It is mainly suitable for flammable and explosive environment:

1)  Below 1000 meters above sea level

2) The ambient air temperature is not higher than +40℃, not lower than -20℃

3) The fluctuation of power network is ±10%

4) The relative humidity is not more than 95%, can prevent dripping occasions

 

 

1) Light weight, small size and large lifting capacity;

2) Adopt G80 carbon black alloy steel chain, high strength bearing capacity;

3) All electrical circuits and other components are concentrated in the explosion-proof box for isolation and explosion-proof;

4) Can be customized according to customer needs

 

 

1. I beam (straight line or curve line)
2. Overhead crane
3. Gantry crane
4. Jib crane

 

 

 

 

1. Which places need to use Explosion proof electric chain hoist?

It uses in hazardous locations with explosive gases and explosive mixtures of vapor and air, such as mining, chemical, pharmaceutical and other industries.

 

2. What is the lifting capacity for the Explosion proof electric chain hoist?

The common capacity are 1t, 2t, 3t, 5t, 10t, for more heavier capacity, please advise and we will check.

 

3. If the explosion proof electric chain hoist can be used on my jib crane?

Yes, they can be install on jib crane, and also for overhead crane

 

4. What do explosion-proof appliances need?

To meet the explosion proof rating standards, the housing must be able to contain any explosion originating from its housing and prevent sparks from its housing from igniting steam, gas, dust or fibers in the surrounding air.

 

5. What is the main difference between explosion-proof chain hoist and ordinary electric chain hoist?

1) The motors are different. The lifting motor and running motor of the explosion-proof electric chain hoist are explosion-proof, explosion-proof grade Don’t be Ex d Ⅱ B T4 or Ex d Ⅱ C T4 (the meaning of explosion-proof level is explained in detail in other articles). electricity Machine protection class IP55, insulation class F. The motor protection grade of ordinary electric chain hoist is IP54.

2) The electrical box and the handle switch are different. The electrical box and the handle switch of the explosion-proof electric chain hoist are explosion-proof Yes, the volume is larger than ordinary ones, and the sealing performance is better. Compared with ordinary ones, the handle switch is also stronger and more resistant Water performance is stronger.

3) The explosion-proof lower hook is different. When it comes to explosion-proof, our lower hook is to be replaced with an explosion-proof hook of. Generally, special customized hooks are used in IIC (this can be confirmed in actual order).

4) The overall electrical and electrical boxes are marked with Ex explosion-proof marks.

5) If it is a running electric chain hoist, the wheels of the sports car are also different, and they all need to be explosion-proof Grade to match the wheels.When to choose to use explosion-proof electric hoist? Generally, when using explosion-proof hoists, there are clear requirements. Compared with the need for motor explosion-proof or electrical explosion-proof, or the gas in our explosion-proof grade appears in the customer's working conditions.

 

6. Can the explosion-proof hoist be overloaded?

Overloading will break the chain and cause heavy objects to fall quickly, resulting in serious safety accidents. Please be careful not to overload.

 

7. Can you customize my brand color?

Yes, we can. But it has minimum quantity requirement.

 

8. Is explosion-proof hoist is safe enough?

Sure, please operate it according to our instruction manual and do not proceed common faults.
