Definitions

  • the present invention relates to a lifting device in a goods-carrying vehicle with a load-supporting platform, said device having two lifting arms mounted each on one side of the load-supporting platform and each having a cylinder assembly for pivoting the respect ⁇ ive lifting arm about a transverse first shaft, one of the piston-rod unit and cylinder unit of said cylinder assembly being articulated about a transverse second shaft and the other of said units being articulated to said lifting arm about a transverse third shaft, each lifting arm being pivotable by means of the associated cylinder assembly between a rear lifting position and a front resting position.
  • Such lifting devices which are sometimes called tailgate lifts, are available in many different designs.
  • the prior art lifting devices are used for handling relatively heavy units, such as containers and cable drums.
  • their lifting arms of the prior art lifting devices When the lifting arms of the prior art lifting devices have taken their front resting position which is the lowest position in which the lifting arms are directed forwards, their cylinder assemblies which usually are hydraulic, and their lifting arms are positioned above the vehicle platform or a corresponding load-supporting surface. This is no disadvantage, when the vehicle is used only for transporting containers and the like which are loaded and unloaded from behind by means of a tailgate lift.
  • the object of the present invention is to provide a lifting device which makes it possible to readily load and unload goods both from behind and from the vehicle sides and which thus makes it possible to use the vehicle for transporting different types of goods.
  • this object is achieved by means of a lifting device which is of the type mentioned by way of introduction and which is charac ⁇ terised in that the two pairs of lifting arm and cylinder assembly are mounted each on one side of said load- supporting platform, such that both the lifting arm and the cylinder assembly are positioned below or on a level with said load-supporting platform, when the lifting arm has taken its front resting position, the centre of the third shaft being simultaneously positioned above the straight line connecting the centre of said first shaft with the centre of said second shaft.
  • the lifting device com ⁇ prises two channel elements arranged each on one side of the load-supporting platform and extending therealong, said channel elements having an upwardly open channel and the upper portion of said channel elements being posi ⁇ tioned below or on a level with the load-supporting platform, and the two pairs of lifting arm and cylinder assembly are each mounted on a channel element, such that both the lifting arm and the cylinder assembly are com ⁇ pletely inserted in the channel of the respective channel element, when the lifting arm has taken its front resting position.
  • each lifting arm has a planar surface and is designed such that the planar surface is positioned on a level with the load-supporting platform, when the lifting arm has taken its front resting position.
  • their planar surfaces When the two lifting arms are in their front resting position, their planar surfaces. thus form a lateral continuation of the load-supporting platform, whereby the width of the load-supporting surface is conveniently increased.
  • Each channel element preferably is U-shaped in cross- section, each lifting arm being made of a square tube.
  • FIG. 1 is a side view of a truck provided with a lifting device according to the present invention
  • Fig. 2 is an enlarged partial view and shows the lifting device in more detail
  • Fig. 3 is a perspective view of the truck platform and the lifting device in more detail.
  • the truck 1 shown in Fig. 1 comprises a platform 2 with sideboards 3 and a tailboard 4.

  • the lifting device is particularly used for loading and unloading from behind. This is illustrated in Fig. 1 by means of a load which is a container 5.
  • the tailboard 4 is removed when loading and unloading are to be effected by means of the lifting device.
  • the sideboard 3 is lowered on this side.
  • the lifting device On each side of the platform 2, the lifting device comprises a channel element 6 having an upwardly open channel and extending along the platform 2.

Abstract

Un dispositif de levage utilisé dans un véhicule de transport de marchandises pourvu d'une plate-forme de support de charge (2) comprend deux bras de levage (7), qui sont chacun montés sur l'un des côtés de la plate-forme de support de charge et qui comportent chacun une unité de vérin (10) servant à faire pivoter le bras de levage respectif autour d'un arbre transversal (9). Chaque bras de levage (7) peut pivoter grâce à l'unité de vérin associée (10) entre une position de levage postérieure et une position de repos antérieure. Les deux paires de levage (7) et d'unités de vérin (10) sont montées chacune sur l'un des côtés de la plate-forme de support de charge (2), de sorte que le bras de levage et l'unité de vérin sont tous deux positionnés au-dessous ou au niveau de la plate-forme de support de charge (2) lorsque le bras de levage se trouve dans sa position de repos antérieure.
