Why Is Explosion-proof Electric Hoist More Expensive Than Electric Wire Rope Hoist in 2022?

Why is explosion-proof electric hoist more expensive than electric wire rope hoist

With the rapid development of the industry, the application of explosion-proof hoists is becoming more and more extensive. 

It can be used in flammable, explosive, high temperature, high dust and highly corrosive workplaces such as chemical industry, textile, painting, logistics, docks, etc.;

The electric wire rope hoist is mainly used in industrial and mining enterprises, railways, docks, warehouses, stockyards and other places.

Although many customers engaged in chemical industry, textile and other industries are already using explosion-proof hoists, the specific difference between the two has not been fully summarized for a while.

When buying explosion-proof electric hoists, some customers think that there is no difference in structure and configuration between these two types of hoists, 

and explosion-proof electric hoists are only explosion-proof, and there is no difference between them and other hoists.

Then this article will explain to you in detail the advantages of explosion-proof electric hoists and the differences between the two:

The first is the advantages of explosion-proof electric hoist:

1. It has the characteristics of high frequency and infinitely variable speed.

It is deeply favored by the automobile, motor, refrigerator and other manufacturing industries and the logistics industry with large output and strong continuous operation.

Especially in flammable and explosive places such as petroleum, chemical industry, automobiles, and mines, the state requires the use of explosion-proof hoists.

2. It can avoid electrical conduction and mechanical friction during operation, and avoid possible arcs, sparks and overheating.

3. Explosion-proof electric hoist is a complete set of electromechanical equipment composed of explosion-proof electrical equipment, metal structure, mechanism 

and parts, explosion-proof electrical parts connection, mechanical or hydraulic transmission and safety devices.

Secondly, the explosion-proof requirements of explosion-proof electric hoists:

1. High temperature and sparks generated by a single explosion-proof electrical equipment should be considered when using;

2. Consider mechanical sparks and high temperatures due to frictional impact of mechanical moving parts.

Finally, the basic explosion-proof principle of explosion-proof electric hoist:

Its principle is to take some relevant measures. It is necessary to control the generation of sparks and arcs to a certain extent, 

and use corresponding explosion-proof technology to control and eliminate electrical sparks 

and mechanical sparks so that they cannot ignite in the environmental area where they are located. explosive gas mixture.

So, what is the difference between explosion-proof electric hoist and electric wire rope hoist?

Because the explosion-proof electric hoist is used in flammable and explosive environments, 

its main accessories are also explosion-proof, not only the shell is explosion-proof, but its hoisting mechanism and running motor are explosion-proof. 

The motor protection class is IP55, and the insulation class is F. The ordinary steel wire rope is IP44 and the insulation grade is B.

The following is a brief introduction about explosion-proof electric hoist:

The explosion-proof electric hoist is a kind of explosion-proof lifting equipment designed and manufactured according to the explosion-proof standard. 

Its explosion-proof form is "explosion-proof type".

The explosion-proof electric hoists produced by our company have passed the explosion-proof performance inspection of the explosion-proof electrical product quality supervision 

and inspection of the Ministry of Machinery Industry, and have become one of the most popular products in Dejun lifting, with a large number of customers and market demands.

Explosion-proof electric hoist is suitable for Class I explosion-proof coal mine non-excavation working face and suitable for Class II explosion-proof with grades IIA, IIB, IIC, 

and the temperature group is T1-T4 group. Combustible gas or explosive gas mixture composed of steam and air place. The working environment temperature is -25℃~40℃, 

which is suitable for indoor use; when used outdoors, protective devices are required.
