Definitions

  • the invention relates to a lifting device for a truck, with a Load-receiving means is in operative connection and the at least one Teleskopeinnchtung, wherein the telescopic device a telescopic hollow profile and a telescopic cylinder, wherein for the Teleskofohlprofil a fixed base element and at least one extendable telescopic element are provided and the telescopic cylinder a base part and at least one has extendable part.
  • lifting devices or masts for trucks the two have laterally arranged lifting masts, each consisting of several consist of telescoping rails.
  • the rails are by cross struts connected whereby an anti-rotation is achieved.
  • the rails are extendable, whereby arranged on the extendable mast part load-carrying means with a can be raised thereon load.
  • the rails of such Lifting devices are constantly in the field of vision of the driver of the truck and affect the driver's view.
  • a Lifting device designed as a counterweight forklift truck known, which consists of a telescopic cylinder. This will allow in the retracted state, the lifting device is no longer the driver's field of vision limits.
  • the telescopic cylinder is here with an oval or a to provide star-shaped cross-section. Such a lifting device thus has a high construction cost for the rotation on.
  • the invention is based on the object, a lifting device for a truck to provide the view of the driver of the vehicle when the load is lowered Truck is not obstructed and with the least possible number of simple Components manages, while it must be ensured that no instability by Rotate the telescopic elements against each other about their longitudinal axis can occur.
  • the telescopic elements and the base element of the telescopic hollow profile are designed as hollow profiles and with groove and spring guidance twisting of the telescopic elements is prevented.
  • the groove and Spring profile absorbs the torsional forces occurring are particularly preferred Hollow profiles provided with a round cross-section.
  • tongue and groove are so on attached to the telescopic elements that in the area of the tongue and groove the tensile and compressive forces cancel each other, in particular by the Bending stress caused by a recorded load.
  • the number of provided extendable telescopic elements is the same or less than the number of extendable parts of the telescopic cylinder.
  • the number of provided extendable telescopic elements by at least one less than the Number of extendable parts of the telescopic cylinder.
  • a Telescopic hollow profile with three extendable telescopic elements together with a telescopic element Telescopic cylinder provided with four extendable parts.
  • the 4-stage telescopic cylinder with a lower installation height and the same lifting height as a 3-stage telescopic cylinder would have the same lifting height.
  • the inner clear cross section of the innermost telescopic element of the telescopic hollow profile larger than the outer cross section of the base part of the Telescopic cylinder. This is the innermost telescopic element on the retracted Telescopic cylinder sliding and it is thus the smallest possible height of reached reached lifting device.
  • the position of the telescopic cylinder inside Telescopic hollow profile is also advantageous because of the hydraulic cylinder surrounded by a protective shell, for example dirt keeps.
  • the telescopic device with a load-bearing device in Operatively connected.
  • this operative connection exists between the innermost Telescopic element and the load handling device, which preferably as a fork carriage is trained.
  • the gennge installation height of the retracted lifting device are the Visibility conditions for the driver of the truck significantly improved.
  • the driver can look over the telescope device in this state.
  • the field of vision the driver is therefore not limited in any way.
  • the low height adjustment of the telescope device also causes a Reduction of the headroom of the truck, causing the truck can be used at low room heights.
  • the telescopic device By using the telescopic device according to the invention eliminates the in the usual masts necessary traction chains and pulleys. Furthermore reduces maintenance because fewer parts are used, the one Need lubrication. Likewise, the assembly costs are lower than at conventional lifting devices equipped with two masts.
  • the realized by means of a tongue and groove guide Anti-rotation a particularly simple and manufacturable with low construction costs Lifting device, which equally aspects of safety and the Ease of use.
  • the rotation can by standard manufacturing processes are manufactured.
  • the proposed lifting device is suitable for use in addition to Forklifts also for hand pallet trucks.
  • the free view is for the operator of the device of great advantage, since the load here almost exclusively in the lowered state is transported.
  • Another application is the use of more than one telescope device in an industrial truck. For example, become two Teleskopeinnchtitch side by side, in the arrangement comparable to a conventional mast, used, there is the advantage that the Teleskophohlprofile with the same Wall thickness can be performed as the two U or I profiles of conventional masts.
  • the invention is also in industrial trucks with one together with the Lifting equipment liftable cab used.
  • FIG. 1 is a perspective view of an inventive Telescope device with a telescopic hollow profile 1, that a base element 2 and three Telescopic elements 3a, 3b, 3c.
  • the telescopic hollow profile 1 surrounds the Telescopic cylinder 4, which shows a base part 5 and four extendable parts 6a, 6b, 6c, 6d.
  • the telescopic cylinder 4 and the Teleskofohlprofil 1 are the common Longitudinal axis A-A guided against rotation.
  • the anti-twist device used is shown in FIG. 2 to see.
  • FIG. 2 shows a plan view of a telescopic device according to the invention Telescopic cylinder 4 and telescopic hollow section 1, wherein the tongue and groove guide 7 in the Plane is parallel to the connecting line B-B and parallel to the common Longitudinal axis of the telescopic cylinder 4 and the telescopic hollow profile 1 runs (see Fig. 1, Axis A-A), as well as being cut perpendicularly from the connecting straight line C-C.
  • the Straight line C-C connects the load side of the truck to the truck Side of the vehicle.
  • the arrangement shown is a tongue and groove guide 7, which in the voltage neutral level runs. The tensile and compressive forces of the Bending stress of the lifting device by recorded load herru, lift thus against each other. As a result, the stability of the lifting device is maximum, while at the same time the wear of the anti-twist device is extremely low.
