Person e.g. worker, protecting device for building, has parallelepiped frame laid on lift of enterprise supporting grid maintained by telescopic horizontal rods having unfolding positions, where rods serve for gripping end of grillage

摘要

The device has a parallelepiped frame (1) laid on a lift of an enterprise (2) supporting a grid (3) maintained by two telescopic horizontal rods (4, 5) having two unfolding positions, where the frame has a minimum height of 2 meters. The horizontal rods are connected with respect to each other, and are oriented towards the air space. The horizontal rods serve for gripping an end of a grillage of height equal to the height of the frame and of variable width.
