SAKAI SW651B STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai SW651B is a static smooth drum roller engineered for high-efficiency compaction tasks. It features a robust 42.2-inch diameter and 58.3-inch width smooth steel drum delivering a low centrifugal force of 15,062 lbs, ensuring consistent pressure for uniform soil or asphalt compaction. Powered by the W04D-H engine with a displacement of 244.7 cubic inches, it generates 75.1 horsepower at 2050 rpm, providing reliable power for heavy-duty rolling operations. The roller has a compact footprint with an overall length of 13.9 feet, width of 5.3 feet, wheelbase of 9.9 feet, and a cab height of 9.2 feet, enabling maneuverability in constrained workspaces. It offers a ground clearance of 10.9 inches and operates at a maximum speed of 7.5 mph, supporting effective site coverage. Vibration frequencies of 67 and 50 vibrations per minute enhance the compactive effort, reducing voids and increasing soil density where needed. The machine runs on a 24-volt electrical system and has a fuel capacity of 31.8 gallons, allowing extended operation without frequent refueling. With an operating weight of 17,637 pounds, the SW651B delivers substantial ground pressure for stable, high-quality compaction performance. Its static operation, combined with precision vibration settings, makes it suitable for various road construction, base work, and pave finishing applications where smoothness and compaction consistency are critical. This equipment balances power, size, and operational control for reliable roller performance on diverse job sites.
