| Top Running Double Girder Clean Room Overhead Crane

Cleanroom overhead crane is an intelligent material handling system designed for high cleanliness and high precision manufacturing environments. It combines double girder bridge structure with cleanroom electric lifting hoist to achieve vertical lifting, horizontal movement and precise positioning of materials in controlled environments and cleanroom workshops. It is widely used for heavy material handling applications in industries such as semiconductor manufacturing, pharmaceuticals, precision electronics, aerospace and food processing.

Main Structure and Working Principle of Double Girder Cleanroom Overhead Crane

Main Girder Structure: Designed with high-strength steel, featuring strong load-bearing capacity and excellent anti-deformation performance.

Clean Electric Hoist / Trolley: Equipped with dust-free designed chain hoist or synthetic belt hoist to achieve smooth lifting.

Top Running Rail System: Installed above the workshop to free up floor space and improve operation efficiency.

Sealed Drive System: Reduces lubricant leakage and particle diffusion.

Intelligent Electric Control System: Supports variable frequency speed regulation, precise positioning and remote control.

The cleanroom double girder crane operates via the bridge girder moving longitudinally along the workshop rails, while the trolley travels transversely on the double girders. Cooperating with the electric hoist to lift and lower heavy loads, it realizes efficient material handling in three-dimensional space.

Product Advantages of Cleanroom Overhead Crane

• Compared with single girder cranes, the double girder structure provides higher load-bearing capacity and improved structural stability, meeting the requirements for handling heavy workpieces and precision equipment.

• The lifting system adopts a sealed design to minimize the risk of lubricant leakage, metal wear particles and dust entering the cleanroom environment.

• Equipped with precision drive control and low-speed smooth operation modes, the crane effectively reduces load swing, positioning errors and the risk of workpiece collision.

• The optimized transmission system, low-noise motors and precision traveling components help reduce operating noise and mechanical vibration, ensuring stable performance in sensitive cleanroom environments.

• Customized designs are available according to different production environments and process requirements, allowing the crane to adapt to cleanrooms of various sizes, layouts and application conditions.

Frequently Asked Questions About Cleanroom Cranes

Q: Can you customize the crane according to cleanroom dimensions?

A: Yes, non-standard customization is available, including span, lifting height, lifting capacity and control system.

Q: How to ensure the cleanroom crane does not generate contamination during operation?

A: Pollution sources are effectively controlled by using low-dust-generating materials, fully sealed structures and oil-free or low-oil lubrication systems.

Q: Is automation integration supported?

A: Yes, it can be connected with MES systems or automated production lines to realize intelligent material handling.

Q: How to choose the right cleanroom overhead crane?

A: Clarify the maximum lifting capacity, workpiece dimensions and handling frequency; determine the required cleanroom class; select single-girder or double-girder structure based on load; choose cleanroom electric chain hoist or belt hoist; opt for wireless remote control or PLC intelligent control.

Q: What are the installation space requirements for overhead cleanroom cranes?

A: The effective height of the workshop, required lifting height, traveling rail position, power supply conditions, etc., shall be clearly defined.
