Putting together a really big CAT

The Cat® 797 Mining Truck redefines 'big'.

Weighing in at more than one million pounds, the latest offering from Caterpillar has a payload capacity of 400 tons. The engine displacement is nearly 6,500 cubic inches, producing a massive 4,000 horsepower.

So, how does Cat build its 797 Mining Truck?  In the same way as any vehicle - one piece  at a time!  However, because it takes such a long time, the company has created a three minute timelapse video to impress potential customers.
