Abstract: A spraying arm assembly for a trolley (1) for holding objects to be cleaned, which trolley can be introduced into the spraying compartment of a cleaning machine for utensils placed on individual tiered racks: rotatable spraying arms (3) are assigned individually to each rack. The arms have outlet openings (31, 32, 33), from which spraying-liquid jets can be directed onto the utensils. Individual spraying arms (3) are attached one above the other to a central support post (2), which is rotatably supported. The spraying liquid is introduced into an interior space of the support post (2), and interior spaces of the individual spraying arms are connected to the interior space of the support post (2).
