Krupp Bagger 288

To put it lightly, World's Largest Trencher, the Bagger 288 is a bucket-wheel excavator. But there's nothing light about a 13,500-ton mobile strip miner. The German creation is 721 feet long, 315 feet high, and can clear an area the size of a football field three stories deep - in just one day.

The Liebherr LTM 11200-9.1 telescopic crane is ridiculous. It can lift up to 1,200 tons. It's boom extends to 100 meters long with up to 126 meters of additional lattice. Rolling along on a nine-axle suspension, this bad boy can handle any job. Disc brakes come standard.

The world's largest rubber-tire front loading vehicle of its kind, the L-2350's bucket is roughly the size of a studio apartment. It has a 2,300 horsepower engine capable of lifting up to 160,000 lbs. The operator stands two stories off the ground, and the mammoth bucket extends to a maximum height of nearly 44 feet.

Quite possibly the largest demolition shear in the world, the Genesis 2500 wields devastating power, especially mounted on the Rusch excavator. It is a destruction machine with Godzilla-like force.

Its nickname is Doobi (Hebrew for teddy bear) but this heavily armored bulldozer is anything but soft and cuddly. With 15 tons of Israeli-engineered armor protecting the entire machine and bulletproof windows sealing in the cabin, this monster machine is equipped for construction, rescue, demolition, and even defending itself with custom-fitted grenade launchers and machine guns.
