Abstract

1. An excavator bucket (1), in particular a ditch-clearing shovel, for an excavator or the like machinery, attachment fixture (2) which incorporates a mounting (4) for connection to the boom of an item of construction machinery and a tilting device (5) which is located between the mounting (4) and the top (3) of the excavator bucket (1), the tilting device essentially comprising a pivot bearing (17) arranged with its pivot axis (16) in the longitudinal direction of the boom and a hydraulic cylinder arrangement connected between the top (3) of the excavator bucket (1) and the mounting (4) in a manner permitting articulation, the hydraulic cylinder arrangement being connected beneath the pivot bearing (17) by means of its end which is located close to the attachement fixture, characterized in that the top (3) of the excavator bucket (1) is designed as a hollow box girder (6) and the hydraulic cylinder arrangement comprises two hydraulic cylinders (23 and 24) which are arranged inside this hollow box girder (6), one on either side of the attachment fixture (2), the ends (27 and 28 respectively) closer to the attachment fixture being located between the pivot bearing (17) and the top (3) of the excavate bucket or, as the case may be, a lower flange (8) of the hollow box girder (6), and in the vertial plane of the boom axis (13) passing through the pivot bearing (17).
