It has a small volume but high strength. Shackles are generally used for lifting and hoisting, and mastering the correct method of using them is necessary to ensure operational safety.
The maximum working load and scope of use of the shackle are the basis for testing, inspection, and use of the shackle, and overloading is strictly prohibited.
The shackle body is forged from high-quality carbon steel or alloy steel and subjected to heat treatment.
The experimental load of the shackle is twice the ultimate working load, and the breaking load is four times the ultimate working load.
