Description

The present invention relates to a freight container for the transport of Goods with means of transport, especially for the transportation of bulk goods Rail vehicles such as freight wagons.

Freight containers are used to transport goods with different Means of transport, for example on roads and rails by truck and freight wagons, and have diverse requirements due to the to fulfill various types of goods to be transported. Basically there is the endeavor to create the largest possible transport area with one as possible small number of different freight containers and means of transport deal with. In this context, in particular, the task arises in a single freight container on the one hand raw products, such as Wood chips as raw materials for the production of chipboard, parquet boards and the like finished wood products, by means of transport in the Transport processing plants into it and then after the Unloading finished products in a simple way, in this case for example in the same freight container with a means of transport Load wood panels and transport them to the end user, taking it What matters most is the loading and unloading process in the shortest possible time carry out and ensure in the cargo container during transport, that the sensitive raw products and finished goods are not damaged. On The basic aim of freight transport is to shorten the Turnaround times through special freight containers and means of transport for the to reach various goods and special loading and unloading facilities.

Especially when transporting bulk goods or granular products in bulk Bulk, such as wood and sawdust, used in the paper industry or used for the production of wooden panels, it is disadvantageous that for Loading and unloading only through relatively small openings Bulkhead doors or through side wall sliding doors and the like Are available and that great opening and closing forces may need to be applied against load resistances.

In addition, it is an extremely complex and not universally applicable System known in which a freight container for unloading the means of transport, for example for lifting or removing from a rail vehicle or a truck, from one equipped with a load handling device Conveyor vehicle, for example one with a mandrel or a fork provided loader, gripped on a side wall and for emptying the Freight container is pivoted or rotated by means of the lift loader, so that the Containers can be emptied through one of the end walls or the roof. In the case of open freight containers, this is even rotated by 180 °. Of The disadvantage is that the freight container must be a special freight container a kind of coupling for coupling the load handler of the conveyor vehicle must have in the side wall. In addition, an extremely powerful Conveyor vehicle can be used, which is able to the cargo container lift and turn or swivel, sometimes up to 30 tons and more.

Especially when unloading those transported on rail vehicles Freight containers is also given the problem that the freight container is not optimally accessible from all sides, since the rail tracks are not accordingly, for example in a large factory where there are tracks, the freight containers are only accessible from one side due to a track wall are.

In view of this prior art, the invention is based on the object of improving a freight system of the type mentioned at the outset, avoiding the disadvantages described, in such a way that a simpler and less expensive unloading of transport means on the one hand and emptying of the freight container on the other while maintaining a universal usability of the freight container in particular with regard to loading and unloading options.

The object is inventively achieved in that the freight container comprises above its bottom at least one mount for a freight container by cross in the unloading load receiving means of a conveyor vehicle and that can be swiveled for emptying the freight container of the floor downward.

Due to the at least one receptacle for a load means of a conveyor vehicle, for example, the forks of a forklift, is a simple unloading of Given means of transport such as rail vehicles and trucks. The Freight containers can thus be gripped by a conveyor vehicle from which Means of transport lifted down and one for emptying the freight container intended location, for example within a factory. The swiveling floor can then be used to cover the entire area Bottom region of the cargo container extending opening is released and so the Freight containers can be emptied very quickly. In addition, the Loading space of the freight container in a manner known per se as before through at least one opening an opening in the side and / or end walls Sliding or hinged doors can be loaded and unloaded with the top open or covered or lockable freight containers also from above. The freight container is thus regarding loading and Unloading options can be used universally.

According to an advantageous embodiment of the invention, the recording is as Hollow body formed, which preferably penetrates the cargo container, so that the receptacle is separated from the loading space of the freight container. In this manner and how the cargo is protected and can be used especially when unloading or Emptying not damaged by the load handler of the conveyor vehicle be what, especially for sensitive goods, for example moisture-sensitive wood chips or finished wood products or food such as cereals and the like is advantageous. According to another advantageous Embodiment of the invention is the freight container with a framework Sidewall posts, these connecting longitudinal and cross members, side and End walls and a floor is built and is taken up by a Cross member of the framework formed, so that complex constructions for Provision of the recording are not required.
