Definitions

  • the invention relates to an industrial truck, in particular a pallet truck, with one a telescopic mast height-adjustable load suspension device, the A mast attached to a frame of the industrial truck and has a lifting mast that is movable in the vertical direction relative to the standing mast.
  • the standing mast is essentially fixed to the frame of the industrial truck.
  • hydraulically acting lifting cylinder can be relative to the lifting mast Standing mast can be raised.
  • a load handler is usually in the Usually a load fork, guided vertically on the mast and over a upper end of the mast linked chain connected to the mast.
  • a Lifting the mast by a certain amount by means of the hydraulic cylinder Height difference thus causes the load handler to be raised by twice Height difference.
  • Such a mast is for example in the Dr. Rödig's encyclopedia of industrial trucks, 1991 edition on page 62 as a simplex mast described.
  • the invention described below is in analog Can also be used with other types of masts.
  • the present invention is therefore based on the object of having an industrial truck an easy to manufacture device for displaying information about the To provide lifting height.
  • the mast means for has a visual representation of a lifting height of the load suspension device
  • the Standing mast and the lifting mast each have at least one marking. Both Markings are visually recognizable for the operator.
  • the lifting device means that the marking arranged on the lifting mast is relative to the Marking of the mast moved. From the relative position of the two Markings to each other can clearly draw conclusions about the lifting height of the Be lifted.
  • the markings can, for example by painting or by sticking to the mast and to the mast are attached and are preferably arranged such that they from the Operator can be identified during normal operation of the industrial truck.
  • the one arranged on the lifting mast Marking formed by a scale extending in the vertical direction and the length of the scale corresponds essentially to the maximum possible Path of movement of the mast. It is useful if the on the Standing mast arranged marking no significant extension in the vertical Direction and is arranged in an upper portion of the mast. At lifting the load handler will raise the mast with the scale up moves, with the scale shifting relative to the stationary mark. The When the marking is stationary, the operator can read the current one more easily Lifting height, because he can always look at the same place for this. At the mark adjacent point on the scale, the operator can see the current lifting height of the Read off the load handler.
  • a label on the scale advantageously refers to the lifting height of the Load lifting device.
  • the corresponding Color coding of the scale and the load diagram can Operator can read the payload diagram particularly easily and reliably.
  • FIG. 1 shows a side view of the industrial truck according to the invention.
  • a mast 4 consists of a mast 5 and a lifting mast 6.
  • the lifting mast 6 can move upwards along the standing mast 5 are extended, with a load suspension device 7 designed as a load fork automatically moves up along the mast 6.
  • the load suspension device 7 is always double raised like the mast 6.
  • Figure 2 shows the cross-section A-A of the industrial truck with fully lowered Load suspension device 7.
  • a hydraulic lifting cylinder 8 can be seen in this view its lower end on the frame 1 and its upper end on the mast 6 is attached.
  • a marking 9 is made in the upper area of the standing mast 5, which has no substantial extension in the vertical direction.
  • the lifting mast 5, however, has a scale-shaped marking 10, the dimensions of which refer to the lifting height h 3 of the load-carrying means 7. This is made clear to the operator by means of a pictogram 11 attached to the mast 5.
  • the marking 9 points to the value "0" of the scale-shaped marking 10. This means that the load-carrying means 7 is in its lowest position.
  • FIG. 3 shows the view of the industrial truck according to FIG. 2 with the load-carrying means 7 raised.
  • the scale-shaped marking 10 is shifted upward so that a value for the lifting height h 3 can be read at the point assigned to the marking 9.
  • the scale-shaped marking 10 has three sections in this exemplary embodiment with different colors a (green), b (yellow), c (red). These different from each other in color delimited sections indicate areas of the lifting height at which a different maximum permissible load of the load suspension device 7 is present.
  • the coloring of the scale-shaped marking 10 and the Load diagrams make it easier for the operator to read them quickly and safely of the payload diagram and thus reduces the risk of incorrect operation of the Industrial truck.
  • the payload diagram is easy for the operator accessible place of the truck, for example near Controls arranged.
