An excavator (1) comprises a tool holder (2) and a side-tipping bucket (3). The bucket is designed for side tipping around either of two junctures (11, 12) by a tip hydraulic (4) equipped with backlash. A locking hydraulic (5) centrally positioned on the fixture (2) features side piston rods, which are each joined to a flat-formed locking component (33, 34) for release of either juncture so that tipping around the opposing juncture can be executed by the tip hydraulic. The locking hydraulic (5) is part of the same pressure fluid perimeter (6) as the tip hydraulic (4) and is cross-connected to it.<IMAGE> |
