When massive , open - Hell mines like theMinera Escondida — in Chile ’s Atacama Desert — need to rend millions of long ton of minerals out of the footing each year , they trust on fleet of huge , “ extremist - Class ” haul truck . The ETF Haul Train , however , pulls four time the minerals of these Harlan Fiske Stone - toting giant with just one driver .
Haul truck are not like the typical dump trucks that you see in urban construction sites . They are particularly designed for the rigors of in high spirits - product mining , with multiple axles and reinforced frame . This class of truck is capable of move loads anywhere from 50 to 400 tons ( compared to 35 - 100 long ton for a standard prey truck ) , the large of which is know as the “ Ultra Class . ” The vast memory capacity that makes these vehicles so valuable also makes them hard to manoeuvre , requiring particularly trained driver to operate , and all-encompassing roads to repulse on .
So rather than just make a bigger mining hand truck , European Truck Factory of Germany build a wise one . exchange traded fund mining motortruck can tote anywhere from 170 - 400 tons individually , bet on the model , spreading the system of weights out over as many as seven axle with four tyre per axle . A “ Central Tyre Inflation System ” actively monitors and adjust the atmospheric pressure within each wheel as the ground surface change — lowering the pressure level for travelling over mild ground and re - inflating as the background firm . If a tire goes savourless , which would directly sideline most draw trucks out of fear for axle damage , the ETF mining truck will automatically grow that axle and alert the driver but still be able to finish his run . What ’s more , these trucks are both all - bike - drive and all - cycle - steering , which greatly reduces the necessary turning wheel spoke .
The ETF ’s most impressive feature article , however , is that multiple trucks can be linked together into a individual , unified Haul Train operated by a single driver . Each motortruck in the train is connected via a blade arm not only physically links them but also carries restraint information — accelerator , pasture brake , and steering input — from the lead hand truck so that no matter how many are connected , they operate in unison . This allows a unmarried driver to haul as much as 1520 US loads of material — per trip-up . The Earth will be dig out in no time . [ Wikipedia – ETF Trucks1,2 ]
