Compact Rock Breakers
High performance in a cost effective package
Commonly used in civil construction, demolition, trenching, and smaller quarry work, the DEMCO gas-series breakers pack a powerful punch in a lightweight, portable package. High impact force is generated by a nitrogen gas pressure working together with the hydraulic pressure of the host machine at the top of the piston. This is effective rock-breaking power and performance at a lower initial investment – making it a great choice for Australian operators. Our customers can also rest easy knowing Earthworm has the backup and parts stock available to keep you operating.
