DYNAPAC CA602D STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA602D is a robust static smooth drum roller designed for heavy-duty compaction tasks, particularly suited for rock fill and base course layers. It features a 62-inch diameter smooth drum with a width of 94 inches, delivering centrifugal forces ranging from 51,931 lbs (low amplitude) to 71,265 lbs (high amplitude), with vibration frequencies between 29 and 31 vibrations per minute. The drum amplitude is nominally constant at 0.1 inch, facilitating effective compaction with high precision. Powered by a water-cooled Cummins QSB 6.7 turbo diesel engine with aftercooler, it generates 190 hp at 2200 rpm, enabling a maximum travel speed of 6.9 mph. The roller weighs approximately 41,000 lbs and has a fuel capacity of 84.6 gallons, allowing for extended operation. Its dimensions include a ground clearance of 17.8 inches, overall length of about 19.7 feet, width near 7 feet, a cab height of 9.8 feet, and a wheelbase around 9.9 feet, optimized for maneuverability and stability on-site. The CA602D runs on large 23.1x26 tires and is equipped with an all-wheel-drive system to improve traction on rough terrain. The roller’s design supports compacting thick layers—up to 1.8 meters of rock fill—making it highly effective for base course and subbase applications in road construction and heavy civil engineering projects.
