We have used our extensive knowledge of the mining industry, of stress monitoring, materials and equipment engineering to develop DuraCluster, to extend life and reduce repair costs of operational draglines.
This, and improved design modification and repair scheme, dramatically improves the fatigue performance on existing draglines with tubular boom designs.
The draglines, so essential to many mining operations, experience stresses at joints that can result in endemic fatigue and cracking. With a boom replacement costing $20 million and three months’ downtime, repair costs become unsustainable. These are the issues that led us to create DuraCluster, dramatically improving performance on existing tubular-boom draglines.
STAGE 1: Attach engineered bracing to maintain geometry.
STAGE 2: Remove lacing member ends adjacent to the main chord, repair surface of main chord to pass 100% UT inspection.
STAGE 3: Prepare lacing ends and main chord surface for welding.
STAGE 4: Weld new members
STAGE 5: Complete post weld actions, apply corrosion protection coatings.
With DuraCluster offering the highest levels of lifecycle support and optimization of removal capacity at the lowest cost per tonne, our dragline design scheme is one of the industry’s most sustainable mining solutions.
