KPDZ Transfer Trolley. Its power is supplied with single-phase 36V low voltage unit. DC motor drive.
The working principle : AC 380V is transformed into AC 36V by way of transformer, and then sent to the current rectifier on the truck, which supply 36V direct current to DC motor.
Advantage: Rails are electricity conductor instead of cable. You need not worry about rail circuit impacted, and staffs wouldn't care about pulling or drawing cable in case of injuring themselves.
Shortage: erection requirement is very stringent, and transporting distance is within 60 meter. Beyond the range, you need to add another transformer for lower AC 380V to 36V to the line.
