QUICK-CHANGE SYSTEM FOR CHANGING ATTACHMENTS ON A CONSTRUCTION MACHINE
The invention relates to 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 (12) and rotatable about an axis of rotation on a connection part by means of a hydraulic rotary drive (9), which contains mounts and at least one locking element which can be actuated by means of a hydraulic drive (27) to hold an attachment (46) coupled to the quick coupler (1). The quick-change system is characterized by a hydraulic control device (44), which contains a first control circuit (47) to drive rotary drive (9) and slewing drive (12), at least one additional control circuit (61) to supply the attachment (46) coupled to quick coupler (1) and a shuttle valve arrangement (64) to expose the hydraulic drive (27) to the higher pressures acting in the first or the at least one additional control circuit (47, 61) to activate the at least one locking element (26).
