While the Bucyrus RH400 was the one to make its star turn in Transformers 2, the 31-million-pound Bagger 293 might have been the machine better suited for the role of villain in a sci-fi summer blockbuster. This bucket-wheel excavator, the Guinness World Record-holder for largest land vehicle, cuts an intimidating figure at a towering 310-feet tall and 722-feet long.
When Caterpillar introduced the 797B in 2002, it entered its class as one of the largest dump trucks in the world; six years later, Caterpillar upped the ante with its 797F besting its predecessor in both payload capacity and horsepower. The 797F sports a 20-cylinder, 4000-horsepower, single-block engine, which bests the 797B by 450 horsepower. Caterpillar's massive truck also hauls 20 tons more than its earlier incarnation, moving it into the rarefied air of trucks with a 400-ton payload.photo credit: Caterpillar
As other machines dig and move the material around, mobile crushers make the rubble easier to handle and transport away from a site. One of the largest mobile crushers on the market is Metso's Lokotrak LT160, which can crush up to 1550 tons per hour of rock or concrete and can handle one-cubic-meter-sized boulder. Metso designed the machine with tank-like tracks so it could more easily traverse the rough terrain in quarries and mines, moving around a site to where it's most needed. The nearly 64-foot-long, 11.5-foot-wide, 12.5-foot-tall LT160 has a 27 cubic yard hopper that feeds into a v-shaped jaw crusher that uses a moving plate that pulverizes rock and concrete against a stationary one, with pieces falling to a conveyor below once the pieces are small enough. With the material now broken down, it makes it easier for trucks like the Caterpillar 797F to haul it away from the site.

The world's largest rubber-tired front-end loader in the world scoops and moves earth with a staggering 53-cubic-yard shovel that as John Pearley Huffman previously wrote for Popular Mechanics, could easily hold two Cadillac Fleetwoods piled on top of each other. A 65-liter, 2300-horsepower diesel engine drives the nearly 67-foot-long and 21-foot-high behemoth can load lift upwards of 72 tons of material almost 44 feet in the air, filling the largest trucks in just a few passes.
