What are the defects of the bridge?

first, perhaps the defects: all parts of the bridge appear short-circuit appearance, such defects may constitute the operation of the current relay on the distribution cabinet, and the damage to the bridge is very serious.
Defects that will occur: there is a short circuit inside the bridge, this kind of defect is generally caused by the low quality of the cable, and there is no trace on the outside; maybe the whole cable will be burned or somewhere will be burnt, so that the cable is severely damaged at the defect; fourth, the defect that may appear is that the bridge needs only a short circuit, and the cable at the defect is slightly damaged, but there will still be obvious marks.

Such defects may occur because the current is too large or the cable quality is too poor.
Bridge maintenance items 1, bridge equipment balance cylinder operation and oil lubrication system oil circuit, cable tray vendors connection number inspection.
The conflict between the bridge equipment slider and the guide rail is relatively repeated, so necessary adjustments should be made to check the lubrication quality and piping of the joint to ensure excellent operation.

Punctual lubrication for the gear parts of bridge equipment: the gear box and internal parts are more likely to be damaged and loose because of frequent operation.

When there is noise in these parts, it can be lubricated first, and then according to the vibration, check the oil output and pressure of the oil injection points between the systems, and make appropriate adjustments.
