Definitions

  • the invention relates to an industrial truck with a portal-type wheel chassis that has at least one lifting device for loads that can be carried and carried between the wheels of the chassis.
  • Gantry-like trolleys are usually multi-legged, generally four-legged.
  • the wheels are located at the lower ends of the legs of a portal-type undercarriage, which means that the undercarriages are multi-wheeled or four-wheeled.
  • the invention has for its object to provide a floor vehicle, the wheels of the chassis
  • the undercarriage consists of at least one front first traveling frame and at least one rear second traveling frame, that each traveling frame as a vertical stand with wheels articulated below and the stand above connecting crosshead existing portal is formed and that each drive frame has a projecting from the other frame connecting arrangement, the free end of each connection arrangement is connected to the other frame via joints.
  • the undercarriage of the industrial truck according to the invention thus consists of at least two single-axle vehicles, namely the first undercarriage and the second undercarriage, which are placed one behind the other so that their wheels each run in the same track.
  • Each traveling frame and thus each individual vehicle is connected to the respective other traveling frame or individual vehicle by means of the projecting connecting arrangement, the length of the connecting arrangement determining the distance between the traveling frames representing single-axle vehicles.
  • the connection arrangements form, based on a single-axle vehicle described above, the lateral drawbars.
  • the above-described system of a chassis offers, with sufficient load-bearing capacity, the advantageous flexibility of the joints, which ensures that none of the wheels loses contact with the ground during the movement of the industrial truck. This is not only advantageous for the drive, but also for the steering.
  • the vehicle Due to the above-described construction principle for the chassis, the vehicle has only a relatively low weight.
  • ⁇ and 8-wheel trolleys can also be easily assembled.
  • trolleys in tandem or multi-axis arrangement are also possible.
  • each stand consists of telescopic stand sections.
  • the upper stand end sections together with a connecting cross member form an approximately U-shaped component that serves as the crosshead of each traveling frame.
  • the lower stand sections each hold and guide one wheel or the wheels of the undercarriage.
  • Each crosshead of each traveling frame is in turn held longitudinally displaceably as a structural unit on the lower stand sections, for example in that upper stand sections which are part of the crosshead receive the lower stand sections in a form-fitting manner and are guided displaceably thereon.
  • Working cylinders in particular hydraulic cylinders, are preferably suitable as drive means for a displacement.
  • the portal height changes, so that the vehicle may, for. B. Gates from workshops can pass if they have a relatively low clearance height.
  • At least one running rail suspended from the cross members of the cross heads is provided as the actual lifting device for at least one crane trolley.
  • a corresponding hoist can be assigned to each crane trolley, for example a winch. It is particularly advantageous that the length of the running rail is greater than the distance between the travel frames, which depends on the projection of the connection arrangements. If two crane trolleys which can be actuated separately from one another are guided on the running rail, the working area of the crane trolleys can advantageously be extended to regions lying in front of or behind the traveling frame, into which the projection of the running rail extends.
  • connection arrangements are located on the stand sections, which are involved in the formation of the U-shaped crosshead. Because of the above-described longitudinal displaceability of these stand sections, the connection arrangements are thus lifted or lowered when the portal height is changed by pushing out or pulling in the crosshead.
  • the positively controlled movements of all longitudinally movable stand sections run parallel, with the running rail involved in the formation of the lifting device being raised or lowered simultaneously with the crane trolleys.
  • connection arrangement is designed similar to a triangular cantilever or cantilever with a horizontal bar and a diagonal bar, the corresponding heads of the horizontal bar and diagonal bar being connected one above the other to the respectively assigned column section of the respective crosshead and the free ends opposite the heads in the associated joint Connection to the other chassis are merged.
  • each connection arrangement with horizontal bar and diagonal bar as well as a console-like profile has the shape of a triangle, in particular a right-angled triangle.
  • the horizontal bar, the diagonal bar and the associated stand section form an approximately right-angled triangle.
  • connection arrangement is connected with the corresponding heads of the horizontal bar and diagonal bar to the associated stand section, from which it protrudes, by means of rotary bearings which are movable to the vertical axis.
  • the free ends of the connection arrangements could thus perform pivoting movements about a vertical axis of rotation which runs parallel to the vertical longitudinal axis of an associated stand section. This enables the undercarriage to be folded in more detail below from an operating position into a transport position with a smaller track width.
  • each joint for connecting the free end of the respective connection arrangement to stand sections of the respective other driving frame than by a right angle to the perpendicularly rotating axis and additionally by one vertical axis movable ball joint is formed.
  • each travel frame is equipped with a corner strut arranged between its crosshead and its connection arrangement articulated on it .
  • Each Eckverstrebung is held with particular advantage to the crosshead and / or connection arrangement releasably '. This makes it possible, when the corner strut is released, to pivot the crossheads at a predetermined angle to the longitudinal axis of the vehicle, which advantageously reduces the track width of the industrial truck.
  • the industrial truck can thus be brought into the transport position and easily returned to the operating position by spreading and fixing the corner struts.
  • corner struts can be detachably held with plug bolts, screw connections or the like.
  • a controllable mechanism could also be used, which takes over the function of the corner struts, but is advantageously designed such that it can be actuated in an advantageous manner in order to move the industrial truck at any time without prior set-up and assembly work Bring the operating position into the transport position and vice versa.
  • each suspension of the running rail on the cross members of the crossheads of the traveling frame is designed as a suspension which can be varied in the horizontal plane.
  • the adjusting elements can again comprise working cylinders, preferably hydraulic cylinders, which can be actuated via corresponding controls.
  • FIG. 1 is a side view of the industrial truck
  • 2 is a schematic overview of the chassis of the industrial truck according to FIG. 1 consisting of two travel frames, seen from the side,
  • FIG. 3 is a view of a traveling frame of the undercarriage seen in the direction of arrow III in FIG. 2,
