1. Magnetic circuits are of optimized designs, large air gap magnetic density, Aluminum coil adoption, circuit protection is made of wear and impact high-manganese steel rolling, of light weight, low energy consumption, strong lifting power and long duration.

2. Rationale insulation adopts vacuum drying and vacuum potting in order to improve the electrical and mechanical properties of the circuits. The heat-resistant level of the insulating materials is special class C.

3. Constant voltage controlling method is usually adopted, the lifting power can be improved if strong magnet controlling method is used in stead.

4. Simple concept, safety guaranteed, suitable for any kinds of lifting systems.
