I am a geotechnical engineer so this area is way new to me. Can you tell me roughly what the weight of a 120 ft tall 4 legged light tower might be? We have to hoist it with a crane and set it down because we are digging next to it. Are they strong enough to grab say 2/3 of the way up and then set it down?

Weight of Light Tower

Are you trying to use the crane as a temporary foundation for the tower so that you can install a new foundation after you do your digging? If so, you would have to account for the weight of wires, wind loading and so forth and that may necessitate 2 cranes, one on each side of the tower.
Cranes are not necessarily built for resisting wind an so forth. What might be necessary is to build 2 scaffold towers with a beam that passes through the tower and then use screw jacks and hydraulic jacks to lift the tower the few inches that it takes to replace the foundation.
Is there a wat to relocate your digging or to do directional drilling instead of temporary support for the tower?
