BHP posts second straight year of record iron ore production, beats estimates
The world's largest listed miner said iron ore output from Western Australia on a 100% basis was 76.8 million tonnes in the three months to June 30.
Watch this documentary about two of the biggest draglines ever built.
The Captain was the first of the big draglines, built by Marion Power Shovel for the Captain Mine in Illinois. It was then rivalled by the Big Muskie, owned by the Central Ohio Coal Company.
Big Muskie operated from the ’60s to the ’90s, and was retired when the operating cost became too expensive.
The Captain quit operating after suffering fire damage, and repairs proved too costly.

Two awesome machines! However, the Captain was a stripping shovel, not a dragline.
