Definitions

  • the invention relates to a lifting carriage, in particular fork carriage for Industrial truck, consisting of a front plate for receiving a Load handler and a mounting flange for mounting the lifting carriage a lifting device.
  • the invention also relates to a method of manufacture a lifting carriage.
  • Lift carriage is designed as a fork carriage and consists of an upper and a lower guide profile.
  • the front panel is used to hold a load handler. Forks or an attachment, for example, a sideshift or a rotating device.
  • the lifting carriage is made up of several individual parts assembled, for example two legs, an upper and a lower Guide profile and, if applicable, vertical webs connecting the guide profiles.
  • the assembly of the individual components, some of which are forged can be formed takes place in known lifting carriages by means of welding.
  • the present invention has for its object a lifting carriage and a To provide a method for manufacturing a lifting carriage that a enable low manufacturing costs and lower manufacturing costs.
  • This object is achieved with respect to the lifting carriage in that the lifting carriage is made in one piece.
  • the configuration of the lifting carriage as a component results in a simple one Manufacturing with low manufacturing costs and low manufacturing costs, because on elaborate welds can be dispensed with and not one with several Components welded lifting carriage necessary straightening process is required.
  • the lifting carriage is as Cast component formed.
  • the lifting carriage by casting in a simple way the lifting carriage by exhausting the degrees of freedom of the Casting in terms of shape to specific requirements of the application be adjusted.
  • a lifting slide produced by casting points through the Elimination of the assembly of several components and the elimination of the Straightening process on low manufacturing costs and low manufacturing costs.
  • a lifting carriage in which the receiving flange of two spaced vertical legs is formed, there are special Advantages if there is at least one bearing journal on each of the legs a guide roller is arranged.
  • Screwable journals can be provided on the legs.
  • the bearing journal is integral with the Legs are formed.
  • the journals for the guide rollers are thus at a lifting slide designed as a cast component has already been cast on, as a result of which results in low construction costs and high stability in the area of the bearing journal.
  • only the cast-on bearing journals are used Editing a leadership role.
  • only the journal for the upper or lower guide rollers or the journals for the upper and lower guide rollers are formed on the legs.
  • the front panel as an upper and a lower horizontal guide profile is formed, there is a simple design of the lifting carriage arranged as a fork carriage on which fork tines or various attachments that can be used universally.
  • Safety devices are expedient in the area of the upper guide profile trained for the load handler. By cast on Securing devices, for example several grooves, can easily be Forks must be secured against slipping sideways.
  • a fastening element especially for a chain holder, designed for a lifting chain.
  • a chain holder for a lifting chain can thus be attached to the lifting carriage or formed in one piece on the lifting carriage become. Due to the degrees of freedom of casting can easily Chain holder for a lifting chain can be provided on the lifting carriage.
  • the lifting carriage can be tilted is provided relative to the mast of the industrial truck, there is a small Construction effort, if on the legs each have a receiving device for one Tilting device provided with guide rollers, in particular an eccentric shaft is.
  • a receiving device for one Tilting device provided with guide rollers, in particular an eccentric shaft is.
  • Through cast-on receiving devices, for example half shells for one Storage of an eccentric shaft forming the tilting device can be done in a simple manner Way an eccentric shaft which enables the tilting of the lifting carriage Lifting carriage can be rotatably supported.
  • a mounting flange for the tilting device is expedient here actuating drive, for example a hydraulic cylinder.
  • drive for example a hydraulic cylinder.
  • the lifting carriage as a cast component can be a mounting flange for one drive designed as a hydraulic cylinder, for example a fastening fork, can be easily cast on the lifting slide.
  • the view of that arranged on the lifting slide Load suspension devices are improved. With a cast lifting carriage, they are Openings can be produced in a simple manner using appropriate cores.
  • the object is achieved in that the Lifting carriage is poured.
  • a cast lifting carriage has low manufacturing costs and a low manufacturing cost. It is also by casting manufactured lifting sled possible in a simple manner by inserting different cores in a mold different variants of lifting slides for manufacture different types of industrial trucks.
  • a cast lifting carriage used as spheroidal graphite cast iron.
  • Spheroidal graphite cast iron points high strength and toughness and is particularly suitable for one Lifting.
  • the material is austenitic - bainitic Ductile iron is used.
  • An austenitic - bainitic cast iron has a high elongation at break and high strength values.
  • the lifting carriage can are subjected to a thermal treatment sequence after casting, which the structure changes in such a way that the material properties are improved become.
  • a lifting sled cast from austenitic - bainitic cast iron is thus comparable in material properties to a welded one Lifting carriage, with lower manufacturing costs due to the production by casting and a low manufacturing cost and high degrees of freedom in terms of Shaping are made possible.
  • FIG. 1 to 4 show a lifting carriage 1 designed as a fork carriage two forming a receiving flange 2 on a lifting device, no longer shown, spaced vertical legs 2a, 2b and a front panel 3.
  • the Lift carriage 1 is in one piece and designed as a cast component.
  • the front plate 3 has a lower horizontal guide profile 4a and an upper one horizontal guide profile 4b, by means of which as a fork or as Attachment-designed load suspension device, not shown, on the lifting carriage 1 can be attached.
  • the upper guide profile 4b is with several as grooves trained safety devices 5 provided, by means of which fork tines against lateral displacement can be secured.
  • the front panel 3 is designed such that in the upper region of the front panel 3 an opening 8 is provided. In the lower area of the front panel 3 is another Opening formed by means of a central, vertical strut 7 in lateral Openings 9a, 9b is divided.
  • the opening 8, 9a, 9b allow the view of the Driver through the front plate 3 on the forks or the attachment.
  • a bearing pin 10a, 10b in the lower region molded onto which, after mechanical processing, a lower guide roller can be rotatably attached.
  • receiving devices 11a designed as semicircular bearing shells, 11b, in which a tilting device, which is no longer shown, for example an eccentric shaft which is provided with upper guide rollers, can be arranged.
  • the receiving devices 11a, 11b further comprise each have a flange surface 12a, 12b formed on the legs 2a, 2b, by means of the a further bearing shells are attached to the corresponding leg 2a, 2b can.
  • a tilting device designed as an eccentric shaft, on which the Upper guide rollers are arranged, so the fork carriage relative to Mast are tilted.
  • An actuating device for example as Hydraulic cylinder trained drive can on a mounting flange 13, the Fork is formed and arranged in the lower region of the fork carrier on which Fork brackets are supported ..
  • the fork carrier By designing the fork carrier as a cast component, it is simple possible, for stiffening between the legs 2a, 2b and the front plate 3 Struts 15a, 15b, 16a, 16b forming stiffening ribs. You can also in a simple manner, the bearing pins 10a, 10b, the fastener 14, the Mounting flange 13, the bearing shells 11a, 11b with the flange surfaces 12a, 12b and the openings 8, 9a, 9b are formed on the fork carriage 1.
