From Rusted to Ready: TW Woods Delivers 777 Water Cart Refurbishment for Westrac
TW Woods Construction has successfully completed a full refurbishment of a 777 Water Cart for Westrac Tomago, showcasing our end-to-end capability in heavy equipment repair, abrasive blasting, lineboring, and protective coatings.
From initial assessment through to final coating, every step was carefully managed by our in-house team to return the unit to near-new condition ready for service on a demanding mine site.
Stage One: Assessment and Quoting
It all began on site at Westrac’s Tomago facility, where TW Woods’ Blasting and Painting Manager David Croul carried out a full inspection and quote. From there, the job was scheduled, and on 28 September 2021, the 777 Water Cart arrived at our Tomago facility.
Stage Two: Abrasive Blasting and NDT
The unit was moved to our dedicated blast shed, where internal surfaces were carefully sandblasted to allow for non-destructive testing (NDT). This crucial process exposed any cracks or defects in the welds and baffles ensuring that repairs were carried out accurately and to the highest standard.
Stage Three: Weld Repairs, Lineboring and Precision Prep
Following NDT, our fabrication team repaired all identified cracks and damage. The lineboring and pin sections were then completed, restoring alignment and function to the critical mechanical connection points.
With assistance from Wheeler Cranes, the Water Cart was then flipped onto its side to allow for better access during final blasting and Rhino Lining application. This attention to access and surface prep helps ensure a more durable, longer-lasting finish.
Stage Four: Painting and Final Coatings
After blasting was completed, the Water Cart moved into our industrial paint shed, where external surfaces were primed and internal surfaces were treated with a robust two-coat protective system. The unit was then returned to its upright position, allowing us to complete final coats of Westrac yellow on the exterior.
Back to Work — Better Than Ever
By 14 October 2021, the fully refurbished 777 Water Cart was loaded and returned to Westrac Tomago looking brand new and ready for operation on its assigned mine site.
At TW Woods, this project is a perfect example of our in-house ability to handle large-scale refurbishment work from inspection and welding to blasting, painting, and delivery.
We can do that.
