Definitions

  • the invention relates to an industrial truck with an electrical connection cable set, the industrial truck having a vehicle body and a lifting mast, on which a load handling device is arranged so that it can be raised and lowered, the connection cable set comprising at least one electrical connection cable that connects from the vehicle body to at least one on the lifting mast or on the Load handling means arranged electrical component is performed.
  • Industrial trucks have a lifting mast on which a load handling device, usually a load fork with two fork prongs, can be raised and lowered.
  • a load handling device usually a load fork with two fork prongs
  • electrical components that are arranged on the lifting mast or on the load handling device are increasingly being used, for example switches or sensors for determining the lifting height or the wear and tear of the forks and / or lighting devices that can be arranged on the lifting mast and / or on the load handling device.
  • an electrical connection cable set is provided as electrical cabling, which comprises at least one connection cable which is routed from the vehicle body to the electrical components arranged on the lifting mast or on the load handling device.
  • lifting masts with different overall lengths (lifting mast lengths) are used within an industrial truck series of a manufacturer, so that a corresponding length variation of the electrical cabling is required.
  • connection cable set can be made available for each length of a lifting mast, which is adapted to the corresponding length of the lifting mast.
  • vehicle-specific and adapted to the equipment of the industrial truck with lifting mast and electrical components would have to be manufactured, assembled and delivered. This leads to high manufacturing costs for the connecting cable set, high logistical expenditure and disadvantages when assembling the industrial truck, since flexibility during assembly is lost due to vehicle-specific connecting cable sets.
  • the length variance of the electrical cabling of the many different lengths of the lifting masts within an industrial truck series could alternatively be covered by a connecting cable set that is matched and designed for the lifting mast with the longest overall length. If this connecting cable set is used in a lifting mast with a shorter overall length, the connecting cable set would have to be wound up at a suitable point on the lifting mast. If the coiled connection cable set is loosely attached to the lift mast, it is exposed to the risk of damage and being driven off. In addition, the winding up and fastening of the wound up part of the connecting cable set during the assembly of the industrial truck is very time-consuming.
  • a connecting cable set usually has a flexible protective tube, for example a corrugated tube, in which the corresponding connecting cables are arranged so as to be protected from mechanical damage, the protective tube would have to be wound up and stowed in the cable storage for this purpose. Due to the required minimum bending radius of the flexible protective tube, however, a large, large-volume cable storage device is required, which has a large installation space and, when attached to the lifting mast, leads to a correspondingly large visual obstruction and restricted view of the truck operator on the load handling device.
  • the length variance of the electrical cabling of the many different lengths of the lifting masts within an industrial truck series could alternatively be covered by a connecting cable set that is designed as a spiral cable.
  • spiral cables are expensive to manufacture and have to be laid on the lifting mast in a complex manner and fastened in a complex manner in order to enable safe laying and fastening on the lifting mast in the rough use of industrial trucks.
  • an industrial truck which has a vehicle body and a lifting mast on which a load handling device is arranged so that it can be raised and lowered, the connection cable set comprising at least one electrical connection cable which leads from the vehicle body to at least one on the lifting mast or on the load handling device arranged electrical component is performed.
  • the connecting cables are accommodated in a tubular cable storage system, open at the top, based on the principle of a cable drum and are pulled out of the cable storage system when the lifting mast and thus the load handling device are raised or fed back into the cable storage device when the load handling device is lowered.
  • a telescopic guide for electrical cables in aircraft and spacecraft is known.
  • the telescopic guide forms a cable housing for a cable and is attached at the opposite ends to a fixed part and a movable part.
  • the telescopic guide is pulled apart or pushed together during the relative movement of the movable part to the fixed part.
  • the cable is arranged with a loop in the cable housing formed by the telescopic guide.
  • the US 2005/011657 A1 discloses an extendable / telescopic cable duct attached to a building wall of a room for routing television cables or computer cables along walls in a room.
  • the present invention is based on the object of providing an industrial truck with an electrical connection cable set with which the length variance of the electrical cables can be reduced with little construction effort and space requirement
  • Cabling of many different lengths of the lifting masts can be covered within an industrial truck series.
  • the connecting cable set has a length compensation to compensate for different overall lengths of the lifting mast, the connecting cable set having a telescopic protective device within which the connecting cable is arranged, the protective device comprising a cable store in which the electrical connecting cable is formed with a Loop is guided and stored.
  • the connecting cable set according to the invention is thus matched and designed for the lifting mast with the longest overall length.
  • the connecting cable set according to the invention comprises a telescopic protective device in which the unneeded length of the connecting cable can be stowed.
  • connection cable set With the connection cable set according to the invention, several different lifting masts with different lengths can be covered with a variant of the connection cable set by the telescopic protective device, so that only one version of the connection cable set is required for several different lifting masts with different lengths.
