2nd Launching Gantry Commissioned for Nagpur Metro’s NS Line

With another string of piers ready on Wardha Road, NCC Ltd. on December 19 commissioned their 2nd launching gantry crane close to the National Environmental Engineering Research Institute (NEERI) at Ajni Square for building the 7 km Reach-1 section of Nagpur Metro’s 19.658 km north-south line towards the Nagpur Airport Station.

NCC had earlier set up the project’s first launching gantry just south of the Nagpur Airport in July 2016, commissioned it in early August 2016 and thereafter began rapidly launching precast segments to build the elevated line’s spans and viaduct.

One interesting thing to note is that the segment was integrated & cast along with a parapet wall (unique in Indian metros) which has helped to reduce the cost of purchasing separate casting molds and transporting individual parapet segments on-site, thereby cutting down on the overall construction time. An image from inside the casting yard can be viewed here.

Here’s my go-to video to demonstrate how the Launching Gantry works its magic with precast segments to build modern segmental viaducts and bridges:

Going forward, I’ll be posting one-off construction images on Twitter so do follow or check out my handle.
