When lifting steel plates with electro-permanent magnetic lifting tools, multiple factors must be considered and properly operated to ensure safety and high efficiency.

First, when selecting an electro-permanent magnetic lifting tool, a proper model and specification must be chosen according to parameters such as the specification, weight and shape of the steel plate. The magnetic force of the lifting tool shall be sufficient to bear the weight of the steel plate without excessive redundancy, so as to save energy and costs.

Second, inspect the electro-permanent magnetic lifting tool carefully before lifting. Check whether the pole surface is flat, free of debris and damage, whether the magnetism of magnetic poles is normal, and whether the control system is sensitive and reliable.

During lifting, operators must receive professional training and be familiar with the operating methods and safety regulations of the lifting tool. Start lifting smoothly and avoid rapid acceleration or deceleration to prevent the steel plate from shaking or falling off.

Make sure there are no obstacles on the lifting route and enough space for the lifting tool and steel plate to pass through. Meanwhile, pay attention to the influence of ambient temperature and humidity on the magnetic force of the lifting tool, and avoid operations under extreme conditions.

In addition, regular maintenance of electro-permanent magnetic lifting tools is critical. Replace worn parts in a timely manner, clean the pole surfaces, calibrate and test the control system to keep the lifting tool in good working condition at all times.

In conclusion, only by strictly controlling all links including model selection, inspection, operation, environmental control and maintenance can we ensure the safe and efficient lifting of steel plates using electro-permanent magnetic lifting tools.
