There's no simple fix for the Mega Mechanics and it's out with the old and in with the new. The installation of a new 10 million dollar jet engine in an A330 aircraft sees an intricate support and bracing technique used, while work on a 550 tonne excavator means 24 hours of preparation all comes down to an install that must happen within just seconds. It's dirty work changing the mud filter at the sugar mill and a coal handling vibro-gate causes trouble in Newcastle.
