The proper maintenance and inspection of magnetic lifting devices are crucial to ensure safety in industrial settings. A competent person should conduct thorough examinations periodically, with suitable intervals between each examination. Devices categorized as 'lifting equipment' require thorough examinations every 12 months, while those classified as 'lifting accessories' should undergo inspection every 6 months. Alternatively, a competent person may include the examination of the device as part of a written inspection regimen.

Adhering to the manufacturer's instructions for regular inspection and maintenance is essential. Here are key aspects to include in inspection and maintenance schedules:

• power cables to the magnet - check for damage and ensure that they are properly supported
• magnet assembly - check for damage to the suspension points and that retaining bolts are kept tight
• magnet face – check for any damage to the face which might affect performance

• magnet - check for deterioration of insulation resistance; check the value of coil resistance to ensure that "inter-turn" faults have not developed whilst in use
• electrical plug and socket connectors - check that mechanical strength, insulation and electrical conductivity are being maintained
• lifting accessories e.g. chains, links etc associated with the magnet - thoroughly examine at appropriate intervals
• electrical back-up batteries - check their condition and that the battery back-up alarm works when the power is off.
• control boxes/pendants – check for damage, legibility of control labels, correct function of controls including audible and visible warning devices.
• Magnetic adhesion – periodic verification by inserting a ‘test piece’ of non-metallic material between the magnet and the material. It should still be possible to pick up the load with the test piece inserted.

Visual damage to the bottom face and body of the magnet poses significant risks, including load drop, electrical injuries, and coil damage. Prompt action is necessary in such cases. Don't hesitate to consult your lifting partner for repair or replacement of electromagnets.

Safety should always be a top priority in industrial operations, and regular inspection and maintenance of electromagnetic lifting equipment are essential to uphold this standard.
