The structure (SR) has a subset (S1) arranged to receive main wheels (3), and another subset (S2) arranged for receiving a mast (7). The former subset and the latter subset are joined by a connecting module i.e. clamp (12), in which an arm including a roller is arranged. The two subsets are arranged in a relative angular position for installation of a panel and a plate. The mast is vertically movable relative to the main wheels during installation of the panel or plate vertically by raising the former subset. |
