SAKAI SV512D STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai SV512D is a static smooth drum roller engineered for high-efficiency soil compaction in large-scale earth-moving projects. It features a robust turbocharged Perkins 1004-40TW diesel engine with 114.7 hp and 243.5 cu in displacement, delivering power at 2200 rpm. The roller’s overall dimensions include an 18.8 ft length, 7.5 ft width, and 9.3 ft height to the top of the cab, with a wheelbase of approximately 9.7 ft and ground clearance of 17.1 inches. Weighing about 23,150 lbs, it provides excellent traction and slope climbing capabilities due to a well-balanced front and rear weight distribution. The compaction drum measures 60.3 inches in diameter and 83.9 inches in width, equipped with a dual-frequency, dual-amplitude vibration system. It generates centrifugal forces of up to 50,807 lbs on high and 38,667 lbs on low settings, with nominal amplitudes of 0.1 inches and vibration frequencies of 36.7 Hz and 27.5 Hz respectively, allowing efficient compaction of varied materials. The hydraulic fluid system holds 13.3 gallons, and fuel capacity is 66.1 gallons, supporting a maximum speed of 6.3 mph. The roller operates on a 24-volt electrical system and features 23.1-26-8PR tires. Safety is enhanced by dual independent braking systems, including a hydrostatic primary brake engaged via the forward-reverse lever. Ergonomic controls, vibration isolation, and a cushioned adjustable seat ensure operator comfort and reduced fatigue during extended use.
