LIFTING MAGNET
A lifting magnet is a device that uses magnetic force to lift and move ferromagnetic materials like steel plates, pipes, and scrap metal. It is a contactless, damage-free alternative to traditional methods like slings or clamps, used in industries such as manufacturing, construction, and recycling. Lifting magnets are available as permanent magnets (powered by internal magnets), electromagnets (powered externally), or electro-permanent magnets (used for switching the load).
How they work
- A strong magnetic field is generated to hold the ferrous object securely.
- The strength of the lift depends on the magnet’s size, the material’s thickness, and the surface area of contact.
- They are designed with a special housing and magnetic circuits to align magnetic fields and create high magnetic flux density.
Types
- Permanent magnets: Use powerful internal magnets that retain their magnetic properties long-term. They don’t require external power, making them a simple and reliable option for many applications.
- Electromagnets: Use an electric current to create a magnetic field. Power is needed to hold and release the load.
- Combine permanent magnets with a system that uses an electrical pulse to switch the load on or off.
Benefits and features
- Contactless and damage-free: They can lift and move materials without scratching or marking the surface, which is ideal for thin sheets of metal.
- Safe: Many have built-in safety features, like a locking system that prevents the load from being accidentally released.
- Efficient: They reduce setup time and allow for fast, precise material handling.
- Versatile: Different shapes are available for handling various items, such as flat pole plates for sheets and specially shaped magnets for pipes and round bars.
- High safety factor: Many are designed with a guaranteed safety factor of 3:1, meaning they can hold three times their rated load.
