The invention relates to a biogas plant comprising a fermenter vessel (1), in which an assembly support (2) is mounted, preferably vertically oriented, wherein an assembly (10), in particular a submersible motor driven stirrer, is retained by means of a height adjustment device (11) so as to be vertically adjustable on the assembly support (2). According to the invention the height adjustment device (11) is formed by a belt drive of which the traction means (13) is guided around at least two deflecting elements (15, 38) spaced apart from one another in the longitudinal direction of the assembly support, wherein at least one of the deflecting elements (15) can be driven in rotation by means of a driving device (19) and wherein the assembly (10) is coupled to the traction means (13) in such a way that when the deflecting element (15) is rotationally actuated in a first direction the assembly is raised and when the deflecting element (15) is rotationally actuated in a second, opposite direction, the assembly is lowered. |
