Definitions

  • the invention relates to a scissor lift table, in particular for lifting or lowering loaded pallets or the like. According to the preamble of claim 1.
  • the invention has for its object to provide a scissor lift table, in particular for lifting or lowering pallets, which allows stable support even high loads while maintaining the drive-in space with little technical effort.
  • the design of the table platform optimizes its wing from the point of view of increased torsional stiffness and even force input into the areas of the edge profile strip above the scissor arms, whereby the support plate creates a composite construction of the table platform, in the drive-in space of which a pallet truck can be positioned in the transport position and then the pallet can advantageously be placed both on the edge profile strip and on the support member in such a way that a stable support of the pallet can be achieved during the lifting movement of the scissor lift table.
  • the table platform can be adapted to changing operating conditions with little effort by changing the area of the support links so that a sufficiently secure grip is formed for the pallet, even high supporting forces can be stably distributed as surface load over the support plate and thus overloading the scissor lift table and the pallets can be avoided.
  • FIG. 1 is a perspective view of a scissor lift table designated as 1, which is designed as a flat lift table, scissor arms 6, 7 or 7, which are arranged along the longitudinal edges and are connected in pairs in cross joints 4,5, between a bottom frame 2 and an upper table platform 3. 8.9 are provided.
  • the table platform 3 can be moved from the illustrated upper lifting position into a lowering position (not shown) close to the ground (not shown) by means of an arbitrarily switchable lifting movement on the Table platform 3 load, such as a pallet, is accordingly accessible in different positions.
  • the table platform 3 for loading for example with a transport pallet
  • the table platform 3 for loading can be driven on by a pallet truck in the area of a drive-in space 13, so that the transport pallet (not shown) can then be supported in the area of an edge profile strip 14 which defines the drive-in space 13 in a U-shape and at the same time an additional support area for the transport pallet is formed with support members 15, 15 '.
  • the edge profile strip 14 is connected in the plane of its free lower edge regions 16, 18 (FIG. 3) to a flat support plate 17 spanning the entry space 13, on which (according to the design in FIG. 5) at least one with respective upper edges 21 , 22 of the edge profile strip 14 is provided with a supporting member 15 '' which runs in the same plane.
  • FIG. 2 illustrates that the table platform 3 in the region of the support plate 17 is expediently provided with two support members 15, 15 'running in a longitudinal center plane 23, which are spaced apart in a central longitudinal plane 19 in such a way that a uniform loading of the support plate 17 is achieved is.
  • the support members 15, 15 ' are each designed as a profile part (FIG. 3) having an upper pressure introduction surface 24 in cross section and respective support struts 25, 26 directed towards the support plate 17.
  • FIGS. 1 and 5 illustrate that a support member 15, 15 'or 15''is provided in each case a cylinder body welded to the support plate 17 in a suitable embodiment and a base plate 27 as the pressure introduction surface 24.
  • the support member 15, 15 'in each case by forming the support plate 17 as a one-piece molded part (not shown) or to provide the base plate 27 with a rectangular contour, on the underside of which only a support strut is provided toward the support plate 17.
  • the sectional view according to FIG. 4 clarifies that the support plate 17 can be welded in an expedient embodiment in each case on the edge side to the inner lower edge regions 16, 18 of the edge profile strip 14, a different connection form also being conceivable here.
  • Fig. 4 shows a cross section of the table platform 3 that a front region 28 (Fig. 3) of the support plate 17 extends between respective inner side legs 30,31 of the two longitudinal struts 32,33 forming the U-shaped edge profile strip 14, on the underside thereof the respective scissor arm pairs 6.7 and 8.9 are supported (FIG. 1).
  • the support plate 17 In a rear area 34, the support plate 17 is extended so far that it engages under the edge profile bar 14 in the area of the cross strut 35 (FIG. 3) and thus a stable connection of the support plate 17 to the edge profile bar 14 is achieved.
  • the stability of the support in the area of the support members 15, 15 'for the load can also be achieved with the support plate 17 according to the invention if it has a length dimension (not shown) that is shorter than the longitudinal struts 32, 33 of the U-shaped edge profile strip 14 and is set back in the region of a front edge edge 36.
  • the second embodiment of the table platform 3 illustrates its formation with the support member 15 '', which is arranged near the front edge 36 of the support plate 17 so that a sufficiently stable undergrip for that with the scissor lift table 1 lifting cargo is formed.
