Geomatic Techniques for Monitoring and Verifying of the Wear Condition of the Runways of the Bridge Cranes

Monitoring and diagnostics of the lifting systems in the field of rail transport play a fundamental role in order to enable it to function safely providing any deviations from the expected behaviour of the regular conditions. The transit of heavy convoys naturally tends to worsen the geometrical position and, of consequence, it is necessary to identify some monitoring techniques that allow to establish the maintenance of infrastructure in accordance with the standards UNI ISO 9927-1 and in according to ISO 12488-1 must be verify the tolerance for wheels and travel and traversing tracks; for a crane runway these are for example the span, the position and height of the rails.. Especially the ground infrastructure related to the bridge crane requires periodic checks. The purpose of this paper is to identify suitable geomatics techniques for monitoring of the runways of the bridge cranes. To achieve this aim, the paper is divided in more sections. In the first part, the paper describes the area involved in the monitoring and standards in the field of monitoring the wear of the rails. In the second part, the paper describes the criteria and regulations for checking the wear of the bridge cranes using several geomatics techniques, tool and software
