处理桥式起重机挠度及啃轨的新方法

New Method Processing the Deflection and Rail Gnawing of Bridge Crane

桥式起重机在长期使用中,主梁会产生下挠,还会出现啃轨现象。通过分析和理论计算,拉钢丝绳法和圆弧轮轨法对处理桥式起重机挠度和啃轨具有很好的效果和实用价值。

The main girder deflects and the rail is gnawed after a bridge crane has run for a long time. According to the analysis and theoretical calculation, drawing wire rope method and wheel track circular method have the better practical effect for processing the deflection and rail gnawing, of bridge crane.
