Truck body

The invention relates to a body of a freight wagon, which is preferably designed to be towed by a towing device 5 such as a vehicle, a work machine or the like, and has a bottom, end walls and a roof container for transportable material, essentially coupling means at the first end of the wagon. 10, or at least at one end thereof, to allow movement of the load carriage, such as wheels, rollers or the like. The body of the wagon is arranged in a so-called. 15 having at least two substantially horizontal, longitudinal and transverse interconnected frame beams to which are connected, transversely connected, and substantially vertical 20, frame structures.

The cargo trolley according to the invention is suitable for use in a variety of applications. One typical I I · ·, * · · such application is for example peat extraction.

25 In this case, the peat in the peat field is collected in the field, then the collected peat is transported to the dump site where it is emptied by either the traditional disassembly • · · operation, ie by opening one side of the hopper and tilting the stack. The traditional dismantling procedure mentioned above * · - '··· * has a number of disadvantages, one of which is that the center of gravity of the collection wagon when emptying the container is · 7 ·

. ··. 35 changes. Since the collector truck is usually handled on relatively soft soil, changing the center of gravity f t · often results in the collector truck · ... 'tipping over. Due to the soft soil, the carriage 2 105172 also often tends to sink to one side of the soil during emptying, which is often a very laborious and time-consuming task to re-start the collection car. In addition, the emptying of the collection container of the collector-5 wagon is often vague when using a conventional "tipping" container, so that, first of all, part of the contents of the collection container is easily stuck to its walls. On the other hand, part of the contents of the collection tank is discharged under the hopper, where it is slightly mixed with the ground due to overdrive movement.

In order to overcome the problems associated with the above-mentioned conventional disassembly method, for example, the prior art method of emptying a collection trolley is known from Finnish Patent Application No. 954757 and also the collection trolley used herein. What is new in this solution is that the bottom of the trolley is preferably formed, e.g., by two movable bases relative to the body 20 of the trolley which are moved in opposite directions when viewed in cross section to unload the material in the container on each side of the trolley. •; 'j'; through the holes.

The above solution has proven to be very * ... advantageous, although the bulk of its construction has caused certain printing problems in practice. If the weight of this type of trolley is too high, it will be necessary to limit the volume of the container • * · · ... *, which naturally reduces the efficiency of the work.

On the other hand, U.S. Pat. No. 3,878,911 and Swiss Patent No. 478,020 also disclose frame designs of the type described in the prior art, which on the basis of 3,105,172 are known per se to arrange a so-called self-supporting load carrier body, including at least two substantially horizontal longitudinal and transverse interconnected frame beams to which 5 are coupled, similarly transverse interconnected and substantially upright rack structures. These solutions do not significantly enhance the usability of the said beams either, since, firstly, their focus remains very high on self-supporting, it is not possible to optimize the overall length of the said frames with respect to the load space with sufficiently lightweight constructions, therefore their total mass is relatively s uuri.

The purpose of the truck body of the present invention is to provide a decisive remedy to the above drawbacks and thereby substantially increase prior art. To accomplish this purpose, the truck body according to the invention is essentially characterized in that the frame structures consist of a front wall structure, a roof structure and a rear wall structure, wherein at least:: the rear wall structure is connected to the frame beam by a Y-connection.
