World's Biggest Truck

This gargantuan of a truck is hard to describe, but put it this way, imagine standing on the terrace of your duplex house and driving the entire building down the road.

The biggest truck in the world is neither a Volvo nor a Ford, not even a Mack truck with a double trailer. The real monsters are mining trucks that stand more than 21 feet tall and 48 ft long.

Caterpillar 797F Mining Truck, which weighs more than one million pounds (453,592 kilograms) and can carry and dump more than 300 tons of material in the back. These mining trucks produce about 4,000 horsepower to move all that mass and travel at a maximum speed of 67 kmph.
