Connecting link is an indispensable key component in lifting and hoisting system. As the core connection between the hook, the spreader and the suspended object, it bears the important functions of transferring load, dispersing stress and ensuring safety. Whether in construction sites, port terminals, heavy machinery manufacturing or energy engineering fields, lifting connection rods are the core guarantee for safe and efficient lifting operations with their high strength, high reliability and adaptability.
Excellent load-bearing performance
The connecting link is made of high-strength alloy steel.Its tensile strength and yield strength exceed the industry standards, and can withstand the ultimate load of several tons to hundreds of tons.
Precision heat treatment processes (such as tempering and quenching) ensure that the internal structure of the material is uniform, improve fatigue resistance, and extend the service life.
Scientific and safety of structural design
The key connection parts are strengthened and equipped with anti-trip devices and safety pins to prevent accidental release.
The surface galvanized can provide excellent corrosion resistance and can adapt to harsh environments such as humidity and high temperature.
Modular and standardized design
Providing a variety of specifications of connecting link to meet the lifting needs of different tonnage and span.It supports quick adaptation with hooks, shackles, pulley sets and other accessories, and is compatible with international standards, reducing maintenance costs.
