Advantages of the ZJJB Clean Explosion-Proof Crane Manufactured by Henan Mine
The crane employs computerized automatic control from a central control room, enabling it to automatically navigate pre-set work routes between locations such as the reduction furnace platform, cleaning platform, transfer platform, and silicon rod removal tools.
The travel mechanisms for both the main and trolley cars employ laser barcode positioning. The trolley's laser barcode reader is mounted on the trolley itself, while the barcode strip is installed on the web of the main car's main beam. The main car's positioning laser reader is mounted on the end beam, with the barcode strip installed on the U-shaped trough that collects powder residue.
The crane features lightweight, maintenance-free design with extensive use of anti-static, wear-resistant, and corrosion-resistant materials. Wheels are constructed from stainless steel, with stainless steel channels installed on both sides of the track. The reducer employs a fully enclosed, high-seal design ensuring zero oil leakage contamination. It utilizes a high-protection-rated, fanless explosion-proof m.otor, and the double-sealed brake effectively prevents the leakage of contamination particles generated by transmission wear within the motor
The main crane wheel sets feature fully enclosed designs with stainless steel wheels. Other components undergo high-grade rustproof surface treatment to prevent metal corrosion contamination, while self-lubricating, fully sealed bearings eliminate lubrication pollution.

Features of the ZJJB Clean Explosion-Proof Crane Manufactured by Henan Mine
Automatic Operation Mode:
When on-site personnel require lifting operations, they manually hook the lifting device using an explosion-proof remote controller. After completion, they select the corresponding function via the explosion-proof remote controller. Upon confirmation of operational key points by on-site operators using explosion-proof remote controllers, the crane automatically travels to the exact position directly above the target location along a pre-set path. It then lifts the restoration furnace or unloading tool. After completing the action, an audible and visual alarm signals the start of operation. After the operator confirms critical movement points via the explosion-proof remote, the crane automatically navigates its pre-programmed path to position directly above the target location. It then lifts the regenerator or unloads the rod tool. Upon completion, an alarm signals the task's finish.
During operation, pausing can be initiated if issues arise. Once resolved, pressing the “Continue” button resumes the process. In case of an emergency fault, press the emergency stop button on the remote control to halt the equipment immediately and prevent further issues.
Manual Operation Mode
Rotate the selector switch on the explosion-proof control cabinet to the “Manual” control mode. On-site personnel can then operate the crane manually using explosion-proof buttons, controlling each mechanism individually. Remote control and handle control are mutually exclusive; only one control method can be active at a time.

Can your cleanroom explosion-proof cranes meet the ISO Class 7 cleanliness requirements of our workshop? Will they generate dust that could contaminate products?Professional Answer: Absolutely! Our clean explosion-proof cranes are designed to ISO 5-8 cleanliness standards. For ISO 7 workshops, we implement targeted optimizations: First, all air-contacting components use 304 stainless steel with electropolished surfaces, eliminating any uneven surfaces or dead corners where dust or bacteria could accumulate. Second, the entire unit features a fully sealed structure. Lubricants in the motor and reducer will not leak, and dust covers are installed on the operating mechanisms to prevent dust generation. Third, wheels utilize silent self-lubricating bearings, ensuring low operational noise (≤65dB) and preventing metal dust generation from friction.
-
What is the explosion-proof rating of your cranes? Can they adapt to our workshop's combustible dust environment?Professional Answer: Our cleanroom explosion-proof cranes can be customized to your environment's explosion-proof rating. Common options include ExdⅡBT4 (suitable for most combustible gas/vapor environments) and ExdⅡCT4 (suitable for high-risk environments like hydrogen or acetylene). For combustible dust environments, we also offer custom dust explosion-proof models (DIPA21 T135℃), fully meeting your requirements.
