Release time: 2018-02-07

How to use the shackle and precautions:

1. Before operation, check whether the type of shackle used is matched and whether the link is firm and reliable.

2. It is forbidden to use bolts or metal rods instead of pins.

3. No large impact and collision are allowed during the lifting process.

4. The pin should rotate flexibly in the bearing hole, and no jamming is allowed.

5. The shackle body shall not bear the effect of lateral bending distance, that is, the bearing capacity shall be within the plane of the body.

6. When there are different angles of bearing capacity in the body plane, the maximum working load of the shackle is also adjusted.

7. The maximum angle between the two-leg rigging carried by the shackle is 120 degrees in heavy rain.

8. The shackle should support the load correctly, that is, the force should be along the center line of the shackle, avoid bending, unstable load, and not overload.

9. Avoid the eccentric load of the shackle.

10. When the shackle is used with the wire rope rigging as a help rigging, the horizontal pin part of the shackle should be connected with the eyelet of the wire rope rigging, so as to avoid friction between the wire rope and the shackle when the rigging is lifted, causing horizontal The pin rotates, causing the horizontal pin to disengage from the button.

11. According to the frequency of use and bad working conditions, Chengdu should determine a reasonable regular inspection. The period of regular inspection should not be less than half a year, and the longest should not exceed one year, and make an inspection record.
