Steel plate electric permanent magnet sucker

Overview:

Steel plate electric permanent magnet sucker (also known as electrically controlled permanent magnet crane) is a composite magnet that combines permanent magnets and electromagnetic coils. It achieves charging and demagnetization control through brief power on, and can maintain magnetic force without continuous power supply. 

Working Principle

The electric permanent magnet lifting iron adopts a combination structure of neodymium iron boron (N35EH) and aluminum nickel cobalt (LNG60) inside, and the magnetic state is switched by changing the polarity of the aluminum nickel cobalt through the excitation coil. When working, electricity is applied to align the aluminum nickel cobalt magnetic poles in the same direction as the neodymium iron boron magnetic poles, generating suction force; Reverse current is applied during demagnetization to cancel out the magnetic poles of the two, achieving safe demagnetization.  ‌

Applicable scenarios

Mainly used for lifting and handling iron materials such as steel plates and coils, suitable for industries such as mechanical processing, shipbuilding, and warehousing. Its advantages include: safety and energy saving: the charging and demagnetization process only requires a brief power on, reducing energy consumption by more than 90%, and there is no risk of power outage or demagnetization

Quick response: Remote operation through the electrical control box, integrated magnetization detection and safety protection functions

Precise control: magnetic circuit air gap ≤ 2mm, supports high-precision adsorption

Principle of joint hoisting arrangement

Distance calculation: When lifting medium thick plates (6-32mm), the distance between the electromagnets is taken as 3-4 meters, and the length of the protruding parts at both ends is half of the distance.

Anti deformation measures: Multiple electromagnets need to be arranged in a staggered manner along the length of the steel plate to increase the adsorption area and disperse the force.

Operation control function

Magnetic adjustment system: Adjust the suction force through a matching rectifier control cabinet to adapt to different steel plate thicknesses and numbers.

Single plate placement: Supports jog operation to release steel plates one by one.

Security protection: equipped with power-off magnetic protection function to prevent power outage accidents.

Special scenario handling

Ultra wide/ultra long steel plate: It is recommended to use small circular lifting electromagnets or electric permanent magnets for steel plates with a width exceeding 3000mm.

High temperature environment: The 400 model can be customized with a high temperature resistant version (≤ 700 ℃).

Extension suggestion: For non-standard requirements (such as ultra long steel plates), you can contact the supplier to customize permanent magnet cranes or electric permanent magnet lifting devices
