Electro-Permanent Lifting Magnets
Electro-Permanent Lifting Magnets
Electro-permanent lifting magnets offer a dependable solution for lifting ferrous materials while combining the consistency of permanent magnets with the controllability of electric-powered activation. Unlike standard electromagnets, these tools require power only during activation and deactivation—not while holding the load. This means you get a strong grip with less energy use, increased efficiency, and safer operation in case of power loss.
At Holloway Houston, we provide a selection of electro-permanent lifters designed for use in metalworking shops, warehouses, and handling stations that need frequent steel movement. They are especially useful in environments where keeping a constant power supply can be challenging or where safety is a top concern.
What Makes Electro-Permanent Magnets Unique?
These lifters use a short electrical pulse to switch the magnet on or off, but the lifting force is maintained by a permanent magnetic field. Because the magnet stays active without needing continuous power, it reduces electrical consumption and improves safety—especially when lifting over people or sensitive areas. If the power cuts off unexpectedly, the load remains held until it is safely released with another pulse.
This function makes electro-permanent lifters a great fit for both production lines and outdoor lifting scenarios, where power interruptions are more likely. They offer precision control and reduced heat generation, allowing for repeated lifts without risk of overheating.
Available Sizes and Capacities
Our electro-permanent lifting magnets are available in a range of sizes to meet different steel lifting needs. Capacities typically range from 550 lbs to over 2,650 lbs, depending on the model and steel surface contact. These units are compact, making them easy to install on cranes, jib arms, or gantries.
Some models are designed for flat surfaces, while others can grip round stock such as pipes or bar materials. Sizes vary, but most units are manageable and light enough for use in multi-point lifting setups with spreader beams or custom frames.
For projects that require more flexibility, you may also consider pairing electro-permanent units with lifting points or modular spreader bars to stabilize longer loads.
Applications Across Industries
Electro-permanent lifters are used across several sectors where regular lifting of steel materials is part of the daily routine. Common applications include:
- Loading/unloading steel sheets in cutting shops
- Lifting steel rounds and plates in machine shops
- Transferring materials in fabrication bays
- Handling parts in automated lifting stations
- Removing flame-cut parts or structural sections from beds
Their ability to maintain hold without power makes them especially helpful in situations where lifts are paused mid-operation or when safety must be maximized during movement.
Why Choose Electro-Permanent Over Electromagnetic?
While both lifters serve similar purposes, electro-permanent models bring added benefits:
- Power is only used during switching
- No heat buildup from long holds
- Grip remains in case of power failure
- Lower energy costs over time
- Simplified controls with no continuous current draw
For users already working with electromagnetic lifters, these models may offer a more efficient upgrade, especially for static lift setups or repeated lifting stations.
Safety and Usage Tips
Even though these lifters hold without ongoing power, using them correctly is important for safe lifting. Always check that the load surface is clean and flat, as surface debris or paint may reduce the magnetic contact. Also, make sure the load is within the rated capacity and avoid lifting over people or with sharp load edges.
Before each shift, inspect the lifter’s surface and controls. When not in use, store the magnet in a designated area away from loose hardware or filings that may get attracted to the surface.
For taller plates or off-center lifting, consider using two or more magnets in combination to keep the load balanced and reduce bending.