  • the length variance of the electrical cabling of many different lengths of the lifting masts within an industrial truck series can be covered with little construction effort.
  • connection cable set is that only the connection cable is wound up and stowed in the cable storage device, ie only the connection cable is wound up without a flexible protective tube surrounding the connection cable. Since the connecting cable is more flexible than the surrounding protective tube and allows a smaller bending radius, the cable storage requires only a small amount of space and thus space to accommodate the excess cable length. With an arrangement of the telescopic protective device comprising the cable storage device on the lifting mast, a reduced amount can thus be achieved compared with a cable storage device in which the protective tube of a connecting cable set is wound up and stowed away
  • the telescopic protective device has two protective sections which are adjustable in length to achieve length compensation, the electrical connecting cable being guided and stored between the two protective sections of the protective device forming the loop.
  • the protective device is thus divided into two protective sections at one point, which are mutually adjustable in length and thus telescopic.
  • the two protective sections form or limit the cable storage in which the connecting cable is wound without a surrounding protective tube.
  • the external mechanical protection of the connecting cable set formed by the protective device is thus telescopic and adjustable in length at one point, and the individual inner connecting cables of the connecting cable set are arranged and guided in the cable store delimiting the two protective sections in such a way that they allow the two protective sections to be pulled apart and pushed into one another.
  • the protective device can be designed as a flexible protective hose, the first protective section as an outer hose and the second protective section as an inner hose is formed, which is arranged adjustable in length in the outer tube, wherein the outer tube forms the cable storage in which the loop is received.
  • the inner tube and the outer tube are preferably arranged coaxially. As a result, the length of the inner tube can be adjusted in a simple manner relative to the outer tube and can be pushed into the outer tube or pulled out of the outer tube.
  • the inner hose is arranged so as to be adjustable by means of a fastening and guide device on the outer hose. This enables the inner tube to be guided in the outer tube and the inner tube can be fixed to the outer tube at the selected length setting.
  • the protective device can be designed as a telescopic protective tube, the first protective section being designed as an outer tube and the second protective section being designed as an inner tube, which is arranged adjustable in length in the outer tube, the two tubes forming the cable storage and in the Inside the two tubes the loop is added.
  • the cable storage of the protective device formed by the two tubes is thus adjustable in length and telescopic.
  • the outer tube and the inner tube are preferably arranged coaxially.
  • the inner tube can be adjusted in length in a simple manner relative to the outer tube and pushed into the outer tube or pulled out of the outer tube.
  • the outer tube and the inner tube are expediently each provided with at least one fastening device for fastening to the industrial truck.
  • the inner tube and the outer tube can be attached to the industrial truck in a simple manner in the selected length setting of the telescopic protective tube.
  • the protective tube is designed as a rigid protective tube, there is good protection of the connecting cable in the cable store formed by the telescopic protective tube.
  • the protective device can be designed as a protective tube, the first protective section being designed as a first protective tube and the second protective section being designed as a second protective tube, the two protective tubes being attached to a protective housing and at least one of the two protective tubes the protective housing is arranged adjustable in length, the protective housing forming the cable storage and receiving the loop.
  • Two protective tubes are thus arranged on the cable store, one or both of which are adjustable in length relative to the cable store and can thus be pushed into the cable store and pulled out of the cable store.
  • the first protective tube and the second protective tube are preferably arranged coaxially or parallel to one another on the protective housing. In this way, at least one of the two protective tubes can easily be adjusted in length relative to the protective housing and pushed into the protective housing or pulled out of the protective housing.
  • the two protective tubes are expediently designed as flexible protective tubes, in particular corrugated tubes.
  • the lifting mast has at least one vertical mast profile, the protective device being arranged on the mast profile. Due to the small space requirement of the telescopic protective device according to the invention, when the protective device is fastened to the mast profile, for example the mast profile of the standing mast, slight visual obstructions and visual restrictions for the operator of the industrial truck through the lifting mast to the load handling device can be achieved.
  • the invention further relates to an industrial truck series which has industrial trucks according to the invention with different lengths of lifting masts and is provided with a connecting cable set.
  • connection cable set according to the invention several different lifting masts with different overall lengths can be covered with a variant of the connection cable set through the telescopic protective devices, so that only one version of the Connection cable set for several different masts with different lengths within an industrial truck series is required.
  • the connection cable set according to the invention thus results in a small number of variants of the connection cable sets in order to be able to cover the electrical cabling of different lifting masts with different overall lengths within an industrial truck series.
  • the connection cable set according to the invention the length variance of the electrical cabling of many different lengths of the lifting masts within an industrial truck series can thus be covered with little construction effort.
