Screw ship unloader manufacturers take you to understand the working characteristics of stainless steel wire rope for ship unloader

(1) The stress state of lifting stainless steel wire rope is complex, which is characterized by rapid lifting and landing, accompanied by large impact load.

The stainless steel wire rope usually works in the state of large inclination angle with the vertical direction of the loading and unloading ship. The grab bucket of the ship unloader carries out the rapid synthetic movement of the vertical, horizontal, front and back space with the cargo at the same time, and sometimes the synthetic movement is carried out in the three-dimensional space. The stress state of lifting stainless steel wire rope is complex.

(2) Most of the steel wire ropes used for loading and unloading in port work in the open air with high humidity or dust, and with a large corrosive atmosphere. It is required that the steel wire rope should have great structural advantages, good physical quality level and service performance.

(3) The winding system of stainless steel wire rope is more complex. In order to coordinate rhythmic, short cycle and frequent operation, a working cycle is usually less than one minute. According to the design procedure, the process of catching, transporting and unloading bulk cargo is completed, which makes the winding system of wire rope naturally more complex.

The positive and negative directions of the wire rope change a lot, thus greatly shortening the service life.

(4) The lubricating oil for stainless steel wire rope is required to have excellent performance, strong adhesion, and be in good condition for a long time. If it is insufficient, it should be supplemented in time.

Stainless steel wire rope should not only be in good lubrication state, but also effectively block the fine particles of coal powder and mineral powder flying around, so as to prevent these harmful substances from entering between strands of wire rope and between wires, which will cause extra wear and damage during the working period of wire rope.

(5) The rope pulley of port handling machinery is usually small, especially the stainless steel wire rope is required to have high bending fatigue resistance.

(6) The stainless steel wire rope has the phenomenon of extended service.
