Definitions

  • the invention relates to a cross-lift truck with a chassis and a lifting mast arranged thereon between the front and rear wheels with forks which can be extended on both longitudinal sides, in particular for long loads.
  • Cross forklifts or side loaders of this type are known (DE-AS 11 66 699).
  • the mast is arranged on a rotating set, with the help of which the extendable forks can be directed to both sides.
  • the disadvantage is that due to the central arrangement of the mast on the bogie, the stability when loading is not very large. The load-bearing capacity can therefore generally not be fully exploited.
  • the arrangement of counterweights is structurally impossible or only possible to a limited extent due to the fact that the mast can be pivoted on all sides.
  • the invention has for its object to provide a cross forklift truck of the type mentioned in such a way that the greatest possible stability in load pick-up exists, without however having to accept restrictions with regard to the storage options on the vehicle.
  • the invention consists in that the chassis consists of a front and rear running part, each provided with a part of the wheels, which are connected to one another by an independent intermediate piece, which is guided transversely to their running direction and is provided with the lifting mast.
  • the new cross-lift truck therefore does not have a vehicle frame with a central incision for the lifting mast, rather the location of the central incision takes on an intermediate piece which can be moved on both longitudinal sides and is guided on the two running parts and therefore also without further can be designed so that it can be lowered between the two barrel parts and can also be provided with counterweights that are reciprocally pushed according to the direction and the long side of the vehicle, on which the intermediate piece with the lifting mast is not located.
  • the division of the known vehicle frame into two running parts and a section movable between them with the lifting mast opens up design options that were not available in previously known designs.
  • the intermediate piece can be displaceably guided, for example, via swivel levers, which are mounted on the axles perpendicular to the axles of the wheels on the front and rear running parts and on the intermediate piece.
  • the swivel levers can each be provided in pairs between the intermediate piece and each running part and can be designed as parallelogram links, so that with an exact guidance of the two running parts to one another, a parallel displacement of the intermediate piece to the sides is possible.
  • This embodiment also offers the advantage that the pivot levers can be designed as double-armed levers, on the arms of which, which protrude beyond the pivot axes on the running parts on the side facing away from the intermediate piece, counterweights for the load can be arranged.
  • the counterweights automatically swing out to the opposite side when the intermediate piece is adjusted, so that the total weight distribution is adapted to the respective load capacity.
  • the new cross forklift can therefore be constructed much lighter with the same load capacity.
  • the counterweights are always on the side opposite to the load suspension.
  • the driver's cab is expediently designed to be laterally adjustable; it can be slidably arranged on the front running part transversely to the direction of travel, in which case configurations are also available which, for example, provide a pivotable assignment of the driver's cab to the intermediate piece, so that the operator is placed directly next to the load-bearing fork.
  • configurations are also available which, for example, provide a pivotable assignment of the driver's cab to the intermediate piece, so that the operator is placed directly next to the load-bearing fork.
  • the driver's cab is swiveled. However, it is easier to move the driver's cabin on the front running section.
  • An advantageous embodiment of the new cross forklift also results from the fact that the steering and driving axles in their assigned running parts for horizontal guidance on the handlebars are fastened, which are arranged in the manner of parallelogram links and that presses, preferably hydraulic presses, are provided for vertical guidance, each of which engages on the right and left side of each axle.
  • the pressure in the presses of the steering and driving axles assigned to one side of the vehicle can be blocked or switched in parallel, or that the pressure in the presses can be controlled individually, then it becomes possible to base the load-handling triangles of the new forklift truck in each case to the load bearing side, this depending on the position of the intermediate piece with the lifting mast leads to mutual triangles of the vehicle relative to the axles, which is desirable in the case of a mutual load bearing.
  • the vehicle By loading the axle support presses on one side of the vehicle, the vehicle can be tilted to the side, and when the front and / or rear axle support presses are applied, the vehicle can be tilted in the longitudinal direction or the intermediate piece can be placed on the ground.
  • pivot levers connect the intermediate piece to the front or to the rear barrel part, can be pivoted independently of one another, which is possible by means of corresponding hydraulic cylinders. It can thereby be achieved that the entire vehicle kinks in itself, so that the lifting mast and thus the load can be pivoted horizontally to a certain extent, which in some cases is sufficient to be able to take up or set down a load.
  • the new cross-lift truck is able to place long loads on the left and right on the front and rear running parts, in which case the driver's cab must stand in the middle when it projects above the front running part.
  • the chassis which consists of a front running part 1, a rear running part 2 with wheels 3 and 4 respectively arranged on a steering and a driving axle and an intermediate piece 5, which is held transversely to the direction of travel 6 between the running parts 1 and 2.
