Epiroc CB 4500 Concrete Buster

Epiroc’s Concrete Busters are dedicated concrete cracking machines for breaking concrete. They are very similar to Combi Cutters/multiprocessors when they are equipped with concrete cutting jaws, but they are stronger in design.

Concrete busters are used for very thick concrete wall structures, such as building foundations or for very tough applications, such as long front demolition where the operator has restricted visibility.

The CB 4500 is for excavators of 40 to 55 tonnes.
