To provide a crane vehicle capable of manually releasing the fixation of a ladder easily and manually fixing the ladder again even if some failure occurs in a driving device for moving a pin for fixing the ladder.SOLUTION: A pin 111 is held by a holding device 112 to be slidable between a locked position where a ladder 50 is fixed and a non-locked position where the ladder 50 is not fixed. The pin 111 is connected to a lever member 121 through a chain 143. The lever member 121 is held by holding pieces 125, 126 to be slidable and rotatable between a first position and a second position. When a second driving device for driving the pin 111 fails, an operator hooks his/her finger on a second piece 123 of the lever member 121 to move the lever member 121 to the second position from the first position. Then, the lever member 121 is rotated such that the second piece 123 of the lever member 121 is hooked on an engagement protrusion 141.SELECTED DRAWING: Figure 9
