All wholesale and retail companies and many manufacturing companies collect the waste in transportable containers, which are made available to the users of specialized companies. These companies drive these containers for a certain fee to the landfill. The containers are usually roll-off containers according to DIN 30722. Depending on their size, these containers have a capacity between 10 and 40 m ^{3 of} waste. In most cases, the content is packaging material. This takes a large volume, but has a low weight. Consequently, the capacities of the containers are not used economically because the large volume of waste requires short emptying intervals.

Such a device is for example from the DE 43 15 504 known. This publication relates to a piston-cylinder unit for moving a shield in the collecting container.

Other rights exist for devices for compacting refuse within a household refuse collection vehicle. From the DE 34 47 814 For example, an unloading device for a refuse collection device is known which moves a hydraulic cylinder driven pressing plate within the loading space of a refuse vehicle. These rights include presses for compressing the waste by means of a horizontally displaceable in the container stamp.

The common systems is common that they are in a specially trained Containers / Containers or transport vehicle arranged compression devices. All systems also have in common that in relation to the Containers / Containers movable compression device has a press plate, the above a press plate actuator introduced from a rest position in the collection and in a Compression position is converted to perform the compression. To absorb the forces occurring during compression, the Clippings be specially designed, for example, provided with stiffeners be to absorb the forces occurring during compression to be able to. Especially for larger amounts of waste Therefore, such devices are not universally applicable.

The in their entirety with 100 designated mobile waste press 100 is in a commercial dumpster 200 arranged.

The dumpster 200 has in the present case a container length of 7200 centimeters, a clear container width of 2320 centimeters and a height of 2228 centimeters. It consists of two opposite and longitudinally extending container side walls 202 . 204 and one transverse to them at the rear end between the container side walls 202 . 204 extending container back wall 206 to form a closed container interior. At the front end is the dumpster 200 closed by two hinged double doors (not shown in detail).

The mobile waste compactor according to the invention 100 consists of a top frame 102 , which is composed of several C-profiles. On this frame 102 are pivotally extending in the longitudinal direction parallel to each other and over the frame 102 spaced side walls 104 . 106 attached. At the rear end is on the frame 102 one like the side walls of the rack 102 downwardly projecting rear wall 108 fastened, extending across the side walls 104 . 106 extends. At the front end of the trash compactor 100 is the back wall 108 opposite a slider 110 arranged, which is also from the frame 102 diagonally down and between the side walls 104 . 106 extends.

How out 2 can be seen, is the distance of the slider 110 from the back wall 108 over two on the top of the frame 102 fastened, in the longitudinal direction of the waste press 100 frightening hydraulic cylinders 112 adjustable to reduce the overall length of the transportable waste press for transport. pushrods 114 connect the rear ends of the hydraulic cylinders 112 . 114 with the slider 110 ,

On the inside of the slider 110 is about four telescopic cylinders 116 the press plate 120 the compression device arranged. This press plate 120 is used to compress the waste by extending the telescopic cylinder 116 in through the side walls 104 . 106 , the back wall 106 and the press plate 120 above the container floor 208 Retracted compression space retracted. When compressing the press plate 120 from the in the 2 shown starting position in the in 4 shown end position axially along the longitudinal direction of the waste container 200 pushed. The volume of the compression space is reduced to one third of the original volume.

At the upper ends of the hinged side walls 104 . 106 are equally spaced pairs of opposite angle profiles 122 . 124 arranged. The angle profiles 122 . 124 have a substantially L-shaped geometry; every angle profile 122 . 124 Each has a cross leg facing each other in the installed position and a longitudinal leg extending essentially transversely to the transverse legs and parallel to each other. At the outer end of the longitudinal leg, an opening is formed, in which a on the frame 102 provided bolt 126 . 128 intervenes. The transverse legs of the angle profiles 122 . 124 also have openings for receiving rotary pins 130 . 132 on. Between the transverse legs of the angle profiles, which are to be projected towards one another in the installation position 122 . 124 are four formed as a hydraulic cylinder transverse cylinder 134 arranged, extending between the rotary bolt 130 . 132 extend. By extending the cross cylinder 134 become the sidewalls 104 . 106 around the bolts 126 . 128 pivoted and transferred to the vertical compression position, which is also the transport position.

