Claim 14:
15. An arrangement for releasing a coupling connection of a hydraulic quick coupler, comprising:
a hydraulic coupling for receiving a hydraulic plug, the hydraulic coupling including a coupler housing and a coupler cartridge displaceably mounted therein such that when the hydraulic plug is pushed in, the coupler cartridge adopts an operating position locking the hydraulic coupling;
at least one electrical actuator, the coupler cartridge being urged thereby into a transfer position which is overcome when the hydraulic plug is pushed in; and
a controller configured to instigate an external force for actuating the coupler cartridge in accordance with a triggering command indicating an imminent mechanical overload of the coupling connection;
wherein the coupler cartridge is movable via the electrical actuator from the operating position to an ejection position for releasing the hydraulic plug.
