PROBLEM TO BE SOLVED: To provide a working vehicle displaying a workable range of a working machine on a display means and a floor face surrounding a traveling body as a visible image. SOLUTION: This working vehicle comprises a flexible crane 21 which is mounted to a mast 13 erected on a front part of the self-traveling traveling body 1 so as to be turnable; a load detecting means 28 detecting load applied to the flexible crane 21; turning angle detecting means 25, 26 detecting a turning angle of the flexible crane 21; a control means 11 calculating a movable range 40 of the flexible crane 21, based on the load detected by the load detecting means 28 and the turning angle detected by the turning angle detecting means 25, 26; and a light irradiating means 41 irradiating a light ray on the floor face surrounding the traveling body 1 and displaying the movable range 40 as a visible image. By performing work so as to prevent suspended load and a tool etc. from exceeding the workable range displayed on the floor face, unstable posture and falling of the traveling body 1 are prevented, and therefore, unloading work and work using a tool etc. can be safely performed.
