Abstract
A revolving frame includes a center frame and a plurality of beams welded to a side surface of the center frame and extending away from the center frame along a transverse direction. The plurality of beams includes a skirt beam that includes a pair of beam side plates having a first end that is welded to the side surface of the center frame. An upper surface of each beam side plate has a notch surface that extends from the first end to a notch edge. The notch surface defines a notch groove, such that the notch edge of each beam side plate is separated from the center frame along the transverse direction by a gap across the notch groove. The skirt beam further includes a beam upper plate integrally fixed to the pair of beam side plates, and a notch connection plate welded to each beam side plate.
