Monster trucks, super dozers and gigantic cranes are eye-popping engineering feats that are found on jobsites all over the world.

Here’s a look at some of the biggest, bulkiest and most powerful mining and construction machines ever made.

The world’s most powerful crawler crane can hoist the equivalent of 30 blue whales, or 3000 tons, in one load. Fully extended, the LR 13000 is taller than the Carlton Centre in Johannesburg. Its main boom is the length of one and half football fields, and the hook block weighs 11 tons – that’s about six times the weight of an average family sedan!

The Cat 797F is the second biggest haul truck in the world. It has a payload capacity of 400 tons, and is so big it has to be transported in separate components and assembled at the job site. It’s longer than two double decker buses, and more than nine metres wide. Each of the truck’s six mega-tyres weighs 5300 kg – that’s two and half times more than the weight of a fully-grown rhinoceros.

With a load capacity of up to 92 tons per pass, the Liebherr 9800 is the most productive excavating tool available today. It is also one of the largest. The machine weighs 810 tons – that’s nine times the weight of the Endeavour Space Shuttle – and has a shovel or bucket capacity of 42 or 47 cubic metres, respectively. An engine capacity of 2984 kW is four times that of an F1 racing car.

Weighing in at 272 tons, the L-2350 wheel loader is a beast of a mining machine. Its massive shovel is capable of loading 80 tons of material in one pass. It boasts a 7-metre lift height and 3,5-metre reach and, with a 16-cylinder 65 litre turbocharged engine pumping out 1715 kW, the loader is officially the largest, and one of the most powerful, earth moving machines in operation.

With a weight equal to that of 100 fully grown elephants, the BelAZ 75710 is by far the largest and heaviest dump truck in the world. It can carry a 450-ton load and is powered by two 16-cylinder turbocharged engines capable of delivering 24 times more torque than the average F1 racing car. The chassis is as long as two double decker busses, and the truck has eight 4-metre high wheels to keep it off the ground!

Custom engineered to bore a tunnel under the city of Seattle, the Hitachi Zosen tunnel boring machine was the largest machine of its kind. It was 99 metres long, weighed 6100 tons and cost $80 million to build. The cutterhead had a 17,5-metre diameter and, due its vast size, the machine was shipped to the USA in sections and assembled onsite.

It weighs 152 000 kg and has a ‘standard’ blade that’s more than seven metres wide and three metres high. It can move 69 cubic metres of material per pass – that’s the equivalent drum volume of six and half concrete mixing trucks!
