The permanent magnet use principle
The internal use of the high performance permanent magnetic materials of neodymium borax, can produce a strong suction in the magnetic circuit, the magnetic field lines so that the jack handle turn at work or in a closed state;
The utility model is a novel lifting tool with the advantages of safety, energy saving and high efficiency without external power supply.When Jack is working, Jack at the bottom of the lifting surface of the longitudinal magnetic pole, will hold firmly the iron workpiece material, and V shaped groove on the bottom surface, thus to ceiling plate shaped workpiece, also can absorb the hanging cylindrical workpiece. The jack of sheet thickness and area have strict requirements.
The working principle of permanent magnet lifting jack is the use of the principle of Faraday electromagnetic induction to manufacturing.
