Seven of the top ten longwall coal producers use Electras. According to the latest Joint Coal Board report, Electra shearers have produced 148 million tonnes since their initial market introduction in 1992.
In 1999, Long-Airdox Electra Models EL 1000 and EL3000, combined with earlier Model AM500 shearers, delivered 59% of Australia’s total annual longwall coal production, reported the JCB.
