The disclosure relates to a working machine, which comprises a first boom part, a second boom part detachably connectable to the first boom part, a first and a second fluid-guiding line and a coupling device for reversibly coupling the first and second lines. The first line is arranged on the first boom part and the second line is arranged on the second boom part. The coupling device comprises a first coupling part connected to the first line in a fluid-conducting manner, a second coupling part connected to the second line in a fluid-conducting manner and connected to the second boom part, and a pivot part connected to the first boom part, which can be pivoted about a pivot axis. By pivoting the pivot part about the pivot axis, the two coupling parts can be coupled in a fluid-conducting manner. According to the disclosure, the working machine comprises a locking mechanism.
Working machine having a first boom part, a second boom part detachably connectable to the first boom part, at least one first fluid-conducting line arranged on the first boom part, at least one second fluid-conducting line arranged on the second boom part and a coupling device for reversibly coupling the first and second lines, wherein the coupling device comprises a first coupling part connected to the at least one first line, a second coupling part connected to the at least one second line and connected to the second boom part, and a pivot part connected to the first boom part and pivotable about a pivot axis, wherein the first coupling part can be coupled to the second coupling part in a fluid-conducting manner by pivoting the pivot part,
