Pionsinho has found the key to the legality of the crane. Check this out....(and thanks Pionsinho)

It is in the FIA FORMULA ONE WORLD CHAMPIONSHIP
Regulations, on Appendix H to the Int. Sporting Code in the chapter III.

6.1 If a car stops
If a car stops on the course, or leaves the track, the first duty of the course marshals in that sector is to take it to a place of safety. No driver has the right to refuse to allow his car to be taken off the track, he must do everything he can to help and obey the marshals’ instructions. Once the car is in a place of safety the driver may, if the specific regulations of the event permit, work on it in order to re-start. In such cases other means, such as breakdown vehicles, cranes, etc. should not be brought into action until the driver has made it clear that he will not continue.
It is desirable that the driver stays near his vehicle until the end of the race or at least informs the post chief how his car may be lifted, or towed back to the pits.

No interpretations... more clear is water "In such cases other means, such as breakdown vehicles, cranes, etc. should not be brought into action until the driver has made it clear that he will not continue."

It need FIA investigation like second place in Monaco???
