The steel crane beam

One part of the steel crane beam system design. The steel crane beam is for bridge crane steel components. Crane beam type load on the crane beam and action are: crane vertical load, horizontal and vertical horizontal load, crane repair platform of live load, the part weight of crane beam system, supporting the roof structure of the crane beam system load and wall frame structure. Based on the hoist gantry crane of the steel crane beam damage reason in service, this paper discusses the current steel crane beam design and the difference of the actual stress and its harm, put forward the problems existing in the current in the design of the steel crane beam, and studied and analyzed the existing problems and the breakage of the beam in the design of beam and results in the decrease of its reliability.
