Definitions

  • the invention relates to an industrial truck according to the preamble of patent claim 1.
  • U.S. Patent No. 4,460,064 shows an industrial truck, which can overcome a difference in height, in particular between the ground and the bed of a truck.
  • two parallel wheel arms are pivotally connected about a horizontal axis to a drive part, so that they can be folded upwards.
  • the distance of the wheel arms from each other can not be changed.
  • the invention has for its object to provide an industrial truck, which allows a simple and inexpensive connection of the wheel arms with simple and effective readjustment with a change in Radarmweite.
  • the rear end of the wheel arms is secured to a bearing arm which extends approximately perpendicular to the wheel arm and which is fittingly and slidably received in at least one bearing opening of the frame or the bearing member.
  • a bearing arm which extends approximately perpendicular to the wheel arm and which is fittingly and slidably received in at least one bearing opening of the frame or the bearing member.
  • On the frame and / or in the load part locking means are provided with which the axial and rotational position of the bearing arms is releasably fixed.
  • bearing opening is to be equipped with sufficient axial length to ensure adequate support of the bearing arm.
  • the wheel arms can be moved in the bearing opening, wherein the locking means ensure that the wheel arms are set both in axial and in rotational position. If the bearing arm is out of round or polygonal in cross section, for example square, the rotational position is determined in this way. However, it can not be changed in this case. In this case, care must therefore be taken only for an axial securing of the assumed position.
  • the bearing arm is to be fixable in different rotational positions, it is to be provided with either a circular cross-section and to be received in a complementary bearing opening. If, however, the bearing arm is non-circular or polygonal in cross-section, then it is to be surrounded by a component having the bearing opening, which in turn is mounted limitedly rotatable in the frame or in the load part. In this case, then either this bearing component or the bearing arm is determined by suitable locking means in the direction of rotation.
  • the fixing of the bearing arms can be done in the axial and / or rotational position by means of a clamping device.
  • a fixation with the help of ringiten is possible.
  • an adjusting device can be provided which acts eccentrically to the axis of the bearing arms and thereby permits or causes a limited rotation of the bearing arms.
  • the bearing arm may be provided at intervals or continuously eccentrically with an axially parallel surface, and an adjusting screw acts with its end against the end of this surface to allow rotation of the bearing arm.
  • the already mentioned clamping device which also forms a second bearing opening, may be formed by two shells, which are clamped by means of two clamping screws against each other to set the bearing arm in the axial and rotational directions.
  • a drawbar guided truck 10 is shown in side view, but the drawbar is not shown.
  • the pallet truck 10 consists of a drive part 12 with a traction motor 14 and a mast 16, on which a not shown fork is guided adjustable in height. The adjustment is carried out by means of a lifting and lowering drive, also not shown.
  • a pair of wheel arms are mounted on its frame, one of which can be seen at 18. At the free end of the wheel arms load wheels 20 are mounted.
  • the wheel arms 18 have at the rear end at the top of a bearing member 22 which receives a bearing arm 24 in an opening.
  • the bearing arm 24 is connected by suitable means fixed to the bearing member 22.
  • the bearing arm 24 is shown without a wheel arm. It can be seen that the bearing arm 24 has a substantially circular cross-section, but at the free end is flattened at 26 for the purpose of non-rotatable mounting in the bearing component 22 (FIG. Fig. 1 ).
  • a bearing block 30 is mounted with a cylindrical opening 32. The bearing block 30 is welded to the sheet 28, for example.
  • the bearing arm 24 extends through the opening 32 and a concentric opening in the plate 28 to a clamping device 34.
  • the clamping device consists of a first jaw 36 which is fixedly secured to a plate 38 of the frame of the drive member 12 and a second jaw 40th
  • the jaws 36, 40 are tensioned against each other by two clamping screws, which are not shown here.
  • openings are provided in the clamping jaws 36, 40, as indicated at 42 and 48, respectively.
  • the jaws 36, 40 have semicircular shells with which they enclose the bearing arm 24 on opposite sides.
  • a plate 52 is mounted, which for illustration purposes in Fig. 2 as transparent as opposed to FIG. 3 ,
  • the plate 38 has a threaded bore 54, on which the mast 16 after Fig. 1 is appropriate.
  • the bearing arm 24 has a plurality of recesses 56 which are arranged eccentrically to the longitudinal axis of the bearing arm 24 at intervals.
  • the bottom 58 of the recesses 56 is approximately vertical.
  • a threaded hole 60 is provided, which, as in Fig. 4 shown, a set screw 62 receives.
  • the adjusting screw 62 is arranged so that it can engage with the recess 56, in particular with the bottom 58, as in Fig. 4 is shown. By changing the position of the adjusting screw 62, the rotational position of the bearing arm 24 also changes with the corresponding torque.
