Definitions

  • the invention relates to an industrial truck with at least one cabin, which has at least one column pointing upwards.
  • This at least one column is formed by struts, of which at least two run lengthways and at least one runs transversely to the at least one column.
  • At least one of the struts has opposite, wedge-shaped inclined surfaces. These inclined surfaces are aligned in such a way that the cross section of the at least one strut increases from the inside of the at least one column.
  • a generic industrial truck is manufactured by the Linde company under the type designation E25. This industrial truck therefore forms the closest prior art.
  • the invention has for its object to provide an industrial truck of the type mentioned, to which attachments can be attached with high assembly reliability.
  • An industrial truck has at least one cabin.
  • This cabin has at least one upward-facing column, which is formed by struts. At least two of the struts run longitudinally to the at least one column and at least one of the struts runs transversely to the at least one column. Between these struts, the at least one column has at least one opening and / or depression.
  • This structure makes the at least one column very stable so that it can withstand high forces.
  • At least one of the struts has wedge-shaped inclined surfaces, so that the cross section of the at least one strut increases inward from the outer surfaces of the at least one column.
  • clamping plates are provided which rest on at least one of the inclined surfaces of the at least one strut. These clamping plates at least partially cover the at least one opening and / or depression.
  • the clamping plates are each shaped to match the respective inclined surface and are biased against each other by holding means. This means that these clamping plates are firmly seated on the inclined surfaces and can withstand high torques.
  • At least one attachment is supported on at least one of these clamping plates.
  • the choice of attachments is basically arbitrary. It is primarily intended for restraint systems, exterior mirrors, lighting fixtures and driver assistance systems. However, this list is not to be understood as exhaustive.
  • the clamping plates it is advantageous if they are prestressed inwards by the outer surfaces of the at least one column.
  • the inclined surfaces convert the clamping plate tension into a force in the clamping plate plane, so that the clamping plates literally wedge on the inclined surfaces. This leads to a secure fixing of the clamping plates on the at least one column.
  • the at least one strut has at least three inclined surfaces, the at least one clamping plate abutting at least two of the inclined surfaces of the at least one strut.
  • the at least one clamping plate is thus fixed in two opposite directions by the inclined surfaces and can thus achieve a sufficient clamping effect without being in contact with another strut. This results in a particularly compact construction of the at least one clamping plate.
  • the at least one clamping plate rests on at least two of the struts. In this way, a sufficiently high clamping effect of the at least one clamping plate is also achieved. In this case, however, the at least one clamping plate must bridge the free space between the struts, so that overall a correspondingly enlarged structure results.
  • This measure has the advantage that the torques acting at least on one clamping plate can be better supported, which is particularly advantageous in the case of restraint systems for support on the at least one clamping plate.
  • the at least one clamping plate rests on at least two of the struts running longitudinally to the at least one column.
  • the at least one clamping plate rests on at least two of the struts running transversely to the column.
  • the at least one clamping plate rests on at least three of the inclined surfaces.
  • At least one screw has proven itself as a holding means for clamping the clamping plates to one another. In this way, high preloads can be generated with relatively little effort. Such connections are also very secure.
  • a restraint system for a driver of the industrial truck has proven itself for the at least one attachment part. Due to the geometric conditions, which are explained above, the resulting torques can be supported on the at least one column without any problems.
  • the at least one column Since the at least one column is very resistant to bending, it can also be easily attacked by a lifting cylinder which adjusts a lifting mast of the industrial truck. The bending moments that occur can easily support the at least one column.
  • An industrial truck 1 has a body 2, which is supported on wheels 3.
  • a driver seat 4 for a driver, not shown, is supported on the body 2.
  • This driver's seat 4 is surrounded by a cabin 5, which is essentially formed by columns 6 arranged at the rear.
  • lifting cylinders 7 are also supported, with which a lifting mast 8 can be adjusted in its angular position.
  • This mast 8 carries a fork 9 for receiving a load, not shown.
  • an attachment 12 in the form of a restraint system 10 which has a protective bracket 11.
  • This protective bracket 11 can be pivoted from the restraint position shown into an open position, not shown, in which the driver can simply enter or leave the industrial truck 1.
  • the columns 6 are formed by a plurality of struts 13. Two of these struts 13 run upwards along the column 6, while transverse struts 13 are provided between them.
  • This arrangement of struts 13 results in a very torsionally rigid structure, which ensures an optimal fixing of the restraint system 10.
  • the struts 13 have inclined surfaces 14 which from the two outer surfaces of the column 6 to Column center towards an increase in cross section of the strut 13. A free space 15 between the struts 13 therefore tapers from the outer surfaces of the columns 6 to the center of the column.
  • Clamping plates 16 are held on the inclined surfaces 14, which are shaped to match the inclined surfaces 14. These clamping plates 16 are biased against one another by means of holding means 17 in the form of screws. In this way, the surfaces of the clamping plates 16 press against the inclined surfaces 14 and result in a firm, torque-proof hold for the attachment 12.
  • FIG 3 shows an alternative embodiment, wherein the same reference numerals designate the same parts. The following is only the differences Figure 2 received.
  • the clamping plates 16 capture the entire free space 15 between the struts 13.
  • the clamping plates 16 thus rest on all edges 18 on the corresponding inclined surfaces 14 of the struts 13.
  • the clamping plates 16 are optimally clamped in order to support the greatest torques in different directions of rotation.
  • the clamping plates 16 have to be adapted very precisely to the shape of the struts 13.
  • clamping plates 16 grip the inclined surfaces 14 in each case one of the transverse struts 13.
  • the clamping plates 16 can thus be made particularly small. This results in a particularly simple construction, but at the expense of torque support in the vertical direction of rotation. In simple applications, however, this is sufficient.
  • clamping plates 16 in combination of the embodiments according to the Figures 2 and 4 train.
  • the clamping plates 16 grip the inclined surfaces 14 of adjacent, transverse struts 13, so that they extend over the free space 15 in an approximately vertical direction. This results in a particularly advantageous support of torques about a horizontal axis of rotation.
