Causes of trolley of bridge crane running on both sides of track

1, if the newly installed bridge crane has this phenomenon, it means that there is something wrong with the gauge, or the crane axle is not on the axis, just like a person's eight-character step. Please check the pressure gauge.

2. If this problem occurs after a period of time: 1) It is possible that the gauge has moved, so check it; 2) It is also possible that there is something wrong with the axle of the bridge crane, which leads to the change of the crane gauge. Please check it.
