About Weihua

Description：

Explosion-proof electric hoists are lifting equipment designed specifically for flammable and explosive environments. They utilize explosion-proof motors, electrical components, and mechanical structures, complying with explosion-proof standards such as ATEX, IECEx, and GB3836, effectively preventing explosions caused by electric sparks or high temperatures. Key features of explosion-proof hoists include high explosion-proof ratings (such as Ex dⅡB T4), multiple safety features (overload, limit switches, and anti-static protection), durable materials (aluminum alloy/stainless steel casing), and flexible operation (wireless remote control or variable frequency speed control). Explosion-proof electric hoists are suitable for hazardous locations such as the petroleum, chemical, and military industries. With rated loads ranging from 0.25 to 30 tons, they can reach lifting heights of up to 60 meters and typically operate at 380V/50Hz. Combining safety and efficiency, they are an ideal solution for lifting materials in hazardous environments.

Explosion-proof electric hoist manufacturer

Features：

1. Safe and Explosion-Proof, Reliable Operation

Equipped with a flameproof motor and explosion-proof electrical components, this explosion-proof electric hoist complies with international and domestic explosion-proof standards such as ATEX, IECEx, and GB3836. It is suitable for use in flammable and explosive environments (such as the petroleum, chemical, military, and gas industries).

Key components (such as the control box and switches) are explosion-proof, eliminating the risk of explosions caused by electric sparks.

2. Multiple Safety Features for Safe Operation

This explosion-proof electric hoist is equipped with overload protection, limit switches, and an anti-static wire rope/chain to prevent accidents.

High-temperature protection prevents motor overheating and ensures long-term stable operation.

3. High Efficiency and Durability, Suitable for Harsh Environments

The F/H-class insulation motor provides excellent heat dissipation and is suitable for high-load operations.

The aluminum alloy/stainless steel casing is corrosion-resistant and impact-resistant, extending the service life of this explosion-proof electric hoist.

4. Intelligent Control, Precise Lifting

Optional wireless remote control or explosion-proof handle, with an operating range of 10-20 meters, enhances operational flexibility.

Optional variable frequency control enables stepless speed regulation, precise positioning, and reduced vibration.

5. Wide Applicability, Flexible Customization

The explosion-proof electric hoist has a wide load range (0.25-30 tons) and an adjustable lifting height (up to 60 meters) to meet diverse working conditions.

Specific voltage requirements (220V/380V/660V) and explosion-proof rating (gas/dust explosion-proof) can be customized.

Applications：

Explosion-proof electric hoists are designed for flammable, explosive, corrosive, and high-dust environments and are widely used in the following industries:

1. Petrochemical Industry
Refineries, chemical plants, and natural gas processing plants: Used for lifting hazardous materials and equipment such as oil tanks, reactors, and pipelines.
Flammable gas/liquid handling areas: Handling explosive media such as ethylene, propylene, and benzene.

2. Military and Aerospace Industries
Ammunition and gunpowder production workshops: Safely handling explosive raw materials and finished products.
Aerospace fuel storage areas: Hoisting high-risk media such as liquid hydrogen and liquid oxygen.

3. Pharmaceutical and Fine Chemical Industries
Explosion-proof cleanrooms: Used for precise lifting of raw materials and solvents (such as ethanol and acetone).
Dust-proof environments (such as powder production workshops) comply with Ex tD explosion-proof standards.

4. Coal Mining and Mining Industries
Underground gas environments: Suitable for use in explosive gas environments such as coal mines and gold mines (explosion-proof level Ex dI).
Ore processing plants: Hoisting ore and equipment, adapting to high dust conditions.

5. Grain processing and storage
Flour mills and starch mills: Prevent dust explosions (meet IP65 dust and water resistance standards).
Alcohol and edible oil storage tank areas: Material handling requiring strict explosion protection.

6. Shipbuilding and marine engineering
Oil tankers and LNG carriers: Used for hazardous materials loading and unloading, adapting to corrosive marine environments.
Offshore oil platforms: Explosion-proof and salt spray-resistant, ensuring safe operations in harsh climates.

7. Other specialized industries
Lithium battery production workshops (explosion-proof and anti-static).
Paint and coating manufacturing (volatile solvent environments).
Waste treatment plants (methane explosion protection requirements).
