DYNAPAC CA612 STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA612 Static Smooth Drum Roller is a robust single-drum compaction machine designed for heavy soil compaction tasks. It features a smooth steel drum with a width of 83.9 inches (2130 mm) and a diameter of 62 inches (1573 mm), constructed with a 50 mm thick shell for long service life and durability. The roller is powered by a Cummins QSB 6.7 turbocharged water-cooled diesel engine with aftercooler, delivering 190 hp at 2200 rpm, ensuring strong and efficient performance. The overall operating weight of the machine is approximately 45,635.7 pounds, providing substantial ground contact for effective soil compaction. The CA612 supports dual vibration frequencies at 29 and 31 Hz, with a nominal amplitude of 0.1 inches, producing a high centrifugal force of up to 71,264.5 pounds to optimize compaction force and soil density. It offers a maximum travel speed of 6.9 mph, enabling efficient site coverage. The roller has significant ground clearance of 17.72 inches and a wheelbase of 9.82 feet, contributing to stable maneuverability over rough terrain. Dimensions include an overall length of 20.28 feet, width of 6.99 feet, and height to cab top of 9.76 feet, facilitating operator comfort and visibility. Equipped with 23.1x26 tires and an 84.6-gallon fuel tank capacity, the Dynapac CA612 is designed for sustained, heavy-duty operation on large-scale construction and road-building projects, where precise, powerful soil compaction is essential.
