The Epiroc range of concrete busters are suitable for excavator carriers between 2 tonnes and 85 tonnes in weight and are designed and built specifically to break concrete. They are similar to the Combi Cutters in design but are much stronger in their design as they are primarily used for thick concrete wall structures, building foundations and all tough applications where the attachment is put under its maximum continuous loading. Even the smallest CB350 which fits on excavator carrier weights of between 2 and 8 tonnes has a massive 40 tonne crushing force on the jaw tip, but only has a service weight of 320kg.
