The device is for the control of movement around one or more pivoting centers in a work machine (2) formed as a grip component for securing wire, which is pivotably supported by a crane arm (1). The device is connected with the crane arm via articulated components (5), which form the pivoting centers. To these components are connected components (11) which momentarily render them rigid between the crane arm and the device. In order effectively to control the work machine pivot movements, the axis lines formed along the pivot center have two spaced apart connecting points (4,4') which extend through opposite openings (7,8) in the crane arm and the grip component. At least one of the connecting axes has a first part (15) which is not rotatably arranged relatively to the one opening and a second part (17) which is rotatably arranged relatively to the second opening. The rigidity component is effective between the connecting axes and the grip component or the crane arm, which via its opening is pivotably relatively to the bearing axis. |
