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.
