To provide a counterweight device for a general mobile crane capable of easily and safely attaching it to an upper structure and capable of generating a high counterweight moment during operation.SOLUTION: A mobile crane comprises a movable chassis, an upper structure rotatably attached to the chassis, and a counterweight device 20 connectable to the upper structure. The counterweight device comprises at least one connection element 30 where the connection element lifts a counterweight base plate 22 and the counterweight device 20, and connects the counterweight device to the upper structure. The connection element is connected to the counterweight base plate 22 and extended substantially perpendicular to the counterweight base plate 22.SELECTED DRAWING: Figure 2
