"Revolutionizing Construction: The Innovative Trolley Behind the La Pesa Viaduct" The winged trolley is an auxiliary means of construction that had not been used in Panama until now, which is a significant development in the region. The La Pesa viaduct in La Chorrera marks a milestone in Panamanian construction as it uses a unique construction method by Grupo Puentes. This 1,750 m long viaduct is part of a project to rehabilitate and widen 5 km of the Pan-American Highway, featuring 6 lanes for long-distance travel and 4 local lanes underneath. The construction method involves two phases: the first phase uses portal formwork to execute the core section, while the second phase employs a specialized trolley for the cantilevers and slab. Among other advantages, it acts as a collective protection measure to prevent workers from falling to different levels and minimizes the impact on traffic during the construction phase by not having to interrupt the passage of vehicles underneath it. This method allows progress to be made with a yield of 3 sections of 12m in length each week once the trolley reaches optimum performance. The La Chorrera Viaduct is divided into 41 spans with an average length of 43 m each, a total deck width of 26.50 m and a constant 3.50 m edge. At the head of the piers there are pendular bearings, which absorb seismic loads with better results than conventional neoprene bearings. video rights : grupopuentes #viaduct #bridge #bridgeconstruction #movableformwork #engineering #civilengineering #construction #civilconstruction #engenharia #engenhariacivil
