Magnetic Systems

Permanent magnetic lifters are more commonly preferred to be used for lifting steel plates as they do leave little marks or scratches on the object surface in contrast to clamps and hooks. A permanent magnet that’s capable of generating a larger magnetic field than a normal magnet is referred to as lifting magnets. Permanent magnets achieve this capability due to the compositions of alloys and some rare earth metals like ferrite. With the advent of technology, permanent magnets come with ON/OFF switches so they can be turned off while not in operation. These lifting magnets have become a very viable and efficient solution in situations where huge metal plates, disks, tubes etc are to be lifted.

MAG-AUTOBLOK TECNOMAGNETE SPA is synonymous with magnetism in the industrial field. It began its activity in 1974, and since then it has become specialized in permanent-electromagnetic technology applied in machine tool field. With headquarters in Italy, close to Milan, they have branches in USA, Germany, France and China, active commercially and with post-sales support.

Safety, efficiency and energy saving are common features of all their advanced lifting solutions from heavy duty applications on cranes at ports, steel plants and yards to the loading/unloading of steel parts on machineries, automatic manufacturing lines or manipulators. 

Technology behind this magnet are the Quadsystem technology, invented by them in the 80s and hinge of their production, consists of a permanent-electro magnetic circuit with alternating poles N / S arranged in a checkerboard, positioned inside a magnetically neutral frame. Each pole is constituted by a steel core, by a reversible polarity magnet (Alnico) and by high potential magnets (Neodymium). Acting on the reversible magnet in a few moments by an electrical pulse, the magnetic field moves from the inside towards the outside of the system (and vice versa).

This technology offers great advantages over other magnetic configurations.
1) Permanent Electro Safety
Electric power is only needed for the activation (MAG) and deactivation (DEMAG); an electrical pulse of a few fractions of a second magnetizes the system, after which the piece remains clamped with constant force, without any power consumption. A subsequent electrical pulse allows the demagnetization and the workpiece removal.

2) Bi-Directional and Neutral Crown circuit for maximum performance

The checkerboard square morphology allows a horizontal and flattened circulation flow, totally concentrated in the polar area, i.e. on the workpiece to be clamped. The harmony between North and South poles surfaces ensures a perfect balance of flows without magnetic dispersions, with reliable and consistent performances.

3) Respect for the environment

The permanent-electro magnetism is a clean technology, since it does not release harmful substances, does not require lubricants or chemical components which must be disposed of, and does not produce residues. Electricity consumption is limited to the few seconds required for activation and deactivation of the system.

Advantages Of Permanent Magnetic Lifters

Permanent Magnetic  Lifters Offer A Wide Range Of Applications In Various Industries And Offer The Following Advantages:
