Definitions

  • the invention relates to a forklift with a frame and one within the Frame arranged battery block, the frame having a side opening for Has removal of the battery pack in a substantially horizontal direction.
  • An electrically powered forklift of the type mentioned is with a Accumulators equipped battery block equipped for the drive, the Lift drive and other electrical units required energy available provides.
  • the frame of the forklift is designed such that the battery block by means of removed using a suitable device and a new battery pack inserted can.
  • a particularly frequent change of the battery pack is necessary if the forklift is used in multi-shift operation. In this case it becomes regular a discharged battery block in the forklift by a freshly charged one Battery block replaced.
  • a roller conveyor is arranged on the bottom of the battery compartment in the forklift.
  • This forklift-fixed roller conveyor can move the battery block in a horizontal direction be pushed onto an external roller conveyor located next to the forklift. So that the frame of the forklift despite the large side opening for the Battery pack has the required rigidity, it is known to be one below and to provide a profile to the side of the opening, on which the weight is also applied of the battery pack is supported.
  • Such a forklift is for example in the DE 100 05 285 A1.
  • a disadvantage of this known arrangement is that the roller conveyors for changing the batteries are absolutely necessary.
  • the present invention is based on the object of a forklift to train that the battery block in the forklift is driven under and for example raised by means of a pallet truck and through the side Opening of the frame can be moved.
  • the frame one Bend has resilient support at the top of the opening of the frame is arranged.
  • the essentially horizontal, in the longitudinal direction of the forklift arranged carrier gives the frame the required rigidity, the Carrier mainly experiences a bending load.
  • the carrier forms the upper one Edge of the frame opening.
  • the carrier is shaped in such a way that that it extends to the front of the opening of the frame.
  • the carrier leaves doing so from the horizontal section at the top of the opening into an Essentially vertical section above.
  • the vertical section forms the front edge of the frame opening.
  • the carrier is shaped in such a way that it relates to the Extends behind the opening of the frame.
  • an im Substantially vertical section of the beam the rear edge of the Frame opening.
  • the forklift frame is down in the area of the battery pack at least partially open.
  • the opening of the frame is dimensioned such that the Forks of a pallet truck intended for transporting the battery block directly with can contact the battery pack.
  • the frame also points in the area below the battery block, contact points for the battery block, via which the weight of the battery pack is introduced into the frame.
  • An advantageous embodiment is when the carrier is rigid with the front area a receptacle for a front axle of the forklift is connected. Of the Forces and moments emanating from the front axle can therefore be carried directly into the beam be initiated.
  • the carrier can be rigidly connected to the receptacle, for example welded or screwed. It is also possible to choose the carrier and the Support for the front axle as a common component, i.e. to be made in one piece.
  • the carrier is rigid with one in the rear area Rear weight of the forklift is connected.
  • the carrier is preferred by means of a screw connection directly with the cast rear weight connected. The forces acting on the carrier can thereby directly into the Rear weight can be initiated.
  • Figure 1 shows the frame of a forklift according to the invention in perspective View. This can be seen at the bottom and on the right side of the forklift Battery compartment 1. To the left side of the forklift, the battery compartment is through a Side wall 2 of the frame limited. The battery compartment 1 is at the top by a Sheet 3 limited, forward by another sheet 4.
  • the invention is direct Above the battery compartment, on the open side, a in the longitudinal direction of the Forklift extending carrier 5 arranged.
  • the carrier 5 is the load-bearing one Frame part on the right side of the forklift and is used to transfer forces and moments between the front and rear of the forklift. In In its front area it bends carrier 5 downwards and runs along the front plate 4 of the battery compartment 1.
  • the carrier 5 is rigid with in the front area a receptacle 6 connected to the front axle of the forklift.
  • the back Area is the frame, and thus directly or indirectly also the carrier 5, rigid with connected to a rear weight of the forklift, for what in the present Embodiment screw holes 7 are provided.
  • the battery compartment 1 which is open at the bottom, makes it impossible to change one battery blocks shown with a pallet truck under the battery compartment drive, lift the battery pack and move it out of the battery compartment. A new battery pack is inserted in the reverse order.
  • the Forks of the pallet truck are in the process of being removed or inserted a battery block between the uprising points 8 arranged on the frame which the battery pack stands during the operation of the forklift.
  • Figures 2 to 4 show different variants for the design of the cross section of the carrier 5.
  • the cross-sectional shapes are chosen so that the carrier 5 high Resistance moments with respect to torques around a horizontal or vertical Axis.
  • the carrier should use as little material as possible and thus be inexpensive to manufacture.
  • the ones described below Cross-sections can be used in the orientation shown, or rotated 180 degrees.
  • the carrier has a T-shaped profile and exists from a horizontal plate 10 and a vertical plate placed thereon 11.
  • the two sheets 10, 11 can be welded together, for example.
  • the variant according to Figure 3 also consists of a horizontal plate 10 and a vertical plate 12 placed thereon, which, however, on the plate 10 opposite end merges into the horizontal.
  • a hollow body 13 is used instead of a vertical sheet provided, which is placed on a horizontal plate 10.
