The turntable is designed to transport vehicles across the track and can be rotated 60 degrees, 90 degrees and 120 degrees in factories to achieve rapid adjustment of railway vehicles. The working principle is that: the guide rail is also mounted on the turntable, When the rail transport vehicle is running on the turntable, the turntable can be rotated automatically or manually until it is accurately attached to the target rail and then the transport vehicle is running on the vertical rail. The turntable is suitable for a variety of applications, such as round rails, vertical rails, cross rails, and more. The turntable system runs smoothly and has high rail connection accuracy, the PLC can be installed to meet fully automated electrical operation.
