INGERSOLL RAND DD-70 STATIC SMOOTH DRUM ROLLER

Technical Description

The Ingersoll Rand DD-70 is a heavy-duty static smooth drum roller designed for efficient asphalt and soil compaction. It features dual smooth drums, each with a diameter of 41.2 inches and a width of 64 inches, delivering a centrifugal force of up to 17,970 lbs on high amplitude with a constant vibration frequency of 3300 vpm. Powered by a naturally aspirated Cummins 4B 3.9L inline 4-cylinder diesel engine, it produces 80 hp, providing robust performance and reliability. The roller’s operating weight is approximately 15,000 lbs, ensuring substantial ground contact for effective compaction. Dimensionally, the DD-70 offers 22.1 inches of ground clearance, an overall length of 14.7 ft, a wheelbase of 9.8 ft, and a turning radius of 189 inches, making it maneuverable on construction sites. It is equipped with a hydraulic system having a 17-gallon fluid capacity and a fuel tank capacity of 37 gallons. The machine operates at a top speed of 6.6 mph and runs on a 12-volt electrical system supported by a 95-amp alternator. The smooth drum design and dual vibratory system enhance compaction uniformity and surface finish, making it ideal for asphalt paving and other surface preparation tasks. Its cab height at 9.3 ft provides operator comfort and visibility. Overall, the Ingersoll Rand DD-70 combines powerful compaction capabilities with durable, efficient Cummins diesel power for demanding infrastructure and road construction applications.
