Definitions

  • the invention relates to a forklift according to the preamble of claims 1 or 3.
  • the support element consists of a linear guide that is formed by a roller-guided handlebar, which is able to absorb lateral forces and twists to avoid the mast.
  • a forklift is large Has overall height.
  • the present invention has for its object a simplified forklift truck of the type mentioned to provide with further improved stability.
  • this object is achieved in the case of a forklift according to the gate by the features of claims 1 or 3.
  • the tilt cylinder or cylinders at the level of the overhead guard the tilt cylinder forces not in the frame, but in the counterweight via two fixed columns initiated, which relieves the frame and increases the stability of the forklift.
  • the Support elements arranged parallel to one another are preferably in the overhead guard as load-bearing Elements are integrated and are rigidly connected by this. This arrangement ensures simple construction, low height.
  • the design is one below the driver protection device to be arranged cabin maximum design freedom also with regard to optimization given the view upwards, since the cabin does not function as with many known forklift trucks of a driver's canopy.
  • the Support elements designed as longitudinal beams, which are connected to one another by a plurality of crosspieces, each longitudinal beam is guided in a guide, each of which is arranged on one of two on the counterweight, Columns spaced from each other approximately perpendicular to the longitudinal axis of the vehicle are, with a tilt cylinder attached to each column.
  • the plug elements are designed as tilt cylinders, the cylinder tubes of which are rigidly connected to one another.
  • the tilt cylinder being a part form of it.
  • Two are on the counterweight to improve stability arranged columns spaced apart approximately perpendicular to the longitudinal axis of the vehicle provided, to each of which a tilt cylinder is attached and in the upper area by a cross member are interconnected. This results in an extremely stable and low-deformation Unit.
  • the forces introduced into this unit from the mast are applied to one or two columns passed, which are attached to the counterweight.
  • the cast counterweight deforms Force transmission practically not.
  • the cylinder tubes and the piston rods are each articulated to the mast and to the columns.
  • the overhead guard instead of training the overhead guard with the help of protective struts and webs, it is also possible to design the overhead guard as a mudguard.
  • Figure 1 shows a front seat forklift with a front mast 1 including attached Fork carrier 2, a rear counterweight 3 and one arranged between the mast and counterweight Cabin 4, in which the driver's workplace is located.
  • the mast 1 is approximately one Axle arranged at the level of the front wheel hubs can be pivoted.
  • On the counterweight 3 are two of each other spaced, approximately vertically arranged columns 5 attached, for example screwed, which is somewhat extend beyond the maximum cabin height.
  • the columns 5 are at the upper ends by a cross member 6 connected to each other.
  • each joint receptacle 7 there are 6 joint receptacles 7 at the ends of the cross member provided, in each joint receptacle 7 in each case a piston rod 8 of a tilt cylinder articulated is.
  • the two tilt cylinders are arranged parallel to each other.
  • the cylinder tube 9 each Tilt cylinder is articulated in an articulated receptacle 10 of the mast 1.
  • the supply the cylinder tubes 9 of the tilting cylinders with pressure oil take place via pressure hoses, not shown in the figure, which are attached to the mast.
  • the cylinder tubes 9 of the two tilt cylinders are diagonally divided by two crossing webs 11 connected to each other.
  • the webs 11 are parallel to the longitudinal axis of the vehicle attached protective struts 12 provided.
  • the webs 11 and the Protective struts 12 and 13 together with the tilt cylinders form a driver's canopy, which prevents them falling objects will injure the driver.
  • the size of the free spaces between the webs 11 and between the protective struts 12 and 13 depends on the size of the objects that are not through the open spaces should fall through. It is also possible to use a transparent but resilient space cover (high-impact resistant) pane, for example made of two when tilting the mast halves moving one above the other to prevent even small objects from falling through.
  • the support elements are formed by side members 14, which by several crosspieces 15 are connected to one another.
  • Each side member 14 is in an associated roller guide 16 guided, which is each arranged on a boom 5a of the column 5 in the area of the boom 5a the cross member 6, which serves to increase the stability of the connection between the two columns 5, is also attached.
  • the Side members 14 are in a suitable manner in the front region of the forklift, that is, preferably articulated, connected to the mast 1.
  • the two tilt cylinders on the boom are also preferably articulated 5a and the mast 1 attached.
  • the device shown is in solid lines in Figure 3 in the shown in the foremost position.
  • the dashed lines represent the rear area, with the back tilted Mast.
  • the connection of the longitudinal beams 14 to the roller guides can be made by means of a suitable profiling the side members are made.
  • the device described takes over in addition to the function of driver protection due to the rigid Cross-connection of the cylinder tubes 9 with one or more webs 11 the function of a torque arm, thus largely deformation of the mast due to load-related forces acting on the mast is prevented.
  • the hinge receptacles 7 and 10 are provided.
