Explosion Proof Electric Chain Hoist

Explosion proof electric chain hoist is a light and small lifting equipment. The explosion proof electric chain hoist has light weight, small volume and large lifting capacity. When the factory is filled with explosive mixture, it is to improve working conditions and improve labor productivity under the premise of ensuring safety. A good tool is the necessary mechanical equipment for production.

Explosion proof electric chain hoist is an explosion proof lifting equipment designed and manufactured by China's latest explosion proof standard. Its explosion proof form is “explosion-quarantine type”. The exposed explosion proof parts of the hoist are made of special non-sparking materials, and the explosion proof performance is safe and reliable. The product passed the explosion proof performance test of the explosion proof electrical product quality supervision and inspection center of the Ministry of Machinery Industry, and issued an explosion-proof certificate.

Explosion proof electric chain hoist structural characteristics:

1. Explosion proof electric chain hoist is composed of several parts that can be disassembled separately. It is very convenient to use, maintain and overhaul, and can shorten the maintenance period.

2. Its explosion proof motor and explosion-proof control box are separate flameproof structures. Control buttons, limit switches, and explosion proof lifting weight limiters meet the relevant explosion proof requirements.

3. The parts are highly versatile and interchangeable.

4. The reducer adopts standard modulus cylindrical gear for easy maintenance.

Explosion proof electric chain hoist range:

Applicable to the non-mining working face of Class I explosion proof coal mines and the place where it is applicable to Class II explosion proof IIA, IIB, IIC, temperature group T1-T4 flammable gas or explosive gas mixture composed of air and air. The working environment temperature is -25 ° C ~ 40 ° C, suitable for indoor use; when used outdoors, you need to add protective devices.

Explosion proof electric chain hoist explosion proof points:

1. The electrical components of the electric hoist include: lifting and running motor, control box, control button, limiter, etc., all adopt self-contained explosion proof equipment.

2. Adopt a soft cable power introducer.

3. The mechanical components adopt explosion proof measures. In order to prevent the friction of the electric chain hoist during operation, the impact generates high-temperature sparks and the relevant components are treated.

(1) Inject a proper amount of mechanical oil into the hoisting and running gear unit.

(2) Apply grease to the reel and wire rope.

(3) The left and right stop blocks on the limit rod and the stopper sleeve of the stopper are made of bronze or stainless steel.

4. The surface temperature of the explosion proof electric hoist during normal working time does not exceed 110 °C.
