A permanent lifting magnet is a very useful piece of lifting equipment, particularly within areas where steel is handled. They are also frequently used in ship yards, scrap yards and steel workshops. Permanent lifting magnets are best for lifting and handling steel sheets however they are also able to lift cylindrical steel though the lifting capacity for cylindrical objects will be much reduced when comparing to flat sheets due to the fact that it will have a much smaller contact area with the magnet.
Magnetic plate lifters are an easy to use and very cost efficient means of lifting ferro-magnetic materials as they require no power and virtually no maintenance, keeping the magnet clean is imperative, especially the magnetic plates; however you should have them tested and inspected by an authorised person at least every 12 months to ensure their continued safety.
Lifting magnets work manually, requiring no power supply and are easily operated by a single person. The magnet is usually attached to a crane of some type, or high beam through the use of a lifting hoist which allows the magnet to be raised and lowered as needed. The magnet is placed onto the steel sheet, centrally in line with the centre of gravity if just 1 magnet is being used, more than one lifting magnet can be used on the same steel sheet which enables longer lengths to be lifted, this is a very common practice in steel plants, however if more than one magnet is to be used then you should use a spreader beam with a magnet at each end, equally distanced from the centre of gravity to enable both magnets to be raised at the same time to keep the load stable.
It is the lever which is locked down to create the magnetic connection, this applies the strong magnetic force required to lift the steel sheet. This connection is permanent until the lever is raised and the connection is released. Thanks to modern technology, safety locking mechanisms will guarantee that an accidental release will not occur; further adding to the stringent health standards required within a commercial or industrial environment.
Permanent lifting magnets are an excellent one-off investment that will provide years of continual use. They are available in a variety of models with numerous lifting increments, all models will have a minimum thickness of steel which they are able to lift safely so pay close attention to this figure as using a magnet to lift steel with less than the stated minimum will have a great impact on the safety of the lift.
One of the main benefit of using permanent lifting magnets is that they are easily transportable plus can be used more or less anywhere; they are uncomplicated to use, have low maintenance costs, and are economical to purchase, especially when you buy from Lifting Gear Direct, where we can also carry out the necessary yearly inspections, carried out by one of our experienced engineers.
