Abstract: Some steel mill continually molten steel accepts cross, the originaldesign is 75t and the 32t two driving, as a result of the production craft request, must change the 75t driving the 110t driving. Therefore, carried on the reinforcement to the steel crane beam, theunion has been actual to two reinforcement designs method has carriedon the intensity and the rigidity examination.
Keywords: crane girder; intensity; rigidity
