HAMM HD+ 70 VO (VIB/OSC) STATIC SMOOTH DRUM ROLLER

Technical Description

The HAMM HD+ 70 VO (VIB/OSC) is a high-performance smooth drum roller designed for advanced compaction tasks. Featuring a 59-inch wide drum with both vibration and oscillation capabilities, it enables efficient and high-quality soil and asphalt compaction. The oscillation drum uses two eccentric shafts rotating synchronously at 180°, creating a forward-backward drum movement that delivers tangential shear forces for superior, homogeneous compaction results. This method achieves faster and more effective compaction compared to traditional vibration alone. The roller is powered by a reliable Deutz engine, providing robust and efficient operation. Its turning radius measures 166.5 inches, offering excellent maneuverability in confined areas. The unit's operating width is 63.4 inches, slightly wider than the drum width for effective coverage. Operating weight is approximately 7,445 kg (16,414 lbs) with standard ROPS, enhancing stability during operation. Fuel and water tank capacities are 31.7 US gallons (120 liters) and 184.9 US gallons (700 liters), respectively, supporting extended service intervals and enabling water spray for drum vibration cooling and dust control. The HAMMTRONIC machine management system optimizes engine speed, vibration drive, and torque distribution, improving fuel efficiency, machine safety, and operational smoothness. Overall, the HD+ 70 VO roller combines innovative oscillation technology with powerful vibration and intelligent control systems for improved compaction performance, increased productivity, and smooth operation in road construction and earthwork projects.
