The Ammann ASC250HD static smooth drum roller is a high-performance compaction machine designed for efficiency and durability on demanding job sites. It features a 67-inch diameter front drum that is 88.2 inches wide, providing a substantial compaction surface. The drum delivers a centrifugal force ranging from 76,435 lbs to 103,412 lbs with two vibration frequencies of 28 and 34 vibrations per minute, both at a nominal amplitude of 0.1 inches, ensuring consistent and effective soil compaction. The static linear load is 439.1 pounds per inch, enhancing its ability to handle dense materials. Powered by a Cummins QSB6.7-C220 engine, the roller offers a net power output of 208 horsepower (155 kW), with a fuel capacity of 107 gallons, enabling extended operation without frequent refueling. The maximum speed is 6.3 mph (10 kph), suited for controlled compaction work. Its operating weight is approximately 55,843 lbs, contributing to optimal ground pressure. The machine’s dimensions include a ground clearance of 19.7 inches, a height of 10.8 feet to the top of the cab, an overall length of 21.6 feet, a width of 8.3 feet, and a wheelbase of 10.8 feet. Equipped with 23.5-25 tires, it ensures stability and traction. The operator’s cabin offers ergonomic comfort and visibility, supporting long working shifts. This model emphasizes reliability with features such as hydrostatic transmission for maximum traction and stability, making the ASC250HD suitable for a wide range of soil compaction applications in construction and infrastructure projects.
