Henan Mine explosion-proof electric hoists come with official explosion-proof certificates, suitable for chemical, oil & gas and dust explosion-proof workshops. We provide detailed explanations on explosion-proof grade selection, working condition matching and safety configurations, as well as one-stop solutions for explosion-proof electric hoists.
What is an explosion-proof electric hoist?
Explosion-proof electric hoist is a light and small lifting equipment developed specifically for explosive hazardous environments. The motor, electric control box and limit switch of the equipment are all equipped with flameproof enclosures. Non-sparking alloy materials are adopted for moving parts such as wheels and hooks, which can effectively prevent sparks from escaping. It is suitable for workplaces with flammable gases, volatile vapors and combustible dust. It is often used together with explosion-proof single-girder and double-girder overhead cranes to carry out lifting and transferring operations of materials.
Company Profile of Henan Mine
Henan Mine Crane Co., Ltd. was founded in 2002 and is located in Changyuan, Henan, known as the "Hometown of Cranes in China". It holds complete qualifications for manufacturing special equipment and production licenses for explosion-proof products. The company has a professional R&D team specializing in explosion-proof technology, capable of independently completing the design, production and complete supporting services of explosion-proof wire rope electric hoists and explosion-proof chain electric hoists. Its products come with official third-party explosion-proof inspection certificates and comply with China's GB3836 explosion-proof standards. Customization for international explosion-proof certifications including ATEX and IECEx is also available. The company’s products are supplied to more than 130 countries and regions worldwide. Adhering to the philosophy of "Quality builds the brand, integrity shapes the future", it keeps assisting factories in high-risk industries to achieve safe, compliant and efficient lifting operations.
Solutions to Core Challenges
Avoid risks of safety incidents and uphold the bottom line of safe production in the factory.
The biggest hidden hazard in hoisting operations within high-risk environments is the loss of control over ignition sources. In accordance with the plant's hazardous area classification (Zone 1/Zone 2 gas environments and Zone 21/Zone 22 dust environments), we deploy equipment with matching explosion-proof ratings. The complete machine motor, electrical control box and limit devices adopt flameproof sealing structures, while travelling wheels and lifting hooks are made of non-sparking alloy materials. These designs effectively contain internal electrical sparks and prevent ignition of surrounding combustible materials. We help enterprises reduce the risk of explosions and fires, and avoid production shutdowns and liability repercussions stemming from serious work safety incidents.
Ensure smooth passage through safety supervision and environmental impact assessment inspections and eliminate troubles in certification acquisition.
Some non-standard equipment available on the market has problems such as counterfeited certificates and inconsistent information between nameplates and explosion-proof certificates. After the equipment arrives at the site, it cannot pass safety supervision inspections, resulting in equipment idling and construction schedule delays.
Every explosion-proof electric hoist manufactured by Henan Mine comes with a valid explosion-proof certificate corresponding to the single unit. The certificate number is traceable and complete sets of documents are provided. Meanwhile, technical staff will organize acceptance documents to reduce the document preparation workload for enterprises' safety management departments and prevent situations where purchased equipment cannot be put into operation.
Reduce the full-lifecycle operation and maintenance costs of equipment and cut downtime losses
Explosion-proof equipment differs from ordinary lifting hoists. Maintenance carried out by non-professional teams can easily damage flameproof surfaces and result in loss of explosion-proof performance.
Relying on our nationwide service network, we provide standardized inspection solutions for explosion-proof equipment and guide enterprises in daily maintenance. We offer prompt on-site maintenance services in the event of malfunctions and supply genuine explosion-proof spare parts. This prevents equipment scrapping caused by improper maintenance, minimizes equipment downtime, and ensures continuous operation of production lines.

Mainstream Applicable Industry Scenarios
- Petroleum, chemical and refinery plant areas, raw material workshops and tank storage areas
- Pharmaceutical factories, paint spraying workshops and ink production plants
- Gas filling stations, hazardous chemicals storage and logistics parks
- Dust explosion-proof workshops for flour, grain processing, wood powder processing and other industries
- Workshop for Transfer of Coal, Coal Chemical and Metallurgical Hazardous Goods
- New Energy Lithium Battery and Electrolyte Production Workshop
For flammable and explosive plant areas, the procurement of explosion-proof lifting equipment should not merely focus on price comparison. Safety compliance and long-term stable operation are the core requirements.
Henan Mine is more than a manufacturer of explosion-proof electric hoists; it is a safety partner for lifting operations in high-risk industries. Starting from working condition requirements, we provide full-cycle support covering model selection planning, production and manufacturing, on-site installation and commissioning, as well as subsequent inspection and maintenance. We help enterprises consolidate the safety barrier for lifting work to achieve compliant production and stable operation.

FAQs
Q: We are unsure of the hazard classification of the plant area. Could you help us determine the appropriate model selection?
A: Sure. You only need to provide the types of media in the plant, workshop ventilation conditions and production processes. Our technical staff will help sort out working conditions and recommend solutions with corresponding grades such as Ex d IIB T4 and Ex d IIC T4 and dust explosion-proof to avoid incorrect model selection.
Q: For overseas export projects, can you provide international explosion-proof certifications?
A: Yes. Apart from domestic explosion-proof certificates, we can apply for ATEX and IECEx explosion-proof certifications as required by target countries to meet customs clearance requirements and local safety supervision standards for overseas factories and engineering projects.
Q: We have an existing ordinary single-girder overhead crane. Can it be put into use directly by only replacing the explosion-proof electric hoist?
A: Simply replacing only the hoist is not recommended. All electrical components of the complete lifting system need to comply with explosion-proof specifications. We can assess the feasibility of renovating the whole set of equipment and provide compliant renovation solutions to prevent explosion-proof loopholes.
