Description: Explosion-proof chain hoist is a type of flame-proof chain hoist. Users who have used explosion-proof chain hoists will have a certain understanding of this product. They all know that this type of explosion-proof hoist is used in some special Places such as: mining, petroleum and petrochemical, etc., have explosive and explosive safety hazards and other places to carry out lifting operations. Since explosion-proof hoist has explosion-proof characteristics, it has a lot to do with its production materials. Today we Let's introduce what material the explosion-proof chain hoist is forged from, and what material determines its explosion-proof characteristics?
Explosion-proof electric hoist is an electric hoist with "explosion-proof" characteristics. Users who have used explosion-proof electric hoists will have a certain understanding of this product, and they all know that this explosion-proof hoist is used in some special places such as mining , Petroleum, petrochemical, and other places with explosive safety hazards and other places to carry out lifting operations, since explosion-proof hoist has explosion-proof characteristics, then it has a lot to do with its production materials, today we will introduce explosion-proof What material is used for forging the electric hoist, and what material determines its explosion-proof characteristics?
The materials of explosion-proof electric hoists are mainly bronze and beryllium bronze. Generally speaking, aluminum bronze chain hoists are the most common and most widely used, and beryllium bronze has a higher hardness and is suitable for working hardness above HRC 35 degrees. Gourds are relatively expensive and have better quality. Choose the lifting product that suits you according to your usage.
The characteristics of explosion-proof electric hoist: The good thermal conductivity of copper and the almost carbon-free property make the heat generated in a short time when the lifting tools and objects rub or impact. Furthermore, because copper itself is relatively soft, it has a good concession during friction and impact, and it is not easy to produce tiny metal particles and sparks are not easy to occur. Therefore, it is very suitable for use in explosive, flammable and corrosive places.
Use rules of explosion-proof electric hoist:
1. Overloading is strictly prohibited.
2. The explosion-proof electric hoist lifting chain should be hung vertically, there must be no twisted chain links, and the lower hook rack of the double-row chain must not be flipped.
3. During the hoisting process of the explosion-proof electric hoist, no matter the weight is raised or lowered, the force should be even and gentle. Don't rush to respond to press the switch to avoid the lifting of the chain or the snap ring.
4. After cleaning and maintenance of explosion-proof electric hoist, no-load test should be carried out to confirm that it works normally. When the brake is reliable, it will be explosion-proof. The precautions for using explosion-proof electric hoist can be delivered. When using explosion-proof electric hoist, please read the instruction manual first according to the regulations.
