Maintenance

A massive toolbox is hoisted 100 meters up to the gondola of the windturbine.
I was wondering how they would get it inside and was expecting a hatch on top would open just as at the older windturbines but there is a hatch at the downward side...

Downstairs two men were waiting, accompanied by a dog...
Dog?? Yes, and it was patiently waiting until the work was done....
