Balanced cantilever erection with launching gantry
VSL has over 20 years of experiences with design and construction of precast segmental balanced cantilever bridges.VSL has the capability and necessary experience to work with designers and contractors to develop cost effective designs that promote safe, effective construction sequences and methods, while achieving optimal productivity.
The balanced cantilever erection with launching gantry offers savings in lifting equipment. Bridge segments are delivered along completed deck, and most works proceed above the terrain as well, therefore no disruption is caused to existing traffic. All temporary loads are introduced directly into piers.
VSL has worked with general contractors on many significant projects and is recognised as a world leader in this technology. VSL´s highly efficient erection systems enable contractors to reduce the construction schedules for segmental bridges. VSL regularly achieves the erection rate of up to 6 segments per shift, i.e. the productivity exceeding one cantilever per week.
