桥式起重机行走轮啃轨、爬轨及跳轨在运行中是常见的故障,分析原因有以下几点: 1.行走轮不在一个水平线上;2.行走轮的相距不等、不平行;3.桁架变形;4.各传动联轴器松弛或损坏;5.行走轮轴承松弛或损坏。在修理中,4、5两项故障易于检修;1、2、3项故障在差距较小的情况下,检修就相当困难了。我厂有两台桥式起重机啃轨,跑轨频繁,曾经多次检修,故障依然存在。我厂工程枝术人员 Bridge crane walking wheel gnawing rails, climbing rails and jump track is a common fault in operation, the analysis of the following reasons: 1. Walking wheel is not a horizontal line; 2 walking wheel distance range, not parallel; 3 Truss deformation; 4 each drive coupling loose or damaged; 5 walking wheel bearings loose or damaged. In the repair, 4,5 two faults easy to repair; 1, 2, 3 fault in the case of small gap, overhaul is quite difficult. I plant two bridge crane gnawing rails, running rails frequently, repeatedly maintenance, the fault still exists. I plant branch engineering staff
