The working principle of the self propelled bogie turntable is that the electric flat car runs to the turntable, the transfer flat car does not move, the automatic rotating electric rotating self propelled bogie turntable is docked with the vertical track, so that the transfer car can run along the vertical track to achieve a 90 degree turn, which is suitable for the cross track equipment production line. The track docking precision is high, and fully automatic electrical control can be realized. The flat car can be rotated on the self propelled bogie turntable according to customer requirements, and docked with the track after the rotation. This process can solve the problem of track laying and space saving for customers. This combination allows you to move material from one floor to another more quickly, and one employee can do everything. So it will save a lot of labor and save a lot of money for customers. We can also customize the track spacing of the self propelled bogie turntable with rail track according to the customer’s needs.
