In a car body, a lower travelling body of a crawler crane includes a pair of left and right crawler frames, the car body connecting the crawler frames and supporting an upper slewing body, and a pair of car body weights are disposed on front and rear sides of the car body. The car body supporting device includes a supporting mechanism for movably supporting at least one of the paired car body weights, and a drive section for moving the car body weight supported by the supporting mechanism to thereby shift a center of gravity of the lower travelling body in a front and rear direction. The car body weight supporting device can improve postural stability.
