Definitions

  • the invention relates to a lifting device for an industrial truck Load suspension device is in operative connection and the at least one Has telescopic device, the telescopic device a telescopic hollow profile and has a telescopic cylinder, wherein for the telescopic hollow profile fixed base element and at least one extendable telescopic element are provided and the telescopic cylinder is a base part and at least one has extendable part.
  • Lifting devices or masts for industrial trucks are known, the two have laterally arranged masts, each of several nested rails exist.
  • the rails are by means of cross struts connected whereby an anti-rotation is achieved.
  • the rails can be extended by lifting cylinders and chain hoists as well as deflection rollers, whereby a load handler arranged on the extendable mast part with a load on it can be lifted.
  • the rails of such Lifting devices are always in the field of vision of the truck driver and impair the driver's view. From DE 198 15 122 A1 is one Lifting device of an industrial truck designed as a counterbalance forklift known, which consists of a telescopic cylinder.
  • the telescopic cylinder is here with an oval or a to provide a star-shaped cross section. Such a lifting device thus has a high construction effort for the anti-rotation device.
  • the invention has for its object a lifting device for an industrial truck to provide the driver 's view of the driver when the load is lowered Industrial truck not hindered and with the smallest possible number of simple Components gets along, it must be ensured that no instability through Rotation of the telescopic elements against each other about their longitudinal axis can occur.
  • the telescopic elements and the base element of the telescopic hollow profile is designed as a hollow profile and is and lead is prevented from rotating the telescopic elements.
  • the groove and Spring profile absorbs the torsional forces that occur.
  • the tongue and groove are on the telescopic elements attached that in the area of tongue and groove cancel the tensile and compressive forces against each other, in particular by the Bending stress due to an absorbed load.
  • the number of extendable telescopic elements provided is preferably the same or less the number of extendable parts of the telescopic cylinder.
  • the number is provided extendable telescopic elements by at least one less than that Number of extendable parts of the telescopic cylinder.
  • A is particularly preferred Telescopic hollow profile with three extendable telescopic elements together with one Telescopic cylinder provided with four extendable parts.
  • the 4-stage telescopic cylinder has a lower installation height with the same lifting height than a 3-stage telescopic cylinder with the same lifting height.
  • the inner clear cross section of the innermost telescopic element is expedient of the telescopic hollow profile larger than the outer cross section of the base part of the Telescopic cylinder.
  • the innermost telescopic element is above the retracted one Telescopic cylinder slidable and it will be the smallest possible height of the retracted lifting device reached.
  • the position of the telescopic cylinder inside of the telescopic hollow profile is also advantageous because the hydraulic cylinder thereby being surrounded by a protective cover, for example dirt holds.
  • the telescopic device with a load suspension device is particularly advantageous Active connection.
  • the Visibility conditions for the truck driver improved considerably.
  • the driver can look over the telescope in this state.
  • the field of vision the driver is not restricted in any way.
  • the low height installation dimension of the telescopic device also causes a Lowering the headroom of the industrial truck, causing the industrial truck can be used for low room heights.
  • the use of the telescopic device according to the invention eliminates the need for usual lifting masts necessary pull chains and pulleys. Furthermore maintenance is reduced because fewer parts are used, one Need lubrication. The assembly effort is also less than for conventional lifting devices equipped with two masts.
  • An anti-rotation device is particularly simple and can be manufactured with little construction effort Lifting device, the same aspects of safety and security Ease of use takes into account.
  • the anti-twist device can standard manufacturing processes are manufactured.
  • the proposed lifting device is suitable for use in addition to Forklifts also for hand pallet trucks.
  • the clear view is for the operator of the device of great advantage, since the load here almost exclusively in lowered state is transported.
  • Another application is the use of more than one telescope device in an industrial truck.
  • the invention is also in industrial trucks with a together with the Lifting device lifting cab can be used.
  • Figure 1 is a perspective view of an inventive Telescopic device with a hollow telescopic profile 1 that a base element 2 and three Telescopic elements 3a, 3b, 3c, has.
  • 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 telescopic hollow profile 1 are common Longitudinal axis A-A guided against rotation.
  • the anti-rotation device used is shown in FIG. 2 to see.
  • Figure 2 shows a plan view of a telescopic device according to the invention Telescopic cylinder 4 and telescopic hollow profile 1, the tongue and groove guide 7 in the Level lies parallel to the connecting straight line B-B and parallel to the common one
  • the longitudinal axis of the telescopic cylinder 4 and the telescopic hollow profile 1 runs (see FIG. 1, Axis A-A), and is cut perpendicularly from the connecting straight line C-C.
  • the Straight line C-C connects the load side of the truck with the Vehicle side.
  • the arrangement shown represents a tongue and groove guide 7, which in the neutral level. The tensile and compressive forces exerted by the Apply bending load to the lifting device due to the lifted load thus against each other. Thereby the stability of the lifting device is maximal, while at the same time the wear of the anti-rotation lock is extremely low.
