The wire rope as traction, carrying the key components widely used in various fields of national economic construction of the coal, metallurgy, high-rise buildings to enhance transportation, ports, tourism plays an important role. Lifting in the port area, the wire rope in the course of their work, due to the load uncertainty inevitably produce a variety of injuries, resulting in lower actual affordability of the wire rope tension wire breakage caused by the plane crash, economy losses, a huge social impact.
Therefore, the port users and researchers hope that the use of scientific methods and technical means to monitor the dynamic usage characteristics of the wire rope, in order to ensure the safe use of wire rope and reasonable update. The traditional strong magnetic Wire Rope Inspection Technology in principle and field characteristics, its feasibility and stability are bottlenecks. Wire rope inspection technique, based on the independent launch electromagnetic variable compensation feedback technology to achieve the quantitative detection of wire rope fatigue damage and quantitative assessment of the carrying capacity of the wire rope, and solve the problem of the port wire rope carrying, engineering and the port area network type three options to fill the field of international blank.

Currently, the port industry is basically using artificial methods to detect and manage wire rope, manual inspection can only be found wire rope obvious external damage, internal damage can not be found. More importantly, statistics show that more than 80 percent of the broken wire damage caused by fatigue, fatigue damage can not be found by manual inspection. Developed based on manual inspection, visual inspection of the wire rope safety regulations and testing specifications, all belong to the type of experience to judge, the low level of science. With the advances in technology of wire rope inspection, safety and economic issues of the wire rope to the period of use of science and technology and scientific means to resolve it.

Wire Rope NDT technology, the world's leading port hoisting machinery special customization and development "rope-line testing system" will be an effective solution to carrying wire rope safe use and management challenges. The system will be the line automatic inspection of the     Welding Wire rope to the implementation of all-round, all-weather, quantitative detection of external broken Mig Welding Wires in the wire rope, wear, corrosion, and fatigue caused by a variety of injuries the actual load capacity degradation degree of new technical means, to achieve security, savings, efficient "triple-management goals. The company's technical staff has complete technical validation and communication ports such as Shanghai, Shenzhen, Guangzhou, Ningbo, and lay a good foundation for the next step of the world's first port hoisting machinery "Made in China" online testing system.
