Definitions

  • This invention relates generally to counterweights for load lifting vehicles and more particularly to counterweights for battery-powered lift trucks.
  • U.S. Patent 3,367,441 discloses a counterweight box in which scrap iron may be placed. While this does provide for a counterweight of variable weight it does not provide for a compact counterweight of readily and accurately alterable weight.
  • the present invention is directed to overcoming one or more of the problems as set forth, above.
  • a frame has two spaced apart members. Each of these members has an upper surface portion and a bottom portion with an inwardly extending projection thereon. A component is removably supported on the upper surface portions and at least one counterweight is supported on the projectionsbeneath the component.
  • FIG. 1 is a diagrammatic side elevational view of a lift truck having a portion broken away therefrom incorporating an embodiment of the present invention
  • Fig. 2 is a transverse diagrammatic sectional view of the bottom portion of the lift truck of Fig. 1 taken along line II-II of Figure 1.
  • a counterweighted device is generally indicated by the reference numeral 10.
  • a lift truck 11 is shown, however the present invention is also suited for incorporation in many other types of counterweighted vehicles and stationary devices.
  • the lift truck 11 has a frame 12 which ineludes two spaced apart longitudinally extending frame members 13 running substantially parallel one to the other.
  • These frame members 13 are preferably of hollow substantially rectangular cross section and are each formed of two elongated L-shaped plates, an inner plate 14 and an outer plate 16, joined by welding or other means. This is best shown in Figure 2.
  • the frame members 13 each, have an upper surface portion 18 and a bottom portion 20.
  • Each frame member 13 has a projection 22 extending inwardly from, said bottom portion 20.
  • this projection 22 is an end portion 23 of said outer plate 16.
  • These projections horizontally extend from an innermost upwardly projecting face 24 of each frame member 13 toward the. other frame member 13.
  • the frame members 13 are so situated that the two upper surface portions 18 and the two projections 22 are, respectively, coplanar. These projections. 22 support aplurality of counterweights 26 placed between the frame members 13.
  • the counterweights 26 are thin, flat plates of metal.
  • the counterweights 26 have apertures 28 through, which an attachment means such as a plurality of bolts 30 can be used to secure the counterweights 26 to the projections 22. Attaching the counterweights 26 to the frame members 13 in such a fashion also serves to strengthen the frame 12. Alternatively, one or more of the counterweights 26 can be welded to the frame members 13 or simply allowed to rest freely thereon.
  • a sufficient vertical space is provided between the projections 22 and their corresponding frame member upper surface portion 18 to allow the placement of all the counterweights 26 which may potentially be needed without the uppermost portion of the uppermost counterweight 32 reaching an elevation higher than that of the upper surface portion 18.
  • additional counterweights 26 may be placed elsewhere on the lift truck 11.
  • a vehicle component 34 such as a battery unit.
  • a battery unit Resting upon the upper surface portions 18 of the frame members 13 is a vehicle component 34 such as a battery unit. There is preferably no contact between the battery unit and either a, counterweight 26 or the bolts 30, In the best application of the present invention the vehicle component 34 is readily removable so as to provide ready access to the counterweights 26,
  • the frame members 13 extend a longitudinal distance, sufficient to support said battery unit 34, a front axle 36 and a rear axle 38,
  • the counterweights. 26 may be advantageously positioned at an elevation on said lift truck 11 lower than the elevation of, said axles 36 and 38, these elevations being with respect to the ground upon which the lift truck 11 rests.
  • the present invention provides a low profile counterweight or auxiliary counterweight system best suited for applications requiring space conservation, a low center of gravity, and simplicity and swiftness in altering the degree to which a device is counterweighted.
  • the counterweights 26 are placed in the space elevationally bounded by the frame member upper surface portion 18 and the bottom portion 20, the counterweights 26 are positioned as low as is possible on the vehicle 10 relative to the surface upon which the vehicle 10 rests without altering the ground clearance thereof.
  • the center of gravity of the vehicle 10 is thereby maximally lowered per unit weight of counterweight 26 added-. Additionally, these counterweights can be placed as far rearwards on the vehicle 10 as is possible to improve longitudinal stability.

Abstract

Systeme de contrepoids pour un dispositif (10) possedant deux organes de chassis espaces (13) sur lesquels repose un composant demontable (34). Des elements en saillie (22) s'etendent l'un vers l'autre depuis une portion de fond (20) sur chaque organe de chassis (13), ces elements en saillie etant positionnes a une certaine distance au-dessous du composant (34). Une pluralite de contrepoids (26) minces et demontables s'appuie sur ces elements en saillie (22). Le nombre, et par consequent le poids total, de ces contrepoids (26) peut etre modifie facilement lors du demontage du composant (34). L'invention decrite permet de realiser un systeme de contrepoids de poids variables presentant un centre de gravite surbaisse et s'applique notamment a des chariots de levage alimentes par une batterie (11) et analogue.