  • the intermediate piece 5 is connected to the front barrel part 1 via the pivot arms 7a and 7b, which form a pair of parallelogram links, with the rear barrel part 2 and via pivot arms 8a and 8b which can be seen from FIGS. 3 and 4 and run symmetrically to the central transverse plane.
  • the swivel arms 7a and 7b or 8a and 8b are mounted on bolts 9 of the intermediate piece 5, the axes of which are perpendicular to the axes of the wheels 3 and 4 and they are pivotably held on the rear and front running parts 2 and 1 on bearing bolts 10 which are likewise aligned.
  • bolts 9 'on the intermediate piece 5 and bolts 10' on the front barrel part 1 are provided for the swivel arms 8a and 8b.
  • a known telescopically extendable mast 11 with the load suspension forks 12 is provided , whose length is approximately such that they - see Fig. 3 - fill the width of the space between the running parts 1 and 2 when the intermediate piece 5 with the mast 11 is on one side of the vehicle.
  • a second pair of load-bearing forks 12 ' is provided on a frame 13 projecting to both sides of the lifting mast 11, both load-bearing fork tines 12 and 12', respectively, being designed to be foldable, so that the pair of load-bearing forks which is not in use is not from Frame 13 and from the mast 11 protrudes to the side.
  • Both the pivot levers 7a, 7b and the pivot levers 8a and 8b which each form parallelogram link pairs, are designed as double levers and extend with an arm 7a 'or 7b' and 8a ', 8b' over those provided on the running parts 2 and 1, respectively Swivel axes 10 and 10 'to the side facing away from the intermediate piece 5 and are connected there with counterweights 14 which are also articulated via swivel bolts 15 on the arms 7a', 7b 'or 8a' and 8b '. These counterweights 14 are thus automatically displaced when the intermediate piece 5 is moved into the position opposite the position of the intermediate piece 5 with respect to the longitudinal center plane 16.
  • the pivoting range and the respective end position of the pivot axes 10 and 15 are indicated by dash-dotted lines.
  • the swiveling movement is triggered by hydraulic pressure cylinders 16, which act on one of the swivels lever, in the embodiment, engage the rear pivot lever 7a and the front pivot lever 8a.
  • the manner of steering the wheels 3 of the front running part 1 or driving the drive axle 17 with the wheels 4, which is carried out via the motor 18, is not shown.
  • the design in this regard corresponds to the known transverse forklift.
  • the driver's cabin 19 along the guide rails 20 or the differently designed guide rails 21 shown in FIG. 4, which is displaceable on the front running part 1.
  • the driver's cabin 19 can therefore, as shown in FIG. 1, be pushed to the side opposite to the loading side.
  • the material gripped by the lifting forks 12 can then be gripped at the side of the vehicle and deposited on the upper loading areas of the front and rear running parts 1 and 2.
  • both the steering axle 23 of the front wheels 3 and the drive axle 17 with the rear wheels 4 each have a pair of parallelogram links 24, 25 and 26, 27 on the associated frame parts 28 and 29 of the front running part 1 and the rear running part 2 are guided in the horizontal direction, and that they are supported in the vertical direction by preferably hydraulic presses in the form of hydraulic cylinders 30 and 31 on the front and by hydraulic presses 32 and 33 on the rear barrel part 2. Since each of the two axles 17 and 23 is supported on the side of each wheel by a hydraulic press, with a corresponding control of the pressure in these hydraulic presses, a mutual arrangement of the stationary triangles of the vehicle can be effected. On the other hand, the inclination of the vehicle can also be influenced, as will be explained in the following.
  • the triangle 35 of the vehicle has the base 35 'directed to the side, on which the lateral load is also carried out via the fork 12'.
  • This triangle is achieved in that the hydraulic presses 31 and 33 are hydraulically connected in parallel and the hydraulic presses 30 and 32 are blocked. If the load is taken from the other side, the presses 30 and 32 are correspondingly connected hydraulically in parallel and the presses 31 and 33 are blocked.
  • the standing triangles can also be mutually aligned, since, in addition, the counterweights 14 each lie on the side of the central longitudinal axis 26, which lies opposite the intermediate piece 5, so that a very large load-bearing capacity can be achieved with little Realize the weight of the vehicle.
  • the two hydraulic cylinders 16, which actuate the swivel levers 7a and 8a can be actuated independently of one another. It can then be achieved that when only one pair of pivot levers is applied, the vehicle kinks in itself, so that the intermediate piece 5 and herewith the lifting mast 11 can be pivoted horizontally with the load, which is advantageous in certain applications.
