| Abstract: | On the basis of studying the probability distributing and the interference model of the pressures on driving wheels and the permissible pressures for portal crane, the author presents the probability solution of non-skidding event, advances a novel method on checking computation of reliability for skidding of portal crane. The method is the modification for the method of checking skid by least pressure on driving wheels, which is too strict to satisfy. The method raised by this paper is more suitable for practice use of portal crane. |
