After tower crane is installed immediately before it's put into operation there are several checks needed to be done:

2. Visual inspection of cracks.

A licensed inspector must check the cracks in the tower crane, this check is done by a special spray especially on the steel connections of the tower crane. If there are some cracks in the connections, it must be repaired by a specialist welding worker. After repairing the cracks the inspector may check again to give approval.

It's better and much easier to do the first check before installation
