• Mag-Mate Basic Lift (BL Series): Economical and effective lifters with capacities from 400 lbs to 1,500 lbs.
• Mag-Mate Advantage Lift (AL Series): High-performance rare earth magnets with WLL up to 2,200 lbs.
• Mag-Mate Creative Lift (CL Series): Durable ceramic magnets designed for heavy steel, with capacities up to 3,000 lbs.

Electromagnetic Lifters (Powered Control)

Electromagnetic lifters require an external power source (AC or DC) to generate a powerful magnetic field. Their primary advantage is controlled magnetization, allowing operators to activate or deactivate the magnetic field on command using a controller.

This feature is important in applications where precise control over the lifting and releasing process is necessary, such as automated production lines or scrap handling operations.

Our Electromagnetic Products Include:

• Walker Magnetics CER Series: A range of heavy-duty round electromagnetic lifters, with models from 5" (600 lbs) to 20" (10,500 lbs) designed for industrial applications.

Electro-Permanent Lifting Magnets (Hybrid Safety & Efficiency)

Electro-permanent lifting magnets (EPMs) combine the safety of permanent magnets with the control of electromagnets. They use a brief electric pulse only to switch the magnetic field on or off.

Once activated, the magnet holds the load securely like a permanent magnet, with no continuous power required. This fail-safe design means that a power failure will not result in the load being dropped. This design is also highly energy-efficient and generates no heat, preserving the magnet's lifting force.

Our EPM Products Include:

• Mag-Mate FXE Series: Designed for a variety of applications, including narrow or long-profile items.

Holloway Houston electro-permanent magnets combine permanent magnet safety with electromagnetic control. Power is only needed during MAG/DEMAG cycles, while holding requires no electricity. These magnets provide precise single sheet picking and remote operation. They are ideal for automated production lines, long beam handling, and areas without power access. EPM models maintain a 3:1 safety factor per ASME B30.20 and provide energy savings of up to 95% compared to traditional electromagnets.

Battery-Operated Lifting Magnets

For portability and powered control, battery-operated lifting magnets provide a self-contained solution. These lifters use an onboard rechargeable battery to power the magnet, eliminating the need for a tethered power cord.

This makes them ideal for use on mobile gantry cranes, forklifts, or in large yards where a power supply is not easily accessible. They offer the same "push-button" control as standard electromagnetic lifters but with complete freedom of movement.

Our Battery-Powered Products Include:

• Walker Magnetics BUX Series: Heavy-duty battery lift electromagnets for flat material, with capacities from 3,000 lbs to 11,000 lbs.

How to Select the Right Lifting Magnet

Selecting the correct lifting magnet is important for safety and efficiency. Using the wrong magnet can result in reduced lift capacity or a failed lift. Always consider the following factors:

• Material Type and Thickness

  The magnet's rated capacity is based on lifting clean, flat, low-carbon steel (like ASTM A36). Alloy steels, cast iron, and other materials have reduced magnetic permeability and will lower the magnet's capacity. Material thickness is also important; thin materials (under 1/2") may not be thick enough to absorb the full magnetic field, reducing the WLL.

• Weight Capacity (WLL)

  Select a magnet with a Working Load Limit (WLL) that is appropriate for your maximum intended load. Never exceed the rated capacity. Remember that the WLL is often de-rated for round materials or non-ideal surfaces.

• Surface Condition and Air Gaps

  The rated capacity assumes perfect, flat, clean surface-to-surface contact. Any "air gap" between the magnet and the load will dramatically reduce lifting power. Air gaps can be caused by:

  • Rust, scale, or paint
  • A rough or uneven material surface
  • Dirt, debris, or paper
  • Non-flat or warped plates
• Operating Environment

  Consider environmental factors. Standard lifting magnets have a maximum operating temperature (e.g., 180°F). Using them on hotter materials can permanently damage the magnet and cause it to fail.

• Power Availability

  Your worksite dictates the magnet type. Do you have an available power source on your crane? An electromagnetic lifter may be suitable. Are you in a remote yard or using a forklift? A permanent or battery-operated magnet is the correct choice.

Lifting Magnet Safety, Inspection & Troubleshooting

Make sure the operational safety and compliance is vital in all material handling operations. Regular inspection and maintenance of lifting magnets are important for safe, reliable performance and to validate full compliance with ASME B30.20 standards. Our magnets are designed to meet these stringent requirements, including OSHA 1910.184, when properly selected, inspected, and operated.

