BOOM-ARM SEGMENT FOR A CONCRETE PUMP AND METHOD FOR PRODUCING A BOOM-ARM SEGMENT
A boom-arm segment for a concrete pump, having an upper chord (33), a lower chord (34) and two side parts (35, 36) connecting the upper chord (33) and the lower chord (34), the side parts (35, 36) each comprising a lower edge portion (43) adjacent to the lower chord (34) and a central portion (44) arranged between the lower edge portion (43) and the upper chord (33). The central portions (44) are at a greater distance from one another than the lower edge portions (43). The boom-arm segment (30) comprises an articulation connection (37) with an articulation surface (12) which defines a pivot axis (74) for a pivot connection between the boom-arm segment (21) and an adjacent structure (20), the articulation surface (12) being at least partially arranged below the plane (63) of the lower chord (34). The articulation connection (37) is connected to the central portion (44) of the first side part (35) via a first connecting support (40), the first connecting support (40) extending beyond the lower edge portion (43) of the first side part (35) without being connected to the lower edge portion (43) of the first side part (35). The invention further relates to a method for producing a boom-arm segment of this type.
