A unique mechanism isolates the operating handle while the load is suspended. This ensures the load will not be released while the lifter is under tension. Every lifting magnet has a Safe Working Load (SWL) rating, which is three times less than the actual test load that the lifter has to lift before leaving the factory. Powerful - Constructed using ultra high performance neodymium magnets. Safe - A 3:1 safety factor. Zero Running Costs - Permanent magnet technology requires no energy source. Flexible - 2 pole design enables use on flat and round material. Fast - The Ultralift safely lifts ferrous components in seconds. Floor Saving - Goods are stored closer together - access is needed to the top face only. Gentle - Goods are not marked or damaged.
