The difference and choice between electromagnetic crane and permanent magnet crane

In modern industrial processing and production operations, เครนแม่เหล็กไฟฟ้า and permanent magnet cranes are two commonly used spreaders for handling metal objects, which can improve lifting and handling efficiency and production safety. Many enterprise users do not know how to choose permanent magnet crane or electromagnetic crane. Our editor summarized the difference between electromagnetic crane and permanent magnet crane for the reference of the majority of users.

1.  Permanent magnet cranes can only be used to lift normal temperature materials in normal temperature environments, so permanent magnet cranes can be selected in normal temperature environments; electromagnetic cranes are used for lifting normal temperature materials in very temperature environments and very warm materials in normal temperature environments;
2.  Electromagnetic hoisting should be selected when special hoisting is required. Electromagnetic hoisting can realize multiple hoisting methods by adjusting the size of the current, such as multiple suction and multiple release, multiple suction single or separate release, single suction Single sheet release, etc.; permanent magnet hoist is generally only used for lifting and transporting single sheet steel;
3.  In the occasions with high automation requirements, the lifting is frequent and the lifting intensity is high. Choose the electromagnetic crane. The electromagnetic crane can control the magnetic force by controlling the current and the current on and off. The operation is simple and efficient; while the permanent magnet crane It is controlled by the principle of mechanical lever, automatic control of suction and release of steel plates or manual control, which has low efficiency and is not suitable for occasions with frequent lifting;
4.  When lifting steel plates with different lengths, choose electromagnetic cranes. Because of their good applicability, permanent magnet cranes are less suitable;

Precautions:

The permanent magnet hoist does not need electricity and uses permanent magnets as power. It has the advantages of convenient use, energy saving, safety, light weight, less maintenance, and low price. However, the efficiency is low and the applicability is poor; the electromagnetic hoist is efficient High, strong applicability, easy to use and other advantages, but also need electric energy, the system needs to be maintained, when the enterprise chooses electromagnetic crane, it needs to be equipped with a power outage magnetism control system to ensure safety in the event of a sudden power outage, so the price is higher.

When choosing an electromagnetic spreader, enterprise users should choose according to the actual working conditions, and must not make mistakes in special occasions to reduce costs or blindly pursue efficiency, and choose unsuitable spreaders.
