Definitions

  • the invention relates to a material handling vehicle, in particular portal-like high-floor industrial truck, with wheels having chassis and with a hoist for between the wheels of the chassis recordable and mit211bare loads, such as containers or the like.
  • Known industrial trucks of the aforementioned type are known e.g. Straddle.
  • Portal stackers can pick up a container, transport it to a container warehouse and deposit it at a predetermined location. At this point, the straddle carrier can stack up to four containers one above the other, making better use of the area of a container warehouse.
  • a known per se forklift vehicle of the aforementioned type ie a gantry forklift, transport individual containers of a container stack out of the container store and deliver them to a loading facility.
  • the storage density of a container warehouse is further limited by the formation of container-stacked lanes in which semi-trailer transporting road transport tractors of Containers can run. These lanes in a container warehouse are relatively narrow and can no longer be traveled by a gantry forklift with a container.
  • the invention has for its object to provide a material handling vehicle, which can accommodate containers such as a portal stacker automatically, but also with the recorded container the narrower lanes between stacked containers, which are provided for passage with trucks for the transport of containers ride can.
  • the industrial truck according to the invention with a container taken on the narrow lanes for trucks or other road vehicles, so-called “truck lanes”, driven in a container storage.
  • trucks lanes driven in a container storage.
  • This is possible because it has at least one adjusting device for changing or adjusting the distances between the contact points of the wheels.
  • An inventive material handling vehicle thus has a device with which the dimensions of its footprint can be changed or adjusted.
  • the dimensions of a container taken up by the industrial truck in particular the container width, determine the width of the alley in a container warehouse, which can still be traversed by the industrial truck with recorded container.
  • the industrial truck according to the invention is adapted by means of the adjusting device to the dimensions of a recorded or male container.
  • the contact points of the wheels when they are changed in terms of their distances, also influence the outer dimensions of the industrial truck, ie, when the distance between the Change points of the wheels changes, change the dimensions of the industrial truck.
  • the industrial truck according to the invention can be used and driven like a conventional portal stacker.
  • the invention offers the advantage of truck lanes, the so-called "truck lanes", which could not be used in existing container storage of gantry trucks so far, now to use for driving through the industrial truck according to the invention.
  • the previously required for portal stacker sufficiently wide lanes in a container storage can be omitted, making the useable for the stacking of containers storage space is greater.
  • the container warehouse is more economical to operate and use.
  • Containers are internationally standardized containers with different container lengths and container heights. They serve the transport of goods by several means of transport without repacking the load.
  • a hoist the loading bridge sets the detected container either from under the loading bridge on a transport vehicle, which then moves the container using the so-called “truck lanes” in the container storage, or the container placed under the loading bridge is a portal stacker, a so-called “ Straddle carrier ", picked up and stacked in the container storage.
  • transport vehicles to transport the container from the loading bridge to the container warehouse and in the container warehouse itself has the advantage that can be stacked on the available container area a larger number of containers.
  • the tramlines can be narrower, on the other hand, a gantry crane can be used in the warehouse, with the higher container stack can be formed.
  • the disadvantage here is the temporal dependence of both the loading bridge and, in the container storage, of the gantry crane.
  • the industrial truck according to the invention is able to use the narrow lanes, the "truck lanes", in a container warehouse, into which containers are stacked with a gantry crane. Since the industrial truck according to the invention can automatically pick up, transport and deposit a container, the advantages of a warehouse operated with straddle carriers can be combined with those of a container warehouse that is operated by lorries, or so-called “trailers", without having their disadvantages take.
  • the achievable storage density corresponds to that of a serviced with gantry cranes bearing, but the time dependence is no longer given at the loading bridge and the gantry crane with advantage.
  • the adjusting means for changing the suspension length is also useful to move predetermined wheels of the chassis by means of the adjusting device so that their Aufstsfrag reach an area in front of or behind the container, so that the width of the industrial vehicle is less than the width of the male or container to be transported.
  • This is realized in the industrial truck according to the invention characterized in that it has at least one second adjusting device for changing the chassis width.
  • the first and the second adjusting device for changing the chassis length and the chassis width at the wheels having the suspension combined with each other.
  • the chassis on a vehicle frame arranged subframe each having an axis associated wheels. At least one wheel of a subframe associated wheels is designed as a steerable steering wheel. Preferably, each wheel is a steering wheel, so that the industrial truck according to the invention can be flexibly controlled and driven as a four-wheel drive vehicle with four-wheel steering, to handle containers.
  • Each steering wheel is steered in a turntable, wherein each turntable is rotatably mounted on the respectively associated subframe.
  • Steering movements of the individual fifth wheel can be carried out with corresponding controls of the industrial truck, for example hydraulically or electrically.
  • Each wheel of the industrial truck can have its own drive, as it is also known and common in gantry trucks.
  • a first adjusting device is realized in the industrial truck according to the invention in a structurally inexpensive and therefore simple and reliable execution characterized in that each subframe is held longitudinally displaceable guided on predetermined parts of the chassis frame.

Between subframe and longitudinal beam is thus a Straight guide before, which is realized in that the guide receptacle is arranged in the subframe breakthrough, the inner wall is designed as a guide of the subframe to the predetermined part of the chassis frame, the longitudinal spar.
  • any other form of a linear guide is possible, which allows a change in distance between the supported on supporting parts of the chassis subframes.
  • each subframe has sections which are pivotable about a vertical axis relative to each other, wherein at each section at least one steering wheel of the wheels is arranged, which is associated with an axis of the respective subframe are.
  • each subframe is formed in two parts. The about a vertical axis relative to each other pivotally movable portions of each subframe make it possible to hold a fixed portion of the subframe to the predetermined leading part of the chassis frame the longitudinal spar. By a pivoting movement of the other, movable portion of each subframe about a vertical axis, then the distance of the arranged on the pivotable portion wheel can be compared to the wheel located on the fixed portion change.
  • the gauge of the industrial truck according to the invention is thus adjustable or variable.
  • This has the advantage that with the vehicle according to the invention possibly narrower lanes between container stacks can be traveled in a container storage.
  • the vehicle has with advantage to the container asymmetrically running lanes, of which a first track of the wheels of the two subframe of the chassis runs as a fixed track next to the container.
  • a second lane passes through the movable portions of the subframe as a "loose track” such that the wheels of these movable sections of the subframe can stand in front of or behind the container.
  • the outer edge of the vehicle lies in one plane with an outer surface of a container.
  • the axis of each wheel located on the movable portion of the subframe is perpendicular to the direction of travel. The direction of travel corresponds approximately to the orientation of the longitudinal axis of a container.
