Weight of Light Tower

Weight of Light Tower

Weight of Light Tower

(OP)
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?

You may have additional chance for a good response if you ask this question in the Transmission Structure Engineering section of this forum.

It is possible that the tower manufacturer may have basic rigging recommendations for their products.
  

RE: 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?
