To extract precious metals found beneath the earth requires a massive 232-ton, two-story-tall dump truck with a load capacity of 320 tons — a giant earth-mover like the Komatsu 930E. This amazing engineering achievement is made possible by five essential raw ingredients: coal, chromium, mineral oil, latex rubber and sulphuric acid, an electron superhighway that generates massive power.

The highway truck — a modern workhorse, a heavy hauler vital to commerce — carries an 80,000-pound payload and must operate in every condition from sub-zero cold to triple-digit heat. To survive, it must be strong, durable and fuel-efficient, like the Mack Pinnacle, an engineering achievement made possible by platinum, petroleum, copper, manganese and polyurethane.
