Permanent lifting magnets are common in mechanical equipment factories. Workers use them to move heavy steel plates. However, these magnets often create significant problems. Understanding these issues helps companies improve safety and efficiency.
Permanent Lifting Magnets Disadvantage
Firstly, permanent lifting magnets lack adjustability, Factories handle plates of varying thicknesses. For instance, plates might range from thin 5mm sheets to thick 40mm slabs. Permanent magnets exert the same strong force on all thicknesses. Consequently, thin plates frequently stick together. Workers then struggle to lift just one sheet, which causes delays and frustration. Moreover, separating stuck plates wastes valuable production time.
Secondly, these magnets are often bulky and heavy. Large equipment needs big, powerful magnets. Therefore, the magnets themselves become massive. This creates handling difficulties. Workers find them awkward to position, furthermore, their size causes interference near other machinery. Space is often limited on busy factory floors. Ultimately, bulky magnets pose serious safety hazards,accidental drops become more likely.
Thirdly, reliability issues frequently occur. Permanent magnets depend solely on their fixed magnetic field,no power adjustment exists. Over time, their strength might weaken slightly, unexpected failures can happen. Workers will face risks daily. Also, synchronizing multiple magnets is tricky. If magnets don’t engage perfectly together, plates can slip dangerously. This inconsistency disrupts workflow.
Electro Permanent Magnetic Solution
So, what solutions exist?  Adjustable electro permanent magnetic systems solve these core problems. Look at a real example. One environmental equipment maker switched from permanent lifting magnets. They needed to lift diverse steel plates (3-12m long, 1-3.5m wide, 5-40mm thick). Their old permanent magnets caused plate sticking and safety concerns. Furthermore, the magnets were simply too cumbersome.
The company adopted a modular electromagnetic lifting system. Specifically, they used HVR MAG HM2 magnetic lifter with telescopic beam, which allowed adjustable magnetic force. Workers could easily tailor the power for different plate thicknesses. As a result, single-sheet lifting became reliable for all sizes. Crucially, the new system was compact – only 6.3 meters long, eliminated space conflicts. Moreover, the electropermanent magnetic design boosted reliability. Synchronization problems vanished, ensuring safer, smoother operations.
Conclusion
The modern, adjustable electropermanent magnetic lifting tools offer a smarter path forward. Enhancing safety, efficiency, and flexibility in demanding production environments.
