VOLVO SD77F STATIC SMOOTH DRUM ROLLER

Technical Description

The Volvo SD77F Static Smooth Drum Roller is a robust soil compaction machine designed for efficient and effective compaction across granular to cohesive soils. It features a 66-inch-wide smooth drum and an operating width of 74 inches, with an overall width of 7 feet. The front drum diameter measures 48 inches. The roller operates with a centrifugal force of approximately 29,900 lbs at both high and low settings, providing significant compaction impact. The operating weight is around 17,780 lbs, ensuring sufficient downward force to compress materials effectively. It has a fuel capacity of 47.1 gallons and hydraulic system fluid capacity of 22.2 gallons, supporting extended operational periods. The machine can reach a maximum speed of 9.6 mph, balancing compaction performance with mobility. The vibration frequency ranges from 1850 to 2025 vibrations per minute (vpm), with a specific vibration frequency around 33.8 vpm, which enhances the compaction efficiency by inducing soil particle rearrangement. The SD77F’s design optimizes soil density and achieves uniform compaction for various construction, roadwork, and earthmoving projects. Its powerful engine and hydraulic system enable smooth control and reliable performance in diverse conditions. Overall, the Volvo SD77F is a medium-duty smooth drum roller tailored for high productivity in soil compaction applications requiring precise soil density control.
