Description

TECHNOLOGICAL BACKGROUND OF THE INVENTION

[0001] Today, there are approximately 2800 waste collection centers in France, almost all of which are equipped with loading bays. Each waste collection center has an average of six bays, more than half of which handle bulky and / or heavy waste such as wood, bulky items, or scrap metal.

[0002] It is known to arrange the containers under a loading / unloading dock at the waste disposal site: users can thus tip their waste from the top of the dock into the container in a relatively secure manner.

[0003] Trucks then take the skips, once they are full, to the designated outlets.

[0004] In view of the sustained increases in the cost of diesel fuel and the need to reduce the carbon footprint, the communities that manage waste disposal sites are concerned with optimizing the filling of containers in order to minimize transport costs and thus reduce their operating costs.

[0005] For this purpose, it is common practice to equip containers with compaction devices. Such devices compress the waste inside a container to increase its density.

[0006] For example, counting devices can be arranged in the container at one end and include a wall that presses the waste against a second end.

[0007] Document FR 2 219 088 A2 discloses the preamble of claim 1.

[0008] However, current compaction methods are only effective on light and easily deformable waste such as cardboard, plastic or paper. SUBJECT OF THE INVENTION

[0009] One aim of the invention is to provide a solution enabling the compression of bulky and / or heavy and / or difficult-to-deform waste. BRIEF DESCRIPTION OF THE INVENTION

[0010] The invention thus relates to a container comprising: a roof, a compaction shovel mounted movable relative to the roof between a high position and a low position, means for moving the shovel between its high position and its low position. According to the invention, the means of movement comprise a boom mounted articulated relative to the shovel on the one hand and relative to the roof on the other hand, means for manipulating the boom, the manipulation means comprising at least one group of at least three cylinders, a first end of a first cylinder of the group being articulated on an intermediate zone of the boom, a first end of a second cylinder of the group and a first end of a third cylinder of the group both being articulated on the roof.

[0011] In this way, it becomes possible for a user to arrange even bulky and / or heavy and / or difficult-to-deform waste (plastic, scrap metal, wood, etc.) in such a container, the compaction shovel linked to the boom and the means of manipulating the boom being indeed capable of compacting such waste.

[0012] Optionally, the handling means include two groups of at least three cylinders.

[0013] Optionally, the two groups are arranged on the roof symmetrically with respect to the center of the roof.

[0014] Optionally, the first cylinder is capable of developing a greater thrust than the second or third cylinder.

[0015] Optionally, the first cylinder is arranged between the second cylinder and the third cylinder.

[0016] Optionally, the second and third cylinders are identical.

[0017] Optionally the pendulum has two arms, each arm being articulated relative to the shovel on one side and relative to the roof on the other.

[0018] Optionally the arms are articulated on the roof symmetrically with respect to the center of the roof and / or are articulated relative to the shovel symmetrically with respect to the center of the roof.

[0019] Optionally the rocker arm is articulated on the shovel by means of at least one connecting rod.

[0020] Optionally at least one portion of the balance beam is bent.

[0021] Optionally, the container includes a slide extending between an upper end of the box and the inside of the box to form a slope towards the inside of the box.

[0022] Other features and advantages of the invention will become apparent from the following description of a particular, non-limiting embodiment of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The invention will be better understood in light of the following description with reference to the attached figures, among which: [ Fig. 1 ] there figure 1 is a schematic side view of a waste disposal platform equipped with a container according to a particular embodiment of the invention, one of the container's shovels being in the raised position, [ Fig. 2 ] there figure 2 is a perspective view of the container illustrated in the figure 1 , [ Fig. 3 ] there figure 3 is a perspective view of the container illustrated in the figure 1 , with the container's shovel in the neutral position, Fig. 4 ] there figure 4 is a perspective view of the container illustrated in the figure 1 , the container's shovel being in the lowered position. DETAILED DESCRIPTION OF THE INVENTION

[0024] THE figures 1 à 4 represent a waste disposal site comprising at least one waste disposal platform Q overlooking at least one container 1, also called storage container 1. For example, platform Q is located between 0.2 and 1 meter above a roof 2 of container 1.

[0025] A safety barrier B secures the dock Q so that a user cannot fall into container 1 or be injured by a movement of a compaction shovel of container 1, a shovel which will be described below.

