A mounting system includes retaining bars which are structurally independent of one another, which can be optionally directly disconnected and directly connected relative to a support device through coupling devices that are activatable and deactivatable without tools. Using the mounting system, a method for charging a treatment device can also be carried out, with which the retaining bars are directly connected to a first support device, and following this, the retaining bars are directly connected to a second support device, in particular a rotor that is arranged in the treatment device. Following that, the mechanical connection between the first support device and the retaining bars is directly disconnected.
