While changing the excavator attachments, the operator need to open the lock on the quick coupler by hand power with a spanner. Although it is by human manual, but it is like semi-auto, it is very convenient to change the attachments, comparing to remove all the connect pins on the arm .And especially, it doesn’t install any hydraulic hose or pipeline while install the quick coupler for the excavators.
