KPD series is a low voltage rail 36V power supply motorized transfer trolley. It is equipped with Slippery Touch Line Power Supply System, Single phase AC 380V is steped-down to a single phase 36V safe voltage with Step-down transformer. AC 380V is transformed into AC 36V by way of transformer and then sent to the flat transfer car by rail touch line. And the rail transfer cart makes the voltage step up to single phase AC 380V through the step-up transformer on it.

The rail can be divided into light rail,heavy rail and crane railway.Different type motorized transfer carts demand to mount the different rails. In general, the load of the rail car is below the 20t, light rail can be chosen.The material is Q235,55Q, the specification is P24,which mean the rail weight is 24kg per meter. The load of the rail car is below 100t, we suggest to use heavy rail.The material is 45MN,71MN, the specification is P38 and P43. The load of motorized transfer car is above the 100t, choose generally the crane rail .The material is U71MN,the specification is QU80.
