Abstract

The working device (10) has a hydraulic excavator (1) with multipart arms (8). A rotary carrier is attachable at the free end of the final arm (9) with a holder (18) for an upper side of grip arm shells (19,20) of grip arm. The grip arm is convertible to a spoon by mechanical blocking of the closed grip arm shells at the holder. The grip arm shells are stored in drag axis (11,12) at the holder and are coupled mechanically with one another.
