The rail operated ladle transfer car has been new favorite in the industry transport field all over the world with hot market. Especially for the workshop transportation. Working Principle The power source AC 380v is transformed into AC 36v two-phase and are respectively connected to the two rails. Then the rail operated ladle transfer car conduct the AC 36v on rail into the electrical appliance box at the bottom of the rail operated ladle transfer cars. And then the AC 36v is transformed into DC 36v and then control the DC motor through the DC control system to make the rail operated ladle transfer cars start, stop, go forward and backward and adjust the speed and so on.
