    Why is the price of explosion-proof electric hoist so expensive?


Description: When some customers buy explosion-proof electric hoist, they may not know what is the difference between the structure and configuration of explosion-proof electric hoist and ordinary electric hoist. They simply think that explosion-proof electric hoist is explosion-proof, in addition to other Gourd makes no difference.
When some customers buy explosion-proof electric hoist, they may not know what is the difference between the structure and configuration of explosion-proof electric hoist and ordinary electric hoist, but they simply think that explosion-proof electric hoist is explosion-proof. Any difference.
Then the problem comes. The gap in prices is so large. Is it because the price quoted by the manufacturer is too high, and I am worried. In fact, because explosion-proof electric hoists are used in flammable and explosive environments, various accessories are also equipped with explosion-proof performance, not just explosion-proof casing, so the price will be higher than ordinary electric hoists. Here we explain the configuration of explosion-proof electric hoist for everyone:
1. Use explosion-proof motor.
The hoisting mechanism and running motor of the explosion-proof electric hoist are explosion-proof, and the grade is ExdⅡCT4. Motor protection class IP55, insulation class F. The ordinary steel wire rope is IP44 and insulation class B.
2. Use explosion-proof lower hook.
The third-level explosion-proof lower hook is a common lower hook, but there is a copper sheet at the rope exit of the hook pulley. On the basis of the four-level explosion-proof lower hook, a stainless steel hook head was replaced.
3. The electrical box and handle used are explosion-proof.
Compared with wire rope hoists, explosion-proof hoist electrical boxes are larger, heavier, handles are stronger, and more waterproof.
Why is the price of explosion-proof electric hoist so expensive?
3. Use explosion-proof fire-stopper. The surface has the EX explosion-proof mark.
4. Rope guides and sports car wheels are explosion-proof.
The three-stage explosion-proof hoist rope guide and sports car wheel are the same as the ordinary wire rope hoist. The four-stage explosion-proof hoist rope guide and sports car wheel are explosion-proof.
5. Size and weight.
The size of the explosion-proof hoist is longer than that of the ordinary wire rope. The size of the upper limiter and the control box are larger than the ordinary wire rope hoist, and the weight is much heavier than the ordinary hoist.
I believe that through the above points, everyone will definitely understand why the price of explosion-proof electric hoists is so expensive and why they can be explosion-proof. There will also be a new understanding of explosion-proof electric hoists, which will also help you when buying. Here I would like to remind everyone that the level of the price does not indicate the quality of the product, but it is also impossible to choose some unknown small manufacturers because of the preference for the price, then the after-sales is a big problem!
