HYPAC C855D STATIC SMOOTH DRUM ROLLER

Technical Description

The Hypac C855D is a heavy-duty static smooth drum roller designed for effective soil and asphalt compaction. It features a robust Cummins QSB4.5 4-cylinder engine delivering 160 hp at 2200 rpm, supporting a maximum operating speed of 7.5 mph. The roller’s static weight is 26,540 lbs, optimizing compaction efficiency with a static linear load of 182.6 pounds per inch. The smooth steel drum measures 59.1 inches in diameter and 83.9 inches in width, operating with a vibratory frequency range of 1800 to 2160 vpm and nominal medium amplitude of 0.1 inches, which ensures consistent, high-quality compaction. Key dimensions include a ground clearance of 19.3 inches, an overall width of 7 feet, and an inside turning radius of 11.9 feet, providing agility on job sites. The cab height stands at 9.8 feet, with a wheelbase of 9.8 feet for stability. It runs on dual 23.1-26/12PR tires and utilizes a 12-volt electrical system. Fuel capacity is 66.1 gallons, allowing prolonged operation in the field. This roller’s smooth drum design suits granular soils and asphalt applications, delivering a uniform, finished surface suitable for further construction phases. Its balance of power, weight, and vibration settings makes the Hypac C855D ideal for infrastructure, roadwork, and large-scale compaction projects requiring precision and durability.
