This series of carts is powered by cable drums. It is a combination of electric rail shuttles, electric rail tractors and non-powered rail vehicles, and can realize automatic docking between tractors and non-powered vehicles. Scope of use: spray paint rooms, sandblasting rooms, paint rooms, heat treatment, and various high-temperature, high-humidity, explosion-proof and other harsh environment processes or places.

KPJ series cable drum electric rail transfer cart use 380V power through cables and rely on the winding device on the flat car to realize flat car power supply. The winding device is placed under the rail transfer cart, and the power is directly controlled by the AC control system to start, stop, advance, retreat, speed regulation, etc. of the motor. The operating system of the flat car is controlled by a low-voltage 36V power supply; hydraulic or mechanical lifting systems and other devices are allowed to be installed on the flat car table; automatic remote control can be realized.

This series of transfer carts can be used in harsh environments such as high temperature, low temperature, and explosion-proof.

Cable drum electric rail transfer cart adopts a box beam structure, which has strong bearing capacity, no deformation, simple structure, low cost, and low requirements for track laying. It is a common track flat car for workshops. Compared with the KPX series flat cars, it is not limited by the use time. Compared with the KPD series transfer carts, it has low requirements for track laying. Cable drum electric rail transfer cart is suitable for any load and high frequency of use. For running distances exceeding 50 meters, a wire arranging device is required to lay and wind the wire. The running distance can meet 200 meters.
