什么是永磁起重器？
Magnetic lifter, also referred as?lifting magnet, is primarily used across several industries to hoist and move ferrous workpiece with flat or round surfaces. Magnetic lifter can be further divided to permanent magnetic lifter and electromagnetic lifter according to the source of magnetic power. Electromagnetic lifter is typically criticized for power consumption, serious heating, hysteresis phenomenon, large size, and maintain. Instead, permanent magnet lifter has compact structure, low operation difficulty, and no power consumption. The lifting capacity of permanent magnetic lifter is also determined by material, thickness, surface quality of load.
