Explosion Proof Electric Hoist

Product description

Explosion proof electric hoist is a lifting device specifically designed for use in flammable and explosive environments. Featuring explosion-proof characteristics, it can operate safely in hazardous locations such as petroleum, chemical, and mining industries. Its core feature involves the use of explosion-proof motors and electrical components to prevent sparks or high temperatures that could cause an explosion. Explosion-proof electric hoists are generally categorized into wire rope and chain types. The chain type is often more suitable for harsh environments due to its compact structure and good sealing.

Main specification

• Explosion-proof Rating: Select the appropriate rating (e.g., Exd IIB T4 or higher) based on the specific environment.

• Lifting Capacity: 0.25 to 10 tons; a 20% safety margin is recommended.

• Lifting Height: 3 to 30 meters or customized.

• Duty Cycle: Consider continuous duty (S4) or intermittent duty (S3).

Technical Parameter

Structure

Explosion-proof electric hoists are based on ordinary wire rope electric hoists, with explosion-proof measures taken for the motor, electrical appliances and some components. According to different environments, they are divided into gas explosion-proof and dust explosion-proof.

The working principle of an explosion-proof electric hoist involves an electric motor driving a chain or wire rope drum to lift and lower loads. Its explosion-proof performance is primarily achieved through flameproof enclosures, increased safety electrical components, or intrinsic safety circuit designs, complying with national explosion-proof standards (e.g., GB3836).

Case

Application

• Petrochemical Industry: In refineries, chemical plants, and other environments with flammable gases.

• Underground Coal Mines: Environments with combustible gases like methane.

• Dusty Environments: Such as flour mills, aluminum powder processing plants, and other locations with explosive dust.
