Dragline Crane Overhaul, Bowen Basin
H-E Parts International Pty Ltd, Mackay
NQCranes removes the crane from the dragline and transports to our Mackay workshop. An assessment is given of the hoist and crane prior to stripping. We then remove the hoist off beam, rope guide and rope and conduct a complete run test of equipment and parts. NQCranes overhauls or replaces all necessary parts, fits the crane with an NQCranes electronic latch system and repaints the crane including updated signage. After in-house load testing and calibration, NQCranes transports the crane back to site and reinstalls into the dragline.
Overhauls are organised months in advance with our mining customers, to suit upcoming scheduled shutdown work. This reduces crane downtime and ensures project reliability during major dragline shutdowns between NQCranes and our customer.

H-E Parts International, Mackay required two underslung cranes and runway system to suit their existing building.

Stresscrete Precast & Prestressed Concrete, Rockhampton
Stanwell Corporation required a complete refurbishment on five monorail beams (3x 250kg & 2x 2T) within the Barron Gorge Hydroelectric power station, Cairns. NQCranes removed the existing monorails from site and completed the structural modifications required for refurbishment. We also completed a visual inspection, NDT, blast and paint. The main 1.6T Monorail was replaced with a new monorail with an increased capacity of 2T. The location of this monorail was changed to assist with removal of key components for future overhauls. All monorails were reinstalled, load test and commissioned to the Australian Standards.
