VOLVO SD115B PADFOOT STATIC SMOOTH DRUM ROLLER

Technical Description

The Volvo SD115B Padfoot is a heavy-duty vibratory smooth drum roller designed specifically for soil compaction tasks. It features a turbocharged 4-cylinder Volvo D4 Tier 4 F engine delivering 147.6 hp, supported by a 24V electrical system with an 80A alternator. The machine weighs approximately 26,014 lbs operating weight and offers a fuel capacity of 43.6 gallons and a hydraulic fluid capacity of 20 gallons. Its drum is 51 inches in diameter, 84 inches wide, with a 5-inch pad height and 1-inch shell thickness, providing superior soil kneading over a 21 square-inch pad surface. The drum drive utilizes a planetary gearbox with hydrostatic propulsion, enabling speeds of 2.7 mph (low) and 6.2 mph (high). The SD115B has a ground clearance of 19.7 inches, an overall length of 239.9 inches, width of 7.1 feet, top cab height of 10 feet, and a wheelbase of 121.9 inches. Braking is managed by spring-applied, hydraulically released parking brakes on the drum and axle, and a hydrostatic service brake. The roller incorporates dual amplitude vibration with centrifugal forces reaching up to 58,000 lbs and nominal amplitude of 0.1 inches in both low and high modes, optimizing compaction efficiency. The inside turning radius measures 149.6 inches. The enclosed ROPS/FOPS-certified cab ensures operator safety and comfort. This compactor combines advanced drum control for multiple frequencies and automatic vibration engagement with a variable amplitude system to provide versatility and high performance on varied jobsites.
