Quick-change device
The invention relates to a quick-change device (10) having at least one locking bolt (26) and a motor drive which moves the locking bolt (26) into a locking position and an unlocking position, wherein the drive (16) has an energy connection (28a, 28b) and output means (34) interacting with the locking bolt (26), wherein the drive (16) comprises a rotary drive (30) having a motor and an output shaft (34), wherein the output shaft (34) is mechanically connected to the locking bolt (26), with the result that the locking bolt (26) is movable along an actuation axis. The invention is distinguished by the fact that the drive (16) has an attachment (20) for a shaft-hub connection, on which attachment a tool for manual actuation can be mounted, with the result that a manual actuation acts directly on the output shaft (34) and here the attachment (20) is arranged coaxially to a rotary connection (32a, 32b) of a gear shaft (32c, 32d).