[0026] Container 1 comprises a box 3 consisting of a frame formed of sides, the frame being completely closed at its lower end by a bottom 4. There are four sides. The sides and / or the bottom 4 are made of sheet metal. The sides and / or the bottom 4 are fixed together.

[0027] Container 1 is generally shaped like a parallelepiped. Container 1 extends longitudinally along a first direction X. The base 4 extends parallel to a plane containing the first direction X and a second direction Y orthogonal to the first direction X. A third direction Z, orthogonal to the first direction X and the second direction Y, defines the height of the container 3. Two of the four sides extend parallel to a plane containing the X and Z axes and are hereafter referred to as longitudinal sides. The other two sides of container 3 extend parallel to a plane containing the Y and Z axes and are hereafter referred to as lateral sides. A first lateral side 5 forms or includes a door allowing access to the interior of container 3.

[0028] This allows the container 3 to be emptied when it is taken, for example, to an incineration or recycling plant.

[0029] The box 3 also includes a roof 2 arranged at the upper end of box 1.

[0030] The roof 2 has a base 6 extending parallel to the bottom 4 opposite it. The base 6 is preferably formed of at least one sheet metal plate. The base 6 is fixed to the sides.

[0031] In this case, the base 6 extends over only part of the length of the box 3 (along the first X direction) and over the entire width of the box 3 in that particular section (along the second Y direction). The base 6 thus partially closes the upper end of the box 3. It defines an access opening 7 inside the box 3. This opening 7 is located at one longitudinal end of the box 3.

[0032] Container 1 is also arranged so that the first longitudinal end of caisson 3 is located opposite and below dock Q. Container 1 thus extends orthogonally to dock Q. Opening 7 is therefore located directly below dock Q.

[0033] In this way, a user can throw their waste into container 1 from platform Q, through opening 7.

[0034] Note that the second lateral side 8 (forming the first longitudinal end of the caisson 3) is located opposite the quay Q and opposite the first lateral side 5. Thus, the access door inside the container 3 is located on a side opposite to that associated with the opening 7 and the quay Q.

[0035] The roof 2 also includes a compaction shovel 9 mounted on the roof 2 and more specifically mounted on the upper face 6a of the base 6 (i.e., the face opposite the lower face 6b of the base 6, which is turned towards the inside of the container 3). The compaction shovel 9 is thus fixed to the rest of the container 3.

[0036] The compaction shovel 9 is mounted movably on the base 2 between a high position and a low position.

[0037] The compaction shovel 9 is preferably mounted to rotate between these two positions, high and low, around a shaft 10 extending along an axis A. For example, the compaction shovel 9 is mounted on the base 6 so that the axis A is parallel to the second direction Y. Preferably, the compaction shovel 9 is mounted on the base 6 so that the shaft 10 extends along the edge of the base 6, defining the opening 7.

[0038] It is therefore understood that the compaction shovel 9 is arranged at the first longitudinal end of the caisson 3 while the access door is located at the second longitudinal end of the caisson 3. The access door and the compaction shovel 9 are thus arranged at opposite ends of the caisson 3.

[0039] Preferably, the compaction shovel 9 is shaped as a plate. For example, the compaction shovel 9 is formed from a sheet of metal. The compaction shovel 9 thus has two main faces 9a and 9b extending parallel to a plane containing axis A and an axis B orthogonal to axis A. The compaction shovel 9 has the same thickness or a different thickness than the base 6.

[0040] The roof 2 also includes means for moving the compaction shovel 9 between its high position and its low position.

[0041] The means of movement include a rocker arm 11 articulated on the compaction shovel 9 on one side and on the base 6 on the other.

[0042] More specifically, here, the balance wheel 11 comprises a plate 12 and at least one arm. In this case, the plate 12 is associated with two arms 13 and 14 of the balance wheel 11. The plate 12 and the two arms 13 and 14 are a single piece.

[0043] Optionally, each arm 13, 14 is arranged at one of the lateral ends of the balance wheel 11. The plate 12 thus forms a spacer between the two arms 13, 14.

[0044] Each arm 13, 14 is here bent. Each arm 13, 14 is optionally formed of two connecting rods (which are however preferably in one piece): a first connecting rod 15 extends along an axis C and a second connecting rod 16 extends along an axis D, the axis D being inclined with respect to the axis C. The two arms 13, 14 are arranged identically so that the first two connecting rods 15 extend parallel to each other and to the axis C and that the second two connecting rods 16 extend parallel to each other and to the axis D.

