CONCRETE-PUMP BOOM-ARM SEGMENT HAVING A VARIABLE SHEET-METAL THICKNESS IN THE LONGITUDINAL DIRECTION, AND METHOD FOR PRODUCING SUCH A CONCRETE-PUMP BOOM-ARM SEGMENT
The invention related to a concrete-pump boom-arm segment having an upper chord (33), a lower chord (34) and two lateral parts (35, 36) which connect the upper chord (33) and the lower chord (34). The boom-arm segment comprises a longitudinal connection (44) between two subregions (41, 42) of the boom-arm segment which adjoin one another in the longitudinal direction, wherein the longitudinal connection (44) extends over a chord portion (56, 66) and over a lateral part portion (53, 63). The lateral part portion (53, 63) is bent over with respect to the chord portion (56, 66) in the first subregion (41) and in the second subregion (42). The material thickness of the chord portion (56) is greater in the first subregion (41) than the material thickness of the chord portion (66) in the second subregion (42). The invention additionally relates to a method for producing such a boom-arm segment. Such a boom-arm segment is well suited for absorbing static and dynamic loads and can be produced in a cost-effective manner.
