Electro-permanent magnet (EPM) lifters play an important role in modern industry due to their high efficiency and safety, but it is an important technical challenge to maintain safe control of the lifted goods in case of unstable power supply or sudden power failure. This paper explores methods and strategies to ensure safe control of electro-permanent magnet (EPM) lifters in such emergency situations.

Firstly, it is necessary to introduce a safety emergency system into the design and manufacture of an electro-permanent magnet lifter.Such a system is automatically activated in the event of a sudden interruption of power supply and uses an inbuilt battery or supercapacitor to maintain a magnetic force sufficient to hold the load until it is safely placed. This function, known as holding power, is an important safety feature in the design of an electro-permanent magnet lifter.

Secondly, it is vital for operators of electro-permanent magnetic lifters to be trained to operate in emergency situations. This includes how to use the manual emergency release in the event of a power failure and how to deal with overloading or abnormal situations. In addition, operators must have a clear understanding of the standard inspection steps that should be carried out before each operation to identify any issues that could lead to safety risks.

In addition, regular maintenance and inspection of the electro-permanent magnet lifter ensures that the back-up power supply is adequate and capable of providing the necessary energy when required. This reduces the number of safety issues that can arise due to equipment failure. Maintenance records should be well documented so that they can be tracked and analysed to prevent potential problems.

Finally, standard operating procedures and contingency plans for the operation of electric permanent magnet spreaders are established to ensure that in the event of sudden power failure or other emergencies, staff members are able to respond clearly and reduce accidents caused by panic or improper operation.
