* LG - Launching Gantries Span length: 20 – 100+m Usual Length: Minimum 600 - 800 segments Usual cycle time / span 1-2 days / span LAUNCHING GANTRY After STRUKTURAS entered the segmental market, expressions like “glue-as-you-go” and “turnaround” have been well recognized world-wide as cost time saving solutions for erecting segmental bridges. Design experience through various projects have led to development of sophisticated equipment capable of meeting the most challenging segmental bridge designs to date. Solutions to complex geometry and space restrictions enable both designers and contractors increased flexibility in their design and construction. These include erecting several parallel spans on varying vertical elevation and horizontal radius down to 75m.
