Product Overview: The magnetic lifter is made with superstrong neodymium magnets, which is used for lifting steel sheet,block, rod, cylindrical and other magneticmaterial. It requires no electricity, which is widely used in theindustrial world for making steel projects move more efficiently. Each item must be tested qualified before sent outof the factory. There are more permanent magnet blocks in our magnetic lifter, so the magnetism is stronger. Product Parameter: 170084 Fit for steel plate thickness: 5mm Item net weight:9.5kg(20.9 lb) Operati ngtemperature: =80? Maximum weight capacity: 300kg(660 lb) Product Parameter: 170085 Fit for steel plate thickness: 5mm Item net weight:40kg(88lb) Operatingtemperature: =80? Maximum weight capacity: 1500kg(3300 lb) Product Parameter: 170086 Item net weight: 3.6kg(7.9 lb) Operating temperature: =80? Maximum weight capacity: 200kg(440 lb) Fit for steel plate thickness: 5MM Prodcut Features: Easy use: handle withon/off control - attach or detach material. Low residual magnetismfor rapid handling. Alloy steel galvanized lifting rings greatly improve the stability of the suction cup, making it sturdy and durable. Strong magnetic induction, stable magnetic field performance. The V-shaped groove of our permanent lift magnet is suitable for flat and round steel. When lifting flat steel, the adsorption force can reach 100%. When lifting round steel, the adsorption force is only 50% of the load. Notes: 1.Please clean the surface of the steelsheet before using it. 2.Prohibit standing under the steel sheetwhen the steel sheet is lifted.
