WORKING DEVICE WITH STATIONARY MAST AND ROTARY HEAD
The invention relates to a working device with a base (10) designed as a stationary support column, a motor-driven rotary head (32) and a stack of arms (34) consisting of several mast arms (1, 2, 3, 4) which can be moved with respect to each other in pairs, by means of articulated or sliding joints, supporting a concrete transport line. Said stack of arms (34) is articulated on the rotary head (32) about a horizontal rotational axis by means of a first mast arm (1). The working device also comprises a control mechanism (90) which can be actuated by a control element or a radio path and which is arranged in a control box (92), and a hydraulic assembly (84) comprising an oil tank (86) and a motor-driven hydraulic pump (88) for controlling working groups for moving the rotary head and mast arm. A working platform (78) fixed with respect to the frame is arranged in the region of the bearing block (35) for emergency operations. In order to ensure that the components required for actuating the stack of arms (34) are not in the way of the engine in the event of an emergency operation, the oil tank (86) of the hydraulic assembly (84) is arranged on the rotary head (32) and comprises a contour which is geometrically adapted to the rotary head (32), defining a window opening (98) for the passage of a ballast boom (116, 134) which is detachably arranged on the rotary head (32). The oil tank (86) also comprises a holder (102) for receiving the control cabinet (92) which can pivot about at least 90 DEG with respect to the window opening (98) about an axis (100) parallel to the rotational axis (30) of the rotary head (32).