[0045] The plate 12 can also be angled and thus comprise a first part extending between the first two connecting rods 15 parallel to axis C and a second part extending between the second two connecting rods 16 parallel to axis D. Preferably, each part is formed from a plate and, for example, a sheet. Alternatively, the plate 12 may comprise only a single part extending between the first two connecting rods 15 parallel to axis C or between the second two connecting rods 16 parallel to axis D. Preferably, this single part is formed from a plate and, for example, a sheet.

[0046] The two arms 13 and 14 are arranged so that the first connecting rods 15 are articulated at their first end on the base 6 along the same articulation axis E (but in two different areas of the base 6 due to the spacing between the two arms 13 and 14). Preferably, the first connecting rods 15 are articulated on the base symmetrically with respect to the center of the base 6. The first connecting rods 15 are directly articulated on the base 6.

[0047] The two arms 13, 14 are also arranged so that the second ends of the first connecting rods 15 coincide with the first ends of the second connecting rods 16.

[0048] The two arms 13, 14 are also arranged so that the second ends of the second connecting rods 16 are articulated at their second end on the compaction shovel 9 along the same axis F (but in two different areas of the compaction shovel 9 given the spacing between the two arms 13, 14).

[0049] Optionally, the second connecting rods 16 are not mounted directly articulated on the compaction shovel 9 but are directly articulated on connecting rods which are themselves directly mounted articulated on the compaction shovel 9.

[0050] Thus, with regard to the first arm 13, its second connecting rod 16 is mounted articulated at its second end to a first end of a first connecting rod 17 along the axis F, the first connecting rod 17 being itself mounted articulated at its second end on the compaction shovel 9 along an axis G.

[0051] As regards the second arm 14, its second connecting rod 16 is mounted articulated at its second end to a first end of a second connecting rod 18 along the axis F, the second connecting rod being itself mounted articulated at its second end on the compaction shovel 9 along the axis G.

[0052] We note therefore that the axis F of articulation of the rocker arm 11 to the connecting rods 17, 18 is identical for the two connecting rods 17, 18 and that the axis G of articulation of the compaction shovel 9 to the connecting rods 17, 18 is identical for the two connecting rods 17, 18.

[0053] Preferably, the second connecting rods 17, 18 are articulated on the compaction shovel 9 symmetrically with respect to the center of the compaction shovel 9.

[0054] Preferably, the second connecting rods 17, 18 are articulated on the first main face 9b of the compaction shovel 9.

[0055] Axes F and G are parallel to each other here.

[0056] Axes F and E are parallel to each other here.

[0057] At least one of the axes E, F, G is parallel to the second direction Y and / or to the axis A.

[0058] According to another aspect, the roof 6 includes means for manipulating the pendulum 11.

[0059] The handling means here comprise a first group 19 of at least three cylinders and a second group 20 of at least three cylinders. Since the two groups 19 and 20 are identical in this case, the following description of the first group 19 is also applicable to the second group 20.

[0060] The first group 19 comprises three cylinders, namely a central cylinder 21 and two lateral cylinders 22, 23 arranged on either side of the central cylinder 21. The lateral cylinders 22, 23 are, for example, fixed to the central cylinder 21 or removably attached to the central cylinder 21. Preferably, the lateral cylinders 22, 23 are fixed to the central cylinder 21 by being arranged symmetrically with respect to the central cylinder 21.

[0061] Furthermore, the two lateral cylinders 22 and 23 are arranged so that each is articulated at one of their ends to the base 6 along the same articulation axis H (but in two different areas of the base 6 due to the spacing between the two lateral cylinders 22 and 23). Their other ends are fixed to the central cylinder 21. The lateral cylinders 22 and 23 are thus able to extend / retract simultaneously towards the base 6.

[0062] Furthermore, the central cylinder 21 is arranged so as to be articulated at one of its ends on the rocker arm 11 along an articulation axis I. Its second end is fixed to the lateral cylinders 22, 23.

[0063] Preferably, the central cylinder 21 is articulated on an intermediate zone of the rocker arm 11, outside the first ends of the first connecting rods 15 and outside the second ends of the second connecting rods 16. Preferably, the intermediate zone is the angled zone 24 of the rocker arm 11 (i.e., the portion of the rocker arm 11 defined by the bends of the two arms 13, 14, and the possible bend of the plate 12). Preferably, the central cylinder 21 is articulated at the second end of the first connecting rod 15 (which coincides with the first end of the second connecting rod 16). The central cylinder 21 is thus able to extend / retract in the direction of the compaction shovel 9.

