A Lifting Magnets Guide for Cranes: Types, Manufacturers
Introduction
Lifting Magnets, also called Hoist Magnets, are the important parts of cranes. They play a crucial role in the efficient and safe handling of heavy loads in steel industry. There is a brief description of the three main types and the comparison in the following:
Electromagnetic Lifting Magnets(Electromagnets):
This type is the most widely used one in crane industry. They use an electric current to generate a magnetic field, allowing them to attract and lift ferrous materials. Key features:
- Variable lifting capacity: The lifting capacity can be adjusted by controlling the current flowing through the magnet coil.
- Quick and easy activation: The magnet can be turned on and off rapidly, facilitating efficient material handling.
- Demagnetization risk: In case of power failure or equipment malfunction, there is a possibility of losing the magnetic force and dropping the load.
Permanent Lifting Magnets:
They have a fixed magnetic field and do not require an external power source to operate. Key features:
- No power supply needed: Permanent magnets do not require electricity, making them more energy-efficient and reliable.
- Constant magnetic force: The magnetic force remains consistent without the need for continuous adjustment.
- Limited lifting capacity: Permanent magnets typically have lower lifting capacities compared to electromagnetic magnets.
- Cannot be deactivated: The magnetic force cannot be turned off, which may pose challenges when releasing or controlling the load.
Electro-Permanent Lifting Magnets:
This type uses an electric pulse to activate the magnet and then maintains the magnetic force without the need for a continuous power supply. Key features:
- Power efficiency: They consume power only during the activation and deactivation phases, reducing overall energy consumption.
- High lifting capacity: Electro-permanent magnets can achieve higher lifting capacities compared to permanent magnets.
- Reversible magnetic force: The magnet can be turned on and off electronically, providing more control over the lifting operation.
- Complex control systems: Electro-permanent magnets require sophisticated control systems to ensure proper activation and deactivation.

Kanetec’s compact structure and DGCRANE’s professionally customized design make them stand out in the market.
Ultimately, the choice of manufacturer depends on your unique requirements. Each manufacturer offers a variety of lifting magnet types, but for the crane industry, DGCRANE might be your better choice to finish the lifting task.
FAQs about Hoist Magnets
- Q: Are lifting or hoist magnets suitable for lifting non-ferrous materials?
A: No, they are specifically designed for lifting ferrous materials that are attracted to magnets. They are not suitable for lifting non-ferrous materials such as aluminum or copper. - Q: Can electromagnets be used in underwater lifting applications?
A: Yes, there are electromagnets designed explicitly for underwater lifting. They are constructed with waterproof materials and can safely operate in submerged conditions. - Q: What safety precautions should be taken when using hoist magnets?
A: When using hoist magnets, it is essential to follow safety guidelines. Operators should ensure proper training, regularly inspect the magnets for damage, and use appropriate lifting techniques to avoid accidents.
Conclusion
It is crucial to consult with experts, such as crane manufacturers or electromagnet suppliers, to assess your specific lifting requirements accurately. They can provide detailed information and assist in selecting the appropriate electromagnet model for your crane, taking into account factors such as load weight, application environment, and crane specifications.
