Definitions

  • the present invention relates to a self-propelled lift truck, in particular for palletized goods.
  • a self-propelled lift truck in particular for palletized goods.
  • Such a piece of equipment is intended specifically, though by no means exclusively, for loading and unloading palletized materials or merchandise into and from containers, covered vehicles, enclosures or warehouse space affording a rear access point only. Whether loading or unloading, the need exists in all such situations for the palletized load to be transferred through an essentially horizontal path.
  • the conventional lift trucks currently in use internal loading and unloading operations are ruled out for the most part, due mainly to the fact that the lift boom is required to operate under the most unfavourable conditions, namely, extended to its maximum outreach while disposed in a horizontal or sub-horizontal position.
  • the object of the invention is to obtain a notable simplification of the procedure thus described by eliminating the deck transfer operation effected with the manual transpallet and entrusting this same duty to a self-propelled lift truck which is able to operate externally of the enclosed stowing space utilizing a boom and fork assembly with the same dimensional, weight, lift capacity and reach specifications as those of equipment employed for loading and unloading in the conventional manner described above.
  • a self-propelled lift truck intended in particular for palletized loads, of the type having a cantilevered boom arm of which the projecting end carries a fork assembly and the remaining end is anchored to the body of the truck;
  • the lift truck disclosed is characterized in that it comprises means arranged in such a way as to create at least one additional support for the cantilevered boom and fork assembly, which consist in at least one load-bearing component associated permanently with the cantilevered assembly and capable of movement in a vertical direction relative thereto between two limit positions: a raised, inactive position, and a lowered position in which the component fulfils its prescribed function of a simple means of support capable of rolling on a surface beneath.
  • the advantages of the invention is that of its simplicity in construction.
  • 1 denotes a self-­propelled lift truck running on wheels 2, to the body 3 which of a telescopic boom arm 4 is mounted.
  • the boom 4 is anchored hingedly to the body 3 about a horizontally disposed pivot 5, the axis of which lies parallel to the axes of the paired wheels 2; the boom is caused to rotate about the axis of the pivot 5, hence raised and lowered, by a hydraulic cylinder 6 mounted between the body 3 of the truck and the boom itself.
  • the entire fork assembly 8 is able to rotate about the pivot 7 between a lowered position denoted A, in which the prongs 11 are horizontally disposed, and a raised position, denoted B, in which the prongs are angled marginally from the horizontal.
  • the wheels 13 are proportioned and positioned on the fork assembly 8 in such a way as to lie at least in part below the level of the lowest point of the fork assembly whenever the prongs 11 are in the raised position B. More exactly, it can be seen from fig 1 that, in position B, the combined weight of the forks 8, the load 9 and the boom 4 is taken by the wheels 13, which simply rest on a surface 15 afforded by and constituting the loading deck of the container 16 in which the full pallets 10 are stowed.
  • the lift truck 1, and the boom 4 in particular, are provided with an extra support by way of which to exploit the surface 15 afforded by the deck 15 of the container 16.
  • Rotation of the fork assembly 8 in either direction between position A and position B is produced by a hydraulic cylinder 17 mounted between the farthest projecting end of the boom 4 and the fork assembly itself.
  • the truck 1 can proceed to handle palletized loads 9 internally of the container 16 with no difficulty as regards the load-bearing capacity of the boom 4.
  • the additional support provided by the wheels 13 becomes available each time the configuration of fig 1 is reached, and the boom 4 can be manoeuvred without undergoing flexural stresses that would certain bear heavily upon it if cantilevered from the body 3 of the truck 1 with the far end unsupported.
  • the wheels 13 are mounted rotatably to a support 18 associated with the fork assembly 8 by way of a vertical slide, and the fork assembly 8 is traversed in the one direction and the other between a lowered and a raised position denoted A′ and B′ respectively, in relation to the support 18 and the wheels 13.
  • A′ a lowered and a raised position
  • B′ a raised position
  • the wheels 13 lie fully above a horizontal plane disposed tangential to the underside of the prongs 11
  • the wheels 13 lie at least in part below the same tangential plane, and are thus able to rest on the surface 15 afforded by the loading deck on which the pallets are stowed.
  • the wheels 13 might be mounted to an oscillating support, i e. pivotable about a horizontal axis and associated hingedly with the fork assembly or with the end of the boom 4.
  • a support would be rotated up and down by a hydraulic cylinder, or by another component able to perform the identical function, installed between the support and the fork assembly 8 or the end of the boom 4, in such a way as to permit of positioning the wheels 13 entirely above or at least partly below the level of the prongs 11.
