Fully Automated Bi-Block Sleeper Production Line
NDG1800 Fully Automated Production Line Powers Bi‑Block Sleeper Manufacturing for the Sichuan–Tibet Railway’s Ya’an–Nyingchi Section
- The Ya’an–Nyingchi section of the Sichuan–Tibet Railway is a critical national project. Spanning 1,018 km in total length, this route features an exceptionally high tunnel ratio of 82.6%.
- Such demanding terrain sets an extremely high bar for construction standards, especially for sleeper quality and supply efficiency. The project requires both large‑scale output and consistent, standardised quality to keep pace with the aggressive construction timeline.
- To meet this challenge, a leading Chinese contractor selected our NDG1800 fully automated production line. The line is purpose‑built for large‑scale, standardized bi‑block sleeper manufacturing, delivering the speed, precision and reliability the project demands.
The NDG1800 line ensures full-process automation and intelligent curing.
