Definitions

  • Lifting devices of this type are known in many variants from the prior art. They are used for lifting and lowering as well as for transporting various objects or even for transporting persons.
  • lifting devices Depending on the load to be transported or lifted or lowered, different requirements are placed on lifting devices. If a lifting device is provided for a heavy load or if a load is to be lifted to a great height, for example a different chassis makes sense than with light loads and low lifting heights. In addition, it is possible that special environments may require special landing gear so that the load can be picked up from the starting point of a transport or delivered to the destination.
  • the present invention is based on the problem to meet the different requirements for a chassis of a lift truck.
  • the chassis is modular. Modular in this sense, that the chassis is composed of several parts. The parts have connecting structures through which they are connected. Such a modular chassis may be composed of different parts depending on the requirements of a type of construction kit, as long as mutually exchangeable parts have the same connection structures for connection to the other parts of the chassis or the lift truck.
  • the parts can be monolithic.
  • the side parts and the cross member may be modules of the chassis.
  • the side panels can be varied to meet specific requirements, without the crossbar must be changed.
  • the cross member can be varied without the side parts must be changed. Only the connection structures must be maintained so that the connection between the parts can be made.
  • the cross member may be monolithic.
  • chassis As a whole, but also the side parts of the chassis can be modular. This increases the modularity of the entire chassis.
  • Each side member may comprise a plurality of monolithic sections joined together and modules of the modular side panels.
  • the sections of each side part may have connecting structures, via which they are connected to a further section of the side part and / or to the cross member.
  • Each side part of a lifting device according to the invention may comprise a first portion, a second portion and a third portion, which are interconnected.
  • the cross member may be connected to a third portion of each side part.
  • first sections, the second sections and / or the cross member are hollow profiles with a uniform in their main extension direction cross-sectional profile.
  • the hollow sections may be tubes, in particular rectangular tubes, which can be produced by cutting to length from a longer tube. This makes it possible without special storage for the modules of the side parts or the cross member, depending on the requirements of the truck to be manufactured, to cut off the tubes required for the production of the modules.
  • the first sections, the second sections and / or the cross member may at least at one end and / or the cross member at both ends each have a recess as a connection structure.
  • the third sections can have protruding areas, which each have a cross section which corresponds to at least one clear cross section of a recess provided as a connection structure.
  • the protruding areas can then be plugged into the recesses for connecting the third section to the first and / or the second section and / or to the cross member.
  • first section, the second section and / or the third section of each side part are connected to one another by plug connections.
  • the third portions of the side parts and the cross member may be interconnected by connectors.
  • the connectors can be secured by pins, screws or other against loosening.
  • the third section of a lifting device according to the invention may be a cast part.
  • the first sections of the side panels can be the same.
  • the second portions of the side panels may be the same.
  • the third sections of the side parts can be surface-symmetrical to each other.
  • the roll holders and the rolls can be the same in pairs.

  • the chassis 2 has two mutually parallel side parts 3, 4, which are interconnected by means of a cross member 5, which extends transversely between them.
  • cross member 5 may be a rectangular tube or another profile part with a uniform over its length profile cross-section.
  • Each of the two side parts 3, 4 comprises a front (first) section 30, 40 (see in particular Fig. 4 ), which is preferably formed as a profile part with a uniform cross-section, in particular as a rectangular tube.
  • Each of the two front portions 30, 40 of the side parts 3, 4 has a free end, to which a roller 44, a roller 44 is attached via a first roller holder 33, respectively.
  • These two rollers 34, 44 can relative to a vertical axis of the Lifting device H be rotatable (castors). But it could also be used Bockrollen.
  • Each of the two side parts further comprises a rear (second) section 31, 41 (see in particular Fig. 5 ), which is preferably also designed as a profile part with a uniform cross-section, in particular as a rectangular tube.
  • a rear (second) section 31, 41 (see in particular Fig. 5 ), which is preferably also designed as a profile part with a uniform cross-section, in particular as a rectangular tube.
  • At the free ends of the two rear portions 31, 41 of the side parts 3, 4 may each have a second roller holder 35, 45 each have a steering roller 36, 46 may be attached.
  • the castors 34, 44, 36, 46 are movable about the vertical axis of the lifting device H, so that, for example, steering movements can be performed with them.
  • the mobility of the rollers about the vertical axis can be blocked or at least limited by a mechanism. Alternatively, these can also be castors.
  • the front portion 30, 40 and the rear portion 31, 41 of each of the two side parts 3, 4 are over a middle (third) portion 32, 42 (see in particular Fig. 6 ), which is preferably formed as a casting, connected to each other.
  • the casting may be an aluminum (pressure) casting, a cast iron part, or another casting.

  • the Structures 325, 425 for connection to the cross member 5 may be monolithically connected to the remaining central sections 32, 42. It is also possible to attach these to the other sections 32, 42 in order to compensate for tolerances in the assembly of the chassis.
  • cross member 5 can be provided as front portions 30, 40 and as rear portions 31, 41 tubes, can be provided as connecting structures 321, 421 at the central portion 32, 42 of the side parts 3, 4 sockets, which are inserted into the tubes and there are fixed by screws 37, 48 or other fasteners.
  • the sections 30, 31, 40, 41 may be rectangular tubes with the same cross-sectional profile.

  • An advantage of the chassis 2 described with the inter alia, from the sections 30, 31, 32, 40, 41, 42 of the side parts 3, 4 and the cross member 5 constructed chassis 2 is that by a variation of the lengths of the cross member 5 and the sections 30th , 31, 32, 40, 41, 42 of the side parts 3, 4 without much technical effort chassis 2 can be created with other dimensions. By choosing a shorter or longer cross member 5 can narrower or wider chassis 2 are created. A change of the side parts 3, 4 or the master unit 1 is not or not required in principle. By varying the length of the sections 30, 31, 40, 41 of the side parts 3, 4, a larger or smaller projection of the chassis 2 can be achieved via the mast unit 1 to the front or to the rear. The middle sections 32, 42 need not be changed.
