Caterpillar dealer Hastings Deering has recently completed a full component change out on five of New Hope Group’s Cat 793F haul trucks working at the New Acland coal mine in Queensland, Australia.
The miner used the local Hastings Deering workshop in Toowoomba, Queensland, for the six-month undertaking, New Hope said.
“At A$2.2 million ($1.6 million) per truck, it sounds an expensive exercise but, with each truck costing almost A$5.5 million new, it was worth the expense,” New Hope said.
New Acland Maintenance Supervisor, Rob Trapp, said it was the first time the company had sent an entire fleet to the Toowoomba workshop.
“The guys and Hastings Deering have done work for us before, but this was by far the biggest job they have done for us,” he said. “It was a huge job, replacing basically every component on the truck. The fleet is only six years old but each had done about 24,000 h of work at the New Acland site. That’s slightly above industry standard so they were due for a tune-up.”
Service Manager at Hastings Deering Toowoomba, Justin Butcher, said: “This was a great win for us. We have around 100 workers at the Toowoomba Service centre and, of that, about 12 worked on this project basically around the clock.
“Each truck took three weeks and we had a week break in between each truck. We did what is known as a certified power train rebuild, which means we effectively stripped the trucks bare and replaced all the drive train components including the engine.
“In fact, apart from the cabin, tray and tyres, there isn’t much we didn’t either remove or replace.”
To get the 170 t trucks from Acland to Toowoomba, the company took off the cab, tray and wheels and loaded it into another big truck, according to Trapp.
