    摘要： The invention relates to a mobile work machine having a chassis (10) and with two front and two rear support brackets (20, 22). The support brackets can be displaced from a driving position close to the chassis into a support position by changing the base angles (α) thereof and/or can be telescoped by changing the lengths thereof between the end on the mounting side and that on the free end. In order to be able to automatically determine the support leg positions (Xc/Yc) in relation to the chassis (10), three transceiver units (S1/E1, S2/E2, S3/E3) related to the support legs are provided for transmitting and receiving run time or distance signals. Furthermore, a microprocessor-supported evaluation unit responding to the transmitted and received signals of the transceiver units arranged in pairs is provided, comprising a software routine for determining the support leg positions in a coordinate system (x/y) fixed to the chassis.

    摘要： 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.
