Depends on the size of the building, im pretty sure the video i saw on youtube of a one in toronto that had to be 40 storeys, the mobile crane reached all the way to the top, there must be different mobile cranes that do certain sizes of buildings. Also, i do know that when they do jack up cranes, prior to taking them down, they sometimes will just take portions down from the jacking rig so the mobile crane can reach it easier.
the Alt hotel crane here had that process, i saw it get shorter until the mobile crane got ahold of it. We have a crane coming down today or soonish and the guys were lifting the rig up to the top yesterday, im assuming they will take a couple sections out then take the jib arm, etc.. with 300 main they could this process, or if theres enough space and if they the right mobile crane, they could reach up the the 40 storeys.
only one way to tell.
