Embodiment 1

[0033] Example 1 ( figure 1 ) in such a way that a further support cylinder 6 with a support force acquisition device 10 is arranged as a central support centrally below the swivel bearing, said support cylinder being hydraulically adjusted corresponding to the desired support force and Thus receiving a vertical load.

[0034] Here, according to the invention, the operator can use the operating unit 7, 8 ( Figure 4 ) predetermines the desired state of preparation and the activation and boundary conditions of the central support or constraints for standard supports.

[0035] This information is transmitted to the crane control unit / CPU 9 and used to check and display the desired load capacity or to generate a possible new load capacity depending on the limited supporting force. Then, by confirming the displayed application conditions, this type of operation is activated and a corresponding supporting action is exerted hydraulically on the central support via the hydraulic pu...

Abstract

The present invention relates to a mobile working machine, especially a mobile crane, having an undercarriage (1) and a support device with support cylinders (2) to create the support base required for operation, a top carriage (3) mounted pivotably on the undercarriage (1), as well as an apparatus compatible with the type of the working machine, in particular outriggers (4) and a counterweight arrangement (5). One or more additional hydraulic supports (6) are arranged on the undercarriage (1) underneath or in the proximity of the pivot bearing of the top carriage (3), as well as a control unit (7, 8, 9), which monitors the loads of the support device (2) and controls and monitors the additional supports (6).

Description

technical field [0001] The present invention relates to a mobile working machine, in particular a mobile crane, which has an undercarriage and a supporting device with supporting cylinders for generating the supporting foundation required for operation, rotatably supported on said lower The devices on board the carriage and determining the type of the working machine are in particular the boom and the counterweight system. Background technique [0002] For mobile working machines, the increasing demands in terms of productivity, transport weight and partial limitation of the support forces occurring during operation represent a development challenge. [0003] Here, monitoring of standard support equipment is prior art. In DE 10 2008 021 627 A1, in addition to monitoring the variable support base geometry, the load of the support is also recorded and monitored. [0004] In DE 10110176 A1, for example, a measuring principle for monitoring the supporting force is disclosed. ...
