PROBLEM TO BE SOLVED: To provide a load calculation system of a work vehicle which can estimate a load with a simple constitution.SOLUTION: A load calculation system 2 of a work vehicle is provided. The load calculation system 2 of the work vehicle comprises: plural actuators 71 to 73, 44 which are driven by a hydraulic pressure; a hydraulic pump 41 which supplies a pressure oil to the plural actuators 71 to 73, 44; an electric motor 60 for driving the hydraulic pump 41; a current detector 61 for detecting a current value of the electric motor 60; and a judgement part 61b which judges a load of the actuators 71 to 73, 44 based on the detected current value.SELECTED DRAWING: Figure 2
