What Is a Magnetic Lifter?
A magnetic lifter is a device that utilizes powerful electromagnets for lifting and transporting metal products, materials, and scrap. They come in various types, including permanent magnets, electromagnets, and battery-operated models, each selected based on specific applications. Magnetic lifters are essential in industries such as recycling, steel mills, and manufacturing facilities handling steel. Some models can even be attached to excavators or used underwater, and they are often colloquially referred to as “Lifma” or “Lifmag.”
Uses of Magnetic Lifters
Magnetic lifters are primarily used in steel mills for lifting and transporting steel plates and pressed products. In recycling plants, they are employed for handling metal scrap and chips from machine tools. The lifting capacity of these devices varies based on the type of magnet and the size and materials they can handle. It’s important to select the right magnet type for safe and efficient operation, as the adsorption force can be affected by factors such as dust and dirt.
Principle of Magnetic Lifters
Magnetic lifters come in different types, each with unique features:
- Permanent Magnet Type: Compact with high magnetic force and no power supply required, making them safe during power outages. However, they lack remote operability.
- Electromagnetic Type: Offers adjustable magnetic force, allowing for specific transport capacities and remote operation. Drawbacks include high power consumption and fall risks during power outages.
- Permanent Electromagnetic Type: Combines the features of both permanent and electromagnetic types, using power only for attaching and detaching, thus ensuring safety during power outages and reducing power consumption.
- Battery Type: Offers wireless operation, providing high mobility and eliminating disconnection concerns.
Each type of magnetic lifter has its specific applications and advantages, making them versatile tools in various industrial settings.
