Abstract: The current research on combination of excavator and truck failed to integrate the technical and economic factors, as well as various options cannot be quantitatively compared. To this end, this paper introduces equipment combination ability index and annual conversion cost, by calculating the cost efficiency, it is come true to integrate the technical and economic factors and quantify the results, so as to ensure the best match of excavator and truck.
