Actually, the part of the bridge that is lifted should stop when the weight reaches a certain limit value, as a safety stop. But a programming in the motors that lift the bridge was incorrect.
— The limit value was far too low. Therefore, the bridge stopped at a load that was much lower than what it can actually handle, says Axel Wannerskog of the City of Gothenburg to SR and adds:
— It is the human factor. Something has happened in the code knocking.
Since April, the error has been fixed.
