In 1981, a small engineering company from Perth, Australia created something Caterpillar couldn't ignore - the Tiger 690 Wheel Dozer. Built from converted Cat 992C wheel loaders, this 90-tonne beast became the world's largest mechanical drive wheel dozer and eventually forced Caterpillar to acquire the design outright.
This documentary explores the complete history of the Tiger 690, from its origins at BHP Iron Ore's Mount Whaleback mine to its evolution through the 690A, 690B, and 690D models, and finally its transformation into Caterpillar's own 854G and 844 wheel dozers.
