The invention relates to a patient support system comprising a frame mounted to a floor and an upright column movably mounted to the frame. lt comprises a holding brake device to hold the column in a set position, comprising a static component and a movable component, movable with the column in a reference plane. The holding brake device prevents the movable component to move in an activated condition and allows it to move in an inactivated condition, and comprises two first, static brake plates extending side by side from the static component in the reference plane, and two second movable brake plates extending from the movable component in the reference plane, overlapping the first brake plates. The first and second brake plates are arranged alternatingly. A pressure assembly applies a normal force to the brake plates to activate the brake device and releases said normal force to inactivate the brake device. |
