Abstract

The invention relates to a quick-change device with a hydraulic coupling for media on a building implement, comprised of a quick-changer (30), which is fastened to the implement and which can be locked together with an adapter plate (12) fastened to the tool, and comprised of a device for aligning interacting parts between the building implement and the tool. A respective coupling valve (1, 3) is mounted on the quick-changer (30) and on the adapter plate (12), at least one coupling valve (1, 3) being mounted in a floating manner. According to the invention, a device is provided for aligning for the locking motion between the quick-changer (30) and the adapter plate (12) (primary alignment), and a separate device is provided for aligning the hydraulic coupling with regard to the quick-changer (30) and/or to the adapter plate (12) during operation (secondary alignment).
