The excavator scoop halves (17,18) are located around at least one shaft (16) adjoining the fixture (4,5) of the scoop to the machine arm (2,3) in such a way that they are pivotable independently of one another in relation to the fixture. For pivoting the front half (17), a primary power mechanism is provided and a secondary such mechanism is available for the rear half (18). In this way the scoop can be pivoted partly in its entirety with the two halves following one another, and partly with different movements for the two halves so that they can be opened in relation to one another. |
