KUNFENG belt hoist adopts cleanroom grade belt lifting technology, featuring oil-free operation and low vibration performance, ideal for material handling in ISO Class 4 - 8 cleanroom environments.
The belt hoist system is a material lifting solution specifically designed for cleanroom workshops. It uses high strength fiber belts instead of traditional wire ropes or chains as the lifting medium, featuring low particle emission, oil-free operation, low vibration and high precision. Equipped with dust-proof sealing system and precise variable frequency control technology, it is suitable for precision lifting operations in ISO Class 5 - 8 cleanrooms.

In 2026, KUNFENG successfully delivered customized cleanroom belt hoist solution to a semiconductor manufacturing company in Poland, used for handling precision equipment and hoisting components in wafer fabrication workshops. From design and production testing to on-site installation and commissioning, the entire project was implemented in strict accordance with cleanroom equipment standards, helping the customer improve lifting efficiency and production stability in clean environments.
Project Background and Client Requirements
The Polish customer specializes in wafer packaging and precision electronic component manufacturing. During the equipment selection process for their newly built cleanroom facility, they required the lifting system to meet the following conditions:
Compliance with ISO Class 5 cleanroom standards
Oil-free lifting operation without contamination
Smooth operation with low vibration
Precise positioning to prevent damage to delicate components
Capability for continuous high frequency operation

KUNFENG Customized Design Solution
High strength polyester lifting belts were used instead of traditional chains and wire ropes to minimize metal friction particles and oil contamination risks at the source.
The motor and gearbox adopted sealed structure, while critical internal components received dust-proof treatment to prevent particle release into the air.
By optimizing the motor control system and lifting mechanism, the hoist achieved smoother starting, braking and micro-speed positioning, reducing load swing and improving the safety of precision lifting operations.
The hoist body featured corrosion-resistant coating materials, while the hook was made of 304 stainless steel and equipped with anti-static components to prevent dust attraction caused by static electricity during semiconductor production.
According to the customer' s workshop layout, the lifting height, span, control method and installation configuration were customized to ensure compatibility with existing workstations.
