Single Girder Eot Cranes

Single girder eot crane

 

 

Single girder eot cranes is composed with Girder frame, Crane travel device, and the trolley with lifting and moving device. There are Pave the rail for the trolley move on the main girder.

 

Assemble the moving table on the outside of the two main girder, one side is prepare for the assemble and maintenance the crane move device, another side is prepare for the assemble of the trolley conductor device.

 

There are full field of view Cabin suspend under the main girder, there are joint control desk or single control box packed within the Cabin, assemble the sidelong ladder between the Cabin and moving table, The main girder joint with the two side end carriage which with the joint point in the middle.

The technical features of the Single girder eot cranes 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.

 

Single girder eot cranes 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 Single girder eot 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 Single girder eot cranes 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.

 

Single girder eot cranes 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.
