  • the articulated support 17 can be adjusted in its height relative to the substructure 16 by means of a lifting device 18 in order to install between the substructure and the articulated support one or more layers 19 a - h of spacer elements 20 in order to be able to adjust the vertical position of the articulated support 17 and thus the reversing station 13 which is attached for articulated movement to same.
  • the lifting device 18 consists essentially of four lifting cylinders 21 in total which are mounted in the corner areas of a roughly rectangular base plate 22 of the articulated support 17.
  • the four lifting cylinders 21 are combined into two lifting cylinder pairs A, B so that the two lifting cylinders of each one lifting cylinder pair lie diagonally opposite one another.
  • the lifting cylinders 21 of each lifting cylinder pair A and B respectively can be actuated in pairs, for example, the lifting cylinder in the left front corner and the lifting cylinder in the right rear corner are actuated simultaneously or the lifting cylinder in the left rear corner and the lifting cylinder in the right front corner are actuated
  • the spacer elements 20, to which the articulated support 17 can be mounted off-set by the different layers 19 relative to the substructure 16, consist of identically configured distance members 23 which can be locked with positive engagement to one another and to the substructure 16 as well as to the articulated support 17.
  • a total of six distance members are provided whose length and width are each dimensioned so that the sum of the length of one distance member and its width is adapted (matched) to the width of the support structure 14 and the length of two distance members plus the width of one distance member is adapted to the length of the support structure 14 (Fig. 4).
  • the distance members are formed in cross-section as roughly I-shaped profiled strips which can be seen particularly clearly in Figs. 5 to 7.
  • bolt pins 24 which in the installed state fit in adapted bolt sockets 25 in further distance members or in the substructure 16 mounted underneath.
  • the bolt pins 24 are formed as tubular sleeves which are inserted between the arm 26 at the top and the arm 27 at the bottom of the distance members 23 as part of the web 28 connecting these together, wherein they project down a little further over the lower arm 27, as can be best seen from Fig. 6.
  • the bolt sockets 25 are provided on the upper arm 26 not only on the right and left in the end areas, but additional bolt sockets 25' are located off-set inwards about an amount which is adapted to the width of one distance member.
  • the distance members In order to be able to fixedly connect the distance members to one another and to the upper articulated support or the lower substructure, in the case of the first embodiment of the distance members, as shown in Figs. 5 and 6, several cylinder screws 29 are provided each time which are pushed through bores 30 provided in the upper and lower arms 26, 27 and are screwed to securing nuts 31.
  • the securing elements are formed as bolt pins 33 provided with an oblong head 32 wherein the oblong heads 32 can be pushed through oblong holes 34 arranged on the relevant distance members above or on the articulated support and can be turned by one quarter turn to produce a positive locking connection.
  • the bolt pins are provided with a threaded section 35 on which a locking nut 36 can be screwed.
  • the locking nuts are designed as hammer nuts with four hammer noses 37 arranged spaced out round the perimeter to which a tool such as a hammer or chisel can be fitted in order to be able to particularly tighten up the locking nuts and also to enable subsequent release by means of the hammer and/or chisel.
  • the distance members of two superposed layers 19 a-h to be arranged off-set relative to one another, namely by an amount which corresponds to the width of the distance members.
  • the articulated support 17 is raised further up so that then two distance members can be placed in pairs, thus diagonally opposite one another underneath the lifting cylinder of the other lifting cylinder pair B, A, which is not active in this lifting process, wherein preferably a locking of these two distance elements with the layer underneath immediately takes place.
  • the cylinders of the second cylinder pair are then loaded and extend out downwards whereby they fit into bolt sockets at the ends of the distance members installed immediately before and during subsequent inward movement of the piston rods of the cylinders of the first lifting cylinder pair take over their function and thus hold the articulated support 17 furthermore in a position raised up so that now the remaining four distance members can be installed and locked with the layer underneath.
  • the lifting cylinders of the second cylinder pair then move in again and hereby set the articulated support down on the newly installed spacer element layer whereupon the locking then takes place between the articulated support and the new layer.
  • a height of the articulated support 17 may be supported solely at two diagonally opposite corner areas of the articulated support 17 by means of a pair 21 A, 21 B of lifting cylinders 21. Then, if increasing a height, a pair of distance members 23 is placed underneath the other two diagonally opposite corner areas of the articulated support 17 at which the articulated support 17 is not supported.
