Tamping Compactor

By On-Site   


The Dynapac CT3000 tamping compactor has been designed to efficiently achieve specified densities on cohesive and semi-cohesive soils. With an operating weight of 22 tons, and an average production capacity of 900 cubic meters per hour, the Dynapac CT3000 is ideal on projects such as highways, dams and airport runways where large volume earthwork is required. Driven by a Tier 4F turbo-diesel engine, it features an automatic 4-speed transmission providing all-wheel traction for high productivity. The front oscillating axle works independently of the optional strike-off blade and the rigid rear axle. This enables the blade to work in a permanently level position and ensures uniform distribution of soil on any type of terrain. The square pads of the compacting drums have been optimized in size and pattern to maximize the energy transmitted to the soil, which helps produce uniform compaction density with minimum scarification. The drums are offset by the width of a pad so that the rear drum compacts areas that have not been compacted by the front drum. A double pass of the machine results in a compaction width of 4.4 meters. Each drum is equipped with two sets of adjustable scrapers made of tempered steel. The hydrostatic steering allows a steering angle of 40 degrees to either side and a turning radius of less than 6.3 meters. The CT3000 can be equipped with an optional 2-way, 4-way or 6-way strike-off tilting and levelling blade. It allows the operator to set hydraulically the raising movement, performing inclinations and adjustments simultaneously. The versatility of the blade allows the machine to operate in several types of applications. www.atlascopco.com.
