The Komatsu JV40CW-3 is a compact, single-drum vibratory smooth drum roller designed for efficient asphalt and soil compaction. Featuring a front drum diameter of 31.5 inches (2.7 feet) and a width of 51.2 inches, it delivers a centrifugal force of 5,510 lbs at a vibration frequency of 55 VPM, enabling effective density enhancement for construction surfaces. The roller is powered by a reliable Komatsu 3D84E diesel engine, a 3-cylinder, direct-injection unit with an 87.3 cubic inch displacement producing 27.7 horsepower at 2,700 rpm, balancing power with fuel efficiency supported by a 12.5-gallon fuel tank. Compact dimensions include an overall length of 10.2 feet, width of 4.6 feet, height to the top of the cab at 5.8 feet, a wheelbase of 7.6 feet, and a ground clearance of 9.9 inches, facilitating maneuverability in tight job sites. The machine’s operating weight is approximately 7,937 lbs, providing sufficient mass for compaction without sacrificing agility. Its maximum speed reaches 7.5 mph, suitable for controlled compaction passes. The sturdy build and optimized vibration characteristics make the JV40CW-3 ideal for various paving and construction projects requiring smooth, uniform compaction. This model integrates Komatsu’s durability and engine technology, allowing for consistent performance in demanding field conditions.
