Abstract
The invention relates to a large-scale manipulator, especially of concrete pumps. Said large-scale manipulator has a bending boom () which consists of at least three boom arms (to) and which is preferably configured as a concrete spreader boom. The arms of said boom are each pivotable to a limited extent about horizontal bending axes (to) which are parallel to each other, by means of a drive aggregate (to), respectively. A control device () for moving the boom with the help of actuating mechanisms that are allocated to the individual drive aggregates, and means for damping mechanical vibrations in the bending boom are also provided.
