The invention provides a counterweight moving apparatus and a crane. The counterweight moving apparatus comprises a swing part (10), a first end of the swing part (10) comprises a counterweight connection part; a supporting part (20), wherein the supporting part (20) is hinged to a middle section of the swing part (10); and a driving part (30), which is connected to a second end of the swing part (10) and is capable of driving the swing part to swing around the supporting part (20) so as to make the swing part (10) to have an external swinging position and a recovery position. A technical scheme of the present invention can effectively solve the problems that flexibility of engineering machinery counterweight is not strong and engineering machinery performance is easily restricted in prior art.