[0064] Axes I and H are preferably parallel to each other.

[0065] At least one of the axes E, F, G is parallel to at least one of the axes I and H.

[0066] At least one of the axes I and H is parallel to the second direction Y and / or to the axis A.

[0067] In this case, all axes A, E, F, G, H, I and Y are parallel to each other.

[0068] It is therefore understood that the lateral cylinders 22, 23 are mounted in reverse with respect to the central cylinder 21 so that they extend / retract opposite the base 6, unlike the central cylinder 21 which extends / retracts in the direction of the rocker arm 11.

[0069] The cylinder assembly is such that the rods of the two lateral cylinders 22, 23 and the central cylinder 21 retract and extend parallel to each other (but in opposite directions as seen above).

[0070] The pressurized fluid supply to the cylinders is ensured by at least one fluid supply source and at least one associated distribution circuit (not shown).

[0071] The two lateral cylinders 22, 23 are preferably identical. The two lateral cylinders 22, 23 thus develop the same thrust. Preferably, the central cylinder 21 develops a thrust equal to the sum of the thrusts of the two lateral cylinders 22, 23.

[0072] For example, the central cylinder 21 develops a thrust of at least 15 tonnes and preferably at least 20 tonnes.

[0073] For example, each of the lateral cylinders 22, 23 develops a thrust of at least 5 tonnes and preferably at least 10 tonnes.

[0074] Preferably, the group of three cylinders develops an overall thrust of at least 40 tonnes and preferably at least 45 tonnes.

[0075] If we consider the two groups of cylinders, we can therefore understand that: The various lateral cylinders 22, 23 are arranged so that their first ends are all articulated on the same articulation axis H (but in four different areas of the base 6 due to the spacing between the various lateral cylinders 22, 23). Preferably, the first ends of the lateral cylinders 22, 23 (i.e., the free ends of the rods of the lateral cylinders 22, 23) are articulated symmetrically with respect to the center of the base 6. The lateral cylinders 22, 23 are all capable of extending / retracting simultaneously towards the base 6. The various central cylinders 21 are arranged so that their first ends are all articulated on the same articulation axis I (but in two different areas of the rocker arm 11 due to the spacing between the various central cylinders 21).Preferably, the free ends of the central cylinders 21 (i.e., the free ends of the rods of the central cylinders 21) are articulated symmetrically with respect to the center of the balance wheel 11. Typically, the first central cylinder 21 is articulated on the first arm 13 (at the junction between the two connecting rods 15, 16 of the first arm 13) and the second central cylinder 21 is articulated on the second arm 14 (at the junction between the two connecting rods of the second arm). Furthermore, the various central cylinders 21 are all controlled simultaneously. The central cylinders 21 are all capable of extending / retracting simultaneously in the direction of the balance wheel 11.

[0076] Preferably, the base 6 includes longitudinal members 25 and cross members 26 to reinforce the base 6.

[0077] Preferably, the articulation zones of the first connecting rods 15 on the base 6 are located on the longitudinal members 25 or the cross bars 26. Preferably, the articulation zones of the first ends of the lateral cylinders 22, 23 on the base 6 are located on the longitudinal members 25 or the cross bars 26.

[0078] Preferably, the container 1 has a slide 27 to facilitate the compaction of waste. This slide 27 is here associated with the first longitudinal end of the container 3. The slide 27 is directly formed by the second side wall 8 (and possibly one or more other adjacent sides and / or the bottom 4) and / or one or more additional walls attached to the second side wall 8 (and possibly one or more other adjacent sides and / or the bottom 4).

[0079] The slide 27 preferably includes at least a first zone forming a slope 28 towards the inside of the box 3.

[0080] Such a slope 28 makes it easier for waste to fall inside the container 3, preventing waste from accumulating at the level of the second lateral side 8.

[0081] This would make compacting the waste more difficult.

[0082] Preferably, the slope 28 extends from the upper end of the caisson 3 to the inside of the caisson 3 towards the first side 5 and / or the bottom 4 of the caisson 3. Preferably, the slope 28 is not flat. The slope 28 is thus curved towards the bottom 4 and / or the second side 8. The slope 28 thus forms an arc. Preferably, the curvature of the slope 28 follows the rotation path of a free end of the compaction shovel 9. Preferably, the slope 28 extends from the upper end of the caisson 3 to the level of the articulation shaft 10.

