Electro‑permanent magnetic lifters play a vital role in modern industry with high efficiency and safety performance. However, how to maintain safe control of suspended loads under unstable power supply or sudden power outages remains a key technical challenge. This article discusses methods and strategies to ensure the safe operation of electro‑permanent magnetic lifters under such emergency conditions.

First, it is essential to integrate an emergency safety system during the design and manufacturing process of electro‑permanent magnetic lifters. The system activates automatically upon sudden power failure and maintains magnetic holding force through built‑in batteries or supercapacitors, securing the load until it is safely placed. This residual holding force function serves as a critical safety feature of electro‑permanent magnetic lifter design.

Second, emergency operation training is indispensable for operators. Training covers the use of manual emergency release devices after power failure, as well as the handling of overloads and abnormal working conditions. In addition, operators must fully master standard pre‑operation inspection procedures to identify potential safety hazards before lifting.

Furthermore, regular maintenance and inspection are required to ensure backup power units are fully charged and capable of providing emergency energy support whenever needed. This effectively reduces safety risks caused by equipment failure. Detailed maintenance records should be kept for traceability, analysis and potential fault prevention.

Finally, standardized operating procedures and dedicated emergency response plans must be established. In the event of sudden power outages or other emergencies, clear guidelines enable staff to respond correctly and avoid accidents caused by panic or improper operation.
