Showing the single result

Permanent magnetic lifters offer a safe, efficient, and power-free method to lift ferrous materials. Designed for industrial use, they ensure precision handling with minimal effort and zero energy consumption.

What is a Permanent Magnetic Lifters

A permanent magnetic lifters is a mechanical tool used to lift and handle heavy ferrous materials such as steel plates, blocks, and round bars. It uses a powerful magnetic field generated by rare earth magnets, especially NdFeB (neodymium-iron-boron), to create a strong grip on metal surfaces.

These lifters do not require electricity or batteries. Instead, a manual lever controls the magnetic field, making it safe, cost-effective, and ideal for various industrial applications. Permanent magnetic lifters are compact and simple to use. They help improve handling speed and reduce reliance on slings, hooks, or chains.

Why Choose a Permanent Magnetic Lifters

Permanent magnetic lifters provide several practical advantages for industries that handle steel and iron materials:

  • No Power Required: These lifters work without electricity, reducing the risk of failure due to power loss. 
  • Low Operating Cost: With no motors, wiring, or power components, there is no maintenance cost.
  • Quick Operation: One operator can lift and move heavy loads with ease. 
  • Safety Factor: High-quality models offer a 3:1 safety ratio, meeting international safety standards. 
  • No Damage to Workpiece: Lifting leaves no marks or dents on the surface of the material.

Their compact design and ease of use make them a long-term lifting solution across various industries.

How Does a Permanent Magnetic Lifter Work

A permanent magnetic lifters works using a strong internal magnet made from NdFeB material. This magnet creates a magnetic path between the lifter and the load.

When the operator turns the manual lever to the “On” position, the magnet aligns internally and activates the lifting field. When the lever is turned to the “Off” position, the field is broken, and the load is released.

The magnetic field is strong enough to hold several times the rated capacity under the right surface and load conditions. No electricity or wiring is involved. It is a clean and simple lifting method.

Benefits of Using Our Permanent Magnetic Lifters

Simple to Operate: All our lifters use a manual handle. No extra tools or power connections are needed. Anyone can use them with basic training. 

Safer Workplace: With no cables, power supply, or electromagnetic system, the risk of short circuits or overheating is removed. The locking lever prevents accidental deactivation. 

Time-Saving: Workers can complete tasks faster. A one-person job replaces the need for a team using chains or slings. 

Lower Maintenance: Permanent magnetic lifters require no ongoing servicing. Clean the contact surface and store properly when not in use. 

Damage-Free Handling: The smooth contact prevents scratches or dents on metal sheets. Ideal for polished or painted materials.

Industries That Use Permanent Magnetic Lifters

  1. Manufacturing & Fabrication: In workshops and factories, magnetic lifters help in lifting steel plates, sheets, and components onto machines. They save time during set-up and loading. 
  2. Shipbuilding & Marine Industry: Heavy steel plates and beams used in shipbuilding are often awkward to move. Magnetic lifters allow precise positioning with minimal crew effort. 
  3. Metal Processing Plants: In metal service centres, where sheets and rods are handled daily, magnetic lifters streamline stacking and material handling. They reduce equipment wear and worker fatigue. 
  4. Warehouses & Heavy Equipment: Handling Storage and logistics centres use lifters to move ferrous parts in and out of racks, pallets, or containers. The portable nature of the equipment improves flexibility in tight spaces.

Frequently Asked Questions:

Can a permanent magnetic lifter be used for non-ferrous metals?
No. Permanent magnetic lifters only work with ferromagnetic materials like mild steel, cast iron, or certain alloys. They do not work with aluminium, copper, or stainless-steel grades that are not magnetic.
How do I determine the correct lifting capacity?

The lifting capacity depends on several factors:

  • Flat vs. Round Surface: Round bars reduce contact surface and affect holding power.
  • Surface Cleanliness: Paint, oil, or rust reduces magnetic grip.
  • Material Thickness: Thinner materials reduce lifting strength. For full capacity, the plate must be above the minimum thickness listed on the lifter’s spec sheet.

Always choose a lifter rated higher than the load weight for added safety.

Is there a safety margin?
Yes. Reputable models include a 3:1 safety factor. This means a lifter rated for 1000 kg can handle up to 3000 kg in controlled tests. This factor ensures that even with minor surface imperfections, the device performs reliably within its rated limits.
