In modern industrial sectors, the transportation and handling of steel plates are routine operations. Traditionally, many enterprises use steel wire ropes as the main lifting tool for hoisting large steel plates. However, with the improvement of safety production awareness and technological development, the industry has increasingly recognized the potential risks brought by steel wire ropes during lifting. Therefore, this article proposes adopting electro-permanent magnetic lifting tools to improve the safety and efficiency of steel plate hoisting operations.

Although widely used, steel wire ropes have obvious disadvantages in lifting steel plates. First of all, the use of steel wire ropes imposes high requirements on operators, who must exercise precise control to prevent steel plates from tipping and slipping and causing injuries. Secondly, wear and damage to steel wire ropes may lead to unexpected breakage and further result in safety accidents. In addition, steel wire ropes are greatly affected by external environments. Factors such as corrosion and humidity will weaken their safety performance. Lifting steel plates with steel wire ropes requires repeated adjustment of binding positions to maintain balance and stability, which not only affects operational efficiency but also increases operational complexity and safety risks.

By contrast, electro-permanent magnetic lifting tools, as modern lifting equipment, have distinct advantages. Working on electromagnetic principles, electro-permanent magnetic lifting tools generate magnetic force under electric control to realize stable adsorption of steel plates. They are easy to operate and can quickly adsorb and release workpieces within a short time, greatly improving operational efficiency. More importantly, the magnetism of electro-permanent magnetic lifting tools is electrically controlled, avoiding improper handling caused by human errors. In case of power failure or system fault, the permanent magnet can still maintain holding force to guarantee the safety of steel plate hoisting.

In terms of safety, equipped with a closed-loop control system, electro-permanent magnetic lifting tools can monitor the operating status in real time and ensure stable magnetic force throughout the hoisting process, thus reducing the risk of accidents caused by lifting equipment failures. Besides, the working surface of electro-permanent magnetic lifting tools closely fits steel plates, which greatly reduces dangerous operating space and lowers the possibility of operator injuries.

From an economic perspective, although the initial investment cost of electro-permanent magnetic lifting tools may be higher than that of traditional lifting equipment, enterprises will achieve remarkable cost savings and benefit growth in the long run considering their advantages in operational efficiency, safety and maintenance costs.

In summary, using electro-permanent magnetic lifting tools to hoist steel plates can not only significantly improve the safety and efficiency of handling operations, but also conform to the development trend of industrial upgrading and technological innovation. To ensure on-site operation safety and improve production efficiency, enterprises in the industry are recommended to update equipment and switch to electro-permanent magnetic lifting tools to achieve safe and efficient hoisting of steel plates.