To a bending of the slider 110 and to avoid the guides under the high pressing pressure during compression becomes the slider 110 automatically locked at its lower edge after entering the compression space. How very good of the 5 and 6 seen are on the inside of the slider 110 two locking arms projecting substantially parallel to one another 142 pivotable on the inside of the slider 110 attached. Between these locking arms 142 extends as a hydraulic cylinder trained clamping cylinder 145 with which the locking arms 142 are pivotable about their pivot points. The locking arms 142 have outside on their front ends locking lugs 146 on that in openings 150 in the side walls 104 . 106 interlock positively to the slider 110 form-fitting with the side walls 104 . 106 for performing the compression process. Thus, the forces resulting from the compression of the slider 110 and the back wall 108 in the side walls 104 . 106 directed. The lock between the slider 110 and the side walls 104 . 106 is by retracting the hydraulic cylinder 145 automatically resolved.

In the present embodiment, the rear wall 108 positive locking via a similar locking with the side walls 104 . 106 connected. This lock transfers to the back wall 108 acting pressing pressure as a longitudinal force on the side walls 104 . 106 and on the rack 102 ,

The function of the mobile waste press 100 will now be described by way of example when compacting the contents of a 7.2-meter waste container. During the truck transport there is the mobile waste press 100 in the transport position with retracted telescopic cylinders 116 retracted hydraulic cylinders 112 and extended cross cylinders 134 ,

The press plate 120 is inserted into the compression space in the outer end position and the pivotable side walls 104 . 106 are in the vertical transport position.

The mobile waste press 100 is now using a specially designed crane for accurate positioning of the waste press 100 above the waste container 200 positioned and the wings of the container door at the front end are opened.

The Press is then centered on the special vehicle above the Container positioned.

Before lowering the waste press 100 in the waste container 200 become the sidewalls 104 . 106 by retracting the transverse cylinder 134 swung outwards. The waste press is then lowered from that until the lower edge of the side walls 104 . 106 a few inches below the top of the waste container 200 located.

The transverse cylinders 134 are then retracted until the lower edges of the side walls 104 . 106 the insides of the container side walls 202 . 204 touch. The waste press 100 is now lowered so far until the side walls 104 . 106 and the back wall 108 on the container floor 208 seated. By slopes at lower ends of the side walls 104 . 106 is doing on the container side walls 202 . 204 adjacent waste is pushed into the compression space. Thus effectively jamming the waste press is avoided when lowering.

The side walls 104 . 106 are then by extending the transverse cylinder 134 pivoted into the vertical compression position and compress the waste over the entire container length of originally 2.32 meters (= container width) to 1.4 meters.

In this position push the axially extending hydraulic cylinder 112 the slider 110 about 1.5 meters into the waste container 200 into the compression space above the container floor 208 to build.

By extending the telescopic cylinder 116 the garbage in the compression room is compressed to about 1.4 meters wide, 1.68 meters long and 2.2 meters high. This completes the compression process.

After compression, the sidewalls pivot 104 . 106 in the inclination and the telescopic cylinder 116 pull the press plate 120 back. The waste press 100 gets out of the waste container from the special crane 200 lifted and all power cylinders bring the press plate 120 , the slider 110 and the side walls 104 . 106 in the transport position for removal of the press.

The featured mobile press is particularly economical, because the Compacting costs only a fraction of the removal costs. The actuators The press are preferably hydraulically driven. Finally is the press is preferably designed so that the collecting container during the Inserting the press while the compacting and while the lifting is exposed to no mechanical stress. The Press is thus universally usable in each storage container, in particular for all Waste container.
