4D-Delta was asked by our client to help them with a fabrication project for a mining major in the Pilbara region of Western Australia. Our client was required to fabricate a chute to replace an existing chute on-site that was coming to end of service life. The new chute had to be built off-site and trucked to the mine, where it was critical that the new chute fit to the existing infrastructure without modification. Any delays in fitting the fabricated chute would affect production, and our client's reputation.
Our client only had one shot of getting this right and decided to use 3D laser scanning to measure-up the old chute rather than the traditional tape and caliper. The chute was taken out of service and placed in a yard for 4D-Delta to perform the scans. Numerous scans were taken to get full coverage of the chute's internal and external surfaces including flanges, stiffeners, hinges and and stud locations.
From all of the scans 4D-Delta produced a single point cloud aligned to the chute centreline. The point cloud was used to create a complete 3D CAD model and fabrication drawings, which the client then used to fabricate a new chute.
The chute was fitted at the end of March 2015 without a hitch and needless to say that 4D-Delta's client was very happy, and of the course the mining major!