  • the supporting of the articulated support 17 is translocated from the two diagonally opposite corner areas of the articulated support 17 to the other two diagonally opposite corner areas of the articulated support 17 by means of an other pair 21 A, 21 B of lifting cylinders 21.
  • the articulated support 17 is now supported on the placed pair of distance members 23. Underneath the two diagonally opposite corner areas of the articulated support 17 at which the articulated support 17 is not supported, a further pair of distance members 23 is placed.
  • the articulated support 17 can be supported on a new layer of distance members 23.
  • a pair of distance members 23 is removed from underneath the other two diagonally opposite corner areas of the articulated support 17 at which the articulated support 17 is not supported. Then supporting is translocated to the other two diagonally opposite corner areas of the articulated support 17, and a further pair of distance members 23 can be placed underneath the two diagonally opposite corner areas of the articulated support 17 at which the articulated support 17 is not supported. Thus, the articulated support 17 can be lowered to be supported on a lower layer of distance members 23.
  • the distance members which are all formed the same can be used in all possible installation positions which makes their handling much easier. Since the distance members of one layer are each off-set by an amount corresponding to their width relative to the distance members of the layer lying below or above same, a very stable construction is obtained which makes it possible to build up the support structure 14 even to a level which for reasons of stability was not reached with the hitherto known constructions.
  • the present disclosure discloses a lifting device that has two pairs of lifting cylinders whose lifting cylinders are arranged diagonally opposite one another in corner areas of the articulated support and can be actuated in pairs and in that as a spacer element for a lifting stage at least four distance members are provided of which two in each case can be placed in pairs underneath the lifting cylinders of the pair of lifting cylinders which are not loaded during a lifting process.
  • the lifting cylinders are fixedly attached before each lifting process on the structural element (articulated support or distance member) arranged underneath same, since the active lifting forces act practically exclusively vertically and are reliably dissipated downwards even without any solid connection.
  • the distance members and/or the substructure are provided in their areas located underneath the lifting cylinders with guide recesses or bolt sockets into which the extending piston rods of the lifting cylinders positively engage by their relevant end area and are supported on a stop face located preferably a little underneath the top side of the distance members or substructure.
  • the distance members may be formed identical so that each distance member can be inserted at any point in the support structure. It may be also advantageous if the distance members can be locked positively with one another and/or with the substructure and the articulated support, which can be implemented for example in that the distance members may be provided with downwardly or upwardly projecting bolt pins which in the installed state fit into conforming bolt sockets in further distance members arranged below or above same or in the substructure or in the articulated support.
  • the distance members can be locked relative to one another and/or to the substructure or the articulated support by means of securing elements such as by way of example safety screw connections or bolt wedges.
  • the securing elements may be designed as bolt pins provided with an oblong head wherein the oblong heads can be pushed through oblong holes arranged on the distance members and/or the substructure or articulated support, and can then be turned about roughly 90° for a positive locking engagement.
  • the arrangement can thereby be produced so that the bolt pin may be provided with a threaded section on which a locking nut can be screwed.
  • This design may enable a very rapid assembly of the securing elements to connect the distance members which are arranged one above the other to one another and to the substructure or the articulated support, since the locking nut can hereby be already screwed on the threaded section when the bolt pin is pushed with its oblong head through two mutually aligned oblong holes of the structural parts which lie one above the other and which are to be locked to one another.
  • the bolt element need then only be turned by a quarter turn so that the areas of the oblong head projecting at the sides fit behind the narrow sides of the relevant oblong hole.
  • the locking nut which is already screwed onto the threaded section can then be tightened up firmly.
  • the securing elements or their bolt pins can be screwed to locking nuts provided as hammer nuts for securing the distance members to one another or to the substructure and the articulated support.
  • the distance members of two superposed spacer element layers are/become arranged off-set relative to one another. This then produces a very stable structure for the support structure even with very great construction heights. It may be possible that for each lifting stage six distance members are/become provided wherein the width to length ratio of the sides of the support structure then amounts to about 2: 1.
  • the distance members may be preferably designed as profiled strips shaped with a double T or I-shaped cross-section.
