    How to check if the explosion-proof chain hoist is qualified


Description: Explosion-proof chain hoist is a product used in special fields. Explosion-proof chain hoist is made of bronze. The rotating gear is heat-treated at high temperature to achieve high wear resistance. Choosing explosion-proof products is more cautious than choosing ordinary products. Below is a summary of how to check whether the explosion-proof chain hoist is qualified?
Explosion-proof chain hoist is a product used in special fields. Explosion-proof chain hoist is made of bronze. Its rotating gear is heat-treated at high temperature to achieve high wear resistance. Choosing explosion-proof products is more cautious than choosing ordinary products. Below is a summary of how to check whether the explosion-proof chain hoist is qualified?
1. From the appearance, each part of explosion-proof chain hoist should be made well, there should be no defects that affect the use, and there should be no scars or burrs on the appearance. The exposed surface of the explosion-proof chain hoist should be rust-proofed, the coating should be uniform, the color and luster should be consistent, and there should be no rust.
2. What needs to be detected is that when the explosion-proof chain hoist is not load-bearing, pull the zipper strip by hand, the sound should be crisp and pleasant, and the rules should be flexible, and there should be no jamming or loosening for a while. Tight phenomenon appears ...
3. Check its dynamic load performance under load, and perform one lifting operation and one lowering operation within a certain lifting range. Each component should meet the following requirements: lifting chain and lifting sprocket, cruise ship, hand The zipper bar meshes well with the bracelet wheel without jamming; the gear pair runs smoothly without abnormalities; there is no kinking in the lifting chain during lifting and lowering; the pull force should not change significantly when lifting; the brake action is reliable . The brake includes: a complete set of brake pads, a base, a pawl, a ratchet wheel and the like.
4. Static load experiment and dynamic load experiment. A qualified explosion-proof chain hoist should be able to withstand four times the static tensile load, which means that an explosion-proof chain hoist with a rated load of one ton should be able to withstand four times the static tensile load. Dynamic load performance is required to be able to withstand 2.5 times the dynamic tensile load.
