  • the tilting frame 2 is preferably formed in cross-section L-shaped.
  • the tilting frame 2 consequently has a long tilting frame surface 3 and a short tilting frame surface 4, wherein the Kipprahmen inhabit 3, 4 each need not be formed flat, but from a plurality of parallel steel profiles 5 (in FIG. 5 the steel profiles of the tilting frame surface 4) are visible.
  • the fire test furnace 1 comprises at least one sliding or mounting rail 6, on which the tilting frame 2 with the Kipprahmen importance 4 is formed directly or indirectly resting.
  • the tilting frame 2 can be displaced by means of at least one first piston-cylinder unit 10 on the slide or support rail 6 along the slide or support rail 6.

  • the tilting frame 2 is guided with rollers 18 in the slide rail 6, wherein preferably the slide rail 6 is removed from the lower tilting frame surface 4, for example by a roller cross member 19, which is arranged below the Kipprahmen appearance 4.
  • FIG. 6 are two slide rails 6, starting from a cross member 19, depending on a roller 18 laterally engages the rail 6, wherein additionally from the outside, from the bearings 13 ago, rollers 20 also engage in the rail 6, so that the tilting device on both sides in the slide rails 6 is guided.
  • FIG. 7 has the Kipprahmen phenomenon 4 below and above the rails 6 each have a support means 21 for rollers 22, wherein the rollers 22 are preferably arranged in the region of a free from the bearing 13 remote end of the Kipprahmenthesis 4 and roll on the rail 6 on the upper side, so that the tilting frame 2 on the rails 6 is easily moved.
  • the basic principle is based on a simultaneous longitudinal displacement by elongation of the piston-cylinder unit 10 along the slide or support rail 6 by means of the piston-cylinder unit 14 a defined and controlled tilting of the tilting frame 2 and thus arranged on the tilting frame 2 or fixed actual oven space 25 (in FIG. 1 dashed lines) perform.