[0083] The slide 27 preferably includes at least a second zone 29 extending successively to the first zone to connect the first zone to the bottom 4 of the box 3. Preferably the second zone 29 extends in a straight line between the first zone and the bottom 4 of the box 3.

[0084] This second zone 29 advantageously prevents waste from accumulating up the slope. This frees up opening 7.

[0085] Because the second zone 29 starts approximately at the level of the tree 10, this limits the risk that a rise of waste will hinder the rotation of the compaction shovel 9.

[0086] The second zone 29 extends, for example, parallel to the second lateral flank 8 and / or vertically.

[0087] The slide 27 thus described is fixed in container 1 and shaped in part into an arc of a circle which follows the trajectory of the end of the shovel, in order to guide the waste being compacted / compacted towards the rear of container 1 and to prevent the compaction shovel 9 from falling on a wall of non-compactable and / or uncompacted waste.

[0088] In operation, container 1 is positioned such that compaction shovel 9 is in the raised position as illustrated in the figure 1 and to the figure 2 This raised position is also known as the "loading position". In this position, opening 7 is freely accessible, allowing a user to unload their waste into container 1.

[0089] In this position, the rods of the various cylinders are fully retracted or at least partially retracted. The angled area 24 is directed towards the base 6 by being arranged behind the axes E, F, G and A and in front of the axis H. From front to back (the front being defined as the part of container 1 closest to the platform Q and the back as the part of container 1 furthest from the platform Q, the first longitudinal end of the box 3 is thus in front of the container 1 and the second longitudinal end of the box 3 is thus in front of the container 1), we find successively the following axes: A, G, F, E, I and H.

[0090] In this position, the compaction shovel 9 extends above the base 6.

[0091] In this position, the compaction shovel 9 extends: parallel to the third direction Z and upwards (in the opposite direction from the inside of box 3), the compaction shovel 9 is then arranged orthogonally to the base 6. Optionally then, axes A and B are orthogonal to the first direction X and axis B is parallel to the third direction Z.

[0092] Or inclined relative to the third direction Z, outwards from the opening 7 and towards the second longitudinal end of the box 3.

[0093] In all cases, container 1 is then open since the opening 7 is not covered by the roof 2 and in particular by the compaction shovel 9: a user can thus tip waste into container 1 via the opening 7.

[0094] It is noted that the opening 7 is particularly large in size since the compaction shovel 9 defines with the base 6 an angle optionally between 80 and 100 degrees, and for example between 85 and 95 degrees, and for example between 88 and 92 degrees and is for example 90 degrees, while being arranged outside the box 3. This greatly facilitates the loading of waste into the container 1 even if the waste is large in size.

[0095] If the waste needs to be compacted, the compaction shovel 9 must be lowered into its lowest position. To do this, the hydraulic cylinders are activated to lower the compaction shovel 9. This action can be performed automatically (for example, at regular intervals, when new waste is detected being dumped into container 1...) or manually by a waste disposal site operator.

[0096] Preferably, the dimensions of the compaction shovel 9 are such that it is not in contact with the longitudinal sides during its movement between its high position and its low position.

[0097] This avoids friction between the compaction shovel 9 and the caisson 3 which could damage them.

[0098] Preferably, the compaction shovel 9 passes through a neutral position, visible to the figure 3 , during its movement from high position to low position (and vice versa).

[0099] For this purpose, between the raised and neutral positions, only the rods of the central cylinders 21 are extended. The rods of the lateral cylinders 22 and 23 are optionally not extended and are therefore in the same position relative to the associated cylinder body whether in the raised or neutral position (and the intermediate positions in between). Optionally, the rods of the central cylinders 21 are fully extended or at least partially extended in the neutral position.

[0100] In this position, the angled area 24 is directed towards the second longitudinal end of the box 3, being arranged behind the axes E, F, G and A and in front of the axis H. From front to back, the following axes are thus successively found: G, F, A, E, I and H. If the plate 12 has a part extending between the two second connecting rods 16 of the balance wheel 11 then this part extends here parallel to the base 6 and optionally parallel to the first direction X.

