The low-voltage rail transfer cart is powered by the rail, the 380V AC power supply is reduced by the transformer to a 36V safe AC voltage.
According to work requirements, the load is less than 50 T and connected to the two rails, the 36-volt AC is introduced into the vehicle electrical box through the wheels. The control system converts to DC, and controls the DC motor start, stop, advance, retreat, and adjustment speed of the vehicle.
