Compact Rock Breakers
High performance manoeuvrability
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. 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.
