Abstract
A wheeled crane and self-demounting and self-mounting methods for supporting legs thereof is disclosed. The wheeled crane includes a vehicle frame and auxiliary supports, and the auxiliary supports can enable the vehicle frame to keep balance. Since the wheeled crane has auxiliary supports, when the supporting legs are demounted or mounted, the auxiliary supports function as supporting legs, so that the supporting legs can be mounted and demounted by the operation part of the wheeled crane with no need of using an auxiliary crane, and thus the self-mounting and self-demounting of the supporting legs of the wheeled crane are realized.
