Shipyard and port

In the wave of Industry 4.0, electro-permanent magnet technology is revolutionizing heavy lifting, injecting strong momentum into shipbuilding and smart port construction. With its core advantages of "millisecond response adsorption" and "millimeter-level precision control," this technology has deeply empowered leading shipbuilders such as Hudong-Zhonghua and Jiangnan Shipyard, achieving high-frequency, precise lifting and intelligent sorting of large steel plates. It creates a new handling mode with low energy consumption, high safety, and full automation, driving the green transformation of the port and shipping industry. At Liangshan Port's smart terminal, the magnetic control system successfully managed the unmanned stacking of steel coils exceeding 35 tons, setting an industry record with millimeter-level positioning accuracy. From dockyards to coastlines, this magnetic technology, as a testament to Chinese manufacturing, is outlining a magnificent picture of intelligent industry against the backdrop of the sea and sky. It provides a Chinese solution for the intelligent upgrading of global port and shipping equipment, writing a brilliant chapter in the industrial revolution of the new era.

Unable to ensure personal safety
High labor cost input and low efficiency

Traditional hoisting equipment is backward

Vacuum suction cups have poor adaptability
Grippers and clamps easily damage workpieces

High energy consumption

Electro-permanent magnets are 95% more energy-efficient than electromagnets
Taking a steel plant as an example, it can save 200,000 yuan a year (taking Liugang as an example)

Some applications of electro-permanent magnets in the industry

Steel plant

In steel plants, Qianhao electro-permanent magnets have significant advantages in the handling of finished steel products. When hoisting steel plates, steel pipes, steel coils and profiles, it can quickly adsorb and firmly fix, adapting to different specifications and shapes. The palletizing operation is neat and efficient, greatly shortening the loading and unloading time, reducing labor intensity, reducing steel collision damage, and effectively improving the production efficiency and economic benefits of steel plants.

Steel trade logistics park

In steel trade logistics parks, Qianhao electro-permanent magnets are very useful. In the loading and unloading process of finished steel plates, steel pipes, steel coils and profiles, it can respond quickly, generate strong magnetic force in an instant when energized, firmly adsorb goods, and the magnetic force still exists after power failure, ensuring safe and efficient loading and unloading. It is easy to operate and can flexibly adapt to steel materials of different specifications and shapes, reducing labor intensity and loading and unloading time, and improving the overall operation efficiency of the logistics park.

Engineering machinery manufacturing

In engineering machinery manufacturing, Qianhao electro-permanent magnets perform brilliantly. Taking laser feeding and unloading as an example, its strong magnetic force and precise adsorption can completely and steadily unload more than 300 parts from the processing area at one time. This feature greatly improves production efficiency, effectively reduces manual operation time and errors, ensures smooth and efficient production process, and provides strong support for engineering machinery manufacturing enterprises to achieve cost reduction and efficiency improvement.

Steel structure processing

In steel structure processing, Qianhao electro-permanent magnets are widely used. In the cutting process, it can quickly fix the steel plate to prevent displacement; during welding, it can accurately position the components to ensure welding accuracy; in the assembly stage, it helps to hoist and connect large steel components, improving processing efficiency and quality.
