Abstract (en)
[origin: US2003038466A1] The invention relates to a support boom 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) that can be telescopically displaced relative to the body of the strut, a dual-acting hydraulic cylinder (42) that passes through the body of the strut (38) and the telescopic part (40), in addition to a foot part (26) that can be displaced vertically and is arranged on the outboard end of the telescopic part (40). 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). In order to reduce the required space in the transport position and during deployment of the support boom while ensuring stable support, 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.
