Mining Workhorses – The Top Contenders

They are the behemoths of the mining landscape and each year the major players manage to make them bigger, faster, more operationally efficient and even more comfortable. In 2020 the biggest beasts come from the giants in the field – Belaz, Caterpillar, Liebherr, Terex (re-branded as Bucyrus) and Komatsu all with dump trucks jockeying for position.

1. The Belaz 75710 with a staggering 496 tonnes payload, is easily the world’s biggest dump truck – and the thirstiest, guzzling around 1300 litres of fuel per 100 kilometres. At 20.6 metres long, 8.16 metres high and almost 10 metres wide, the 75710 is 360t unladen. Featuring eight Michelin tubeless pneumatic tyres it also boasts two 16-cylinder turbocharged diesel engines, each with an output of 2,300hp producing a top speed of 64kms per hour.

2. While the Belaz 75710 was designed for the Russian landscape, the third generation Caterpillar 797F is a familiar site around Australian mines. With a payload of up to 400tonnes and a maximum speed of 68 kph from its 20-cylinder diesel engine, the 797F features Cat’s unique hydraulic torque converter transmission which sets it apart from competitors’ diesel-electric transmission.

3.     Also carrying 400tonnes, the lighter weight ultra-class duo from Liebherr, the T 282C and T 284 Dump Trucks are also powered by a 20-cylinder engine. Liebherr claims that this combination of lighter weight and 4000hp adds to the capability and flexibility of these trucks.

4.     In addition to a 360tonne payload, 20-cylinder four-stroke diesel engine and top speed of 64klms per hour, the Terex / Bucyrus MT6300AC Dump Truck boasts bed-heating technology making it perfect for cold climate mining.

5.     Finally, back to the Belarusian Belaz. Their 75601 model is specially designed for varying climatic conditions and shifting loose rock on haul roads at deep open-pit mines. The payload of 360 tonnes is carried by a 20-cylinder, four-stroke V engine achieving speeds of 64klms per hour.

At up to $7 million, these are vehicles that need to pull their weight to pay their way.
