SAKAI SW651ND STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai SW651ND is a static smooth drum roller designed for effective soil and asphalt compaction. It features a single smooth drum measuring 42.2 inches in diameter and 58 inches in width, enabling uniform pressure distribution over surfaces. The roller is powered by a reliable Hino W04D-H diesel engine with a displacement of 244.7 cubic inches, delivering 75.1 horsepower at 2050 rpm, ensuring strong performance for various compaction tasks. It has an operating weight of approximately 16,314 pounds, contributing substantial ground contact force for optimal compaction results. The roller’s ground clearance is 10.9 inches, with an overall width of 5.3 feet, height to the top of the cab at 9.2 feet, and an overall length of 13.9 feet. Its turning radius inside measures 139 inches, and the wheelbase is 9.9 feet, offering good maneuverability in confined job sites. The machine operates on a 24-volt electrical system and has a fuel capacity of 31.8 gallons, allowing extended operation without frequent refueling. Its vibration system includes a frequency of 2940 vibrations per minute (vpm) at 49 Hz, optimizing soil particle rearrangement for compaction efficiency. The maximum travel speed is 7.5 mph (11 kph), balancing pace with compaction quality. Overall, the SW651ND combines robust power, precise vibration control, and practical dimensions making it suitable for heavy-duty compaction applications in road construction and groundwork projects.
