Intelligent lifting tools for steel plants

Steel plate lifting

Taking Liugang as an example, Qianhao's electro-permanent magnetic lifter can lift 8 steel plates and accurately place one, requiring only one person to operate the remote control, ensuring personnel safety.

Intelligent lifting tools for steel plants

Silicon steel lifting

Taking Wuhan Iron and Steel as an example, facing the uneven surface of vertically placed silicon steel, Qianhao's experiment can lift 20 tons of vertically placed silicon steel with 2mm thick wooden boards.

Lifting

Steel pipe lifting

Taking Tianjin Steel Pipe as an example, in order to solve the high-efficiency requirements of loading, unloading, and stacking, Qianhao magnetic electricity designed an electro-permanent magnetic lifter that can not only lift bundles of steel pipes but also rows of steel pipes.

Production lines of engineering machinery manufacturing enterprises

Manufacturing of various engineering machinery equipment

In the production lines of cranes, road rollers, excavators, bulldozers, etc., from the warehousing and lifting of steel plates to the loading and unloading of laser cutting, to sorting and stacking, and welding, Qianhao magnetic electricity has mature and配套的 electro-permanent magnetic iron equipment to solve them one by one.

Industry application fields

Steel material logistics park

Such as Hunan Yili Logistics, thanks to the precise adsorption and stacking of electro-permanent magnets, the entire logistics park uses electro-permanent magnetic equipment for the handling and sorting of steel materials. Its efficient and precise adsorption capacity reduces manual handling errors, improves logistics efficiency, and enhances personnel safety.

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.

Industry pain points

Low efficiency of manual hoisting

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.
