摘要 PCT No. PCT/SE92/00586 Sec. 371 Date Mar. 8, 1994 Sec. 102(e) Date Mar. 8, 1994 PCT Filed Aug. 25, 1992 PCT Pub. No. WO94/02184 PCT Pub. Date Feb. 3, 1994.In the process of soil excavating work or like work with the use of excavators and loaders, it is becoming more usual to use different hydraulically functioning implements. It is often necessary to exchange these implements several times during a working day, necessitating the driver to connect and disconnect the hydraulic hoses involved manually, which can be a time-consuming task and one which is encumbered with the risk of oil spilling from the hoses and generally soiling the clothing of the workman involved, tools and the surrounding ground. The hydraulic hoses that hang loosely from the removed implement are easily damaged and foreign particles and contaminating particles are able to enter the unprotected and to simplify connection of hydraulic hose couplings (8, 9) to different implements having hydraulic functions when using an implement quick-coupling arrangement (1) fitted to an excavator, digger or like machine, the couplings have been positioned in a protected place in the quick-coupling arrangement (1) itself and the connection is arrangement so the when the movable part (6) of the quick-coupling moves in an implement coupling or implement uncoupling direction, the hydraulic couplings which are operative in powering movement of the implement will be connected or disconnected at the same time.
