Why Is Explosion-Proof Electric Hoist More Expensive Than Ordinary Hoi

When some customers buy, many people are not very clear about the difference in structure and equipment between explosion-proof electric hoist and wire rope electric hoist. They just think that the explosion-proof electric hoist can be explosion-proof, in addition to other electric hoists Crane factory. There is no difference.

Then the question came, the price distance is so large, is it because the manufacturer's price is too high, and there is doubt? In addition, because the explosion-proof electric hoist itself is used in flammable and blasting environments, its main accessories are also explosion-proof, not only the shell is explosion-proof, so the price will be higher than the wire rope electric hoist. In the next step, we will give you a specific introduction to the equipment of the explosion-proof electric hoist:

1. Use explosion-proof motors;

The improved organization of the explosion-proof electric hoist and the running motor are all explosion-proof, with a grade of ExdⅡCT4. Motor maintenance grade IP55, insulation grade F. Compared with IP44 and general steel wire rope, the insulation grade is B grade.

2. Use explosion-proof hooking equipment.
