Products Introduce Steel coil transfer vehicle is adapted to transport steel coils, aluminum coils, iron roll and a series of profiles package as a delivery device. This transfer vehicle is also known as a rail flat vehicle, which is one kind of special transfer vehicle. A U-shaped device shall be installed on the vehcle to prevent some roll steel coils, aluminum coils and other rolling profiles and ensure hundred percent safety during transport. Its motor is controlled by frequency to not only prevent the moment of starting current too large from scrolling of package profiles, But also to ensure the life of the motor. Working Principle The steel coil transfer vehicle is pwered by low voltage railway. The power supply makes the AC 380v power is transformed into AC 36v two-phase and are respectively connected to the two rails. The steel coil transfer vehicle's wheels and conducting plate lead the AC 36v electricity to the electrical appliance box which is installed on the steel coil transfer vehicle, the AC 36v is transformed into DC 380v through the transformer. The controls AC Metallurgy motor through AC control system to make the steel coil transfer vehicle starting, stopping, going forward, going backward and adjusting the running speed, etc. url:http://www.newld-transfercar.com
