The best choice for your plant



Our in house Machine Shop allows for expensive componentry to be reclaimed, or like for like components to be manufactured in a timely and cost-effective manner. This offers an alternative to costly and often lengthy lead times available on OEM componentry, reducing the total cost of ownership of your equipment.


Cloncurry based

A convenient location allows for operational critical components to be efficiently sent offsite to our workshop during maintenance outages or shutdowns. So, your components can be sent for work by the GNH workshop team, and then be return for install prior to shutdown completion. This minimises site shutdown labour and supervision requirements, and potential safety risks involved with insitu work.
