Port loading and unloading machinery is the main body of the normal throughput of the port lifting loading and unloading, mainly using wire rope for port machinery, from the perspective of wire rope use, the main varieties of port loading and unloading machinery are: quayside container cranes, tire container cranes, portal cranes and multi-purpose portal cranes.

The working characteristics of the wire rope for port loading and unloading machinery: the main characteristics of the complex force state of the lifting wire rope port loading and unloading machinery are rapid lifting and landing, and accompanied by a large impact load. The wire rope for port machinery is usually in the state of a large inclination angle in the vertical direction of the loading and unloading ship, and the hook of the port machine is accompanied by the rapid synthesis of vertical and horizontal motion at the same time, sometimes the synthesis motion is carried out in three-dimensional space. The force state of hoisting wire rope is complex. The use of harsh conditions, harsh working environment, port handling wire rope in the open air and accompanied by a larger corrosive atmosphere of humidity or dust larger environment work. The steel wire rope is required to have great structural advantages, good physical quality level and performance. It is required that the lubricating oil of the steel wire rope dip coating has excellent performance, strong adhesion, and can be in good condition for a long time. If it is insufficient, it should be supplemented in time. The rope wheel of port handling machinery is usually small, and the wire rope is required to have high bending fatigue resistance. Multi-strand and multi-filament plastic-filled steel wire rope shows great advantages in structure and performance.

Yun Yu wire rope mainly produces various kinds of wire rope for port machinery, drilling wire rope, shaft wire rope, rotary digging machine wire rope, crane wire rope, elevator wire rope, other special wire rope and other wire rope.
