Abstract
To provide a frame of construction machines that can enhance the rigidity of support members. The frame comprises a bottom plate, a pair of vertical plates being disposed spacedly in a width direction on a top surface of the bottom plate and extending longitudinally and vertically, and multiple support members extending toward outside in a width direction from breadthwise outer surface of the pair of vertical plates. At least one of the multiple support members comprises a vertical wall perpendicular to the bottom plate. A breadthwise inner end part of vertical wall is welded on breadthwise outer surface of one of pair of vertical plates. A lower end of the pair of vertical plates is welded intermittently on a top surface of the bottom plate, and there exists a non-welded part where the lower end of the vertical plates is not welded on the top surface of the bottom plate under breadthwise inner end part of the vertical wall.
