According to Mining News Pro - The biggest rigid dump trucks or haul trucks are off-highway vehicles that are primarily used for the transportation of mined materials and at heavy-duty construction sites, quarries and mines. The dump trucks are constantly being manufactured bigger in size as there is a demand for larger payload capacities. Due to the fact that haul trucks are so large and able to transport a huge amount of material, the customers often prioritise to use only one large dump truck rather than a whole fleet of smaller trucks which is more economical.
1. BelAZ 75710
The winner of our ranking of the Top 10 largest mining dump trucks is BelAZ 75710 that comes from Belarus. The behemoth has a nominal payload of 450 metric tonnes, which is almost 500 short tons! The Belarusian manufacturer introduced the 75710 in 2013 and delivered the first machine to a coal mining area in Kuznetsk Basin, Siberia. The overall size of this giant is pretty astonishing: 20.6 m length, 8.17 m height and 10.6 m width. Furthermore, imagine that the driver is sitting 7 metres above the road. Even though standard mining trucks use 6 tires, the 75710 hauler is equipped with 8 tires that symmetrically distribute the weight.
The largest dump truck in the world weighs 810 tonnes and provides a heaped body capacity of 268 m³. Nevertheless, two 16-cylinder engines with a total gross power of 3430 kW (4600 HP) are able to run the truck 64 km/h. This is approximately the same power as five Formula 1 cars. Belarus seems to be pretty proud of BelAZ 75710 as the giant quarry truck was featured on a Belarusian stamp, highlighting the popularity of the largest dump truck in the world. And what about the price? Well, if you would like to own one of the biggest machines ever built, have a pack of $6 million ready.
