Provided is a mobile crane with improved working stability. The mobile crane of the present invention comprises: a support plate (11); first, second, third horizontal support frames (13, 14, 15); a vertical support frame (17); a movable frame (18); an arm (19); a drive module (23); a movable wire (25); a hook (27); and first, second, third movable wheels (31, 32, 33). First and second support modules (40, 50) are provided on the other side of each of the first and second horizontal support frames (13, 14) adjacent to the first and second movable wheels (31, 32), respectively. In addition, a third support module (60) is provided on a fourth horizontal support frame (16) extending a certain length rearward from a central portion of the other side of the third horizontal support frame (15). Accordingly, the mobile crane performs a work while maintaining a very stable fixed status.
