Modular Frame Concept Cart for Inspection of Slab-On-Girder Bridge Superstructure


Accessibility of bridge superstructures is often a major issue for the cost-effective inspection and for the installation of health monitoring systems. Depending on the case studies under consideration, tailored solutions may be required to best suit particular needs. This paper presents a concept cart that has been conceived, designed and built to allow a minimum of two operators to move along the whole length of the steel I-girders of a 263 m five span continuous slab-on-girder bridge. the vehicle has been equipped with a set of built-in devices, used to rapidly pass through the transverse stiffeners and cross frames, also at the bent locations. This solution allowed the successful installation of a 1.1 km fiber optic circuit for strain and temperature monitoring.
