1.  Before working check if the size are suitable and connecting point is stable and reliable.
2.  Forbidden using a bolt or the metal bar instead of screw pin.
3.  Impact during lifting is forbidden.
4.  The screw pin can be running flexible in the lifting hole.
5. It dosen’t allow to bear the curved transverse direction regulation effect on the shackle body. That means the bearing within body flat surface.
6.  When there are different angles on body flat surface, the working load limit should be adjusted accordingly.
7.  The angle of 2 slings under shackle should be less than 120 degree (for example figure to the right).
8.  The shackle musr avoid curving and unsteady loading(picture as follows).

9.  Avoid the partiality loading(picture as follows).
10.  When shackle working with wire rope sling together, the connecting parts should be the shacke’s pin part with the sling eyes. Forbidden using shackle body connecting with the sling eyes.

11.  Reasonble and regular inspection should be taken. According to the frequent use. The inspection cycle should not be less than.
12. Please reconsider the working load limit in case of high temperature:
- six months and the record should be taken down.

Reject the shackle in case of the following situattion:
1.  Remove any place buckling the body and axis pin, should be rejected
immediately when using naked eyes to observ if creacked.
2.  The sackle should be rejected immediately any place of clean wear amounts.
3.  The shackle should be rejected immediately when cracked after magnetic away exceding nominal dimension 10% o’clock face to face removing the button.
particle crack detection and ultrasonic crack detection. body and axis pin, should be rejected immediately.
4.  The shackle should be rejected immediately when body have obvious
5.  The shackle should be rejected when there is a large area of corrosion or rusty deformation, axis pin to have deformation to be able to not rotate. on the body and screw pin.
