Imagine a 103-metre-span bridge suspended midway across a 50-metre-deep gorge, hanging on two points from a ropeway cable crane. What sounds like an impossible feat became reality in Mizoram, India, where one of the country’s first steel network-tied arch bridges was launched using a ropeway cable-crane system—a probable world first in bridge construction. The operation also sets a probable world record for the heaviest point load (220 tons) ever transported over a cable crane.

Located between Lengpui Airport and Aizawl, the bridge site presented extreme challenges—flash-flood-prone terrain, seismic Zone V classification, and a 50 m-deep gorge. Conventional erection or launching methods were unfeasible. Engineers at Force SE Pvt. Ltd. devised an indigenously engineered ropeway-based cable-crane system, featuring twin towers, pulleys, winches, and lifting beams, designed entirely in India.

In this webinar, Deepak Prajapati, Co-Founder and Director at Force SE, will take you behind the scenes of this groundbreaking project—covering the engineering design evolution, system development, load testing, and the flawless six-hour launch that redefined how bridges can be built in challenging terrains.
