DYNAPAC CC7200 STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC7200 is a large tandem static smooth drum roller designed for high-efficiency compaction on major road and infrastructure projects. With an operating weight of 37,037.7 lb (16,800 kg) and a maximum operating mass of 39,650.2 lb (17,985 kg), it delivers a static linear load of 216.8 lb/in and a drum width of 83.9 in (2,130 mm), ensuring uniform and effective compaction across wide surfaces. The machine is powered by a Cummins QSB 6.7 IIIA water-cooled, after-cooled diesel engine rated at 228 hp (170 kW) at 2,100 rpm, meeting Tier 4 emissions standards. It features a hydrostatic drive system with a speed range of 0–10 km/h (6.9 mph) and a theoretical gradeability of 31%, supported by a wheelbase of 147.8 in and an inside turning radius of 19.6 ft for improved maneuverability. The CC7200 is equipped with a robust water spray system (354 gal capacity) to prevent material adhesion. Braking is handled by a hydrostatic service brake integrated into the forward/reverse lever and a failsafe multidisc brake on both drums and wheel motors for secure parking and emergency stopping. With a ground clearance of 15.8 in, overall length of 222.6 in, and height to the top of the cab of 11.3 ft, the CC7200 combines heavy-duty performance with operator comfort and control for demanding compaction applications.
