Magnetic Lifter 300kg: Practical Questions About the PML Type

The PML series is intended for thin workpieces made from ferromagnetic materials, including steel plates and similar steel-handling applications. Its deepened U-shaped groove increases the range of workpiece shapes it can accommodate, while the dual magnetic circuit provides a broad adsorption range.

Picture a warehouse moving thin steel plates from storage for loading. The buyer should match the plate material and shape to the lifter's contact area, then select a rated load that covers the intended workpiece. For a 300kg load requirement, the 300kg PML option is the relevant configuration to discuss with the supplier.

No. The PML uses non-electric operation, so it does not require an external power source or electrical cable. This suits handling areas where a manual lifting tool is preferred and where the work path does not include a convenient power supply.

The PML series is available with rated loads of 300kg, 600kg, 1000kg and 2000kg. Choose the capacity according to the load being lifted, and keep every lift within the selected unit's rated load range. The 300kg model is the appropriate option for loads up to its rated range when the workpiece also meets the material and operating requirements.

The lifter must be used within its rated load range, and overloading is prohibited. The product must not be run without a load, and no one may stand or walk beneath it during work. The operating temperature must not exceed 80°C to avoid demagnetization.

The PML has a safety factor of up to three times. That figure does not change the selected unit's rated load: a 300kg model must still be used within its 300kg rated load range. Workpiece length must not exceed 3 meters for one unit. For a longer workpiece, the product guidance recommends using two or more units.

A practical preparation check is to confirm the workpiece length, material and temperature before lifting. In a loading area, keep people out of the space below the suspended plate and plan the lift so the unit remains within its rated range.

The PML product guidance requires a load test every two years from the date of use. Buyers should include this two-year testing interval in their equipment inspection planning.

The product is packed in fumigation-free wooden cases with crash-resistant foam board inside and a reinforced steel fastening belt outside. Supported transportation modes are sea, air express and rail. The recommended mode depends on the order quantity.

Yes. OEM and other customized services are supported. A buyer requesting customization should send the intended rated load, workpiece material and shape, maximum workpiece length, operating temperature and order quantity so the supplier can review the configuration and transport arrangement.
