Steel pole after a certain period of use, wear and tear inevitably occur naturally, the phenomenon of deformation and damage to components. Therefore, we must promptly carry out maintenance work on the poles to ensure product quality, extend the life of steel is essential.

Electrical steel steel repairs are generally divided into small repair in January, on a quarterly basis a repair, overhaul a year.

Minor repairs: regular part of the damage, loss of parts, bent or cracked ribs, mold is bad, there is a gap, running syrup or slightly deformed wall bending phenomenon corrective maintenance.

In repair: use of a longer period, the extent of damage to the heavier, larger deformation of the mold, the repair should be carried out, especially mold tube weld, running wheel.

Overhaul: Where to run excessive wheel wear, less than the standard size of 10mm or more, you need to replace. Both ends of the connection flange and flange severely deformed, die badly damaged, the entire root steel severely bent, distorted, badly damaged parting, after correction is still uneven, the wall plate wear rate of more than 30% of its thickness, etc. cases, required by custom and special planer lathe. In order to ensure the overhaul quality, reduce production costs and maintenance costs, specially designed and manufactured for lathes, proved, both to improve the quality of steel overhaul, but also reducing maintenance time and play a good effect.
