Have a ring round machinery movers. many have fork trucks made for doing this, they are very big on capacity but can only lift 3 or 4 feet so they only need low masts to get into low buildings.

When i bought my big CNC from an auction I used the company who were already there doing work to save money.
they had one of these trucks and because my machine was blocked in by a 15 ton boring machine whey just drove in, picked the borer up, moved it to one side, then went back and picked my 3 tonne mill up and moved it outside.
took all of 15 minutes to do all this.
