<p>The apparatus has a platform (12) vertically moving on a wagon (5) and lifted by a hydraulic jack. A slab support surmounting the platform supports a slab to be fixed on a ceiling. A table moving vertically between the platform and the slab support is lifted by another hydraulic jack. Tools held in rows and columns on the table are turned between two positions by a pneumatic rotation plate (26) fixed at an end of a shaft (25). The tools includes a boring machine to pierce a hole in a ceiling across the slab to be fixed and a pneumatic hammer to plant a pin inside the hole realized by the boring machine. The pneumatic rotation plate turns the tools towards a position in which wires of boring machines are directed towards the ceiling and the hammers are juggled off and the other position in which the hammers are supplied for planting the pins and the boring machines are juggled off. The hydraulic jacks and the rotation plates are controlled by respective control levers.</p> |
