VOLVO DD70HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Volvo DD70HF is a high-performance static smooth drum roller designed for efficient asphalt compaction. It features a 57-inch wide smooth drum that delivers a vibration frequency of 66.7 vibrations per minute (vpm), providing effective soil and asphalt compaction with a centrifugal force ranging between 7,820 and 21,080 pounds. Powered by a robust Cummins engine producing 84.5 horsepower, the roller has an overall operating weight of 14,895 pounds, with nearly equal static weight distribution between the rear drum (7,485 lb) and front drum (7,300 lb), ensuring optimal ground contact and stability. Its compact design includes an overall width of 5.5 feet and an inside turning radius of 15.8 feet, allowing maneuverability in confined spaces while maintaining high productivity. The machine’s vibration nominal amplitude ranges from 0.006 to 0.017 inches, which aids in achieving uniform compaction quality. The overall length of the DD70HF is 176 inches. This model balances power, weight, and precision, making it ideal for asphalt and base layer compaction in a variety of road construction and maintenance projects. Its durability and Cummins engine reliability contribute to reduced downtime and maintenance costs on site. The Volvo DD70HF’s specifications and performance capabilities make it a versatile choice within the smooth drum roller category for contractors seeking consistent and efficient compaction results.
