The Ya’an-Nyingchi section of the Sichuan-Tibet Railway is a critical national project. Spanning 1,018km with an 82.6% tunnel ratio, its high construction standards demand exceptional sleeper quality and supply efficiency. To meet this challenge, a leading Chinese contractor selected our NDG1800 fully automated production line for large-scale, standardized bi-block sleeper manufacturing.
The NDG1800 line ensures full-process automation and intelligent curing.
- Its 12 pit-kilns provide precise 45°C steam curing in 12-hour cycles.
- Integrated with temperature sensors and PLC control, the system enables accurate regulation and full process traceability.
- This complete automation significantly enhances both production efficiency and quality consistency.
This successful deployment proves our advanced equipment meets the demands of landmark rail projects. We are proud to deliver a reliable production solution for our partner and to further solidify our expertise in transportation infrastructure.
