MINING EQUIPMENT: DK Heavy Plant Services



DK Heavy Plant Services Pty Ltd is the Hunter Valley’s One Stop Shop for the maintenance, overhaul and rebuild of Mining and Industrial Equipment. We can offer our services to clients in field or in our state of the art workshop facility located on Thomas Mitchell Drive in Muswellbrook.

Formed in 2017 by David Komacha, DK Heavy Plant Services quickly grew from a small group of Plant Mechanics to the 24/7 operation we know today. This operation now offers not only mechanical services but also Fabrication, Line Boring, Electrical and Drafting Services.

Our mechanical team are also available 24/7 for break down and field service repairs. We also have a team of highly skilled Plant Mechanics available to fill leave and overtime requirements on all Hunter Valley mine sites.


Offering both light and heavy fabrication services we are equipped to handle all your boiler making requirements in field and within our workshop environment. We specialise in body, bucket, shovel and blade overhauls. We are also able to offer Sandblasting and Painting services. Roster coverage for field service Boilermakers is also available.

Line Boring

With a fleet of mobile line-boring units and a fully equipped work shop we are able to provide our clients with 24/7 coverage. Our Line Boring team excel in the refurbishment of Equalizer bars, A-Frames, Dog Bones, Track Frames and Axel Boxes.
