  • Said engaging by means of a vacuum preferably is carried out using a plurality of vacuum cups in case, due to circumstances, the vacuum is not or is not sufficiently applied. Furthermore, said engaging preferably is carried out on the tops of the corrugations of the corrugated plates. In general, less dirt which could lead to a reduced vacuum is present on the tops
  • a corrugated plate After having been lifted a corrugated plate will be brought into a horizontal position and will subsequently be moved for disposal thereof.
  • the lifting device for instance is a crane or reaching device with a boom.
  • An advantageous embodiment is characterized in that, after said lifting of the asbestos-containing corrugated plate, retaining elements located on at least two opposite longitudinal edges of the corrugated plate are positioned below the asbestos-containing corrugated plate, and the asbestos-containing corrugated plate is subsequently moved.
  • the asbestos-containing corrugated plate is accommodated in a formfitting manner in the device.
  • the engagement should fail, then the asbestos-containing corrugated plate will be held by the retaining elements and will not fall.
  • the retaining elements do not contact the corrugated plate, so that no asbestos particles are released.
  • An advantageous embodiment is characterized in that the frame is a first frame, and wherein the device comprises a second frame, wherein
  • the first element is suspended from the second frame by means of flexible elements, which flexible elements preferably have a defined maximum length.
  • flexible elements for instance are ropes, cables or chains.

  • a moveable device for the unscrewing a screw also the positioning thereof, at least in one direction (parallel to the roofs ridge), is facilitated control-wise, as the screws are generally only provided on tops of corrugated plate. That is to say, if the support elements are spaced at such a distance that there are five tops in between, then automatically there the five possible locations in a direction parallel to the corrugated plate and transverse to the support elements are known in that direction.
  • An advantageous embodiment is characterized in that after an asbestos-containing plate has been handed off, air is flushed out of the vacuum cups in order to remove any dirt that may have been sucked into the device via the vacuum cups.
  • the device may continue to operate reliably. In case of dirty roofs said flushing may occur prior to the removal of each plate.
  • the present invention relates to a device for the removing asbestos-containing corrugated plates from a roof of a building;
  • the device comprises a frame that is provided with at least one vacuum cup complementary to the top surface of an asbestos-containing corrugated plate, and the frame is provided with an auxiliary device, which is moveable relative to the frame, for unscrewing a screw.
  • Such a device is suitable for use with the method of the invention.
  • An advantageous embodiment is characterized in that the device comprises retaining elements for retaining a corrugated plate that is being held with the at least one vacuum cup of the device.
  • An advantageous embodiment is characterized in that the frame is a first frame, and wherein the device comprises a second frame, wherein
  • the full weight of the device rests on the corrugated plate, as the at least one component is held by the second frame which is not supported on the corrugated plate. Additionally, due to the reduced weight there is less chance of release of asbestos fibred due to damage.
  • An advantageous embodiment is characterized in that the first frame is connected to the second frame by means of flexible elements.
  • Such flexible elements for instance are ropes, cables or chains.
  • the flexible elements have a defined maximum length.
  • Fig. 1 schematically shows a roof 190 with supporting roof elements 191 (purlins 191) onto which asbestos-containing corrugated plates 192 have been attached which are to be removed.
  • a lifting device 195 here a reaching device
  • the lifting device 195 is provided, via the universal coupling piece 197, which device 100 according to the invention for the removal of corrugated plates 192.
