Stainless steel cleanroom crane refers to a professional special model that prevents dust from occurring when heavy objects are transported by a crane inside and outside the clean room, and can utilize the limited space inside and outside the room to ensure the maximum use space. In order to prevent dust from occurring, stainless steel plates are laid on the running surface of the wheels. At the same time, the materials of the wheels and guide wheels are made of engineering plastics. For the lifting chain, a sheath device that prevents the scattering of tiny flakes is adopted to ensure cleanliness in the clean room.
