Check out this large crankshaft,


This is the crankshaft for a Wärtsilä-Sulzer RTA96-C engine, the largest reciprocating engine in the world, used in large container ships. It's a 1810-liter engine that generates 108,920 horsepower at 102 RPM, and it idles at 22 RPM... almost 3 seconds per rotation. This crankshaft weighs 300 tons (660,000 pounds) and each piston weighs 12,000 pounds and has a stroke length is 8.2 feet.

As of 2006 there were more than 300 of these engines in active service.
