The RTCL-YX01 gearbox oil washing machine is a specialized equipment designed for the maintenance of high-speed trains. It is suitable for cleaning the internal parts of the gearboxes of all standard-gauge high-speed train models.

The drive and oil supply utilize frequency conversion technology, achieving stepless speed regulation for gearbox oil washing. A programmable curve method ensures that the wheelset speed and oil supply change according to the programmed curve during the oil washing process, overcoming the problems of oil shortage and overflow caused by oil quantity variations at different speeds. This ensures that different high-speed train wheelsets and gearboxes can be cleaned on the same machine.
