在我厂的生产车间、仓库中共使用有A571型电动单梁起重机20多台,其中有一半使用期已超过十年。虽然每年都进行检修,但使用中仍然出现爬轨故障(即车轮轮缘爬上轨道踏面),导致生产被迫中止。如果找不到产生这种现象的原因,并予以排除,只单纯地把起重视车轮撬入轨道,少则一两天,多则一星期, In our factory’s production workshop, the warehouse uses a total of more than 20 electric single-girder cranes A571, of which half have been used for more than ten years.
