Abstract: The invention relates to a method for setting up a mobile machine (1), particularly an automatic concrete pump, a mobile crane or a movable elevating work platform. With such a method, the subsurface (28) of a site is analyzed for the properties and/or load-bearing capacity thereof before the machine (10) is positioned there and/or oriented and supported by means of flarable supporting legs (20, 24) in set-up positions (VR, VL, HR, HL) suitable according to the determined subsurface properties and load-bearing capacity. In order to determine an optimized set-up position for the supporting legs (20, 24), geodata (38) of a geographic environment that includes the site is read via a computer in a data memory (44) using a layer of subsurface data (40) that defines the subsurface properties and load-bearing capacity.

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.

Abstract: A mobile implement, particularly an automatic concrete pump, with stability monitoring system includes an undercarriage supportable on a subsurface by two front and two rear outriggers. A respective measuring element is disposed in the telescoping support legs of the outriggers for determining the supporting force. Each support leg has an upper telescoping element connected to the associated outrigger at an upper connection point, and a support base displaceable relative to the upper element and supported on the subsurface at the lower end thereof at a lower connection point. The measuring element is disposed either directly at the upper connection point between the outrigger and the upper telescoping element, or in the region of the lower connection point between the lower telescoping element and the support base.

Abstract: The invention relates to a moveable working device, particularly an auto concrete pump, comprising an undercarriage (10) provided with two front and two rear supporting extension arms (22,24) which can be extended from a travel position into at least one support position, which can be supported on a foundation (36) and which are respectively provided with a supporting leg (28), also provided with a respective measuring member (38) for determining the support load acting upon the supporting legs (28). If the telescopic supporting legs (28) with the telescopic member (30) fixed to the extension arm are coupled to a support leg casing by means of a coupling bolt (32), it is possible to configure the coupling bolt as a measuring member (38) in order to determine the support load, using particularly simple means. The measuring members can be incorporated into a stability monitoring device comprising a computer-assisted evaluation electronics system (68,74).

Abstract: A working boom with a rotating head on a frame, which rotates about a vertical axis, and boom arms that are each either pivotable or slideable by the use of a drive unit. The working boom includes a control device that controls boom movement with the aid of actuators assigned to each drive unit. Path or angular sensors are assigned to the boom arms, bending axes, vertical axis and/or or drive units. At least one of the drive units includes a hydraulic cylinder with a ground end and a rod-side end. A force or pressure sensor is disposed on the ground end or rod-side end of the hydraulic cylinder. A data storage device receives a pre-set data field of pressure and/or force limit values in connection with a respective path or measurement value assigned to the boom arms, the pre-set data field being analytical or in tabular form.

Abstract: The invention relates to a mobile working machine, particularly a mobile concrete pump, comprising a device for monitoring the stability thereof when in operation. The working machine comprises a chassis (10), which contains a supporting structure with two front and two rear support struts (20). The support struts can be extended out of a transporting position and into at least one supporting position and each can be supported on a surface (28) by a telescopic supporting jack or foot (26). The working machine additionally comprises a working boom (14), which can be extended out of a transporting position and into working positions that project beyond the chassis, which can rotate about a vertical axis that is fixed with regard to the chassis, and which is preferably provided in the form of a concrete distributing boom. Measuring devices for determining the respective supporting load are arranged in the area of the supporting foot and their output signals are sent to a stability monitoring device.
