1. Within the working range of the lifting electromagnet, (R<5M) is not allowed to stand.
2. When the lifting electromagnet is lowered, it must not fall, so as not to damage the coil.
3. Metals with a temperature above 200 degrees Celsius are generally not allowed to be lifted. When lifting a metal of 300 degrees Celsius - 700 degrees Celsius, a lifting electromagnet with a special heat sink should be used.
4. When the lifting electromagnet is in continuous operation, it should not exceed 8h in summer and 12h in winter to prevent the coil from overheating and burning.
