Claim:
Device to transmit power from a power system ( 28 ) of a working machine ( 1 ) to one or more moving parts ( 25 , 26 ) of a tool ( 3 - 5 ) replaceably attachable to a first part of the working machine which is in the form of a beam, comprising a first element ( 7 ) arranged on the working machine and driven by its power system, a second element ( 11 ) movably coupled either directly or through at least one interconnecting component to the tool ( 3 - 5 ), and means ( 8 , 12 ) arranged to mechanically interconnect both of said elements ( 7 , 11 ) so that a displacement of the first element ( 7 ) via the working machine's power system brings about a movement of the second element ( 11 ) and the tool ( 3 - 5 ), wherein said means ( 8 , 12 ) for mechanical interconnection is arranged to automatically establish a mechanical interconnection of the first ( 7 ) and second ( 11 ) elements on attachment of the tool to the working machine's first part.
