Big – Presented By Caterpillar

Wherever there’s mining, you’ll find Caterpillar. From underground coal mines in China to surface gold mines in Mali to the oil sands of Canada, Caterpillar products are at work around the world – drilling and digging, loading and hauling, grading and dozing. And most of them aren’t just BIG – they’re huge!
