D evelopment of electro-hydraulic proportional power match system for transporting girder vehicle ’s driving Abstract: On the basis of analysis of the theory of mechanical-hydraulic power match system,the electro-hydraulic proportional power match system which is suitable for matching TLC900 transporting girder vehicle of the engine is developed according to the driving force-speed curve and parameter,and the control rule and program flow chart about it are put and practice have indicated that the power match system satisfies the capability requirements of the transporting girder vehicle and is of great significance to improve performance and efficiency of the transporting girder vehicle;meanwhile it is useful for other huge driving construction machineries. Keywords: transporting girder vehicle,hydraulic system,engine,power match,electro-hydraulic proportional 1. Introduction Transporting girder vehicle is developed specially for rail passenger transport special line,and its largest load is 900 girder vehicle is applied to transport the concrete girder from prefabricated ground to bridgework spot and cooperates with spanning bridge machine to plish the ,transporting girder vehicle can also transport the spanning bridge machine to achieve the short-distance transportation between bridge,which meets the requirement of sp