[0101] In this position, the compaction shovel 9 extends in line with the base 6. The compaction shovel 9 thus extends at the level of the base 6. The compaction shovel 9 is more particularly arranged parallel to the base 6 and optionally parallel to the first direction X and optionally parallel to the part of the rocker 11 extending between the two second connecting rods 16.

[0102] In this position, container 1 is then closed. Indeed, the compaction shovel 9 then covers the opening 7. More precisely, the compaction shovel 9 forms a junction between the base 6 and the first longitudinal end of the caisson 3.

[0103] In this position, the frame is then completely closed at the top end by the roof 2. The neutral position is thus also called the "transport position or security position (especially against theft)".

[0104] In this position, the first main face 9b of the compaction shovel 9 is turned towards the outside of the caisson and its second main face 9a is turned towards the inside of the caisson 3.

[0105] The compaction shovel 9 continues its movement towards its lowered position visible at the figure 4 also also called "compaction position".

[0106] Between the neutral and lowered positions, only the rods of the lateral cylinders 22 and 23 are extended. The rods of the central cylinders 21 are optionally not extended and are therefore in the same position relative to the associated cylinder body whether in the lowered or neutral position (and the intermediate positions in between). Optionally, the rods of the lateral cylinders 22 and 23 are fully extended or at least partially extended in the lowered position.

[0107] In this position, the angled area 24 is directed upwards (in the opposite direction to the inside of the box 3) by being arranged behind the axes A, G and F and in front of the axes E and H. From front to back, we thus find successively the following axes: F, G, A, I, E and H.

[0108] In this position, the compaction shovel 9 extends below the base 6.

[0109] In this position, the compaction shovel 9 extends: parallel to the third direction Z and downwards (inside box 3), the compaction shovel 9 is then arranged orthogonally to the base 6. Optionally then, axes A and B are orthogonal to the first direction X and axis B is parallel to the third direction Z.

[0110] Or inclined relative to the third direction Z, towards the inside of the opening 7 and in the direction of the first longitudinal end of the box 3 or the second longitudinal end of the box 3.

[0111] In all cases, the compaction shovel 9 extends inside the caisson 3.

[0112] The compaction shovel 9 is thus engaged in the box 3, which allows it to compact the waste.

[0113] It is therefore understood that the opening of box 3 allows the compaction shovel 9 to be able to tilt from its high position to its low position to fit inside box 3.

[0114] It is noted that compaction is particularly important since the compaction shovel 9 then defines with the base 6 an angle optionally between 80 and 100 degrees, and for example between 85 and 95 degrees, and for example between 88 and 92 degrees and is for example 90 degrees, while being arranged inside the box 3.

[0115] To go from the low position to the high position, you simply need to follow the reverse path of what has been described.

[0116] Preferably, if compaction of the waste is desired, the movement of the compaction shovel 9 is continuous between its upper and lower positions without stopping at the neutral position. Similarly, the return of the compaction shovel 9 to its upper position is continuous without stopping at the neutral position.

[0117] Preferably, if you only want to close box 3, you can bring compaction shovel 9 into its neutral position and hold it in that position.

[0118] This makes it easier to move container 1.

[0119] The container 1 described above has a very large opening when the compaction shovel 9 is in its raised position.

[0120] This allows even large-sized waste to be tipped into container 1 in a way that is safe for the user.

[0121] Container 1, as described, allows a large range of motion for the compaction shovel 9.

[0122] The actuation means advantageously allow the compaction shovel 9 to be able to perform such a movement while themselves presenting a relatively limited movement.

[0123] Of course the invention is not limited to the embodiment described and alternative embodiments can be made without departing from the scope of the invention as defined by the claims.

[0124] The compaction shovel may include longitudinal beams and / or crossbars for reinforcement. The base may not include longitudinal beams and / or crossbars.

[0125] The rocker arm may be articulated in only one zone (and not two as indicated) on the base on one side and / or on the compaction shovel on the other, or it may be articulated in more than one or two zones on the base on one side and / or on the compaction shovel on the other.

[0126] The pendulum may only be manipulated in one zone (and not two as indicated) by the manipulation means or may be manipulated in a greater number of zones than indicated.

[0127] Although here the container is located at the bottom of a waste disposal site dock, the container could be arranged at the bottom of a dock in a company, a logistics warehouse or other... or be arranged at the level of a dock or in an intermediate part between the level of the dock and under the dock.

[0128] The intermediate zone of the balance wheel may not be angled.
