A creep-speed drive (10) is connected to a shaft (8) of a main drive (2) by means of an overrunning clutch (12). The creep-speed drive has a driving wheel (20) which is mounted in freely rotatable fashion on the shaft (8) and which contains at least one driver (24). The latter projects into the path of motion of at least one catch (26), which is arranged on a carrier (28) rigidly connected to the shaft (8). When the main drive (2) is stationary, the catch (26) is in the driving position. When the main drive (2) is running, however, the catch is moved into the release position by the centrifugal force. <IMAGE>
