The HYPAC C747C is a smooth drum roller designed for efficient compaction tasks on construction sites. It features a drum diameter of 18.8 inches and a drum width of 47.3 inches, delivering a static linear load of 60.5 pounds per inch, which ensures effective soil compaction. The roller operates with a vibration frequency range between 3300 and 3960 vibrations per minute (vpm), with nominal medium amplitude of 0.1 inches to optimize compaction quality. Powered by a Deutz D 1703 MDI diesel engine, the machine develops 34.3 horsepower (25 kW) at 2700 rpm from its 3-cylinder configuration, offering reliable and efficient performance. Key dimensions include an overall width of 4.5 feet, an overall length of 8.2 feet, and a ground clearance of 9.9 inches, allowing maneuverability in diverse terrains. The roller has a wheelbase of 5.7 inches and an inside turning radius of 8.6 feet, enhancing operational control. It carries a fuel capacity of 10.6 gallons, supporting sustained operation with a maximum speed of 7.5 mph (11 kph). Electrical systems run at 12 volts. The operating weight of the unit is 5732 pounds, providing sufficient mass for effective compaction without sacrificing mobility. The design and specifications of the HYPAC C747C combine robust vibration technology and a powerful, reliable engine, making it suitable for a wide range of medium-scale earthwork compaction applications.
