Abstract
The invention relates to an apparatus for sandblasting surfaces of objects of large surface area with a granular agent. The apparatus has a bucket (2) which can be moved parallel to the surface of the object, in which a sandblast aimed against the surface of the object (30) can be produced, and in which sandblasting grits rebounding from the work surface together with the removed dirt particles are caught and carried away. The apparatus is provided with a sealed cabin (1) for carrying an operator (2), which is equipped with viewing windows, and which forms with the sandblasting chamber (5) a mobile working unit (4). The bucket (3) is disposed on the outside of the cabin (1) for movement relative to the cabin surface.
