In order to quickly and easily provide a coupling of a drive fluid to a hydraulic cylinder of an accessory of an excavator, a part articulately connected with a dipper arm and a dipper ladle link of the excavator is also provided with one or more hydraulic couplings of a female type. The accessory to be coupled to the part is provided with the corresponding hydraulic couplings of a male type, so that on connection to the part the accessory after fixing, rotating and locking is also connected to a drive fluid. The hydraulic couplings are kept together by the accessory having been connected to the Joint means of the excavator. When the accessory is disconnected and removed, the hydraulic connections will also be interrupted.

Abstract

In order to quickly and easily provide a coupling of a drive fluid to a hydraulic cylinder of an accessory of an excavator, a part articulately connected with a dipper arm and a dipper ladle link of the excavator is also provided with one or more hydraulic couplings of a female type. The accessory to be coupled to the part is provided with the corresponding hydraulic couplings of a male type, so that on connection to the part the accessory after fixing, rotating and locking is also connected to a drive fluid. The hydraulic couplings are kept together by the accessory having been connected to the Joint means of the excavator. When the accessory is disconnected and removed, the hydraulic connections will also be interrupted.
