For clean production areas where the crane must address both explosion risk and contamination / particle-control requirements.

Henan Mine Crane zjjb clean explosion-proof crane showing the crane structure and lifting arrangement.
The ZJJB clean explosion-proof overhead crane combines explosion-protection technology with clean-environment requirements. The source identifies semiconductor manufacturing and precision chemical workshops as primary applications where both explosion risk and dust control are important.
This type should never be quoted from crane capacity alone. Buyers need to provide both the hazardous-area specification and the cleanliness / contamination-control requirement, because coatings, sealing, wear materials, dust collection and exposed components all affect the final configuration.

Special crane combining explosion-protection technology with clean-environment requirements.
Source identifies semiconductor manufacturing and precision chemical workshops as primary applications.
Variable-frequency control is used for stable operation and efficient handling.
For a new purchase, any capacity, span, speed, duty, clean-class or explosion-protection value that is not published on the source page should be confirmed from the actual project rather than copied from a similar crane model.
The product is designed for applications where both contamination control and explosion protection are required.
The source confirms anti-static and spark-suppression treatment of mechanical parts.
Enclosed and sealed construction reduces dust accumulation in the crane body and drive interfaces.
Non-corrosive wear materials and collection devices are part of the source design concept.
The source specifies stainless-steel hooks, wheels and other direct-contact parts with passivation treatment.

Source-confirmed product facts:
Buyer-defined items for quotation:
| Semiconductor Manufacturing | Clean hazardous-area lifting around high-value process equipment. |
| Precision Chemical Workshops | Material and maintenance handling where explosion protection and contamination control overlap. |
| High-Purity Process Areas | Special lifting where dust adhesion and generation must be controlled. |
| Clean Classified Rooms | Applications requiring both an approved clean specification and hazardous-area protection. |
Provide the cleanroom or process cleanliness class, particle-control requirements and any approved material / coating restrictions.
Provide the approved explosion-protection classification, medium, group and temperature information.
State whether oil, corrosion products, wear particles or other contaminants have special limits.
Provide the normal crane sizing data and equipment / room layout.
Explain required cleaning methods, access restrictions and whether components must tolerate specific cleaning agents.
Before manufacture and installation, confirm runway span, rail or runway-beam condition, elevation, straightness, available headroom, electrical supply and erection access. The hazardous-area boundary and equipment classification should also be confirmed before final electrical selection.
Maintenance should follow the final supplied crane manual and the plant's hazardous-area procedures. Routine inspection should cover hoisting mechanisms, brakes, ropes, hooks or attachments, wheels, drives, fasteners, limits, seals and explosion-protected electrical components. Clean explosion-proof cranes also require cleaning and inspection procedures that preserve contamination-control performance.

It is a special crane designed to satisfy both hazardous-area explosion protection and clean-environment contamination-control requirements.
Semiconductor manufacturing and precision chemical workshops are specifically listed.
The source page does not publish one universal cleanroom class. The required class must be provided by the buyer and incorporated into the project specification.
The source describes anti-static coating, sealed construction, non-corrosive wear materials, collection devices and stainless/passivated contact components.
Yes. Variable-frequency control is explicitly stated by the source.
Send your hazardous-area classification together with lifting capacity, span, lifting height, runway length, workshop drawing, operating cycle and control requirements. Henan Mine Crane engineers will review both the lifting duty and the explosion-protection requirements before preparing a project-specific configuration and quotation.
