We are offering permanent magnet lifter. permanent load lifting magnets capacity: 100 - 6000 kg (flat material) ideal tools for easy, quick and thus economical transport of heavy objects made of ferro-magnetic material. The load is not affected mechanically which allows lifting of flat as well as round material. the permanent magnets do not require electric energy and will leave only minor residual magnetism on the material after use. designed for thick, non-flexing materialpermanent lift magnets are ideal for handling steel plates, die castings, forgings, etc. They eliminate the need for clamping devices, slings or chains. One person can perform operations previously calling for two or more people. less torque required to release partlift capacity clearly stated on magnetjack screw secondary releasedurable stainless steel casinguse only on thick, non-flexing ferrous items3:1 design factor
