Definitions

  • the present invention relates to forklifts and more particularly but not exclusively to forklifts having a track drive and which forklifts are adapted to be mounted on or towed by a truck.
  • a forklift including a main frame; a pair of parallel transversely spaced longitudinally extending driven endless tracks movably supported on the frame and adapted to engage a ground surface to support the forklift; support means mounting said tracks on said main frame, each support means including a stabiliser bar extending longitudinally of the frame so as to be generally co-extensive with an associated one of said tracks, said bar being resiliently defor able and being supported on its
  • OMPI extremities on said frame a plurality of idler rollers rotatably mounted on said bar so as to be rotatable about axes extending transversely of the forklift, said rollers being positioned so as to engage a portion of the track engaged with said earth surface, and wherein said idler rollers are biased to engage said portion so as to distribut the weight of the forklift along the track.
  • Figure 1 is a schematic perspective view of a forklift
  • Figures 2 and 3 are schematic perspective views of the forklift of Figure 1 with the tynes thereof in different positions;
  • Figure 4 is a schematic side elevation of the track arrangement employed in the forklift of Figure 1;
  • Figure 5 is a schematic side elevation of an alternative track arrangement to that of Figure 4.
  • Figure 6 is a schematic end elevation of the track arrangement of Figure 5.
  • the forklift 10 of Figure 1 is provided with a chassis 11 to which is rigidly fixed track supports 12 to which is rotatably mounted two pairs of rollers 13 around which pass tracks 14. Supported on the chassis 11 is a vertically extending member 15 which acts as a support for the tyne assembly 16. The member 15 is movably mounted on the chassis 11 so as to be movable from a forward position
  • the tyne assembly 16 is also movable between a low position whereby a load is either received or delivered from the tynes to a raised position whereby the load is supported by the forklift 10.
  • a load is first lifted by the forklift 10 when the tynes are in the forward position depicted in Figure 2.
  • the load is subsequently raised and moved rearwardly and therefore the tynes are lowered so that a substantial part or the whole of the load is supported by the chassis 11.
  • the track n ⁇ r 5 assembly 17 includes the supports 12 which rotatably support the rollers 13. Around the rollers 13 passes the track 14. In the present instance there is provided a plurality of upper idler rollers 18 which support the upper portion of th track 14 as it passes along the support 12. The lower 10 portion of the track 14 is supported by idler rollers 19 which in turn are attached to a stabiliser bar 20 extending between portions 21 of the support 12.
  • One of the rollers, in this particular instance the roller 13A is mounted so that its central axis is movable along the slot 22 to allow 15 the track 14 to deflect upwardly to the position 14A.
  • the idler rollers 19 also move upwardly however the track 14 is biased to its lower position by mean of a suspension which engages the idler rollers 19.
  • a suspension may be an air bag suspension which, by adjustment 20 of the pressure in the air bags, the load carried by various portions of the track 14 may be adjusted.
  • the forklift 10 is more adaptable to use in areas which would be sensitive to high loading. e.g. concrete driveways or 25 concrete slabs whereby it would be of a considerable disadvantage for the load to be concentrated on a very small area. In the present instance the entire load is spread along the two tracks 14 thus obviating concentration of the load. • 30 Turning now to Figures 5 and 6 wherein there is schematically illstrated an alternative means for mounting the stabiliser bar 20A on the track supports 12. One end of the stabiliser bar 20A is attached to a lever 22 which is pivotally attached to the support 12 by means of a pin or 35 axle 23. Preferably the bar 20A is also pivotally attached to the lever 22 by a pin 24.
  • the lever 22 would be resiliently biased to a predetermined position on the support 12 so as to bias the end of the stabiliser bar 20A to which it is attached, to a predetermined position. However, upon the track 14 being deflected together with the rollers 19, the lever 22 would be forced to pivot as the stabiliser bar 20A is also deflected.
  • the lever 22 is provided to enable one end of the stabiliser bar 20A to move relative to the support 12.
