Electro magnets

The SGM Electro lifting magnets are composed of a very high magnetic permeability steel casing with sections designed with a highly safety margin for heavy duty applications.

The special bottom plate is wear – resistant manganese steel with an extra-heavy cross section. The fabricated casing has a deep welded construction by submerged arc welding. Windings are preferable manufactured with anodized aluminium strips for its electrical conductors in order to optimize volume and heat dissipation.

All elements are designed for maximum lifting performance and mechanical strength.

The result is a lifting magnet that sets new standards for performance, endurance, and reliability.

Electro permanent lifting magnets

SGM Magnetics has been designing and supplying EPRs for industrial applications since 1974 and is not only the pioneer but also the world market leader in this technology.

Electro Permanent Magnet are lifting magnets made of two different types of permanent magnet blocks which either combine their respective magnetic flows (forces) into the load during the operating mode (lifting phase) or short-circuit them into each other during the resting mode. The passage from the resting mode to the operating one and vice versa is achieved by applying a short current impulse to one of the two permanent magnets which changes its polar orientation (direction of its magnetic flow). Therefore, there is no use nor need to feed the magnet with electrical current during the operating mode.

Control panels

All the SGM lifting magnets control panels are fully designed by SGM using the most advanced electronic technology and meeting the latest regulations and norms.

Spreader Beams

Based on over 70 years of operation and a position as world leader of lifting magnets, SGM has the experience and references of a wide range of magnet spreader beam solutions. Spreader beams are designed based on the application (steel mill, port, service centre,…) and customers’ crane situations which, in case of overhead or Gantry cranes can be single hoist, one trolley with two hoists, two hoists on two independent trolleys.
