“When I started out in mining, everybody was running 100,000-hour trucks. Then the adage came along that you only need a 60,000-hour fleet, because after 10 years of fleet life, technology changes and your product becomes less efficient. Therefore, the thinking was that you should roll fleets over every 10 years so that you can introduce new technology. Now everybody is talking about life extension, rebuilds, reconditioning and new unit sales. The expectation is that your major mobile equipment assets are expected to last longer, and companies want 80-100,000 hours or beyond.”
