We manufacture and repair -

  • All hydraulics, from small cylinders through to large double acting, telescopic and specialised hydraulic cylinders.
  • Precision underground equipment including gearbox parts, shearer parts and longwall parts.
  • Above ground mining machinery parts including load rollers and idler rollers to suit any machine.
  • At Colmar we can manage all stages of the manufacturing process and because 99% of production work is completed in-house we provide a quality guarantee on all our work.

Supporting Australian mining since 1987

Colmar Engineering has been working closely with the company originally known as Ardent Underground, now Abergeldie Complex Infrastructure, since 2007.

Abergeldie is an Australian leader in blind bore shaft drilling, a method of mechanised vertical drilling conducted by only a handful of companies worldwide.

Originally developed in Europe in the 1950’s, blind boring was later used for nuclear detonation preparations at the U.S Military’s Nevada Test Site. Today, blind boring is primarily used to construct ventilation and access shafts for underground mining. Our goal has always been to provide a faster, safer and more reliable way of providing large diameter shafts (up to 16m diameter).

Abergeldie has a fleet of four drill rigs which we have designed and built using cutting edge technology. The rigs are designed to drill and line in ground conditions that have been previously considered unmanageable. In short, the equipment sets a benchmark for mechanised shaft excavation.

The drill rig, the largest operating in Australia, consisted of a 450 tonne lifting capacity derrick. The derrick winch was powered by 2 x 160kW variable speed controlled electric motors. The drill head of the rig consisted of 6 x 55kW motors driving into planetary gear reducers combined onto a final drive helical gear, all engineered by Colmar.

The drill head consisted of cutting discs arranged in a hemispherical profile cutting head assembly. The cutting discs are not powered but rotate as the drill head is rotated due to friction of the strata on the discs. The drill head rotated at approximately 5rpm. Controlling the winch and drill head motors by variable speed drives provided precise control over torque and speed.

Colmar Engineering is also trusted by Abergeldie to maintain their fleet and keep them operational.

The biggest drill rig in Australia


Colmar has a long history working with Komatsu, a leading global supplier of technologically innovative utility, construction and mining equipment. We are a trusted partner, our relationship goes back over 30 years to the days of P&H and Joy Mining.

In addition to manufacturing and suppling a large range of OEM spare parts Colmar has recently have been heavily involved in the development of Komatsu's MC51 Continuous Hard Rock Miner.

Working closely with the Komatsu team, Colmar was tasked with the design, engineering and construction of the hydraulic rams, bearing housings and cutter head on this innovative new model.

Colmar now manufactures these components for markets worldwide.
