In Which Occasions, The Chain Hook Should Be Scrapped?
- Cracks by visual check;
- The wear of dangerous section reaches 10% of the original size;
- Hook opening is 15% more than the original size;
- The torsional deformation of hook body exceeds 10 °;
⑤ Plastic deformation of the dangerous section of the hook or the neck of the hook;
⑥ The hook thread is corroded;
⑦ Replace the bushing when the wear of the hook bushing reaches 50% of the original size;
⑧ When the wear of the disc hook mandrel reaches 5% of the original size, the mandrel shall be replaced.
All the chain hooks have three dangerous sections, which should be paid special attention during inspection. As shown in the below schematic diagram, the three dangerous sections of the chain hook are:
- On the one hand, section A-A is affected by the tension of the sling, and the hook tends to be straightened; On the other hand, it is also affected by bending moment. Because the bending moment acting on this section is the largest and the bending stress is the largest, this section is a dangerous section.
(2) Section B-B is the same as section A-A. section B-B tends to be straightened and cut under the action of sling tension. The shear stress here is the largest, so it is also a dangerous section.
(3) C-C section, which is the thinnest part of the hook column, tends to be pulled off under the tension of the sling. The tensile stress here is the largest, so it is also a dangerous section.
