Poland 104D Tunnel Project is located in southern Poland (section D: Limanowa – Klęczany siding) and carried out by Gülermak in consortium with Budimex. It is part of the broader modernization and electrification of railway line No. 104 (Chabówka – Nowy Sącz) under the Podłęże-Piekiełko project. Key words include constructing two parallel tunnels each about 3.8km long, improving travel times and regional connectivity.

For this project, Unicrane has supplied 3 sets of molds with specification OD 10.5m × 2.0m × 0.4m (6+1P/R) and 6 sets with OD 4.5m × 1.2m × 0.25m (6+1P/R). This delivery supports one of Poland's most ambitious railway tunnel works, reinforcing our capability in large-meter and varied ring-types mold design and manufacture.
