  "textContent": "[Problem to be solved] Provided is a crane vehicle capable of preventing another vehicle from coming into contact with a tip end portion of a boom when entering an intersection or the like. [0002] [Solution] A controller 60 of a crane vehicle detects an obstacle on a lateral side of a tip end portion of a boom 42 by using left and right cameras 46 and 47 when the vehicle enters an intersection or the like. When it is determined that a detected obstacle may come into contact with the tip end portion of the boom 42, the controller 60 drives a brake device 70 to stop a crane vehicle 10, and causes a speaker 66 to output a warning sound. When it is determined that there is no risk of contact with the boom 42 as the detected obstacle stops, or moves away from the crane vehicle 10 by turning left or right, or passing an intersection, the controller 60 releases the driving of the brake device to enable travelling of the crane vehicle 10.",