ASME B30.20 Inspection Requirements for Industrial Lifting Magnets

All lifting magnets must undergo regular inspections as outlined by ASME standards.

Initial Inspection (Before First Use) Before any lifting magnet is placed into service, an initial inspection must be performed. This important first step verifies that the equipment meets all safety specifications and includes:

• Verifying all identification markings are present as required by ASME.
• Checking for documented proof testing, which certifies the magnet to 125% of its rated capacity of working load limit (WLL).
• Confirming the 3:1 safety factor certification.
• Testing the ON/OFF mechanism to ensure correct and secure operation.

Frequent Inspection Schedule Regular inspections must be performed by a qualified individual. The frequency of these inspections is determined by the magnet's service class:

• Normal Service: Monthly
• Heavy Service: Weekly
• Severe Service: Daily

Key Inspection Points During each inspection, the following points must be thoroughly examined:

• Magnetic Face: Check for any cracks, excessive wear, or contamination that could compromise contact.
• Handle/Mechanism: Handle lock mechanism functions correctly and engages fully.
• Housing: Inspect the magnet body for any signs of damage, cracks, or distortion.
• Lifting Lug/Shackle: Examine the lifting point for wear, elongation, or other damage.
• Labels: Verify that all warning labels are present and fully legible.

Common Lifting Magnet Issues & Solutions

Even with proper maintenance, operators may encounter issues. Understanding the common causes and solutions is key to maintaining safety and productivity.

Reduced Lifting Capacity

• Cause: The presence of "air gaps" created by rust, paint, or other contamination on the load surface.
• Solution: Thoroughly clean the magnet's contact surface. It is also critical to verify that the material's thickness meets the minimum requirements for the magnet's rated capacity.

Multiple Sheet Pickup

• Cause: The magnetic field "bleeds through" thin materials, causing the magnet to unintentionally lift multiple sheets at once.
• Solution: Use a specific thin-sheet-handling magnet model. For advanced applications, an Electro-Permanent Magnet (EPM) with adjustable force can be set for single sheet picking.

Load Won't Release

• Cause: Residual magnetism remains in the material after the magnet has been switched off.
• Solution: Ensure the ON/OFF lever is moved to the complete OFF cycle. Also, check for a proper magnet-to-load ratio, as this can sometimes occur if the magnet is not correctly matched to the load.

Technical Specifications

Lifting Capacity by Material Type

Magnet performance changes depending on the type of material being lifted. Some metals, like low carbon steel, allow full lifting strength, while others, such as cast iron or stainless steel, reduce the magnet’s holding power. The table below shows the approximate lifting capacity for different materials.

Magnet Type Comparison

Each magnet type works differently based on how it’s powered and controlled. Permanent magnets need no electricity, while electromagnets use continuous power. Electro-permanent and battery-powered models provide more control and flexibility. The table below shows the main differences between them.

Frequently Asked Questions About Lifting Magnets

Question 1

Q: What is the safety factor for Industrial Magnetics lifting magnets?
A: All our lifting magnets maintain a 3:1 safety factor per ASME B30.20. This means the breakaway force is three times the stated Working Load Limit (WLL), providing substantial safety margin.

Question 2

Q: Do lifting magnets require electrical power?
A: No. Permanent lifting magnets use rare earth or ceramic magnetic material to generate holding force without electricity. A mechanical ON/OFF lever controls the magnetic field.

Question 3

Q: What thickness steel can lifting magnets handle?
A: Lifting capacity varies by material thickness. Thin sheets under 1/4" have reduced capacity, while steel 2" and thicker achieves full rated capacity. Consult capacity charts for specific models.

Question 4

Q: Are lifting magnets OSHA compliant?
A: Yes. When properly selected, inspected, and operated as per manufacturer guidelines, our ASME B30.20 certified magnets meet OSHA 1910.184 requirements for below-the-hook lifting devices.

Question 5

Q: Can lifting magnets pick up hot steel?
A: Our magnets operate safely up to 180°F (82°C). For higher temperature applications, specialized high-temperature models are available.

Question 6

Q: What's the difference between permanent and electro-permanent lifting magnets?
