Definitions

  • the present invention relates to an industrial truck, such as a forklift truck. More specifically, the present invention relates to a battery-driven industrial truck.
  • the plate member 17 may be replaced by another connecting member that is not in the form of a single plate, but may include e.g. a plurality of bar members.
  • the U-shaped member may be formed in one piece, may be connected to the counterweight 11 by means of releasable fastening means (such as screws) and may be connected to the front frame portion 13 by means of releasable fastening means (such as screws) .
  • the battery assembly 12 (in particular the longitudinal members 14) can be fixed to the counterweight by means of releasable fastening means, such as screws 24.
  • the battery assembly 12 (in particular the longitudinal members 14) can be fixed to the front frame portion 13 by means of releasable fastening means such as screws.
  • the longitudinal members 14 include flanges 23, 25 at opposite ends that are joined to the counterweight 11 and the front frame portion 13, respectively, e.g. by means of the releasable fastening means 24.
  • the battery assembly 12 in addition to supporting the battery cells, serves as bearing structure in the industrial truck; accordingly, the longitudinal members 14 are dimensioned to withstand the operational stresses transferred between the lifting means 18 and the front axle on the one hand, and the counterweight 11 on the other hand.
  • the longitudinal members 14 are fixed to the counterweight 11 and to the front portion 13 of the frame by means of releasable fastening means. This allows to manufacture industrial trucks of different sizes while using always the same design for the counterweight and the front frame portion, by simply preparing battery assemblies of different size in the longitudinal direction. Hence, different wheel bases can be achieved in a cost-effective manner.

Claims (15)

  1. Elektrisch betriebenes Flurförderfahrzeug, umfassend:
    - eine Hebeanordnung (18) zum Heben einer Last,
    - ein Gegengewicht (11), das der Hebeanordnung gegenüberliegt, um das Gewicht der Hebeanordnung und einer von der Hebeanordnung gehobenen Last auszugleichen,
    - einen Vorderrahmenabschnitt (13), der konfiguriert ist, die Hebeanordnung zu stützen, und
    - eine Batterieanordnung (12),
    dadurch gekennzeichnet, dass die Batterieanordnung (12) umfasst:
    - ein Gehäuse (15), das eine Aussparung (16) zum Empfangen einer oder mehrerer Batteriezellen umfasst, und
    - zwei Längselemente (14), die mit dem Gehäuse (15) auf gegenüberliegenden lateralen Seiten der Aussparung (16) verbunden sind,
    wobei die Längselemente (14) das Gegengewicht (11) und den Vorderrahmenabschnitt (13) auf gegenüberliegenden lateralen Seiten des elektrisch betriebenen Flurförderfahrzeugs verbinden und konfiguriert sind, Kräfte zwischen dem Gegengewicht (11) und dem Vorderrahmenabschnitt (13) während des Betriebs des elektrisch betriebenen Flurförderfahrzeugs zu übertragen.
  2. Elektrisch betriebenes Flurförderfahrzeug nach Anspruch 1, wobei die Längselemente (14) mit dem Gegengewicht (11) mittels lösbarer Befestigungsmittel befestigt sind.
  3. Elektrisch betriebenes Flurförderfahrzeug nach Anspruch 2 wobei die Längselemente (14) mit dem Vorderrahmenabschnitt (13) mittels lösbarer Befestigungsmittel befestigt sind.
  4. Elektrisch betriebenes Flurförderfahrzeug nach Anspruch 3, wobei die Längselemente (14) Flansche (23, 25) an gegenüberliegenden Enden umfassen, die mit dem Gegengewicht (11) und dem Vorderrahmenabschnitt (13) verbunden sind.
  5. Elektrisch betriebenes Flurförderfahrzeug nach einem der Ansprüche 1-4, wobei die Batterieanordnung (12) ein U-förmiges Element (14, 17) umfasst, das zum Vorderrahmenabschnitt (13) hin offen ist, wobei das U-förmige Element die zwei Längselemente (14) und ein Verbindungselement (17) umfasst, das die hinteren Enden der Längselemente (14) nahe dem Gegengewicht (11) verbindet.
  6. Elektrisch betriebenes Flurförderfahrzeug nach Anspruch 5, wobei das U-förmige Element in einem Teil gebildet ist, mit dem Gegengewicht (11) mittels lösbarer Befestigungsmittel verbunden ist und mit dem Vorderrahmenabschnitt (13) mittels lösbarer Befestigungsmittel verbunden ist.
  7. Elektrisch betriebenes Flurförderfahrzeug nach einem der Ansprüche 1-6, wobei das Gehäuse (15) zwei gegenüberliegende laterale Wände umfasst, wobei eine erste der beiden gegenüberliegenden lateralen Wände an einem ersten der zwei Längselemente (14) befestigt ist und eine zweite der beiden gegenüberliegenden lateralen Wände an einem zweiten der zwei Längselemente (14) befestigt ist.
  8. Elektrisch betriebenes Flurförderfahrzeug nach Anspruch 7, wobei die lateralen Wände des Gehäuses (15) an den Längselementen (14) mittels lösbarer Befestigungsmittel (22) befestigt sind.
  9. Elektrisch betriebenes Flurförderfahrzeug nach Anspruch 7 oder 8, wobei die zwei gegenüberliegenden lateralen Wände des Gehäuses (15) substantiell vertikal sind und gegen eine vertikale Oberfläche der Längselemente (14) anliegen.
  10. Elektrisch betriebenes Flurförderfahrzeug nach einem der Ansprüche 1-9, wobei die nach unten gerichtete Oberfläche der Batterieanordnung (12) nicht in Kontakt mit Teilen eines Rahmens des Flurförderfahrzeugs steht.
  11. Elektrisch betriebenes Flurförderfahrzeug nach einem der Ansprüche 1-10, wobei sich ein unterer Teil des Gehäuses (15) abwärts in einer Höhe unterhalb der Längselemente (14) erstreckt.
  12. Elektrisch betriebenes Flurförderfahrzeug nach einem der Ansprüche 1-11, wobei die Längselemente (14) eine substantiell planare Form aufweisen und gemäß einer substantiell vertikalen Ebene orientiert sind.
  13. Elektrisch betriebenes Flurförderfahrzeug nach Ansprüchen 5 und 12, wobei das Verbindungselement (17) eine substantiell planare Form aufweist und gemäß einer substantiell vertikalen Ebene orientiert ist.
  14. Elektrisch betriebenes Flurförderfahrzeug nach einem der vorstehenden Ansprüche, wobei die Batterieanordnung ein laterales Batteriemodul (21) umfasst, das an der Seite des Flurförderfahrzeugs zwischen einem der Längselemente und einem lateralen Außenelement (20) des Flurförderfahrzeugs montiert ist, das so konfiguriert ist, das laterale Batteriemodul (21) vor äußeren Einflüssen zu schützen.
  15. Elektrisch betriebenes Flurförderfahrzeug nach einem der vorstehenden Ansprüche, wobei sich die hinteren Enden der Längselemente (14) auf einer Höhe ganz über Hinterrädern des Flurförderfahrzeugs befinden und die vorderen Enden der Längselemente (14) zumindest teilweise auf der Höhe von Vorderrädern des Flurförderfahrzeugs liegen.
