Lifting electromagnets

43

Another name for a lifting electromagnet is an electromagnet washer. It allows you to lift and move sheet metal and other materials with metal in the composition:

  • slabs;
  • ingots;
  • scrap metal;
  • metal flakes and shot;
  • products from ferromagnetic alloys.

Depending on the type of transported metal products, electromagnets of various modifications can be used: rectangular, round, and saddle-shaped. Washers differ not only in shape, but also in standard sizes. The "Krankomplekt" company, which produces similar load-lifting devices, offers their manufacture in individual sizes (you can find out more on the page https://krankomplekt.com/gruzozahvat/shajby/).

Field of application of electromagnetic washers

The type and dimensions of the electromagnetic washer also depend on the crane on which it will be used. It can be used on bridge, portal, gantry and self-propelled cranes. The type of enterprise is also important, since it depends on the type of production that will be transported with the help of a lifting electromagnet. Washers of various modifications have become widespread:

  • at metallurgical plants;
  • shipbuilding and ship repair plants;
  • machine-building enterprises;
  • ferroalloy plants, portals and terminals;
  • enterprises for the processing of ferrous and non-ferrous scrap.

Design features of load-lifting electromagnets

Today, electromagnetic washers, which are closest to the "Soviet" models in terms of size and magnetization strength, have found wider use:

  • magnetic washers M-22B, M-42B and M-62B;
  • rectangular electromagnets PM-15 and PM-25A.

The design of electromagnets is high-strength, which allows you to use washers for work in difficult conditions. Electromagnets withstand mechanical impact when falling on a load and shocks when it is attracted. The design of electromagnetic washers is thought out to the smallest detail:

  • The coil, placed inside the case, is closed from below by a non-magnetic element in the form of a plate.
  • There are voids between the body and the coil, but they are filled with a polymer that makes the attachment of parts reliable.
  • Each electromagnet is equipped with three chains, which have one common ring, which is put on the hook of the crane.

To ensure even greater safety, the electromagnet is equipped with a cable drum. It prevents cable sagging and breakage. Electromagnets can be used not only separately, but also together. To do this, they are attached to a special magnetic traverse.
