Abstract: The invention relates to a working tool for a piece of earth-moving machinery comprising a digging device (10) that is embodied as a bucket or scoop and delimits an accommodation space (24) for the material that is to be excavated, and a built-on device (12) which is disposed on the digging device (10), and is provided with an additional tool (14, 16, 17) that is pivotable towards the charging hole (43) of the accommodation space (24) by means of a swivel drive (36). In order to increase the number of possible uses, the swivel drive (36) encompasses a swivel shaft (42) which is located above the charging hole (43) and extends along more than half the width thereof while the additional tool (14, 16, 17) can be fixed to the swivel shaft (42) via connecting means (50).

Abstract: The invention relates to a tool for closing and separating pluggable quick acting closure couplings for hydraulic lines (12), comprising two engaging elements (18), each of which can be engaged with a coupling half (14, 16) of the quick acting closure coupling (10) and an actuation mechanism (20) enabling the plug-in movement of the coupling halves (14, 16) by performing a reciprocal relative movement of the engaging elements (18). In order to ensure reliable and simple operation, the actuation mechanism (20) has a linear guide (28) consisting of two guide parts (32, 34) that can be moved linearly one towards the other. The engaging elements (18) protrude crosswise with respect to the guide track (30) in each of the guide parts as projections.
