  • a spreading head 9 is rigidly attached, which is located in this way at an optimally set, constant distance from the jacket surface 3 to be treated and moves back and forth on it at a set distance during the operation of the device .
  • the spreading head 9 can be both the nozzle of a sand spreading device and the spreading head of a paint spraying device. If necessary, several spreading heads 9 can also be attached to the carriage 8.
  • a limit switch 10 which is actuated by the carriage 8 itself in such a way that the signal coming from the limit switch 10 switches the transmission 7 of the carriage 8 in the opposite direction.
  • the speed of the electrically driven transmission 7 is continuously adjustable, the speed of the back and forth movement of the Wagens 8 can be set to an optimal value.
  • the function of the limit switches 10 can be combined with the fact that in the one end position not only the direction of rotation of the gear 7 is changed, but at the same time the gear 5 is moved downwards by one pitch with the help of the gear 4.
  • the size of the speed of movement of the carriage 8 and the vertical movement of the mobile scaffold 5 is to be determined on the basis of experience based on the knowledge of the nozzle available for the sand spreading device or the spreading head of the paint spraying device.
  • the spreading head 9 of a sand spreading device or a paint spraying device is rigidly attached to the carriage 8 at an optimal distance from the surface to be treated. Then the scaffolding 5, on which the rail track 6 or the carriage 8 is arranged, is raised by means of the gear 4 to the upper end point, so that the spreading head 9, in the first step the nozzle of the

  • the spreading head 9 of the sand spreading device expediently moves about 10 m to the right with the help of the carriage 8, then back to the left in the same lane after the actuation of the limit switch 10 until the left limit switch 10 is reached, after which the mobile scaffold 5 with the aid of the Gear 4 is moved down to the desired extent.
  • the Stepless adjustment of the speed of the carriage 8 can ensure that the degree of cleaning of the surface or the thickness of the applied layer correspond to the prescribed values when spreading the stand and when applying the color protective layer.
  • the downward movement can be both automatic and manual
  • the surface is dedusted, if necessary passivated, after which some primer color layers and finally two top color layers are applied as prescribed.
  • the frame 2 When a section is finished, the frame 2 is moved on the wheels 1 rolling about 10 m to the right, fixed and the work is continued as described above. With each change, care must be taken to ensure that the two end points of the guideway, optionally the rail track 6, are at the same distance from the lateral surface 3 of the container.
  • the surface is also dusted in strips, then provided with two layers of primer paint. If the primer paint layer is already dry (dust dry), the device is switched to the next 10 m section, the surface is cleaned, dusted, provided with primer paint layers and this process is repeated until the entire container is provided with a primer paint layer.
  • the device is reset to the first 10 m section and the opaque layers are applied one after the other, and this is repeated in the second, third and further sections.
  • This work can be completed with the help of a compressor with a capacity of 2000 m 3 / h and a pressure of 10 bar with two working shifts per day within a month if a fast drying dye is used.
