The ratchet tie down is made of synthetic fiber industrial yarn. Its advantage is that the texture is soft and does not hurt the surface of the hanging object. The disadvantage is that it is easily cut by the sharp edges of the goods.
I saw a user asking on the Internet that he said that the flat ratchet tie down he bought was interrupted during the hoisting process. I don't know what happened. Can we judge whether the ratchet tie down is cut or pulled by the marks of the break? If the quality is not good, it may be negotiated with the ratchet tie down 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. Cargo control hardware manufacturers will tell you the reasons for these two types of fractures and the fracture edges. form of presentation.
The condition and traces of ratchet tie down:
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 ratchet tie down is cut or ground to show traces: although the fracture surface of the ratchet tie down is not particularly flush, it is also a relatively uniform port, which is as neat as cutting with a knife.
How to avoid: When the lifting object has sharp edges, these sharp edges will bring destructive cuts to the ratchet tie down. To protect the synthetic fiber ratchet tie down from cuts, a protective lining can be used on the ratchet tie down and the ratchet ties down. between the hanging objects.
Reasons and traces of ratchet tie down:
In the case of breakage, it may be that the quality of the purchased synthetic fiber ratchet ties down 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 filament 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 ratchet tie down is easy to identify on the fracture marks when it is cut or pulled. If the used ratchet tie down breaks, you can analyze how the ratchet tie down breaks according to the above fracture marks. If you use the ratchet tie down without overloading, and the objects you are hanging are rounded and angular, it must be that the quality of the ratchet tie down is not good enough. You can directly ask the manufacturer for compensation if you keep the site!
