How To Distinguish Whether The Lifting Sling Fracture Is Cut Or Pulled

BY ADMIN | 26-08-2022

  The lifting sling is made of synthetic fiber industrial yarn. Its advantage is that the texture is soft and does not hurt the surface of the object to be lifted. Its disadvantage is that it is easily cut by the sharp edges of the cargo.

  I saw a user on the Internet asking, he said that the flat lifting sling he bought was interrupted during the hoisting process. If the quality is not good, it may be negotiated with the lifting sling manufacturer for compensation.

  For experienced hoisting and hoisting masters, it can be recognized at a glance whether it was cut by a sharp edge or pulled by itself through the fracture marks. Let us tell you the reasons for these two types of fractures and the display form of the fractured edge.

  Conditions and marks of lifting sling:

  Severing is because there are already some wounds on the surface that affect the inner continuity of the filaments. When under tension, both sides of the wound are continuously subjected to external force, resulting in the cutting phenomenon, which is caused by human error operation.

  The lifting sling is cut or ground to show traces: although the fracture surface of the lifting sling is not particularly flush, it is also a relatively uniform port, which is as neat as cutting with a knife.

  Avoidance method: When the lifting object has sharp edges, these sharp edges will cause destructive cuts to the lifting sling. To protect the synthetic fiber lifting sling from being cut, a protective lining can be used between the lifting sling and the object to be lifted. between.

  Reasons and marks of lifting sling breakage:

  In the case of breaking, it may be that the quality of the purchased synthetic fiber lifting sling is not good enough, and it does not reach the specified safety factor, or it may be that the user is overloaded and the synthetic fiber is broken.

  Breaking traces show traces: The synthetic fiber filaments at the fracture will be uneven and obvious, and the difference in length may even exceed 15 cm.

  Summary: The lifting sling is easy to distinguish from the fracture marks when it is cut or pulled. If the used lifting sling breaks, you can analyze how the lifting sling breaks according to the above fracture marks. If you use the lifting sling without overloading, and the objects being lifted are rounded and angular, it must be that the quality of the lifting sling is not good enough. You can directly find the cargo equipment factory for compensation on the spot!
