Disclosed are a counter-balanced mobile device and a crane. The counter-balanced mobile device comprises a counter-balanced carriage (10), a connecting assembly (20), a transmission assembly (30), and a driving part (40), wherein the counter-balanced carriage (10) is configured to be connected to a rotary platform (100), the connecting assembly (20) is configured to be connected to a counter-weight (200), the connecting assembly (20) is rotatably connected to the counter-balanced carriage (10), and the driving part (40) is fixed on the counter-balanced carriage (10) and is connected to the connecting assembly (20) by means of the transmission assembly (30) to drive the connecting assembly (20) to rotate so as to the adjust the distance from the connecting assembly (20) to a set reference on the counter-balanced carriage (10). The counter-balanced mobile device can change the position of the counter-weight (200) relative to the rotary platform (100) without changing the counter-weight, thereby improving the counter-balancing performance and the stability of the crane.
