Shackles include general lifting shackles, marine shackles and ordinary shackles. The weight is heavy and the volume is large. Generally, it is not installed in the position where it is not often disassembled.

Excessive frequent use and overload use are not allowed. Shackles are widely used in electric power, metallurgy, petroleum, machinery, railway, chemical industry, port, mining, construction and other industries.1. Small size, 2. Large bearing weight, 3.
