- Operation guide
1. Befor using, we should know the WLL and scope of application. Over loading is not allowed.
2. The lifting angle is the key point to influence the WLL under normal situation. The angle in dashed area of the picture should not be bigger than 120 degrees, otherwise part of the chain slin will be over loaded.
3. Unavailabel connector between the chains is not allowed.

3. Unavailabel connector between the chains is not allowed.
4.The lifting chain should not be hung directly or enwind to the lifting hook of the crane.
5.When chain slings enwind the lifted object, please lay some pads on the corner to avoid damaging of the chain and lifted object.

6. Temperature can effect the using of the chain slings:
7. The hoisting point of the lifting hook of the crane should be in the same line of the lifted object, thus the stressed area keep balance to avoid slipping and overturning.
8. Torsion, tortuosity, knot are not allowed between links.
9. When lifting the heavy object, up, down and stopping slowly and stady. Be sure to keep the cg of the lifted object and avoid impacting loading WLL. Hanging heavy lifted object in the sling chain for a long time.

10. One leg chain sling and multi legs chain sling can be usedas choker chain sling when ther is not suitable lifting hook, lug and link. If
If the lifted objectis bulk cargo such as tube and log , we can use the chain enwind one more lap.
11. We should be careful when taking and laying the chain slings.Koncking the chain slings or drawing the sling the sling on the ground
12. The chain sling should be cleaned and tested after using. We should put it in the appropriative shelf rather than the ground.
13. Don’t attempt to pull the chain sling from the lifted object or roll the lifted object on the chains.

1 The dia of the link is frayed to be 90% of normal state, that means the dia is frayed by 10%, now we should change the part or stop using.
2 The outside lenght of the chain increased by 5%, now we should change the part or stop.
3 . Eyes or other examening equipments find the welding gap of the link or other destroyes chains, we shoul change the part or stop using..

4. Contoring, badly corrosion and begriming can not be removed, or the dangerrous cross section of the fittings reduceby 10%.
5. The pich of singel link streched 3% or more, pich of double link stretched 5% or more.
6. Stop using when the chain slings destroyed by heat source.
