Magnet cranes

Magnet cranes

Magnet overhead cranes use magnetism to lift loads, either to increase productivity or safety, or to lift parts that have no anchoring points.

The magnet crane is a lifting device equipped with a magnet hoist or a standard hoist fitted with a magnet as an accessory. It can therefore be used exclusively for this application, or as a hybrid.

There are 2 main types of magnet: electromagnet or permanent magnet.

The electromagnet is a technology that magnetizes the magnet when electric current is supplied. Then, when the power is cut off, the magnet demagnetizes. Activation and deactivation of the magnetism is rapid, and its power can vary.

Advantages of the electromagnet :

  • Quick to magnetize and demagnetize (higher productivity)
  • Magnetic power dimming from 0% to 100% is quick and easy
  • Technology is easily accessible
  • Affordable

Permanent magnet overhead cranes

The permanent magnet is a different technology. Electrical energy is sent to the magnet for a few seconds to change its polarity. Once the magnet is magnetized, it no longer requires power to remain magnetized. Current must be sent to the magnet again to reverse its polarity and demagnetize it.

Advantages of permanent magnets :
  • Less energy-consuming (economical)
  • In the event of a power cut, the charge is maintained thanks to permanent magnetism. No battery system required.
  • Reduced maintenance, as fewer electrical components are required.

Applications and technological solutions :

This type of equipment can be used for many applications and has several advantages:

  • For handling scrap metal without anchoring points,
  • For greater efficiency in high-volume production, by saving slinging time,
  • Greater safety, by avoiding human intervention during loading and unloading,
  • To save storage space, by eliminating the need for an employee to intervene during loading and unloading.

 

There are many possible solutions, all of which can be combined:

  • Intelligent load limiters
  • Magnet groups
  • Magnet power selection
  • Independent activation of magnet groups
  • Anti-sway systems (Accessories & safety/anti-sway)
  • Integrated crane remote control, including safety functions

Can my crane be equipped with a
magnet system?

Contrary to initial perceptions, it's not enough to buy a standard crane and magnets as accessories and then combine them. This type of equipment has its own mechanical and electrical design, and this must be taken into account when manufacturing it. This requires combined expertise in overhead cranes, magnet systems and integration. Consult your manufacturer to ensure that integration fully meets your needs.
