In the gap at the lever hoist a grinding wheel to grind the weld groove

In the gap at the repair with a grinding wheel to grind the weld groove . When filling welding, arc welding best DC reverse polarity . Arc should be as short as possible , electrode diameter 4mm, current is about 210-240a. Welding rod should tend to the direction of motion 20 ° -30 °. Fill welding work from the beginning until the other end of the drill hole cracks , and also on the opposite side welding , the 1.5 ton electric chain hoists weld should not exceed the height of the base plane 1-2mm. When welding environment temperature should be above 0 ℃. As used herein, the Suzhou Industrial Equipment Sen Muda more information, please introduce you to how do electric stacker hydraulic system maintenance in themini electric hoist of electric forklift trucks passing plays pressure , lubrication , cooling and sealing effect, the inappropriate choice of hydraulic oil hydraulic system failure and durability of the early decline. When grade hydraulic oil should randomly select "Manual" specified in special circumstances need to use on behalf of the oil, it should seek the same performance as the original grade performance
