The power supply and lighting of mobile screw unloader manufacturers should select the products suitable for port handling machinery

All electrical equipment of mobile screw ship unloader manufacturers meet the national standards, and the imported equipment regulations comply with IEC standards. The selection of electrical equipment is suitable for port handling machinery. According to the principle of advanced technology, low energy consumption and economy, the electrical equipment of mobile screw ship unloader is selected. Electrical equipment shall be selected according to dust, moisture and enzyme proof conditions. ABB or Siemens products are preferred for frequency converter and electronic control components.

The installation of electrical equipment and circuit of mobile screw ship unloader adopts anti loosing measures. On board power supply of the mobile screw ship unloader the power supply of the screw ship unloader is 380V, three-phase, 50 Hz cable, which supplies power to the machine through the cable drum. The power supply is from the 380V power box on the wharf. The connection box is supplied with the screw unloader.
