Lifting magnets are used to move and position ferromagnetic (often steel) work pieces of various shapes and lengths quickly and without damage. They save valuable storage space and time.
Lifting magnets use electromagnets or permanent magnets, or a combination of both. The advantage of electromagnets is that they can lift large weights (up to 15 tonnes) and can be switched remotely. A disadvantage is that they can drop the load if the power fails. Therefore all electromagnetic lifting systems have a backup system that holds the load for 20 minutes after a power cut-out. This backup system is expensive and must be inspected annually. As an alternative, Goudsmit also sells both mechanically and electrically switchable permanent magnets. These maintain their magnetic force and do not require a backup system.
