The invention discloses a counterweight device of a crane and the crane with the counterweight device. The counterweight device of the crane comprises: a counterweight; a first guide rail, which is installed on the main body of the crane in a movable manner, used for supporting the counterweight and guiding the counterweight to move along the first guide rail, and capable of moving in a forward inclining state or in a backward inclining state, wherein in the forward inclining state, the counterweight moves forward along the first guide rail under the action of the gravity of the counterweight, and in the backward inclining state, the counterweight moves backward along the first guide rail under the action of the gravity of the counterweight; and a first drive unit, which is used for driving the first guide rail to move in the forward inclining state or in the backward inclining state. Since the guide rail which is capable of inclining forward and backward, the counterweight can move forward and backward along the first guide rail under the action of the gravity of the counterweight so as to adapt to different working states. In a lifting state, the counterweight moves backward, and maximum lifting weight is increased; and in a zero load state, the counterweight moves forward, and the center distribution of the whole crane is uniform, which enables the stability of the crane to be improved.
