DESCRIPTION:
BRIEF SUMMARY
The invention relates to a vehicle for transporting refuse or the like comprising a container fastened to the vehicle frame and equipped with a foldable rear wall. Since the distances between cities and refuse dumps have become increasingly greater, it is no longer possible for economical reasons to transport the collected refuse in the refuse collecting vehicle directly to the dump. More and more frequently the necessity arises for reloading the refuse still within the respective city or municipal area for transportation to the dump, at one or a plurality of turnover points from the refuse collecting vehicle to refuse transporting vehicles having a larger capacity for transportation to the dump. In this connection it is known, for example, to equip the reloading stations with pressing devices into which the refuse is discharged from the collecting vehicle and where it is compacted with the aid of a press into a transportable container which is then transported to the dump with the aid of a special vehicle. Due to the intensive compacting of the refuse in the transporting vessel, an appropriate unloading device must also be provided at the dump, but such device must be mobile to adjust to the progressive filling of the dump. In addition to the complicated structure of such compactors, this also results in additional costs for the unloading device.
Since, in further development of refuse collecting vehicles, for example in the so-called drum refuse trucks, the collected refuse is already compacted considerably within the collecting vehicle, this provides an opportunity to dump the refuse, already compacted in the collecting vehicle, without noticeable loosening of the refuse, into a transportable container which is open at the top, with the open top of such container then being designed to be closable for transport. This would also be possible, for example, with a high-rim dump truck of corresponding capacity. The difficulty with a simple dump truck having the appropriate capacity is, however, that due to the soft and uneven ground at the unloading location at the dump, the center of gravity of the vehicle may be laterally displaced so much when the bed of the truck is tilted that the vehicle topples over.
It is now the object of the invention to provide a vehicle of the above-defined type which with the largest possible container lengths permitted by motor vehicle safety standards, still permits danger-free and simple dumping of the container contents on soft and uneven ground.
This is accomplished by the invention in that the container is subdivided into two parts transversely to the longitudinal axis of the vehicle; that the front portion of the container is fixed to the vehicle frame; that the rear portion of the container is connected with the vehicle frame so as to be tiltable about a transverse axis disposed in the region of the vehicle end and is in communication with a tilting drive; that a ram plate is disposed within the container so as to cover its inner cross section and is connected with a pushing drive so as to be longitudinally displaceable from the driver's cabin side of the container at least to the region where the container is subdivided. A vehicle of such design permits the use of a container of maximum permissible length and thus maximum permissible capacity for the vehicle. By subdividing the container it is possible, in conjunction with the ram plate which sweeps at least through the front container area, to empty the container, once the rear wall has been opened, with the aid of the ram plate so as to push the volume of refuse disposed in the front container portion in the longitudinal direction until the ram plate has reached the partition area between the front and rear container portion. Now the refuse remaining in the rear portion of the container can be emptied in the usual manner by tilting up the rear container portion. Since in this case only part of the entire container length needs to be tilted, the danger of the vehicle tipping over when the rear container end is tilted u
