The cutting machine was also a Liebherr; a LC 2000 gear cutting machine for cutting 2m diameter gears, within tolerences of a few thousandths of a millimetre.
The crane lifted the components into place while between over a dozen gear machining units.
Operators assembling the gear-cutting machine raised a 4.2t cutter head into position on the main column.
They then lifted a 20t counter column onto the machine bed on a high-precision guide track with exceptional accuracy.
