Yes, impressive.
The Terex Titan is powered a 16 cylinder locomotive engine, and delivers 3300 horsepower. It was combined with a huge generator to deliver power to 4 traction engines located on the real wheels. The generator alone has enough power to supply 250 homes with electricity.
Specifications:
Height: 6.9 m (22.5 ft) With Box Raised: 17.1 m (56 ft)
Length: 20.1 m (66 ft) Width: 7.6 m (25 ft)
Weight: 260 tons Payload: 350 tons
Max Weight: 610 tons Horse Power: 3300
The tires are 11.5 ft in diameter, and weigh 4 tons each. Two Greyhound buses and two pick-up trucks would fit inside its dumper.
I used to work at a rock quarry that had 85 ton Terex haul trucks.
I got to see up-close a 350 ton Liebherr.
These things are beyond belief, they are so big they defy description.

The statistics give the hard cold picture -

I used to work for a guy that ran this.
Big Brutus could fill the Titan in only 3 dipper loads.
I have been on this shovel, it is HUGE!!!
