Electric Cargo Handler Rail Wagon With Flatbed

The working principle for electric cargo handler rail wagon with flatbed:
the power source ac 380 is transformed into 36v by the transformer put on the ground, connecting with two rails respectively. Then the carbon brushes mounted on the wheels take the power from the rails to current rectifier for rectifying into dc 36v. The dc 36v gets to dc motor to control the electric cargo handler rail wagon work.
when the running distance is longer than 70m, it is necessary to add transformer for increasing the rail voltage. ( for making up the voltage dropping)
advantages: the bdgz series electric cargo handler rail wagon has advantages: it can be used for high frequency and long time with high security and flexible features. It has no limitation about running distance, which can be used in occasions such as s-shape or arc-shape rail and high temperature environments.
the bdgz electric cargo handler rail wagon doesn't use cable, so it won't be impacted by the cable (it is free from cable), and worker needn't to pull or draw the cable in case of injuring it.
Disadvantages: the rail needs to be insulated of erection with high strict security requirement.
