| Design Features of Cleanroom Belt Hoist Crane

In semiconductor manufacturing, pharmaceutical production, and high precision electronic assembly environments where cleanliness control is extremely strict, overhead lifting equipment must handle material handling tasks while ensuring that no source of contamination is released during operation. Traditional chain hoists, due to friction wear, lubricant leakage and particle shedding, are difficult to meet high-level cleanroom standards. The KUNFENG belt hoist crane adopts low particulate structure and oil free belt transmission design, minimizing contamination while maintaining reliable lifting performance, making it an essential material handling solution for modern cleanroom workshops.

Low-Dust Emission Structure for Contamination Control

The belt hoist replaces traditional metal chains with high strength composite fiber lifting belts, reducing metal-to-metal contact surfaces and minimizing wear induced dust generation. Through a fully enclosed structure, optimized motion contact design, and the use of non-particle-releasing materials, particle generation during operation is significantly reduced. The belt-driven system ensures smoother movement with less shock and vibration, making it suitable for ISO Class 5 - 8 cleanroom environments.

Oil-Free and Clean Lubrication System Design

Our cleanroom belt hoist adopts an oil-free lubrication concept or micro-sealed lubrication system. Solid lubrication materials or long-life sealed bearing structures are used to fully isolate lubricants inside components, preventing any contact with the external clean environment and eliminating the risk of oil mist contamination at the source.

Low Noise and Low Vibration Operation System

The belt hoist crane achieves low-interference operation through the following technologies:

• High precision gear machining technology

• Optimized motor drive control system

• Rubber or polymer damping and buffering structure

• Low-friction transmission design

This ensures low operating noise, smooth start/stop performance, and no impact load during operation.

High Precision Positioning and Smooth Control System

In semiconductor and precision electronics industries, even minor positional deviations can affect product quality. The belt hoist is equipped with:

• Variable Frequency Drive (VFD) control system

• Precise lifting positioning control

• Anti-sway control technology

• Micro-speed operation mode

These functions ensure high stability during lifting, positioning and assembly processes.
