Goudsmit's powerful new neodymium magnet gripper

Dutch magnetic technology firm Goudsmit has designed a ‘powerful’ new magnetic power gripper suitable for picking up or gripping heavy ferromagnetic parts from 6 mm, such as solid steel beams, grilles, plates or milled parts.

The compact neodymium magnet is also suitable for use as a handling magnet in robotic applications or with plasma cutting machines in the metal industry, according to Goudsmit.

The permanent magnet can be pneumatically controlled using compressed air and a 5/3 valve. 'This makes it extra safe, because the magnet retains the load even in the event of a loss of compressed air,' the manufacturer explains.

'Maintenance free'

Goudsmit points out that a 115 mm power gripper lifts a load of about 175 kg and has a holding force of 527 kg. The unit is available in three sizes: Ø50, Ø75 and Ø115 mm. The magnet is said to be robust and pretty much 'maintenance free', meaning that it has a very long life.

Goudsmit adds that two or even three grippers can be coupled together.

Switch on and off

'What makes this system so special is that it is very powerful when switched on and has no residual magnetism when switched off,' the Dutch company remarks.

'The advantage of switchable permanent lifting magnets is that they do not require a back-up system for potential power failures and can therefore safely lift heavy loads,' it goes on to state.
