Zusammenfassung:The blade has a hollow space extended into a platform region, and arranged in a shovel blade. A rib (36) is provided in the hollow space, and connects a pressure side wall (26) with a suction side wall (28). The rib is divided along a longitudinal direction of the shovel blade in the space. An opening (40) in the vicinity of the wall is provided in the rib up to a height of an outer fillet (34), where the opening penetrates the rib. The opening partially affects or cuts a side wall plane (44), which clamps the suction side wall and/or the pressure side wall from interior sides (42, 43).
