SAKAI TW320-1 STATIC SMOOTH DRUM ROLLER

Technical Description

The Sakai TW320-1 is a static smooth drum roller designed for efficient compaction tasks in asphalt and road construction. It features a 47-inch wide drum with a vibration frequency of 66.7 Hz (approximately 4,000 vpm), providing optimal impact spacing for effective surface smoothing and compaction. The roller’s compact dimensions include an overall width of 4.3 feet, an inside turning radius of 8.6 feet, a length of 104 inches, a height of 69 inches, and a wheelbase of 77 inches, facilitating maneuverability on various job sites. Powered by a robust Kubota D1703-M-ET01 diesel engine, this 3-cylinder, water-cooled, 4-cycle engine delivers 35 horsepower (26 kW) with a displacement of 1.647 liters (100.5 cu.in). The engine is known for its durability, high power output through an E-TVCS indirect injection system, and low noise levels due to features like a half-float valve cover and coated pistons. The Kubota engine ensures quick cold starts with a super glow system and complies with emissions standards for industrial machinery. Weighing approximately 5,975 to 6,329 lbs (2,710 to 2,871 kg), the TW320-1 distributes load evenly with 3,110 lbs on the front axle and 2,865 lbs on the rear axle, contributing to stable and consistent compaction performance. Articulated steering and all-drum drive enhance control and traction, making it suitable for compact to medium-size pavement projects where reliable vibration and smooth finish are critical.
