The clean room crane specially used in the aerospace workshop is a clean room crane equipment specially used in the clean room space. The clean room crane has the function of dustproof and anti-pollution, and will not generate dust and cause pollution to the clean room during operation. The core technology application of clean room crane is mainly manifested in two aspects. In terms of new materials, the dust-proof guide rail lifting parts of clean room cranes have high requirements on materials, and SUS wear-resistant and corrosion-resistant materials are mainly used; MCNylon wear-resistant materials are used for wheels and gears. The application of new materials can greatly reduce lifting or large and small vehicles. Metal dust particles generated by friction during operation.
