How to Choose the Right Type of Explosion-Proof Crane?
With the development of social economy, explosion-proof cranes are more and more used in various dangerous places such as power plants, chemical plants, coal mines, and military enterprises. These dangerous places are either explosive gas environments or combustible dust environments. Open flames can easily ignite explosive gases or combustible dust, causing casualties and equipment damage accidents, and causing losses to the country and people's lives and property.
First of all, what needs to be ruled out is the selection error at the time of purchase. You must know that there are many types of explosion-proof cranes.
20 ton Explosion-proof cranes can be divided into the following three categories according to the corresponding use environment:
Class III (cranes for combustible dust environments) is divided into two types, Type A and Type B, according to the dust-proof ability of electrical equipment, represented by DIPA and DIPB respectively.
At present, in some military industries, fireworks and firecrackers, coal preparation plants, food processing plants, cotton processing plants and other enterprises, 15 ton explosion-proof cranes used in explosives, explosive dust, and fiber environments should choose explosion-proof cranes for combustible dust environments. However, due to malicious competition from suppliers, the explosion-proof bridge cranes used by most customers are all explosion-proof grades of dⅡCT4 electrical equipment for explosive gas atmospheres. The standard requirements for gas explosion protection and dust explosion protection are different and cannot replace each other.
Therefore, in order not to bury congenital safety hazards for future safe use and maintenance, please be sure to describe the working conditions of the crane when purchasing an explosion-proof bridge crane, and be sure to choose a responsible and experienced manufacturer.
