Lifting magnets play a very important role in heavy industrial environments that deal day in and day out with the task of moving big metallic objects. They offer safe, efficient, and reliable methods for the handling of ferromagnetic materials like iron, steel, and alloys without using slings, hooks, or chains. These have revolutionised material handling in sectors such as steel, construction, shipbuilding, automotive, and scrap recycling. But before understanding their benefits in these sectors, it is important to know how lifting magnets work and what makes them indispensable in modern industry.
Understanding Lifting Magnets
Lifting magnets are magnetic devices used in lifting and moving ferrous metal loads through the action of a magnetic force, which is created either by a permanent magnet or an electromagnet. Unlike mechanical lifting systems, which essentially clamp or grip the loads, these lifting magnets eliminate any direct contact with the metal surface and therefore reduce wear and any possibility of damage.
In general, there are two types: permanent and electromagnetic. Permanent magnets use natural magnetic fields for the provision of unyielding attraction in applications where a constant power supply is not available. Electromagnetic lifters generate a magnetic force with the help of an electric current, and, as such, they are able to be turned on or off, allowing more flexibility with the magnet. This makes them especially helpful in dynamic operations where high degrees of precision and control are needed.
How Do Lifting Magnets Work?
The principles behind how a lifting magnet works deal with the very basics of magnetism. Most lifter magnets generate the magnetic field either by a current-carrying coil-as in the case of electromagnets by a powerful permanent magnet. When brought into proximity with a ferrous metal object, the field penetrates the surface, aligning the domains of the metal and thereby producing an attractive force.
An electromagnetic lifter switches the field on or off by properly regulating the electric current to it. When on, the magnetic field clutches onto the metallic load for lifting or moving around safely; when the current is turned off, it gets demagnetised and instantly drops the load. This simple and effective mechanism provides safety during operation, high efficiency in lifting the load, and minimum handling time.
Permanent industrial lifting magnets use no electricity, instead drawing on the powerful neodymium or ferrite magnets for the same lifting capability continuously. They may be used in static or back-up operations where power interruptions might be an issue.
Types of Lifting Magnets and Their Uses
There are several types of lifting magnets, each designed to fulfil certain operational needs.
- Permanent Lifting Magnets: These are suitable for small loads and can be used in workshops or machine shops. They require no power and have a simple lever mechanism to engage or disengage the magnetic field.
- Electromagnetic Lifters: These find wide application in large-scale industries that require heavy amounts of lifting quite frequently. The electromagnetic lifter provides a high amount of lifting power, hence finding a perfect application in the handling of steel plates, coils, and scraps. This ability to turn the on/off magnetic force provides full control over the operations.
Efficient Lifting with Crane Magnets
Crane magnets are very often installed on an overhead crane or gantry in steel mills, fabrication shops, shipyards, and foundries for the efficient lifting of large plates or structural parts. A crane magnet ensures smoother operations, reduces dependency on manual labour or slings, hence improving productivity and safety.
Applications of Industrial Lifting Magnets
The applications of industrial lifting magnets can be seen in the following fields. The versatility within the field of industrial lifting magnets has made the magnet irreplaceable in several industries.
Steel and Metal Processing: Used for handling sheets, slabs, bars, and coils.
Scrap and Recycling: Suitable for sorting, transferring, and loading ferrous scrap materials.
Shipbuilding: Required in the raising of heavy steel plates while constructing the hull of a ship.
Manufacturing: Useful in an assembly line for holding or moving ferrous parts.
Warehousing: Helps in stacking and moving metallic inventory efficiently.
These magnets eliminate mechanical gripping and slinging, which, in turn, reduce damage to surfaces and increase workplace safety. Capable of operating quickly, they further ensure faster loading and unloading times for improved throughput.
