落さないように慎重に取扱わなければならなかった。However, since the movable support part has a large weight, it requires great effort to remove the movable support part each time the crosshead assembly is replaced, and when the movable support part is removed, the cartridges therein are removed. Another worker has to hold the crosshead assembly to prevent it from falling, requiring a large number of workers to replace it, and also preventing the movable support part and the crosshead assembly from falling. It had to be handled with care.
