In laser cutting production, the efficiency and precision of the material preparation stage directly affect overall production capacity and sheet utilization. Traditional lifting methods often suffer from issues such as sheet deformation, difficult positioning, numerous safety hazards, and poor integration with automation—especially when handling thin sheets, large-format sheets, or workpieces that have already been cut and separated. The conventional magnetic approach... Lifting gear Problems such as unstable adsorption and swinging during lifting are becoming more prominent.
In response to the above challenges, Full-coverage electro-permanent lifting magnet Thanks to its advantages—such as uniform magnetic distribution, retention of magnetism even after power failure, rapid response, energy efficiency, and safety—it has gradually become the preferred equipment for the material preparation stage in laser cutting. It is not only suitable for conventional steel plates but can also handle complex conditions involving perforated materials, cut seams, and irregular-shaped scraps, enabling efficient, smooth, and automated lifting operations.
QHMAG Full-coverage electro-permanent lifting magnet The core advantage
QHMAG Electro-permanent lifting magnet It features a full-surface magnetic circuit design with uniform magnetic coverage, effectively preventing plate deformation caused by localized stress. Equipped with patented electronically controlled permanent magnet technology, it enables rapid magnetization and demagnetization; once power is cut off, the magnetic force remains intact, making it particularly well-suited for frequent lifting operations and integration into automated production lines. In addition, this... Lifting gear Supports multiple lifting methods (single hook/dual hooks/Gantry crane combination), offering strong adaptability and high safety.
II. Essential Selection Parameters: Clearly Define Requirements, Achieve Precise Matching
To ensure Lifting gear Fully matches the on-site operating conditions. Before selecting a model, be sure to confirm the following information:
✅ Operating condition parameters
Steel plate dimensions: range of length, width, and thickness
Cutting piece dimensions: maximum and minimum workpiece length and width
Material properties: Whether magnetic (electropermanent magnets are applicable only to ferromagnetic materials such as steel).
✅ Equipment requirements
Crane rated load
Lifting method: Single hook / Double hook / Girder type Lifting gear
Power Supply Type and Interface Method
Providing clear information can help the technical team recommend the most suitable magnetic pole configuration for you. Lifting gear Structural and control systems to achieve efficient, stable, and safe lifting operations.
