Modern lifting magnets are categorized into three main types:
Permanent Magnets: These require no external power and are ideal for environments where electricity is unavailable. They are tested at a safety factor of 3:1 or higher, meaning a magnet rated for 2,200 lbs is tested to hold 6,600 lbs under ideal conditions. Heavy Duty Strong Pickup Magnetic Lifting with Quick Release
Battery-Powered/Cordless Electric: These units, such as the Magswitch CE series, offer the convenience of permanent magnets with the added benefit of remote “on/off” switching, with capacities reaching up to 11,000 lbs or more.
Electro-Permanent Magnets: These use an electric pulse to switch the state of a permanent magnet, combining the safety of permanent magnets (they won’t drop the load if power fails) with the automation capabilities of electromagnets.
When selecting a magnet, operators must account for the “Air Gap” (rust, paint, or scale), which significantly degrades lifting capacity. For example, a small air gap of just 0.5 mm can reduce lifting power by over 50%. Most industrial units conform to standards such as ASME B30.20, ensuring they meet rigorous safety and design criteria for below-the-hook lifting devices.
A steel plate lifting magnet is a specialized material handling tool that utilizes magnetic flux to secure and transport ferromagnetic loads, such as steel plates, blocks, and cylinders, without the need for slings or chains. These devices primarily function through either permanent magnets, which use high-grade Rare Earth materials like Neodymium to maintain holding power indefinitely without electricity, or electromagnets and cordless electric designs that allow for remote operation and higher capacity handling. Permanent models, such as the Max Lifter series, are activated via a manual lever that aligns the internal magnetic poles to “turn on” the flux; they often include safety features like a spring-loaded locking block to prevent accidental deactivation during a lift.
