Self-launching gantries, movable scaffolding and form travellers, designed around your span arrangement rather than adapted to it. Every machine is engineered, built, trial-assembled and commissioned by the same team.
Position
A viaduct is built by the machine that erects it. Span length, pier geometry, segment weight, headroom and the alignment radius all sit inside one equation, and the moment a contractor tries to force a standard gantry onto a non-standard alignment the programme starts leaking days. IBEC designs the machine to the deck. We take the span arrangement, the segment schedule and the site constraints, and return a launching scheme with the erection cycle time already proven on paper.
Applications
Each system is engineered to the job in front of it. The figures below are the working envelope, not a catalogue limit.
Span-by-span erection of precast segments from above, where the alignment is clear overhead and piers can carry the launching reactions.
The answer to restricted headroom — running below deck level under live traffic, overhead lines or an existing structure.
Cast-in-situ span-by-span construction where precasting yards are not viable. Available overhead and underslung, with organic prestressing on the longer configurations.
Balanced cantilever construction over water, deep valleys and live rail, where nothing can be supported from the ground.
Launching nose, sliding bearings, guides and jacking plant for decks pushed out from a casting bed behind the abutment.
Getting segments from the casting yard to the gantry: stacking, transport and pick-up equipment sized to the segment schedule.
Strand jacking, hydraulic gantries and skidding tracks for single-lift erection of trusses, arches and complete spans.
