我段用的轮对,除从段修车分解下来能用的部份轮对外,全部用车轮厂轮对,平均月用量600左右。 轮轴组发现这些轮对轴颈上存有粗糙、刀纹、波纹、麻点等缺陷,这些缺陷目前越来越多,已约占90％左右。 我们认为这些有缺陷的轴颈,不仅是规章所不允许,而且在使用上也是非常有害的。这不仅会给车辆带来燃轴事故,而且其后果 I use the paragraph of the wheel, in addition to repair from the segment car can be used to break down part of the wheel, all with wheel factory wheel, the average monthly amount of 600 or so.
