The Hypac C330B (4-6 ton) Static Smooth Drum Roller is designed for efficient soil and asphalt compaction. It features dual smooth steel drums with diameters of 2.9 ft (front) and 4 ft (rear), providing effective compaction over a 7.1 ft wide operational width. The roller’s compact design includes a 13.3 ft overall length, 9 ft wheelbase, 1.3 ft ground clearance, and stands 5.9 ft tall with an 8.7 ft height to the top of the ROPS/FOPS for operator safety. Powered by a Cummins A2300 4-cylinder diesel engine producing 47 hp at 2600 rpm, it balances power and durability. The cooling system holds 4.8 gallons of fluid, and it stores 17 gallons of fuel. The hydraulic system fluid capacity is 15 gallons, supporting smooth operational controls. Maximum travel speed reaches 11 mph. The roller is equipped with a 100.2-gallon spray water system to prevent material buildup on the drums during operation. Its static linear load capacity is 191 pounds per inch on the drive drum and 126 pounds per inch on the guide drum, providing strong compaction forces. Operating weights range up to 13,047 lbs with ballast and 10,347 lbs in standard configuration, enabling versatility across jobsite conditions. The machine runs on a 12-volt electrical system, ensuring reliable starts and operational support. Overall, the Hypac C330B is engineered for reliable performance in medium-duty compaction tasks with robust engine power, effective drum design, and operator safety features.
