In the case of an agitator shaft (1) of a fermenter of a biogas plant, comprising agitator brackets (12), which are arranged on a shaft wall (10) and on which at least one agitating arm (2), comprising an agitating arm fastening portion (20) and a blade carrier (21) can be connected to the agitator brackets (12) by means of fastening two agitating arm fastening plates (200) of the agitating arm (2), it is intended to provide a method that achieves easier and quicker assembly of an agitator shaft and integration in a fermenter in situ, whereby a considerable cost saving in the setting up of a fermenter is achieved. This is achieved by cutting out fastening holes in the agitator brackets (12) and cutting out through-holes in the agitating arm fastening plates (200) in such a way that a plurality of retaining ring bolts (3) can be arranged so as to pass completely through the fastening holes and the through-holes and can be riveted therein. |
