Industrial Eot Crane

Industrial Eot Crane

 

Electrical conduction and mechanical friction are produced along with mechanical operation, and phenomena such as arcs and sparks will also be formed during high-intensity work. In order to avoid arcs and sparks from igniting flammable and explosive materials, explosion-proof industrial eot cranes are required in environments where flammable and explosive materials need to be handled.

The technical features of the explosion-proof industrial eot crane can prevent the formation of arcs, sparks and overheating, even if formed, it will not ignite explosives. Its explosion-proof technical characteristics include mechanical structure, design and production.

 

Explosion-proof bridge crane is a combination of explosion-proof electrical equipment, explosion-proof metal structure, explosion-proof parts, explosion-proof machinery or hydraulic transmission.

 

In terms of the technical requirements of explosion-proof overhead cranes, the high temperature and frictional sparks formed during the operation of a single explosion-proof electrical equipment must be considered first, and the mechanical sparks and high temperature formed by the frictional impact of the mechanical moving part are secondly considered.

 

The basic explosion-proof theory of explosion-proof industrial eot crane is to control the formation of sparks and arcs within the standards that meet the working environment through partial transformation, directly eliminate or properly suppress the generation of electrical sparks and mechanical sparks, so that sparks and arcs cannot reach conditions to ignite explosive gases in the environment. In most cases, the relevant explosion-proof technology of explosion-proof bridge cranes includes two types of electrical explosion-proof technology and mechanical explosion-proof technology.

 

Industrial eot crane is mainly used in coal mining, oil and gas, petrochemical, chemical and other industries. In addition, it is widely used in textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, medicine and other sectors. As the primary power equipment, explosion-proof motors are usually used to drive transmission machinery such as pumps, fans, and compressors.

 

 

Specification requirements

 

1. When lifting, it is necessary to clean up the surrounding area, and do not pile up debris around it, which will affect the operation of the explosion-proof crane.

 

2. The 10-ton explosion-proof industrial overhead crane is best to lift about 10 tons of cargo, and do not overload it.

 

3. The chain of the electric hoist should be lubricated in time and regularly to prevent the chain from rusting.

 

4. Do not pull it obliquely, lift it vertically during lifting work, and pulling it obliquely will cause the danger of overload.

 

Chemical plants are different from ordinary factories, and special attention should be paid to the use of explosion-proof electric hoists.
