HYPAC C350D STATIC SMOOTH DRUM ROLLER

Technical Description

The HYPAC C350D is a static smooth drum roller designed for efficient soil and asphalt compaction in road, site preparation, and infrastructure projects. It features a tandem smooth drum configuration with a 54-inch drum width, a front drum diameter of 4.1 ft, and a rear drum diameter of 5.1 ft, providing consistent ground contact and uniform compaction. The machine is powered by a Cummins 4B3.3TAA 4-cylinder diesel engine delivering 78 hp at 2100 rpm, coupled with a hydrostatic transmission for smooth, stepless speed control and excellent traction. Maximum travel speed reaches 10.2 mph (16 km/h), supporting productive job site mobility. Operating weight ranges from 17,320 lbs standard to 24,250 lbs with maximum ballast, with static linear loads of 251 lbs/in on the drive drum and 198 lbs/in on the guide drum for effective compaction performance. The C350D has an overall length of 16.6 ft, width of 5.3 ft, wheelbase of 11.7 ft, and ground clearance of 1.7 ft, offering a stable, maneuverable platform. Additional technical specifications include a 30.2-gallon fuel tank, 170.4-gallon spray water system, 15-gallon hydraulic reservoir, and a 12-volt electrical system, making it a robust, field-ready compaction solution.
