A support strut for mobile working machines, especially for mobile concrete pumps. The support strut (20) has a strut body (38) that can be pivoted around a vertical pivoting axis (32) on a chassis (10), a telescopic part (40), a dual-acting hydraulic cylinder (42) (38) and the telescopic part (40), in addition to a foot part (26) that. Both ends of the telescopic hydraulic cylinder (42) are fixed on fixing points (46, 50) in the area of the opposite ends of the body of the strut (39/8) and the telescopic part (40). The vertical pivoting axis (32) is defined by a divided bearing or journal location arranged at an axial distance (S) from the inboard fixing point (46) in the direction of the foot part on the body of the boom (38), said location being positioned in such a way that it transects the displacement axis (52) of the hydraulic cylinder (42) transversely. |
