The Sakai R2-1 Static Smooth Drum Roller is a versatile compaction machine designed for asphalt and base work, featuring a three-wheel configuration with equal static linear pressure across all drums to ensure uniform compaction. The front and rear drums each measure 5.4 feet in diameter, providing a smooth finishing surface. Powered by a W04D-F diesel engine with a displacement of 244.7 cubic inches, it delivers a gross power of 75.1 hp at 2050 rpm. The roller has a maximum speed of 10 mph, suitable for various paving applications where vibration is not permissible. It offers an operating weight of 20,503 lbs in standard configuration, which can increase up to 27,116.9 lbs with maximum ballast for enhanced compaction force. The ground clearance is 1.2 feet, with an overall width of 6.9 feet, a height of 8.6 feet (10.1 feet to top of ROPS/FOPS), a wheelbase of 11.2 feet, and a compact length of 16.5 feet. The machine features heavy-duty construction for durability, hydrostatic all-drum drive for smooth operation, and a Roll Over Protective Structure/Falling Object Protective Structure (ROPS/FOPS) for operator safety. The static linear load is rated at 775.2 pounds per inch on the drive drum and 813.6 pounds per inch on the guide drum, providing strong compaction performance for asphalt paving and road base layers, especially where thin lifts and no-vibration conditions are required. This roller excels in achieving dense, smooth surfaces with high efficiency and reliability.
