Concrete pump with distributing boom
The invention relates to a work device with a stationary or movable frame (10, 10', 10'') which has a substructure (14, 14', 14'') fixed to the frame, a rotating head (32) which can be rotated about a vertical rotational axis (30) on a bearing block (35) of the substructure by means of a drive mechanism (33), and an extension arm (16). The extension arm (16) is mounted on a bearing point (36) of the rotating head (32) in a pivotal manner about a horizontal pivot axis (38). A hydraulic cylinder piston unit (40) is further provided, the ends of which (42, 44), said ends being fixed to the cylinder and to the piston rod, are hinged to hinge points (46, 48) on the extension-arm side and on the rotating-head side with a horizontal hinge axis. The invention is characterized in that the rotating head (32) has a base section (50) arranged on the bearing block (32) and an adapter piece (52) comprising the bearing point (36) for the extension arm (16) and the hinge point (48) on the rotating-head side for the cylinder piston unit (40). The base section (50) and the adapter piece (52) can be coupled to each other in a removable manner via a separating point (54).
