Abstract Research purposes ： As a special lifting equipment，railway crane speed in train marshalling and towing state has a great significance for railway rescue. NS1003 railway crane is taken as the object of study, when it runs through the railway bridges along the way in marshalling and towing state, the effect of axle load and wheelbase changing on running speed on bridges is analyzed, to provide analysis method for railway crane design in the future.
Research conclusions ： When the main structure and gravity center position of the crane are confirmed, the bogie wheelbase can be adjusted to improve its echo performance. If the product design cycle is short, first design the whole machine structure, finally adjust the parameters of the crane to improve its echo performance. If the product design cycle is long, constantly optimize the crane design, use the method which adjusting the weight and gravity center location of the crane and crane bogie wheelbase and axle load, to get ideal crane echo performance.
