Is the tower crane allowed to install advertisements?

advertising slogans cannot be hung on tower cranes. "No matter where billboards are set up, they must be approved." Generally speaking, it is not allowed, especially for large-scale monolithic billboards, otherwise it will not pass the acceptance of the safety supervision station.

the reason is that the billboard installed on the forearm will affect the maximum lifting limit, and the billboard installed on the rear arm will have great wind resistance in strong wind, which may cause the tower crane arm to rotate with the wind. Even when someone controls the work, it may cause the operator to operate abnormally because he does not adapt to the push caused by wind resistance, which is extremely unsafe.
