Definitions

  • the present invention proposes improved means that are in particular suitable to adjust the horizontal axle base of equipments for lift trucks or the like.
  • such means are used on lift trucks to adjust in particular the horizontal axle base of front groups.
  • These groups are for instance taking units with a horizontal grip or fork units for transporting pallets or other units.
  • the present invention falls within the field of the devices for lift trucks and has the advantage that it improves the control of the working front units because the visibility of the operative zone is larger.
  • the lift trucks are used to lift heavy loads in storehouses, warehouses or other places where there is an exchange of wares.
  • These lift trucks are formed by a movable vehicle on the fore part of which an operative equipment or unit is mounted.
  • the operative unit consists for instance of forks or side gripping elements or any other assemblies shaped according to the characteristics of the loads to be moved.
  • the operative unit of a lift truck is arranged on a movable frame which is adjustable horizontally to set the lateral position of the equipment in respect to the centre of the lift truck.
  • actuating devices are mounted on the movable frame to permit the axle base to be adjusted between the gripping tools, namely, to adjust their respective distance.
  • the said actuating devices are formed by two opposite double-acting hydraulic jacks which are positioned in parallel to one another and one over the other in a central area of the movable frame so that it is possible to translate the one gripping tool or the other gripping tool or both gripping tools in both directions because the cylinder is mounted on the frame on one side while the rod is fixed to one of the tools on the other side.
  • the jacks are arranged in the central part of the frame, as already described, and are subjected to accidental impacts or thrusts which are provoked by the load to be transported, for instance while drawing the load itself, or by other factors, because both the rod and the cylinder are not inserted in any protection. As a matter of fact, the presence of a protection will obstruct the remaining poor visibility.
  • the immediate advantages of the present invention are an easier use of the truck with improved working conditions for the operator, in particular during the loading and unloading of the parcels to be transported and a longer duration of the actuating parts, the cost of repairs and replacements being thus reduced.
  • number 1 denotes an equipment according to the present invention on the whole.
  • This equipment consists of a frame 2 which is shaped according to a usual form. More precisely, the frame 2 is obtained by connecting couples of vertical and horizontal plates in such a way as to form a structure which is essentially rectangular and is open in the middle.
  • the frame 2 is mounted behind a support 3 and is adjustable according to horizontal translations in relation to the support itself in order to set out the lateral position of the equipment in relation to the centre of the truck.
  • two horizontal guides 4 and 5 are mounted on the fore side of the frame 2 and are arranged parallelly to one another, the first guide being over the second one.
  • the guides 4 and 5 are provided with slides 6 and 7 at their upper and lower parts, respectively. Couples of runners 8 and 8', 9 and 9' are mounted slideably on the slides 6 and 7.
  • the runners 8, 8' and 9, 9' form part of two operative units 10 and 11, as it appears from figure 1 and 2.
  • the couples of runners 8, 8' and 9, 9' are essentially C-shaped in order to include the profile of the slides 6 and 7.
  • each of both guides 4 and 5 shows a longitudinal groove 12 which is delimited by the inner sides of the slides 6 and 7.
  • the dimensions of the longitudinal grooves 12 permit the insertion of double-acting oil-pressure jacks 13 and 14 which are opposite to each other.
  • Antifriction elements are of course put between the runners and the slides to avoid a friction of such parts sliding reciprocally.
  • the peculiarity of the present invention consists in positioning oil-pressure jacks in the interior of guides 4 and 5 in such a way as to let the central space of the frame 2 free so that the operator has the possibility of following visually the loading and unloading phases of the operative units.
  • another advantage of the present invention consists in keeping the jacks in a position that is protected from accidental impacts in order to increase the possibility of duration of the jacks.
  • figures 1 and 6-11 show the application of these means of displacement on fork units and double fork units while figures 2-5 show the application of these means of displacement on lateral gripping units.
  • the upper guide has smaller dimensions and the relevant jack is put on the lower guide while in a variant as represented in figure 14 both guides have smaller dimensions and the relevant jacks are positioned out of the guides.
