Atlas Copco expands its hydraulic CombiCutter line with the CC 4700

The new CC 4700 demolition cutter for 45-65 ton carrier units completes Atlas Copco’s range. Stability, reliability and low operating costs are the key criteria for the development of this crusher model.

“With the CC 4700 we are responding to the trend towards larger demolition equipment,” explains Wolfgang Hohn, Product Line Manager Silent Demolition Tools, “And we are closing the gap that existed between our CC 3300 and the CC 6000, which was presented at Bauma 2010.”

The CC 4700 follows the design of the entire hydraulic demolition cutter range of Atlas Copco. The system of two articulated arms and two lifting cylinders has been tried and tested: it offers a constant high crushing force throughout the entire closing process. And the combination of one single and one twin blade arm enables maximum stability even under extreme loads. Universal arms (U-version) and Steel cutting arms (S-version) are available for the CC 4700.

The crusher arms are stably mounted on a central main pin, reducing the time required for changing crusher arms by up to 75 %, compared to separate mountings. Both crusher arms can be fitted and removed as a unit, because CAPS, the Coupling and Positioning System, continues to link the two together even after removal.

Crusher arms can be changed on site, thereby avoiding time-consuming and costly transport to the workshop. And the practical concept for wearing parts also saves time: crusher teeth and cutting blades can be turned or changed quickly and easily on site. “We found that about two-thirds of the operating costs of an attachment arises from factors such as energy, operator costs, service and maintenance, and only one-third from the investment costs” adds Wolfgang Hohn, “With the CC 4700 we are focusing on these consequential costs.”

The CC 4700 is designed for use in demolition of industrial facilities, bridges and buildings.
