摘要:
It comprises two support assemblies (1) intended to be installed in the roof of a building, each of which has an anchoring system (35, 36, 39, 33, 34, 30) to the roof and a cantilevered arm (10) projecting perpendicular to the facade. The structure comprises a transversal guide (45) which is associated with the arms (10) of the two assemblies (1) and which is placed horizontally and parallel to the facade, and a carriage (46) which can be moved along said transversal guide (45), and from which a harness for an operator is hung who therefore can be moved sideways along the facade.
