Atlas Copco has introduced the CC 4700 CombiCutter, a 4,750 kg (10.450 lb) tool intended for carriers weighing from 45 to 65 tonnes that fills the gap between the CC 3300 and CC 6000 (the latter was launched at Bauma 2010). This new attachment is available with either a universal jaw set or a steel cutting jaw, and follows the design of the company's other CC attachments.

According to Wofgang Hohn, product line manager silent demolition tools, "With the CC 4700 we are responding to the trend towards larger demolition equipment. And we are closing the gap that existed between our CC 3300 and the CC 6000."

The new tool consists of two articulated arms and two lifting cylinders that has been tried and tested - according to Atlas Copco, it offers a constant high crushing force throughout the entire closing process.

One of the key design criteria that Atlas Copco has tried to address is low operating cost. According to Wolfgang: "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 cost. With the CC4700 we are focussing on these consequential costs."

Crusher arms are mounted on a central main pin, reducing changeover times by as much as 75 % compared to separate mountings.

Both arms can be fitted and removed as a unit through the use of Atlas Copco's Coupling and Positioning System (CAPS) on site. The crusher teeth and cutting blades can also be quickly and easily changed on site.
