Picture the rim of a Siberian open pit mine at dawn.<\/p>\n
The hole below is so wide you could drop a small town into it.<\/p>\n
Down on the floor, one yellow machine crawls toward the loading site.<\/p>\n
It is the size of a three story building set on wheels.<\/p>\n
Most people who see it never guess what it can do<\/strong>.<\/p>\n And almost no one guesses how it moves<\/strong>.<\/p>\n The truck is a BelAZ 75710, built in Belarus.<\/p>\n It is the largest and heaviest mining haul truck ever made.<\/p>\n Empty, it already weighs about 360 tons.<\/p>\n Load it up, and the whole machine tips the scales at 810 tons.<\/p>\n Its payload alone is a staggering 450 tons of rock.<\/p>\n That is roughly the weight of 300 ordinary cars in a single load.<\/p>\n A truck this size can never legally drive on a public road.<\/p>\n So it is shipped in pieces and bolted together at the mine.<\/p>\n It stands more than twenty feet tall at the top of its box.<\/p>\n Nothing about it fits the scale of a normal road.<\/p>\n And all of it answers to a single driver<\/strong>, perched high in one cab<\/strong>.<\/p>\n Look first at the wheels, and the scale hits you.<\/p>\n The truck rolls on eight massive tires.<\/p>\n Each one stands taller than a grown adult.<\/p>\n A single tire can carry about 100 tons of that load.<\/p>\n That is close to the weight of seventeen African elephants.<\/p>\n The rubber alone in one tire weighs several tons.<\/p>\n Two people could stand side by side inside a single tread.<\/p>\n These tires are custom built and brutally expensive.<\/p>\n Each one costs well over fifty thousand dollars.<\/p>\n A full set of eight runs into the hundreds of thousands.<\/p>\n Rough haul roads chew through them fast.<\/p>\n Every mine budgets for replacing them again and again.<\/p>\n Just keeping the truck rolling is a fortune in rubber<\/strong>, spent again and again<\/strong>.<\/p>\n Everything about this machine runs to extremes.<\/p>\n Its two diesel engines together make around 4,600 horsepower.<\/p>\n They can drink well over a thousand liters of fuel an hour.<\/p>\n Yet the loaded truck still tops out near 40 miles per hour.<\/p>\n It sips almost nothing when idling, then gulps under a full load.<\/p>\n A single shift can burn through a small tanker of fuel.<\/p>\n Its brakes throw off enough heat to warm a house.<\/p>\n It is built to work in brutal cold and blistering heat alike.<\/p>\n Temperatures far below freezing to well above it are no problem.<\/p>\n The whole thing is engineered to run almost without a break.<\/p>\n Everything is oversized to survive the constant punishment.<\/p>\n But the strangest part is not the size or the fuel.<\/p>\n It is the way the power reaches the wheels<\/strong>, or rather, how it does not<\/strong>.<\/p>\n Here is the hidden system almost no one pictures.<\/p>\n A machine this heavy has no mechanical gearbox turning its wheels.<\/p>\n According to one report<\/a>, its two diesel engines never touch the wheels at all.<\/p>\n Instead, each engine spins a large electric generator.<\/p>\n That electricity flows to four huge motors, one at each wheel.<\/p>\n Every motor puts out around 1,200 kilowatts of power.<\/p>\n There are no gears to shift and no clutch to slip.<\/p>\n Electric motors deliver their full force from a dead stop.<\/p>\n That is exactly what a loaded giant needs on a steep haul.<\/p>\n It is the same trick that moves a diesel electric train.<\/p>\n So the giant is really a rolling power plant<\/strong>.<\/p>\n Diesel makes the current, and electricity turns the wheels below<\/strong>.<\/p>\n Trucks like this move the rock that builds the modern world.<\/p>\n They haul the coal, copper, and iron that everything depends on.<\/p>\n The diesel electric design is now spreading across the industry.<\/p>\n It lets engineers push machines to sizes a gearbox could never handle.<\/p>\n According to one account<\/a>, the same electric drive powers many of the biggest haulers on Earth.<\/p>\n Newer versions are even learning to drive themselves.<\/p>\n Some big mines already run these giants with no one aboard.<\/p>\n The same drive to build at colossal scale reshapes the land, and life slips back in, from a solar farm<\/a> fox to the seals near an offshore wind farm<\/a>.<\/p>\n A driver who has piloted 810 tons never forgets the feeling.<\/p>\n The cab sits so high the world looks small below.<\/p>\n One truck can slowly move an entire mountain over its working life.<\/p>\n Stand at the rim and watch the giant crawl below.<\/p>\n It is one of the most electric machines you will ever see<\/strong>, hiding in plain sight<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":" Picture the rim of a Siberian open pit mine at dawn.
