DYNAPAC CC334 HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC334 HF is a static smooth drum roller designed for efficient compaction in road construction and asphalt paving. It features a 68-inch wide drum with a diameter of 45 inches and a shell thickness of 0.7 inches, providing a compaction width of 68 inches. The roller’s operating mass is approximately 19,800 lbs, with a maximum operating mass of 21,800 lbs, evenly distributed as 9,900 lbs per front and rear module. It has an inside turning radius of 1.5 feet and an overall width of 5.7 feet, allowing for maneuverability in confined workspaces. The drum frequency ranges from 50 to 67 vibrations per minute, optimized for smooth compaction surfaces. Powered by a Cummins QSB3.3T3 diesel engine, the CC334 HF delivers a rated power output of 100 hp at 2,200 rpm, supported by a 34-gallon fuel tank. Its static linear load is 146 lbs/in front and rear, enabling effective soil and asphalt density improvement. The roller’s height is 89 inches without the ROPS/cab and 118 inches with ROPS, ensuring operator safety and comfort. The machine offers a maximum theoretical gradeability of 35%, making it capable of operating on moderate slopes. This model balances robust power, precise compaction control, and compact dimensions suitable for a variety of medium-duty compaction tasks.
