What should we pay attention to when using lifting hooks?
There are always many things that need to be paid attention to when using lifting hooks. Below, let’s take a look at what specific things we need to pay attention to!
Things that should be paid attention to when using lifting hooks are:
1. The surfaces of hooks and rings should be smooth, and they should be inspected after 1 to 3 years of use.
2. When a dangerous part of the hook is found to be worn more than 10%, its load should be reduced. Hook load test: A heavy object with 125% of the rated weight is suspended for 10 minutes. After unloading, measure the hook mouth. If there is permanent deformation and cracks, it should be renewed or reduced in use.
3. The hook needs to be replaced immediately under the following circumstances:
(1) Use a 20x magnifying glass to observe the surface and find cracks or breaks.
(2) Load testing produces long-term deformation.
(3) There are deformations and cracks in the hook tail and thread parts.
(4) Fatigue cracks at the transition fillet between the threaded part and the non-threaded part of the hook tail.
