In 2014, Belarusian engineers created the best dump truck in the world. Why is he so good?
It is very big
The height of the new BelAZ is 8.1 m (with a 3-storey building), the width is 9.8 m, and the length is 20.5 m. That’s really “wow”!

He lifts the most
Mining excavators appeared in the early 30s of the last century. Even then, they were better than trucks – they coped better in difficult terrain, had a bucket body with a protective visor for the driver and took on board much more cargo.
Today, several brands compete in the dump truck market at once – Caterpillar, Liebherr, Terex, Euclid, Hitachi, Komatsu and BelAZ. But three years ago Belarusians bypassed everyone at once. On January 22, 2014 BelAZ-75710 “lifted” a load of 503 tons and 505 kg, which is 140 kg more than the previous record.

He has the coolest wheels in the world.
The new BelAZ is equipped with special Bridgestone Titan tires. Each of them weighs 5,300 kg, has a height of 4 meters (size 59 / 80R63), is capable of accepting a weight of 101.6 tons and costs $ 42.5 thousand. There are 8 wheels in total, so we get a total load of 812.8 tons.
We must immediately subtract the weight of the dump truck itself from this number – 360 tons. The result is 450 tons – exactly as much BelAZ-75710 can take on board according to the project. “But what about the record of 503.5 tons?”, You ask? Yes, you understood everything correctly – this is an excess. But after all, everyone loves records, and besides, which of our vehicles has at least once traveled without overload, eh? :).

He has a great appetite
Two BelAZ-75710 gas tanks are designed for 5,600 liters. A full gas tank at a regular gas station would cost about 250,000 rubles! But you also need a cooler (under 900 liters) and engine oil (538 liters). Fuel consumption, too, as it calls, “corresponds” – for 100 kilometers, 1,300 liters are required.

He warms himself
Part of the exhaust gases is spent on heating the cargo – BelAZ often have to work in the harsh Russian winter, and this measure is simply necessary so that 450 tons of ore does not freeze in the back and do not have to be beaten off (manually, hehe).

He’s a sedate guy
The maximum speed of the new BelAZ is not high – only 64 kilometers per hour. But this giant is able to conquer mountains with a slope of up to 18 percent and turn around on a “patch” with a radius of 20 meters. How do you manage to maneuver so cleverly? It’s simple – both axles of the dump truck rotate.

He has a big heart
The new BelAZ has a hybrid engine – 4 Siemens electric motors powered by two Russian-made diesel generators of 2,300 horsepower each. One diesel engine is enough for an empty dump truck, but a loaded one already needs each of the available “horses”. 16-cylinder engines weigh 60,000 kilograms each, their length is 9.5 m, width is 2.8 m, height is 3.9 m.
If they are removed from the car, then the vacated space will be enough for a compact residence of several people. And if you also “populate” the body of the dump truck, then there will be a place for a small personal plot, and for not the smallest country house.

It costs money – big money
Three BelAZ-75710s are assembled at the plant per month, and each of them, depending on the configuration, costs from 8 to 9 million dollars.
