The largest crane I have seen sent to a tree job is 120ton, and those take 2-3 hours to set up and break down. Cranes generally breakdown into sections 8ft wide and under 40 ft long. Most tree work is done with cranes under 90 ton capacity. More likely the problem is safely cutting the tree into pieces small enough for the equipment to move. Also the largest chainsaw bars are rare in the east (88 inches?).
I have seen logs so large that only one could fit on the log truck (weight), we placed that one in with the crane. Do you know if there are any foreign objects in the tree? E.G. metal, concrete, masonry, ropes, etc.
I have no idea whether there were foreign objects. The tree took down two poles and is resting on the wires, as far as I know.
