Abstract (en)
[origin: EP0294843A1] An excavator (2) has a main boom (12) as well as a front boom (24) and an extension arm (26) with a bucket (32) fastened thereto. Arranged between the main boom (12) and the front boom (24) is a pivot joint (14) which has a perpendicular pivoting axis (16) at a defined working position of the main boom (12). The front boom (24) can be pivoted relative to the main boom (12) by the pivot joint (14) so that trenching work parallel to the longitudinal axis of the excavator (2) is also possible outside the track width of the excavator (2).
