Tell us how you repair equipment? What crane do you use?

 Dear Colleagues, Experts and Friends
We calculate the approximate height of the building in this way. The whole building needs to be heated in the winter. The height of the building depends on the overhead crane. You need to lift the largest equipment. There should be a clearance of 0.5 meters. Plus the roof.
In Chile, Peru, USA, Mexico they don't build buildings, they don't heat them.
