| 摘要 |
<p>The heavy manipulator has a frame supporting a mast block which is rotatable about a vertical axis, provided with a handling mast having at least 3 relatively pivoted mast arms (23-27), operated via respective drive units (34-38) coupled to a control device, responding to remote-control commands and associated setting elements (68-76). At least one of the drive units or mast arms has a sensor (84,86) for detecting mechanical oscillation, coupled to an evaluation unit (82) providing a damping signal for the associated setting element. An independent claim for a method for damping mechanical oscillation of a heavy manipulator mast is also included.</p> |
