KPDZ
KPDZ series raliway flat carts are powered by low voltage electricity from the railways. The power source AC 380v is transformed into AC 36v two-phase and are respectively connected to the two rails. Then the flat car’s wheels conduct the AC 36v on rail into the electrical appliance box at the bottom of the carts; then the AC 36v is transformed into DC 36v and then control the DC motor through the DC control system to make the flat carts start, stop, go forward and backward and adjust the speed and so on.
KPDZ flat carts can be used both on the “S” and arc-shaped railways. They also can be used in the high-temperature environment. The hydraulic lifting device can be installed on the flat carts. But this series has strict requirements on the construction of the railways which need to be insulated. The rated load can not be more than 50T. This series flat carts are suitable to be used in such conditions higher using frequency, middle and long distance transportation. The running distance is not limited, but with a running distance of more than 70 meters (230ft.), you need to increase the number of transformers to compensate for the track voltage drop.
