Description
Dedicated Span-by-Span Erection Equipment for Rapid Bridge Construction Engineered for the highly efficient “span-by-span” methodology, this specialized equipment functions as an integral part of the segment erection system. It features a heavy-duty supporting truss or specialized lifting gantry designed to suspend and align an entire span of precast concrete segments (from one pier to the next) simultaneously. With a modular structure for rapid deployment and automated post-tensioning alignment systems, it delivers multi-hundred-ton lifting capacity, offering unparalleled precision and speed in assembling massive elevated structures without intermediate ground support.
Applications
Maximizing Efficiency in Standardized Viaducts and Urban Rail Projects The primary application of Span-by-Span Erection Equipment is in projects with standardized, repeated span lengths, particularly for multi-kilometer highway viaducts and urban elevated rail transits (LRT/MRT). It excels in environments where speed, consistency, and minimal ground disruption are paramount. By assembling an entire span at once and applying post-tensioning, it radically shortens construction cycles compared to segmental cantilever methods. In dense urban areas or over existing transportation corridors, it enables “top-down” construction, allowing bridge decks to advance span-by-span without closing busy streets or disrupting utilities. It is the definitive solution for high-throughput, industrial-scale bridge deployment.
