KEC Tests New U-Girder Launcher for Delhi Metro’s Phase 4
Back on February 6, engineers from CCECC – KEC JV performed a load test on a new unique type of U-girder transporter & launcher for building a 12.375 km elevated extension of Line-8 (Magenta Line) between Vikaspuri Ramp and Haiderpur-Badli Mor Station.
The team had started launching 28m U-girders on this section of the 65.1 km Phase 4 project in November 2020 using help from Apollo Cranes – a local mobile crane company which, like crane companies all over India from Mumbai to Kanpur, deploy two mobile cranes for night launches.
To speed things up in challenging site conditions – J Kumar Infraprojects in 2020 deployed a giant straddle carrier on the streets of Mumbai to build the city’s Line-6 project. And now in Delhi, CCECC – KEC will soon be deploying a double truss (or double-nosed) launcher by mumbai-based SNM (SN Mercantile) Group.
KEC’s Package DC-01 also consists of 10 elevated stations at Keshopur, Paschim Vihar, Peeragarhi, Mangolpuri, West Enclave, Pushpanjali, Deepali Chowk, Madhuban Chowk, Prashant Vihar & North Pitampura. This package combined with other civil packages will form a 28.92 km extension of Line-8 from Janakpuri West towards RK Ashram.
Here are some snaps shared by Swapnil Bhandare of a load test with a 165 ton U-girder in action:
I haven’t been able to find a good video demonstrating how it’ll work, but this video (with graphics straight from the 90s) comes close enough:
Similar launchers are expected to be deployed for constructing the 508 km Mumbai – Ahmedabad High Speed Rail project for which the first concrete pour to officially launch construction work took place just last week.

What’s the status of Vikaspuri Ramp tp Peeragari section of This extension?. Last time I heard that work was stopped due to lack of environmental clearance. Since then, there’s no update, whether they resume the work or not.
Don’t have an update on that. Need to check.
Sucks for Apollo Cranes haha 😕
