It's nobody's fault. I've heard that the boom of Liugong excavator is prone to cracks, and forklift trucks have never heard of it, but I know that everything is full of energy, either on purpose or with poor quality. In short, you must drive a forklift slowly. This year, forklifts killed people, and forklifts hit excavators. Always like this. Whether it's your own car or your boss's car, you should take good care of it. The arm shaft of the forklift will wear. At that time, when you shoveled something, it broke with one inch of strength. It's simple. There should be no welding marks on the girder. The welding temperature is not compatible with the original iron of the finished forklift, and so on.
