Mechanical installation services
WJC installs new and replacement equipment from setting out and lifting into place through to alignment, commissioning and handover. Our fitters, boilermakers and riggers work as one crew, so pumps, gearboxes, conveyors and fixed plant go in square, level and ready to run.
We handle mechanical installation on gas facilities, mine sites, power stations, solar farms and farms across the Western Downs and Surat Basin, working to your drawings, permits and site safety system.
