Shackles

Description：

Shackles are commonly used connecting equipment in construction, mechanical engineering, rigging and lifting, etc. Commonly, shackles can divide into mainly two types which are bolt type and screw pin type and some special types, like “twist”, “flat”, “long reach” and so on. The bolt type shackles has a more generous loop better suited to multiple connection; and the screw pin type is widely used in tightening.

In the rescue operation, the shackle is usually called the connecting ring, which is the necessary connection equipment between the wire rope and wire rope, wire rope and the car body, the wire rope and the pulley, and the rigid traction frame and the car body, etc. According to different uses, the form of connecting ring is also different, commonly used are D-shaped connecting ring, double D-shaped connecting ring, connecting sleeve and so on.

4. Working breaking load: we can customize the shackle parameter according to your needs.

5. Size: we can customize the shackle parameter according to your needs.

6. Color: we can customize the shackle parameter according to your needs.

The knowledge of shackles:

1. Carefully check its bearing capacity, whether the appearance is deformed or damaged, and whether the connection part is in good condition to prevent problems.

2. The allowable load of the shackle can be estimated by the following formula according to the diameter of the pin: Q=0.0035d²

Q (KN)——the estimated allowable load of the shackle;

d (mm)——The diameter of the pin of the shackle.
