The dust-free clean electric hoist is specifically designed for lifting equipment in environments with strict cleanliness requirements, such as clean rooms, food and pharmaceutical industries, and precision electronics manufacturing. The core design focuses on dust and contamination prevention to ensure stable and reliable lifting performance.
It features a fully enclosed dustproof structure to ensure no particle contamination during the lifting process. The entire hoist is made of stainless steel or corrosion-resistant aluminum alloy materials, with a smooth surface that facilitates cleaning and disinfection, while also being resistant to corrosion from common chemical solvents used in workshops.
The hook is treated with mirror polishing to reduce dust accumulation. The steel wire rope is coated with stainless steel or polyester fiber coating to maintain cleanliness. Users can also choose high-strength polyester fiber slings as an alternative to metal cables, further reducing contamination risks. Key components such as limit switches are also sealed to prevent particles from affecting accuracy.
The control box is fully sealed, with buttons made of silicone or a touchscreen to avoid particle generation from mechanical wear. A wireless remote control is used to reduce surface contact contamination. The operating noise of the entire hoist is kept below 60 decibels, meeting the strict noise environment requirements of clean rooms.
The dust-free electric hoist is designed for high cleanliness environments, widely used in clean rooms, food processing, pharmaceutical manufacturing, and precision electronics industries. The core design focuses on dust and contamination prevention, ensuring efficient lifting operations while maintaining the cleanliness of the environment. This hoist is especially suitable for workplaces requiring extremely high cleanliness standards, ensuring that lifting operations do not cause contamination.
The hoist is equipped with a seamless 304 stainless steel shell, mirror-polished to completely eliminate dust generation. The motor and transmission system use multi-layer seals to ensure zero contamination during operation, meeting ISO Class 4 and higher cleanliness standards.
Innovative magnetic sealing technology eliminates the need for traditional gear lubricants. The use of self-lubricating bearings and ceramic-coated components thoroughly prevents oil leakage, making it suitable for high-demand environments such as food and pharmaceuticals.
It is equipped with a brushless servo motor, generating noise levels below 55 decibels. The intelligent variable frequency control reduces energy consumption by 40% compared to conventional models, offering energy savings and environmental friendliness.
The hoist supports both touchscreen and wireless remote control modes. It includes built-in operation data recording capabilities for real-time equipment monitoring, and enables remote fault diagnosis.
The modular quick-disassembly structure allows for deep cleaning within 30 minutes. All interfaces are dustproof, and maintenance requires no special tools, significantly reducing downtime.
