[0002] The 46t reach stacker is a special model for ports. Its telescopic arm is an important part of the lifting system. To ensure that the telescopic arm can be stably extended and retracted in the arm body during operation, it is required to control the crotch deviation and overall flatness of the left and right vertical plates on the inner wall of the arm body during the production process.
