Precautions For The Use Of Flexible Slings
Oct 24, 2023
1. The flexible sling must be inspected before each use. Check whether the surface of the sling is scratched or cut laterally, from the direction, and whether the edges, soft loops and end pieces are damaged. Confirm that the sling is in good condition before lifting.
2. Strictly observe the hoisting method coefficient and use the sling correctly.
3. The surface of the lifting workpiece should be smooth, without sharp corners, burrs and edges, otherwise, a special sheath and corner protection for slings should be used. It is forbidden to directly lift objects with sharp corners, burrs and edges with slings.
4. When the soft ring is used for direct hanging, the diameter of the support member should not exceed 1/3 of the inner length of the soft ring. If the bandwidth is greater than 75mm, the soft ring should not be directly connected to the hook for hanging, if the bandwidth is less than 75mm When using a soft loop to directly connect with the shackle, but the radius of curvature of the shackle shall not be less than 0.75 of the bandwidth.
5. It is not allowed to use the bolted lifting method without protection in a concentrated manner.
6. Do not connect the soft ring with any device that may cause damage to it. The lifting device connected by the soft ring should be smooth without any sharp edges, and its size and shape should not tear the sutures or make the belt overloaded. .
7. When moving the sling and cargo, the sling is not allowed to be towed anywhere, so as not to damage the surface of the sling.
8. Do not hoist in a knotted or twisted state during loading.
9. It is forbidden to hang the cargo on the sling for a long time.
10. When the cargo stays on the sling, the sling shall not be taken out from the load-bearing state, so as not to damage the sling.
11. The sling should be prevented from being hung by other objects or subjected to other impact loads during the lifting process.
12. The opening angle of the soft loop of the lifting strap shall not exceed 200.
13. The load condition must not be changed during the lifting process. When several slings need to be used at the same time, put them on each sling as much as possible.
14. It is forbidden to connect or extend the sling by knotting.
15. When using the strap, try to avoid the contact of acids, alkalis and other chemicals, and avoid using it in places with high temperatures and sparks. If the sling is dirty or used in an acid or alkali environment, it should be rinsed off with cold water immediately.
A. Polyamide (nylon): It has a medium-strength corrosive effect on acids; its strength is reduced by about 15% in a humid environment; it is not affected by alkali; ultraviolet rays will accelerate its aging.
B. Polyester (PES): It will be damaged in alkali; it has medium acid corrosion resistance.
C. Polypropylene: Acid and alkali have little effect on it.
16. When not in use, the sling should be placed in a special storage rack (place). Slings should not be stacked near open flames, open flame operations or other heat sources. Do not leave it under the scorching sun for a long time.
17. After using it every day, wipe the greasy dirt on the sling with clean water and place it on the special storage rack.
