The CRAZIEST Mining Shovel Prototype Ever

In 1983, while Caterpillar was still years away from entering the mining excavator market, a consortium of Japanese industrial giants quietly built one of the largest hydraulic mining shovels of its era. The SMEC 4500 weighed 463 tonnes, produced 2,400 horsepower, and worked in Australian mines loading massive haul trucks. Then it vanished from history.

This is the story of a forgotten machine that predated Caterpillar's first mining excavators by nearly a decade.
