What Should Be Paid Attention To When Using A Flexible Lifting Sling

BY ADMIN | 27-05-2022

  1. The flexible lifting sling must be inspected before each use. Check whether the surface of the lifting sling is scratched or cut in the transverse direction, from the direction, and whether the edges, soft rings, and end pieces are damaged. Confirm that the lifting sling is good before lifting.

  2. Strictly abide by the lifting method coefficient (see Appendix A), and use the lifting sling correctly.

  3. The surface of the lifting workpiece should be smooth, and there should be no sharp corners, burrs, and edges. For apricots, special sheaths and corner protectors for lifting sling should be used. It is forbidden to directly lift objects with sharp corners, burrs, and edges with a lifting sling.

  4. When hanging directly with a soft ring, the diameter of the support 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 with the hook and loop. If the bandwidth is less than 75mm When it is used, the soft loop can be directly connected to the shackle for suspension, but the curvature radius of the shackle shall not be less than 0.75 of the bandwidth.

  5. Do not 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 hoisting device connected by the soft ring should be smooth without any sharp edges, and its size and shape should not tear the seam or overload the strap.

  7. When moving the lifting sling and the goods, the lifting sling is not allowed to drag anywhere, so as not to damage the surface of the lifting sling.

  8. Do not lift and transport in a knotted or twisted state when carrying.

  9. Lifting sling is prohibited to hang goods for a long time.

  10. When the goods stay on the lifting sling, the lifting sling shall not be pulled out from the loaded state to avoid damage to the lifting sling.

  11. The lifting sling should avoid being caught by other objects or subjected to other impact loads during the lifting process.

  12. The opening angle of the lifting sling soft ring shall not exceed 200.

  13. The load condition shall not be changed during the hoisting process. When several lifting slings need to be used at the same time, put them on each lifting sling as much as possible.

  14. It is forbidden to connect or extend the lifting sling by knotting.

  15. The lifting sling should try to avoid contact with chemicals such as acid and alkali during use, and avoid using it in places with high temperatures and sparks. If the lifting sling is dirty or used in an environment with acid or alkali, it should be rinsed with cold water immediately.

  A. Polyamide (Nylon): It has a moderate corrosive effect on acid; the 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 moderate acid corrosion resistance.

  C. Polypropylene: acid and alkali have little effect on it.

  16. When not in use, the lifting sling should be placed in a special storage rack (place). Lifting slings should not be stacked near open flames, operations with open flames, or other heat sources. Not allowed to be placed in the hot sun for a long time.

  17. After every day of use, the oil stains on the lifting sling should be wiped clean with clean water and placed on a special storage rack.
