Abstract
The invention relates to an assembly for exchangeably fastening an add-on, for example an excavator shovel (), to an excavator boom (), whereby retaining bolts () spaced apart (A) in parallel are disposed on the excavator shovel (). Said retaining bolts () can be gripped by grippers () mounted on the excavator shovel () that can be hydraulically adjusted relative to each other. Said grippers () have open insertion openings () for the retaining bolts () in directions facing away from each other. The longitudinal axis () of the hydraulic drive () for adjusting the grippers (), the center axis () of the retaining bolts () and the center axis () of the insertion openings () on the grippers () are at least approximately arranged in one plane (). One gripper () is retained in parallel to the axis of the drive () in a guide () and can be linearly displaced. The parts of the hydraulic or pneumatic drive (), namely the cylinder () and the piston () are firmly linked with the grippers () (FIG.).
