description	The utility model relates to the technical field of cranes, in particular to a frame structure and a crawler crane, which comprise a frame, a crane body is arranged on the upper surface of a frame body, a base is welded on the lower surface of the frame, two welding frames are welded at the bottom of the base, and a turntable is welded at the bottoms of the welding frames. A supporting mechanism is arranged on the upper surface of the rotating disc, a shrinking mechanism is arranged at the bottom of the rotating disc, and crawler belt sets are arranged on the front portion and the rear portionof the frame. According to the frame structure and the crawler crane, the pushing cylinder is started to extend out to control the two crawler groups to move relatively, so that the gap size betweenthe two crawler groups is adjusted, the movement of road sections with different widths is adjusted conveniently, the crane can travel and move conveniently, the whole crane is suitable for moving invarious different environme
