Quick-Change System for Changing Attachments on a Construction Machine
A quick-change system for changing attachments on a construction machine with a quick coupler arranged to be pivotable about a pivot axis orthogonal to the axis of rotation by means of a hydraulic slewing drive and rotatable about an axis of rotation on a connection part by means of a hydraulic rotary drive contains mounts and at least one locking element which can be actuated by means of a hydraulic drive to hold an attachment coupled to the quick coupler. The quick-change system includes a hydraulic control device, which contains a first control circuit to drive rotary drive and slewing drive, at least one additional control circuit to supply the attachment coupled to the quick coupler and a shuttle valve arrangement to expose the hydraulic drive to the higher pressures acting in the first or the at least one additional control circuit to activate the at least one locking element.
