Chennai Metro launches innovative Puller Axle System first time in the country

Chennai, India (Metro Rail Today): In a groundbreaking achievement that signals a paradigm shift in Indian metro projects, Chennai Metro Rail Limited (CMRL) has successfully introduced an advanced puller axle system for transporting and erecting a massive 30m U girder to a height of 20m. This remarkable feat, executed in the Chenani Metro Phase 2, Corridor 3 from Nehru Nagar to Sholinganallur – EV-01 (Elevated Viaduct), stands as a first-of-its-kind endeavor in the Indian metro rail construction landscape. The prestigious project has been awarded to Larson & Toubro Ltd (L&T), marking a significant milestone for CMRL and the nation's metro infrastructure.

Unveiling Innovation: The Puller Axle System

The highlight of this pioneering accomplishment is the introduction of a specially fabricated trailer designed exclusively for the Old Mahabalipuram Road (OMR) stretch. The trailer boasts 12 axles, each equipped with 8 tires, totaling an impressive 96 tires. Meticulously distributed across two axles, the puller axle not only underlines CMRL's unwavering commitment to excellence but also establishes a new benchmark in metro construction. This innovative system ensures optimal weight distribution, stability, and flexibility during the seamless transportation of the colossal 185MT U Girder.
