A $4.5 million Motor Generator or ‘MG’ was flown into Ensham Coal mine in a bid to repair the $100 million dragline at the site.
A Russian Antonov 124 aircraft, originally designed as a military jet, was responsible for flying in the MG.
It is the second time this month that the aircraft has flown into Brisbane with parts for Ensham’s 3000 tonne Bucyrus 8050 dragline which was trapped when floodwaters overwhelmed half the mine’s operating pits in January this year.
The giant machine spent more than three months submerged in a flooded coal pit, before being walked out of the mine for repairs last May using borrowed propel motors and external power supplied by another dragline.
The Motor Generator Set is one of two which power the machine’s moving functions through electric drive motors controlling hoist, drag, swing and propel functions.
Ensham CFO John Seedhouse said production of the MG set normally take 52 weeks, but was completed in only 28 weeks to help the mine with its recovery operation.
According to Seedhouse, it was necessary to use air freight to meet the mine recovery schedule so that Ensham could resume normal production as soon as possible and meet the needs of its customers.
“We are very grateful to the terrific job done in producing this vital component and the efforts of the team of people we have repairing the dragline,” he said.
“The repairs of the machine are all on schedule and we hope to have the machine working in the mine again by December.”
