A counter-balanced mobile device and a crane are provided. The counter-balanced mobile device comprises a counterweight rack (10), a connection assembly (20), a transmission assembly (30) and a driving member (40), wherein the counterweight rack (10) is configured to be connected with a turntable (100), and the connection assembly (20) is configured to be connected with a counterweight (200); and the connection assembly (20) is rotatably connected with the counterweight rack (10), the driving member (40) is fixed on the counterweight rack (10) and is connected with the connection assembly (20) by the transmission assembly (30) to drive the connection assembly (20) to rotate, so that the distance from the connection assembly (20) to a set reference on the counterweight rack (10) is adjusted. The counter-balanced mobile device can change the position of the counterweight (200) relative to the turntable (100) under the condition that the counterweight amount is unchanged, so that the counter-balancing performance and the stability of the crane are improved.
