The permanent magnet jacks of the PML model series are mainly used to hold plate-shaped or cylindrical iron material workpieces during lifting. It has the characteristics of light structure, convenient operation, strong holding force, safety and reliability, etc., and is conducive to improving labor efficiency Therefore, it has been widely used as a lifting tool in factories, docks, warehouses and transportation industries.

PML series permanent magnet jacks use high -performance permanent magnetic material of neodymium iron boron, which produces a strong holding force in the magnetic circuit With the help of the handle, the jack mandrel can be put into operation or closed without external power supply,' When the jack is in working state, the holding surface at the bottom of the jack forms a pair of longitudinal magnetic poles, which firmly holds the workpiece of iron material. The holding surface is also made with a V-shaped groove, so it can hold both Plate-shaped workpieces can also hold cylindrical workpieces.
