The aim of CRAMIC is to develop a new technology for the rail tracks of cranes used to warehouse containers in international ports or to handle bulk materials in mines or ports. The work of these cranes, which until now was assumed to be static or cyclical, is becoming more and more dynamic because of increases in speed and loads, thereby increasing wear on the rail tracks. The resulting dynamic effects have become preponderant. They are poorly controlled and can no longer be overlooked in designing future facilities.
The project has three intertwined goals, as follows : (i) to control and quantify the impacts of these dynamic effects, which stem from multiple causes; (ii) to rescale and develop new rail track technologies based on the foregoing outcomes; and (iii) to equip the facilities with data acquisition systems in order to keep track of distortions, in view of longer-term maintenance.
