Magnetic lifters are naturally versatile and it works in the roughest manner. It is used for moving a variety of ferrous metals ranging from small bundles of rod or scrap to large, heavy blocks. Lifting magnets are great for advantages related to both quality and labor. Using these techniques, you can improve overall productivity by allowing a single person to lift a load of metals. It lessens the labor and time of the work which otherwise you might have needed two or more people the old way. Magnetic lifters whether electric or permanent have the rated capacity mentioned on the nameplate. The trick is to move the load safely, and to do that the equipment needs to be properly specified and applied. If the magnet is being used on a material that is thinner than the material it was rated on, the capacity will be reduced. It might be used in multiples on beams to augment the amount capable of being lifted.Tel (360) 647 - 8438Toll-Free (800) 965 - 4968Fax (360) 539 -1850E-mail [email protected] 700 Sunset Pond Lane, Suite #cBellingham, WA 98226Website: http://www.armsmag.com/lifting-magnets.htm
