BOOM-ARM SEGMENT FOR A CONCRETE PUMP
The invention relates to a boom-arm segment, comprising 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 boom-arm segment (30) comprises a hinge connection (62) which defines a pivot axis (74) for a pivot connection between the boom-arm segment (21) and an adjacent structure (20), wherein: the pivot axis (74) is located below the plane (63) of the lower chord (34); a transition piece (64) is located between the lower chord (34) and the hinge connection (62), and the connection (65) between the transition piece (64) and the lower chord (34) is spaced apart from the adjacent end (61) of the lower chord (34); the transition piece (64) is enclosed between a first reinforcement part (40) and a second reinforcement part (70) which laterally adjoin the transition piece (64); the reinforcement parts (40, 70) each have a lower edge (69) which extends from the hinge connection (62) to the lower chord (34); and the lower edges (69) enclose an angle (68) with the plane (63) of the lower chord (34) that is smaller than the angle (67) which the transition piece (64) encloses with the plane (63) of the lower chord (34).
