YX is made of high-energy magnetic material adopting scientific magnet circuit theory featuring huge attraction force, compact, light dead-weight and convenient and safe for operation. It is an ideal energy-economizing and move convenient lifter than the electromagnet lifter which must be equipped with complicated link-up units and power supply backup. It is used to lift and transfer the normal temperature steel plates in ship-making industry, engineering mechanical industry, automobile industry and so on. There have two series of YX and YC according to their material unloading modes.
