That's interesting. I never had anything to do with the automation / remote control of the mining gear or the railways. But I often wondered who owned the "rights" to the control systems for the crushing plant. The actual DCS that we (HWE / Leighton) installed to control the plant was Citect - but the interface between Citect and the operator control panels in Perth was I believe a Rio Tinto "in-house" system.Quote:

My understanding is that these trucks do exist but so far only a couple of prototypes. They are based on the same chassis as the Russian Missile Carriers. I was also informed that there was one - only a single in Australia on trial at present, but the cost involved on setting up a 5 unit system was upwards of $30 million, though with both Cat and Komatsu proposing no more sales of trucks to companies but hire based on a % of commodity prices could get real interesting.
Arthur, the prime movers and power trailers generally have 600 horsepower Cummins engines, matched to Allison automatic transmissions.Quote:

I have seen other applications using a prime mover and two power trailers - total of 1,800 horsepower. I am not sure whether this is the maximum that they can run in a single consist. The biggest of these that I have seen consisted of prime mover and 7 trailers at The Granites Gold Mine in the NT - but pretty sure that these had no more than two power trailers in each road train.

With them tied together you've got work-flow issues (no truck can leave until they're all full), movement issues (huge turning circle compared to a rigid truck) and any material dropped between the trucks while loading becomes a big problem.
