What is Magnetic Lifter

Magnetic Lifters are high-powered magnetic devices that are used to help lift heavy objects. Technically speaking, a magnetic lifter, magnet lifter or lifting magnet, as they are often known, is a piece of lifting device used to lift objects such as steel and other metals; however, stainless steel is not magnetic due to the metal's structure.Often, an operator places the lifting magnet over the metal application and then activates the magnet so it lifts the object. Once activated, the magnet will hold the object until the lifting process is finalised. The direct current generates an electromagnetic field that maintains an attractive force. This force is really strong but if interrupted it will drop the load. A battery can be used in this case to avoid such events from happening.

Types of Magnetic Lifter

Permanent Magnetic Lifters
A permanent magnetic lifter is a lifting device that utilizes permanent magnets to lift and transport ferrous materials. Their permanent magnets are often made of neodymium or ferrite, capable of attracting and holding onto ferrous objects. Unlike electromagnetic lifters that require an electric current to create a magnetic field, permanent magnetic lifters have a fixed magnetic field that is always present. These units are safer since they don't require electricity, reducing concerns about power surges or outages. They are compact and easy to move from different areas. Besides, they are particularly useful in environments where a continuous power source may be impractical or where simplicity and reliability are essential.

Electromagnet Lifters
It primarily consists of an electromagnet. An electromagnet is a specific magnet formed by running an electric current through a coiled wire. The electromagnet lifter lifts steel objects when the current is activated and lowers them when the current is deactivated. However, it relies on an electrical current for operation. Generally operated with DC power, it needs a chuck controller. Some, like Guangdar's battery-type magnetic lifter, are battery-operated. It has the control panel integrated into the lifting magnet, reducing the need for an additional check controller.

How to Choose Magnetic Lifter

Understand Application Requirements
Before purchasing a magnetic lifter, it is crucial to have a thorough understanding of the application requirements. Start by identifying the type, size, shape, and material of the workpieces for which the lifter will be used. This will help determine the appropriate magnetic lifting capacity needed for the lifter.

Lifting capacity
Evaluate the maximum load you need to lift to determine the appropriate lifting capacity of the magnetic lifter. Additionally, consider the required lifting height and transportation distance. These factors will help you choose the suitable magnetic lifter to meet your needs.

Work Environment Conditions
It is important to consider the temperature and humidity levels of the work environment when purchasing a magnetic lifter, as these conditions can significantly affect the lifter's performance. Besides, the materials used in the lifter must be resistant to moisture, corrosion, and other adverse factors that may be present in the workplace.

Rated Load Maximum Value
Consider the rated load maximum value. This value represents the maximum weight that the lifter is capable of lifting. However, it is not enough to look at this value when purchasing. It is recommended that the required suction force be specified to ensure that the lifter can safely and effectively lift the intended workpiece.In addition to the required suction force, it is important to consider the surface condition and smoothness of the workpiece. If the workpiece has a rough or uneven surface, increasing the required suction force may be necessary to ensure a secure hold.

Magnetic Lifter How It Works?

Though most magnetic lifters tend to have slightly different designs, the general concept is the same. Each magnetic lifter contains powerful neodymium magnets inside a metal housing. When been switched on, magnetic strength is released to absorb the load to be lifted. To unload the part, just switch it off.

Magnetic lifters can be strong enough to carry all sorts of ferromagnetic materials, including heavy metal sheets and beams. Some could even be designed with a small groove cut underneath to help grab onto irregular steel parts, like tubes or pipes.

The working part of lifting magnet comes from its magnetic field strength, which could be generated by different means, either electricity or a lever switch.

How to use Magnetic Lifter?

Inspect the Lifter

Before use, inspect the magnetic lifter for any damage or wear.
Ensure that all components, including the magnet, control panel, and lifting mechanism, are in good condition.

Check the Load

Verify that the material you intend to lift is ferrous (contains iron or steel) and within the weight capacity of the magnetic lifter.

Prepare the Surface

The lifting surface should be clean and free from oil, grease, or any debris that may affect the magnet's adhesion.

Power On

Connect the magnetic lifter to a power source according to the manufacturer's instructions.Turn on the control panel to activate the electromagnetic force.

Position the Lifter

Position the magnetic lifter directly over the load, ensuring proper alignment.

Activate the Magnet

Use the control panel to activate the magnet. The electromagnetic force will securely attach the lifter to the ferrous material.

Lift the Load

Slowly lift the load by operating the lifting mechanism on the lifter.
Be cautious and ensure that the load is stable before moving it.

Transport the Load

Move the load to the desired location while monitoring its stability.

How to Maintain Magnetic Lifter

Store your lifting magnet in a dry, secure location when it is not in use.

Regularly inspect your lifting magnet for any signs of damage or wear, such as cracks or chipped magnets. Stop using the magnet immediately and consult a professional for repairs if you notice any issues.

Keep your lifting magnet clean by wiping it down with a damp cloth and drying it thoroughly after each use. This will help to prevent rust and other types of damage.

Avoid exposing your lifting magnet to extreme temperatures or moisture, as this can affect its performance and reduce its lifespan.

Use your lifting magnet only for its intended purpose, and follow the manufacturer's instructions for proper use. This will help to ensure that you use the magnet safely and effectively.

What are The Precautions for The Use of Permanent Magnetic Lifter?

When the temperature of the steel plate exceeds 60°C, the lifting operation should be stopped immediately, because too high temperature will cause demagnetization of the permanent magnet crane, which will affect its magnetic force and cause the steel plate to fall during use.

During the lifting process, it is strictly forbidden for irrelevant personnel to stay and walk back and forth at the lower part of the permanent magnet crane and the steel plate, so as to prevent accidents during the lifting process and cause too many personal injuries.

When irrelevant substances such as dust and debris appear on the suction surface, the holding force between the jack and the steel will be reduced, and it is easy to cause the steel holding effect to be unstable or fall.

After using the permanent magnetic lifter, it should be stored in a dry and ventilated place in time to prevent the humid environment from affecting its external materials.
