Application No.: CN202422614693.5

Public Account ID: CN223213633U

Hunan Qianhao Magnetic Electric Technology Co., Ltd. As one of the leading enterprises in the field of electro-permanent magnet technology, leveraging its outstanding R&D capabilities and a relentless spirit of innovation, it recently succeeded in obtaining a patent granted by the National Intellectual Property Administration. Utility Model Patent Certificate (Patent No.: CN223213633U) The approval of this patent once again marks a significant technological breakthrough for Qianhao Magnetic Electric in the field of intelligent lifting equipment, further solidifying its vision to strengthen its leadership position in the electro-permanent magnet industry.

Innovative Technology Highlight: Redefining Lifting Safety and Efficiency

The patent-eligible one this time Automatic Suction and Release Electromagnetic Permanent Magnet Through the deep integration of structural optimization and intelligent control systems, a revolutionary upgrade in the field of material handling has been achieved:

Release for automatic material suction, lift to hoist and transport, then lower again for automatic unloading.

Integrated Intelligent Design
The equipment integrates an electro-permanent magnet, a triggering mechanism, a manual control panel, and lifting connection components. An electrical control unit is built into the top containment chamber, enabling the sequence of "magnetic force generation—state detection—magnetic control adjustment." Full-process automation The hook structure is linked with the triggering mechanism, allowing precise magnetic switching via external operation.

Dual Magnetic Control Mode

The electrical control unit continuously monitors the magnetic pole status in real time, rapidly outputs the magnetizing current based on the trigger signal, and seamlessly switches between the "strong-suction lifting" and "zero-residual-magnetism release" modes, ensuring a safe material-handling process free from residual magnetic interference.

High * Maintenance and Adaptability

Optimizing the bottom magnetic pole layout enhances suction uniformity, while the modular design significantly reduces maintenance complexity. This system can be widely applied in scenarios such as steel processing, machinery manufacturing, and warehousing & logistics, meeting the demands of high-precision and high-frequency operations. It is suitable not only for lifting steel plates and billets but also for handling special-shaped components like round bars and profiles.

 Compared to traditional permanent magnet lifters, electrically powered permanent magnets—especially those emphasizing automation—are better suited to meet the demands of lifting operations that involve handling multiple steel plates, stacking them individually, or working with plates of varying sizes. 

Driving industry upgrades through technology

Qianhao Magnetic & Electric has consistently upheld the corporate philosophy of "Innovation as the foundation, quality as the soul," and has been deeply rooted in the field of electro-permanent magnet technology for over two decades. The recent acquisition of this patent not only recognizes the team's outstanding R&D capabilities but also underscores the company's forward-thinking insight into market demands—particularly in the context of Industry 4.0, where intelligent, unmanned operations have become the prevailing trend. Indeed, automated lifting and releasing technology serves as the crucial link bridging traditional lifting equipment with the factories of tomorrow.

The company's Chief Technology Officer stated “This patent addresses the issues of high energy consumption and magnetic control hysteresis commonly found in traditional electromagnets. At the same time, by integrating mechanical triggering with an advanced electro-control system, it significantly enhances operational safety. Moving forward, we will continue to drive the convergence of electropneumatic magnet technology with IoT and AI, creating greater value for our customers.”
