A mobile crane includes a counterweight carrier capable of traveling following a movement of a crane main body, the counterweight carrier including a carrier main body on which a counterweight is loaded and a wheel unit attached to the carrier main body and including wheels, a wheel driving device configured to rotate the wheels to thereby cause the counterweight carrier to travel, a loadage detector configured to detect a weight loadage index value, which is an index value of weight of the counterweight loaded on the carrier main body, and a controller configured to cause the wheel driving device to change a driving force of the wheel driving device for rotating the wheels such that the driving force increases as the weight loadage index value detected by the loadage detector increases.
