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 the most readily available rock breaker in New Zealand. With hundreds of DEMCO Rock Breakers operating all through the country, customers can rest easy knowing Earthworm has the backup and parts stock available to keep you operating.
