The special crane system for clean room is mainly used in electronics, pharmaceutical, bioengineering, medical, laboratory, peninsula, lithium battery, aerospace, LCD panel and other industries. The core technology application of clean 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. We can customize clean driving according to customer needs.
