Self-launching Erection Machines for Precast Concrete Bridges

Construction of precast concrete bridges with spans ranging from 100 to over 600 ft is mostly based on use of self-launching machines. The launching units are complex and delicate structures that resist high loads on long spans under the same constraints that the obstruction to overpass exerts on the final structure, and are also adaptable for reuse on different projects.
