54 Cleanroom and Explosion-Proof Cranes for Hongyuan’s Polysilicon Project
A 54-unit package combines cleanroom explosion-proof double-girder hoist cranes and dust-explosion-proof single-girder cranes.

The project and its handling task.
Henan Mine Crane manufactured 54 crane units for Hongyuan Energy’s 100,000-tonne high-purity crystalline-silicon project. The equipment includes cleanroom explosion-proof electric-hoist double-girder cranes and dust-explosion-proof single-girder cranes.
The project combines contamination control with hazardous-area operation. Intrinsically safe and flameproof components, variable-frequency drives, corrosion-resistant antistatic coating and dedicated permanent-magnetic dust-recovery devices form part of the supplied approach.
Control particles and ignition risks in high-purity silicon production.
Polysilicon production can demand both a clean environment and protection for classified gas or dust zones, with lifting equipment operating near sensitive process tools.
Confirm cleanliness target and the formal gas or dust classification.
Select hoist and attachment arrangements for equipment maintenance and material transfer.
Test cleaning, electrical protection and operating interlocks at the site.

Equipment programme manufactured.
The equipment programme addresses the project’s combined cleanroom and hazardous-area conditions. Its configuration separates contamination control, motion and explosion protection into coordinated crane requirements.
For a similar project, separate the cleanliness and hazardous-area requirements, then combine them in the crane specification. Select sealed or low-particle components, explosion-protected drives and controls, and safe handling routes for each process room.

Questions before specifying a similar crane.
Can the same project crane be supplied for my site?
We customize the capacity, span, lifting height, attachment and controls to the load, building or yard layout and operating cycle. Cleanroom class and cleaning regime is one of the inputs to review before final equipment selection.
How are certification, quantity and lead time agreed?
Single-crane and fleet enquiries are welcome. Define the destination and required standards in the enquiry. The project offer confirms certification and inspection documents, the quantity, drawing approval and manufacturing schedule, with the shipping and site-service boundaries.
What should acceptance and after-sales support include?
Agree the inspection plan, representative load and functional tests, operator training, maintenance instructions, spare-parts scope and fault-recovery procedures. For this application, include certification and acceptance requirements in the technical review.
