What Are Lifting Magnets?

Lifting Magnets

Lifting magnets provide a safe and efficient way to lift and move heavy objects in the workplace. They are also known as magnetic lifters and are made up of a controllable magnet.

Lifting magnets generate a strong magnetic field when activated in order to be used in applications in several industries where lifting large heavy ferrous objects is required.

Lifting magnets are made up of a block with a main body and a rotor, as well as two magnets in each of the main body and rotor.

When these two magnets are oriented in the same direction, they generate magnetic flux that lifts ferrous objects, but when the magnets’ orientation is reversed, the load is released because there is no magnetic pull.

One critical point is that the objects’ adhesion to the magnet should be tight, with no air trapped in between.

What Is the Difference Between Permanent and Electro-Permanent Lifting Magnets?

Electropermanent lifting magnets differ from permanent lifting magnets.

Electropermanent lifting magnets have an electric coil wound around them that passes the magnet’s electric current switch. The electric current is used to turn on and off the magnet and is then disconnected.

Advantages of Permanent Lifting Magnets

The main advantage of permanent lifting magnets is their ability to be used in a variety of industries; however, there are additional advantages to using a lifting magnet:

• No safety concerns if the operator takes all necessary precautions.

• They can lift thousands of pounds.

• Low-cost because no expensive infrastructure is required.

• Long-lasting and low-maintenance magnets; they are resistant to corrosion.

• Manually operated and simple to use; no extensive training required.

• They can lift cylindrical objects.

While all lifting magnets are capable of lifting heavy objects, they are not all the same.

Here are five things to think about when selecting a lifting magnet.

#1 Magnet Type

Different types of magnets are used in lifting magnets.
The majority of them make use of a permanent magnet.
Lifting magnets, for example, commonly use neodymium magnets.
These rare-earth magnets can generate an extremely strong magnetic field, allowing them to lift heavier objects.

#2 Lift Rating

When selecting a lifting magnet, keep the lift rating in mind. The maximum amount of weight that a lifting magnet is designed to lift is referred to as the lift rating. Some of the smaller lifting magnets can lift 200 to 400 pounds, while some of the larger lifting magnets can lift 6,000 to 13,000 pounds. Consider the application you intend to use it for and select a lifting magnet with an appropriate lift rating.

#3 Mechanism of Control

Most lifting magnets include a control mechanism. They do not always generate a magnetic field. Rather, they provide a control mechanism that allows you to turn the magnetic field on and off. When deciding on a lifting magnet, you should think about its control mechanism. Many lifting magnets are controlled by a simple lever. You can use this lever to activate or deactivate the magnetic field.

#4 Operation Temperature

The operating temperature is another factor to consider when selecting a lifting magnet. The temperature at which a lifting magnet operates is referred to as the operation temperature. The lifting magnet will operate at a temperature of less than 80 degrees if the operation temperature is less than 80 degrees.

#5 Substance

What is the material of the lifting magnet? While all lifting magnets contain a magnet, usually a high-powered neodymium magnet, they are made of different materials. Some of them are constructed of stainless steel. They have a stainless steel body with a magnet inside. Stainless steel lifting magnets are strong, long-lasting, and durable. And because of this iron alloy, they are naturally resistant to rust and corrosion. These are just a few things to think about when selecting a lifting magnet.

Lifting solutions such as magnets are used to make workers’ lives easier by eliminating the need to manually pick up and transport heavy materials. There are, however, operational guidelines for lifting magnets that must be followed.

All employees who use lifting magnets must be aware of all safety precautions.

Check out the 8 safety tips below:

#1 Review the Instructions

It is critical that employees read and understand all of the instructions in the manufacturer’s
manual before operating the lifting magnet.

#2 Strong Magnet Warning Labels

Lifting magnets should be accompanied by warning labels upon arrival.
Strong magnet warning labels should be placed near the area where the magnet is being used.
They will issue a warning to the workers who are using the lifting magnet.

#3 Remove Magnet-Affected Substances

It is critical to remove from the operational area any substances that may be affected by the magnet, such as nickel, cobalt, iron, and some rare-earth metal alloys.

#4 Put on Protective Gloves

Tapped, crushed, or pinched fingers are common injuries when using lifting magnets. Wearing protective gloves can assist the operator in remaining as safe as possible.

#5 Wear Safety Goggles

It is critical to protect one’s eyesight by wearing protective goggles. If two magnets accidentally collide, they can cause damage to each other by chipping and breaking, affecting the operator’s vision.

#6 Beware of Medical Devices

Medical Devices Should Be Avoided
Workers wearing medical devices such as aneurysm clips or pacemakers should avoid the operational area of lifting magnets because strong magnetic fields can affect their medical devices.

#7 Never stand beneath a load.

An important safety rule for workers is to never stand beneath any lifting device carrying a load; standing beneath a load increases the risk of serious injury from a falling load.
When the load is released, a split-second power spike may be enough to cause serious injury.

#8 Keep Electronic Devices Away from the Lifting Magnet

When using a lifting magnet, one precaution is to keep electronic devices, particularly mobile phones, away from the lifting magnets. Strong magnets can erase data from magnetic storage devices used in phones, computers, hard drives, flash drives, and other devices.
