Why is the explosion-proof electric hoist more expensive than


When some customers buy, many people are not sure what is the difference between the structure and configuration of the explosion-proof electric hoist and the wire rope electric hoist. It is simply that the explosion-proof electric hoist can be explosion-proof, and there is no difference between it and other hoists. Then the problem has come, the price gap is so big, is it that the price reported by the manufacturer is too high, and I am worried about it. In fact, the explosion-proof electric hoist is used in the flammable explosive environment. The main accessories are also explosion-proof. It is not the outer casing explosion-proof, so the price will be higher than the wire rope electric hoist. Below we will explain in detail the configuration of the explosion-proof electric hoist:

1. Use explosion-proof motor. The hoisting mechanism and running motor of the explosion-proof electric hoist are explosion-proof and the level is ExdIICT4. Motor protection class IP55, insulation class F. The ordinary wire rope is IP44, and the insulation grade is B.

2. Use an explosion-proof hook. The three-stage explosion-proof hook is a common hook, but there is a copper piece at the rope exit of the hook pulley. On the basis of the four-stage explosion-proof hook, it was replaced with a stainless steel hook.

3. The electrical box and handle used are explosion-proof. Compared with wire rope hoists, the explosion-proof hoist electrical box is bulky, heavy, and the handle is stronger and more waterproof. 3, the use of explosion-proof fire stop limiter. The surface has an EX explosion-proof mark.

4. The rope guide and running wheel are explosion-proof. The rope guide and running wheel of the three-stage explosion-proof hoist are the same as the ordinary wire rope hoist, and the four-stage explosion-proof hoist rope guide and running wheel are explosion-proof.

5, size and weight. The size of the explosion-proof hoist is longer than that of the ordinary steel 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 five points, we will definitely understand why the explosion-proof electric hoist can be explosion-proof, and there will be a new understanding of the explosion-proof electric hoist, which will also help your purchase. Here to remind everyone, the price level does not indicate the quality of the product, but can not choose some unknown small manufacturers because of the preferential price on the price, then the after-sales is a big problem!
