About us


JMH has dedicated field service vehicles for onsite machinery repairs and shut downs. We will travel all over Western Australia or interstate to get the job done.

We realise the impact of downtime on the mining and construction industry and we prioritise time critical jobs to get machines and production up and running as fast as possible!


We have quality heavy duty mechanics with extensive industry knowledge.

JMH director/owner, Jaydon Hirst has a specialised knowledge of Komatsu machines having worked with them for over 10 years. Jaydon also has industry management and project management experience.

All of this wealth of knowledge and skills makes JMH the perfect choice for all technical, shut down management and planning requirements.


We have invested in equipping our service vehicles to rival specialised OEM’s, with the advantage of a more competitive labour rate. This puts JMH clients in front every time.

Some of our specialised tools include, 100t and 180t mobile track presses along with a mobile lube service trailer.
