Product Advantages
Certified Explosion-Proof Safety
Engineered and certified for use in hazardous locations, this hoist features specially designed explosion-proof motors (Exd II BT4 / CT4) and electrical components. All potential ignition sources are securely contained, providing you with the highest level of safety and peace of mind when operating in volatile atmospheres.
Robust and Durable Construction
Built for demanding industrial use, the Weiyuan HB/BHC hoist is constructed from high-strength steel and features a powerful, reliable gear train. The hardened components and high-quality wire rope ensure a long service life and consistent performance even under rigorous operating conditions.
Compact Design, Powerful Performance
Despite its heavy-duty safety features, the hoist maintains a compact and logical structure. This design allows for easy installation on single-girder cranes, monorails, or fixed suspension points, providing powerful lifting capabilities without occupying excessive space.
Precise and Stable Operation
The hoist is equipped with a high-performance conical rotor brake motor that provides strong, reliable braking the moment power is disengaged. This, combined with optional dual-speed functionality, allows for precise and stable load positioning, which is critical for handling sensitive materials.
Versatile Customization
Weiyuan understands that every hazardous environment has unique requirements. We offer extensive customization options, including different lifting capacities, heights, speeds, and explosion-proof ratings to create a hoist that perfectly matches your specific application and safety protocols.
Application Scenarios
Chemical and Petrochemical Plants
Essential for maintenance, material handling, and production processes in facilities where flammable chemicals and gases are present. It safely lifts pumps, valves, and containers in high-risk zones.
Oil and Gas Industry
Ideal for onshore and offshore platforms, refineries, and storage facilities. The explosion-proof design is critical for lifting equipment and supplies safely in environments where hydrocarbons are present.
Mining Operations
Provides a safe and reliable lifting solution for underground and surface mining operations where coal dust or methane gas creates a potentially explosive atmosphere.
Paint and Coatings Manufacturing
Perfectly suited for workshops and production areas where flammable solvents and vapors are part of the manufacturing process, ensuring safe handling of raw materials and finished products.

FAQ
Q: What is the difference between BT4 and CT4 explosion-proof grades?
A: Both are grades for gas-explosive environments. CT4 indicates a higher level of protection, suitable for a wider range of flammable gases with lower ignition temperatures, such as hydrogen or acetylene. The choice depends on the specific substances present in your work area. We can help you select the correct grade.
Q: Can this hoist be used outdoors?
A: Yes, with appropriate modifications. For outdoor use, the hoist can be fitted with protective rain covers for the motor and electrical box to ensure it is protected from the elements while maintaining its explosion-proof integrity.
Q: What information do I need to provide to get a quotation for an explosion-proof hoist?
A: For an accurate quotation, please provide: 1) The required lifting capacity, 2) The required lifting height, 3) The specific explosion-proof grade needed (e.g., Exd II BT4) or the types of flammable materials in the environment, 4) Your power supply details (Voltage, Hz, Phase), and 5) The intended application.
Q: Does the explosion-proof hoist require special maintenance?
A: It requires standard hoist maintenance procedures, but with special attention to the integrity of the explosion-proof enclosures. Regular inspections should ensure that all seals, gaskets, and flameproof joints are intact and undamaged to maintain their safety certification.
Q: How does Weiyuan ensure the quality of its explosion-proof hoists?
A: With nearly 40 years of manufacturing expertise, Weiyuan builds every explosion-proof hoist under a strict, ISO-certified quality management system. We use certified explosion-proof components, conduct rigorous inspections, and perform comprehensive load and safety tests to ensure each hoist complies with the highest international standards for safety and reliability in hazardous environments.
