The CR111 Project involves the Design and Construction of Defu Station and Tunnels as part of the first phase of the Singapore Cross Island Line (CRL1). The project includes the construction of Defu Station and associated tunnels, with twin tunnels of approximately 1.4km each. This project is a key component of the Singapore MRT system and will significantly improve connectivity across the island.

The project also features the use of autonomous tunnel boring machines (TBMs), specifically the first autonomous TBM in Singapore, named "Daphne", which will enhance tunneling precision, real-time monitoring, and predictive analysis.

For this project, Unicrane has supplied 2 sets of left taper ring molds and 2 sets of right taper ring molds, with the specification OD 6.9m × 1.4m × 0.3m (7+1P/R). These molds play a crucial role in the construction of tunnel sections and demonstrate Unicrane's contribution to supporting cutting-edge tunnel technology and urban infrastructure development in Singapore.
