Had a couple of pics from work on my phone, mightnt be much interest in them uo i said id throw them up anyway!
This one is of a 500 tonne liebherr crane installing the 55 tonne generator
This one is of two 250 tonne cranes being used to change damaged blades. Note the deflection in the boom in both pictures, modern cranes are designed to do this so they can use a lightweight and strong steel when manufacturing the boom.
