BNR/BNRT explosion-proof electric hoist is a lightweight and compact lifting device specially designed for industrial environments where explosive mixtures may exist. Featuring a compact structure, low self-weight, and strong lifting capacity, it is developed and manufactured in strict accordance with the latest explosion-proof standards.
The hoist adopts an explosion-proof structural design, with key exposed components made of special non-sparking materials to effectively prevent ignition risks caused by sparks or high temperatures. Its reliable explosion-proof performance has been verified through authoritative testing and certification, ensuring safe operation in hazardous environments.
Explosion-proof electric hoists are widely used in Class I explosion-proof coal mine non-mining areas and Class II hazardous environments containing IIA, IIB, or IIC flammable gases, vapors, and air mixtures. The temperature group covers T1-T4 levels. The standard working temperature range is -25℃ to 40℃, and the equipment is mainly designed for indoor applications. Additional protective measures are required for outdoor operation.
Explosion-proof electric hoists are designed for lifting operations in hazardous environments where explosive gases, vapors, or dust may exist. Typical applications include:
Coal Mining Industry:
Used in non-mining working areas of Class I explosion-proof coal mine environments for material lifting and handling.
Chemical Industry:
Suitable for Class II hazardous locations containing IIA, IIB, and IIC flammable gases or vapor-air mixtures.
Oil and Gas Industry:
Applied in areas involving flammable gases, petroleum products, and combustible liquids, covering T1-T4 temperature classifications.
Dust Hazard Environments:
Used in industries with combustible dust risks, such as grain processing, wood processing, and similar production facilities.
Explosion-Proof Structure:
The specially designed explosion-proof housing effectively contains internal explosions and prevents sparks or flames from escaping, improving operational safety.
Spark-Resistant Components:
Key components such as motors, electrical wiring, and switches are manufactured with spark-resistant materials to reduce the risk of ignition in hazardous environments.
Reliable Sealing Design:
The sealed structure prevents the entry of flammable gases, vapors, and dust, reducing the possibility of ignition caused by external factors.
Corrosion Resistance:
Special coatings and durable materials improve resistance to chemical corrosion, allowing stable operation in harsh industrial environments.
Efficient Heat Dissipation:
Optimized cooling design helps control operating temperature and improves equipment reliability during continuous operation.
Wide Application Range:
Suitable for different explosion-proof classifications and widely applied in chemical plants, coal mines, oil and gas facilities, and other high-risk industries.
Lightweight and Durable:
Compact structure, high-strength components, and reliable manufacturing technology provide long service life with convenient installation and maintenance.
