The HYPAC C340C is a robust static smooth drum roller designed for heavy-duty compaction tasks, offering an operating weight range from 16,226 lbs standard to a maximum ballast of 21,116 lbs. It features dual smooth steel drums with front and rear diameters of 3.4 ft and 4.5 ft, respectively, providing strong ground contact for effective surface compaction. The roller measures 15.3 ft in length, 5.3 ft in width, and stands 6.2 ft high to the frame, extending to 9 ft with ROPS/FOPS for operator safety. Powered by a Cummins 4B3.3TAA four-cylinder diesel engine delivering 84 horsepower at 2400 rpm, it ensures reliable and efficient power output. The machine houses a 30.2-gallon fuel tank, a 4-gallon cooling system, and a hydraulic fluid capacity of 15 gallons, supporting extended operation and system responsiveness. Capable of reaching a maximum speed of 10.2 mph, it is well-suited for asphalt and base compaction on road and foundation projects. The compactor has a high static linear load of up to 246 pounds per inch on the drive drum and 176 pounds per inch on the guide drum, enhancing compaction force distribution. A 170.4-gallon spray water capacity aids in drum surface moisture control to prevent material sticking during asphalt roller operations. Its 12-volt electrical system supports all standard operational and safety features. Overall, the HYPAC C340C combines substantial compaction power, precision drum dimensioning, and operator protection, making it ideal for medium to heavy civil construction compaction applications.
