In high cleanliness production environments such as semiconductor manufacturing, pharmaceuticals, precision electronics, aerospace and food processing, material handling equipment must deliver reliable lifting performance while complying with strict cleanroom requirements. KUNFENG cleanroom cranes feature fully sealed, dust-proof structure to minimize particle emissions and oil contamination, making them indispensable material handling solutions for cleanroom workshops.
What is Clean Room Crane
The clean room crane is a lifting device specially designed for clean environments. Its structure, materials, lubrication system, and motion control are all specially optimized to meet ISO 14644 cleanroom standards and industry regulations such as GMP.
Compared with conventional industrial cranes, cleanroom cranes offer the following characteristics:
Low particle emission design
Dust-tight sealed construction
Structural materials including stainless steel, aluminum alloy or special anti-corrosion coatings
Oil-free or low-volatility lubrication systems
Smooth and precise motion control
Easy cleaning and maintenance
Low-noise operation
Typical Application Environments
ISO Class 5 - 8 cleanrooms
GMP pharmaceutical workshops
Biological laboratories
Semiconductor wafer fabrication plants
Precision optics manufacturing facilities
Food processing plants
Main Types of Cleanroom Cranes
Overhead Cleanroom Crane
An overhead cleanroom crane is installed on runway beams at the top of the workshop and consists of main girder, end carriages, traveling mechanisms and cleanroom hoist. It covers the entire working area of the workshop and is suitable for large equipment installation, production line material transfer and heavy workpiece lifting. To maintain cleanliness, key components are fully enclosed, lifting mechanisms are fitted with dust-proof covers, and cable systems use clean cable chains or closed power supply systems.
In wafer fabrication, LCD panel production, high precision electronics assembly and similar industries, overhead cranes enable highly efficient, accurate, and reliable material handling.
Cleanroom Suspension Crane
Suspension cranes are mounted directly to the ceiling structure without supporting columns, maximizing usable space in cleanrooms. This design is ideal for space-restricted or low-headroom production environments. With the runway suspended overhead, the area below remains unobstructed for optimized production line layout. The crane runs smoothly with a compact structure, effectively reducing air turbulence and particle dispersion.
It is widely used in pharmaceutical workshops, biological laboratories, and electronics assembly lines for loads from 150 kg to 2000 kg.
Moveable Cleanroom Gantry Crane
A portable gantry crane is a freestanding lifting solution that does not require integration with the building structure. It consists of a gantry frame, horizontal beam, casters and lifting mechanism. Depending on the application, the crane can be manufactured from aluminum alloy, stainless steel, or specially coated carbon steel with cleanroom-compatible finishes. Its main advantages include high mobility, adjustable height, simple installation and no need for fixed runways.
It can be quickly deployed for equipment maintenance areas, food workshops, laboratories, temporary production lines and other applications, with flexible positioning as needed.
Workstation Cleanroom Jib Crane
Cleanroom jib cranes are mainly used for lifting and transferring materials within fixed workstations. Depending on installation, they are available as floor mounted jib cranes or wall mounted jib cranes. They provide 0° - 360° horizontal rotation coverage and are suitable for electronics assembly lines, sterile vessel handling in pharmaceutical workshops, food packaging and assembly stations. By improving lifting efficiency at individual workstations, jib cranes help reduce manual handling and minimize contamination risks.
Cleanroom Lifting Hoist Systems
The core lifting component of a cleanroom crane is the cleanroom hoist, designed to meet ISO Class 5 - 8 cleanliness requirements.
Common Types
High strength composite fiber belt hoist
Cleanroom synthetic rope hoist
Cleanroom chain hoists
Design Features
Fully enclosed structure
Low particle emission
No oil contamination
Precise variable frequency control
Anti-static design
Low vibration and high flexibility
How to Select the Right Cleanroom Crane
Define required cleanliness class
Determine rated load (100 kg – 20,000 kg)
Confirm working coverage (runway length, span, lifting height)
Select equipment materials based on working conditions
Consider environmental requirements (corrosion resistance, anti-static, easy cleaning)
Choose the appropriate level of automation
Ensure compliance with relevant international certification standards
