Abstract (en)
[origin: CA3115426A1] The invention concerns a quick-change system for changing attachments on a construction machine with a quick changer (1) mounted to rotate in a drive housing (4) of a rotary device (3) and rotatable relative to drive housing (4) by a rotary drive (9, 10), and a rotary joint (6) arranged in the drive housing (4) with a stator (7) and a rotor (8) rotatable within stator (7) to supply a working fluid to the quick changer (1). In order to permit simple and stable fastening of the rotary joint, the stator (7) of the rotary joint (6) arranged within a through-opening (30) of the drive housing (4) is radially supported against the drive housing (4) above an upper end surface (38) and beneath the upper end surface (38) of a drive wheel (10) of the rotary drive (9, 10) arranged in drive housing (4).
