• At least the second and each subsequent level 20.2, 20.3 of the mobile scaffold 10 is/are secured, towards their respective long sides or outer sides 73.1, 73.2 of the mobile scaffold 10, with two side protection double railings 11 each in such a way that a person standing on the scaffold deck 17.1, 17.3 to be secured or on the scaffold decks 17.1, 17.3 to be secured of these levels 20.2, 20.3 is protected from falling.
• the respective top strut 35 of the respective side protection double railing 11 forms a hip or back protection railing or a handrail.
• the side protection double railings 11 of the respective levels 20.2, 20.3, or levels of the mobile scaffold 10 are arranged laterally next to one another at a horizontal side protection double railing spacing 74 at essentially the same height.
• all side protection double railings 11 are of the same design.
• the or each side protection double railing 11 extends along a side protection double railing longitudinal axis 46 of the side protection double railing 11.
• the or each side protection double railing 11 is designed mirror-symmetrically to a side protection double railing longitudinal central symmetry plane 47.
• the side protection double railing longitudinal central symmetry plane (47) is formed perpendicular to the side protection double railing longitudinal axis 46 and/or perpendicular to the upper strut longitudinal axis 30 and/or perpendicular to the lower strut central part longitudinal axis 40 and can contain the lower strut center 54.
• further securing means here in the form of toe boards 78.1, 78.2, are preferably provided. These are arranged vertically directly adjacent to the uppermost scaffold deck 17.3 provided there and extend between adjacent vertical struts 15.1, 15.2 of the ladders 13.1, 13.2 delimiting the uppermost level 20.3 or level.
• Two immediately adjacent or adjacent/abutting toe boards 78.1, 78.2 are arranged perpendicular to each other.
