Embodiment Construction

[0017] exist Figure 1a The truck-mounted concrete pump shown in to c comprises a chassis 10, a four-armed articulated rod 14 arranged on a substructure 12 fixed to the chassis and used as a support for the conveying pipeline, and two front supporting booms 16 ', 16" and two rear support arms 18', 18". In the illustrated embodiment, the articulated lever 14 has four lever arms 1 , 2 , 3 , 4 . Here, the first lever arm 1 is articulated with its one end 20 to a swivel head 24 which can be swiveled around a vertical axis 22 of the chassis 10 by controlling a rotary drive. Furthermore, the lever arms 1 , 2 , 3 , 4 can be swiveled about the horizontal articulation axes A, B, C, D relative to the swivel head 24 and respectively relative to an adjacent lever arm by controlling the associated articulation drive. The last lever arm 4 carries at its free end an end hose 26 which is connected to a conveying line, not shown.

[0018] The front support arms 16', 16" can be extended from ...

Abstract

The invention relates to an automatic concrete pump with an articulated mast (14) serving as a support for a supply line and with two forward and two backward support extensions (16',16'',18',18'') which can be supported on a base platform (32) and which can be lowered from a driving position into a support position, each with a telescopic support leg (30). According to the invention, each support extension comprises one inner support position near to the chassis, and at least one outer support position away from the chassis, which can be freely selected by forming defined support configurations (V,SL,SR,YL,YR,N) for the four support extensions. Further, a control device for the movement of the mast arm is provided which comprises a software program corresponding to the selected support configuration, which program limits the pivot angle of the first bending arm (1) about its bending axis (A) and an associated range of angular rotation of the rotatable head (24) about the vertical axis (22), according to the specification of the selected support configuration.

Description

technical field [0001] The invention relates to a motor-driven concrete pump, comprising: a chassis; an articulated rod which is arranged on a substructure fixed to the chassis and is used as a support for a conveying pipe and has at least three lever arms, the articulated rod The first lever arm is hinged with a free end on a swivel head that can rotate around a vertical axis of the chassis by controlling a rotary drive device, wherein each lever arm can be relative to the swivel head by a hinge drive device assigned to the control device and respectively relative to an adjacent lever arm swing around a horizontal articulation axis; there are also two front and two rear ones arranged on the substructure fixed to the chassis, which can be partially moved out from the driving position if necessary to a The support position is supported on the ground with a telescopic leg respectively so that the support cantilever that the chassis is lifted. Background technique [0002] The...
