Permanent Magnetic Lifter (PML-A Type)

Industrial Solution for Plate & Round Steel Material Handling
Zero Electricity Required Neodymium Magnets Safety Factor 3:1 V-Slot Base

The PML-A series utilizes high-energy Neodymium (NdFeB) magnetic materials to deliver immense lifting power in a compact design. Requiring no electrical power, these lifters completely eliminate the risk of load drops due to power failures. Designed for versatility, they are ideal for lifting, moving, and positioning steel plates, blocks, and cylindrical materials.

⚠️ Critical Safety & Operational Guidelines

  • Surface Contact: Lifting capacity is strictly dependent on the thickness, surface roughness, and material composition of the steel. Rust, scale, or air gaps will drastically reduce magnetic pull.
  • Derating for Round Steel: The rated capacity for lifting round steel (pipes/shafts) is inherently lower than for flat plates. Always reference the capacity chart before lifting.
  • Manual Safety Lock: Always ensure the handle is fully engaged and the safety lock button is secure before lifting to prevent accidental de-magnetization.
  • Never lift loads over personnel and do not exceed the maximum rated capacity.

Key Features & Benefits

Universal V-Slot Application: Designed with a specialized V-slot machined into the lifting face, allowing the lifter to securely grip both flat steel plates and round steel components (such as pipes and solid shafts).

Compact & Durable: Features a rugged, painted steel housing with a heavy-duty chrome-plated shackle, providing high impact resistance for harsh factory environments.
Zero Electricity Needed: The mechanical lever simply shifts the internal magnetic field to engage or disengage the load, meaning zero running costs and no trailing cables.
Global Standards: Fully compliant with international lifting standards including EN 13155, AS 4991, and ASME B30.20.

Principles for Selection

Magnetic lifters are versatile tools for handling steel plates, blocks, and rounds. They can be used as general-purpose accessories or dedicated to specific applications. However, proper selection is critical for safety.

⚠️ CRITICAL SAFETY NOTE:
Not every load with ferromagnetic properties can be safely handled. The lifting capacity is significantly affected by the thickness, surface finish (air gap), and chemical composition of the load.

Matching the Magnet to the Load

Shape Compatibility

The shape of the magnet face must match the load:

  • Flat Material: Requires a magnet with a flat face for maximum contact area.
  • Round Material: Requires a magnet with a V-shaped recess to properly center and grip the cylinder.

Long & Flexible Loads

For long or flexible plates that may peel off a single magnet, use an arrangement of several magnets in conjunction with a spreader beam. Ensure the magnets are spaced to provide adequate support along the entire length to prevent sagging.

Load Orientation

Lifting magnets are normally rated for lifting a horizontal load in the vertical plane only. If the line of pull is not perpendicular (at right angles) to the load surface, the lifting capacity is substantially reduced, and slippage may occur.

Key Selection Considerations

When selecting a magnetic lifter, evaluate the following 11 points:

  • 1. Capacity: Required Working Load Limit (WLL).
  • 2. Load Characteristics: Shape, surface finish (air gap), and steel grade.
  • 3. Operation Type: Frequency and nature of the lift.
  • 4. Compatibility: Type of hoist/crane the magnet is attached to.
  • 5. Headroom: Available vertical space for the lifter.
  • 6. Portability: Self-weight of the magnet.
  • 7. Controls: Manual lever handle vs. automatic cycling.
  • 8. Power: (If using electro-permanent) Electrical requirements.
  • 9. Personnel: Proximity of people during operation (Safety zones).
  • 10. Redundancy: Need for backup safety features (e.g., dual lock handle).
  • 11. Compliance: Required documentation and certification.
