch diameter smooth non-split drum with a thickness of 0.8 inches, providing strong surface contact. The drum generates centrifugal forces of 35,744.7 lbs (high) and 21,356.9 lbs (low) with vibration frequencies ranging between 2400 to 3000 vpm, and nominal amplitude fixed at 0.1 inch for both high and low settings, ensuring consistent compaction quality. Powered by a DEUTZ TCD 2012 L04 2V diesel engine with 134.2 hp and 4 cylinders, it balances power and fuel efficiency with a fuel capacity of 47.6 gallons. The roller’s operating weight is approximately 29,740 lbs with a cabin height of 10.1 feet and an overall length of 196.9 inches. It offers a tight turning radius of 1.4 feet, with a steering angle of 10 degrees, ensuring maneuverability in confined sites. The integrated water spray system holds 306.5 gallons to keep the drum wet, preventing material pickup during operation. The maximum speed is 3.8 mph, optimized for controlled compaction. The unit incorporates advanced technology such as HAMMTRONIC electronic machine management for automated processes and improved operational safety. Its combination of vibration and oscillation drum technology enhances compaction efficiency, delivering more uniform density across treated surfaces.
