  1. The photo looks like the innerjib hooked to the tower and the connection looks rather flimsy. It will need to come down. We had a crane hit by a hurricane/tornado some years ago and bent it all up. Was still standing but taking it down was a mess. Structures that the crane was in use to build had crowded the base area and getting as close as when it was first assembled was impossible. A bigger pick crane was required. The pins and tower bolts were squeezed in place from the bending pinching the pins. Driving them out was time consuming, From the ground you could see the tower out of plumb and some bolts pinning the base plates to the concrete had pulled out. Some of the crane crew did not want to go topside-not safe. We got it down ok but took more time than putting it up.
