Wear resistant 8ton excavator main standard boom

  Brother, is the main boom of the 8-ton machine broken again? GuoRun's this 9-ton one saves you from having to constantly go to the welding machine.   Well, to be honest, for people in our line of work, who hasn't been messed with by a broken boom? The 8-ton small excavator was originally quite flexible. But when it comes to using the breaker or pounding hard rocks, the original boom can't handle it. Weld seams crack, the boom bends, you go to the repair shop every other day. You weld it and it cracks again, then you weld it again. The work is all delayed, you don't get the money, and you just keep getting messed around. You think about it, right?    I was also bothered by this at that time. Later, I replaced it with the GuoRun 9T standard main arm, and that finally made things more manageable. How did they do it? Actually, it was quite simple - they just made the material thicker, increased the amount of manganese steel, controlled the welding temperature properly to prevent stress…
