Lift shackles are critical components in material handling, lifting, and rigging operations. Selecting the right shackle is essential to ensure safety, efficiency, and durability in various applications.The main types of Shackles include the following.
- US Type S6 grade shackle
- Flat Shackle
- Large Shackle
- Grade T8 Shackle
Shackles Product Features:
- The body of the shackle is made of alloy structural steel forged and heat-treated, with small volume and high strength.
- The test load of the shackle is 2 times the ultimate working load, and the breaking load is 4 times the ultimate working load. (Higher than 4 times the safety coefficient can be special production)
Uses of shackles：
1、Shackles are mainly used for rigging end fittings, which are directly connected to the lifted object during lifting operations.
2、When the rigging is used in conjunction with a crossbeam, shackles can be used at the top of the rigging instead of rings to connect to the lower lugs of the crossbeam for ease of installation and removal.
3、Type D shackles are mainly used for single-limb rigging; Type B shackles are mainly used for multi-limb rigging.
The Proper Use Of Shackles：
1、When shackles are used, attention must be paid to the direction of the force acting on the shackles structure, if it does not meet the force requirements for use, it will make shackles allow the permissible limit of the working load is greatly reduced.
2、Proper use of shackles with single limb rigging installation:
Notes On Using Shackles:
- The limit working load and applicable range of shackles are the basis of test and use of shackles, overloading is strictly prohibited (the same applies to other products, and will not be repeated). 5.3 The lifting process should be as smooth as possible.
- During the lifting process, it is strictly prohibited to subject the lifted objects to collision and impact (the same applies to other products, which will not be repeated later).
- The lifting process should be as smooth as possible, and it is strictly prohibited to stand underneath or pass on the articles (the same applies to other products, and will not be repeated later).
- Any one of the shackles must be tested before use and then lifted. Selection of lifting point should be with the centre of gravity of the lifted object in the same plumb line (the same applies to other products, will not be repeated)
- The thickness of the lifting lugs and other rigging fittings in contact with the pin of the shackles shall be not less than the diameter of the pin.
Lifting Shackles End-Of-Life Criteria:
The product should be replaced or scrapped if any of the following conditions occur：
- When the shackles buckle body is twisted more than 10°.
- When the corrosion and wear exceeds 10% of the nominal size.
- When there are cracks in the shackles and pins after flaw detection.
- When the shackles and pins are obviously deformed.
- When there are cracks and fissures visible to the naked eye.
Usage Guidelines
- Inspect the shackle for damage or wear before each use.
- Avoid exceeding the WLL.
- Ensure proper alignment and avoid side loading.
- Tighten the pin securely, but do not overtighten.
- Replace the shackle if there are signs of deformation, corrosion, or cracks.
