The following picture and drawing of the C-hook for your reference.

C-hook

Drawing

Main structure：

• The main structure of C-hook is composed of hook body and counterweight iron:
• Hook body: The main part of the c-shaped hook is spliced by steel plate (high-quality low-alloy steel) and steel pipe. The cross-section is a box-shaped structure, which has good resistance to bending and torsion. The spreader is light in weight and has a long service life. .
• Counterweight iron: play a role in adjusting the balance of the spreader, so that the hook and the suspended object are in a line

Daily maintenance:

• C-type hooks are not allowed to be stored in high temperature areas.
• The used c-type hook must be placed on a special shelf, stored in a ventilated, dry, and clean workshop, and kept by a dedicated person.

• Crack
• Dangerous section wear reaches 10% of the original size;

• The torsion deformation of the hook body exceeds 10°;
• Plastic deformation of the dangerous section of the c-shaped hook or the neck of the hook;
• The hook thread is corroded;
• When the blade hook bushing wears up to 50% of the original size, the bushing should be replaced;
