Abstract

The refuse containers (24) are picked up by the lifting arms (23) from in front of the vehicle and are lifted over the cab roof to tip into the collecting bin. The support frame for the lift and tilt arms is mounted on the chassis behind the cab and extends over the roof of the cab to the pivot points at the front top edge of the cab. The arms are hydraulically powered. The lift control holds the container upright until it reaches the tipping position. The double joined lift arms are controlled to keep the height to a min. over the cab. The containers are tipped into a collecting hopper (10) from where the refuse is pressed into the main part of the vehicle.

Description

The invention relates to a vehicle for picking up and transporting of waste with one on the vehicle behind arranged in the driver's cab, on his Cab end has a fill opening, and with a pair of swivel arms that with a pick-up and tilting device to accommodate at least one in front of the front of the vehicle's standing waste container is and the waste container picked up via the cab moved away and in the area of the filling opening of the Collection container emptied behind the cab, according to the preamble of claim 1.

Vehicles of this type, so-called overhead loaders, are known for example from DE-A-11 82 592 and DE-A-11 42 311. A variant is also from US-A-4 096 959 known, in which instead of a pair of arms only one swivel arm arranged on the side of the vehicle is provided, the one running transverse to the axis direction of the vehicle Crossbar for receiving the waste container. The Swivel arm pair or the single swivel arm are either articulated on the vehicle frame behind the cab and are here arched or bow-shaped (DE-AS 11 82 592, DE-AS 11 42 311) or the pair of swivel arms is in three parts trained and also behind the cab on the upper edge of the collecting container articulated (DE-AS 12 26 053). Of the The advantage of a so-called overhead loader is that the waste bins in the front area and thus in the visible area of the driver can be included. The known vehicles However, this type has the serious disadvantage on that for pivoting and emptying the recorded Waste container a considerable amount of space above the Vehicle is needed in the urban areas is often not available, be it that tram overhead lines, Telephone lines, but also low tree branches are present that hinder the pivoting process.

US-A-3 140 788 and US-A-3 167 195 are overhead loader vehicles known in which the collecting container with the vehicle can neither be moved nor swiveled is fixedly connected. The trained as a pair of swivel arms The loading device is in the upper area stored on the collection container, so that from the loading process to keep the resulting loads away from the vehicle frame. This results in a complex construction for the collection container, which is training as a swap body does not allow.

A refuse collection vehicle is also known from EP-A-0 235 784, that is a detachable container connected to the vehicle and a pressing device firmly connected to the vehicle for filling the collecting container, but in which the Feed the press device provided swivel arm pair in disadvantageously at the bottom of the vehicle frame behind the cab is articulated and bow-shaped.

The invention has for its object a vehicle to train the type described above so that a clean Emptying is caused by the on the vehicle the predetermined permissible Clearance profile even when swiveling and emptying a waste collection container only slightly exceeded becomes.

This object is achieved according to the invention by the one in claim 1 specified means solved. By the arrangement of the swivel bearing of the swivel arm pair in upper front area of the cab, especially one lowered cab, arise compared to the previously known Systems much shorter swivel arms, which is inevitable to reduce the necessary space for performs the swiveling process in the area above the cab. Here, however, the cab doors remain free, so that Unrestricted access is possible at all times. Through the Arrangement of a separate carrier, who also carries the rotary actuator, is constructive perfect connection possible without the deductibility of the Affect container. This arrangement has the advantage that the necessary rigid connection between vehicle chassis and carrier not by others Internals, especially not affected by the engine mount becomes. However, this embodiment allows it on the other hand, the carrier up to beyond the cab extend so that neither the all-round view from the cab free access to the cab through the swivel arms and the wearer is impaired.

In a further advantageous embodiment of the invention provided that on the carrier locking means for fixed Coupling of the collecting container are arranged. Such Locking means, for example, arranged on the carrier Pins and / or hooks can be formed in corresponding recesses in the front area of the collecting container intervene, the carrier is achieved on the one hand and the collection container, on the other hand, essentially one in itself form rigid unit, so that practically none, at least no disturbing relative movements between the collection container and the one protruding into it through the filling opening tubular extension of the hopper occur can. The locking means are expedient with actuating means, for example in the form of hydraulic cylinders or the like. Furthermore, the docked Collecting container due to its weight part of the tipping moment in the area of the articulated attachment point on what to relieves the load on the vehicle chassis in this area.

In a further advantageous embodiment of the invention provided that the drive means for the Press of the hopper stored and the ram guided is. Since the carrier anyway as a practically rigid unit must be trained results from this measure a distortion-free guidance of the press ram.

In a particularly advantageous embodiment of the invention it is provided that the carrier is designed as a box structure is, the hopper and the side walls Are part of the load-bearing structure. This arrangement has the advantage that a rigid Construction is created that both the load when Operation of the swivel arm pair as well as the load when Pressing is able to record.

In a further embodiment of the invention, that the hopper ends up in side walls, which are essentially across the cab extend to the front area. This arrangement has the Advantage that this when swiveling the waste container is already shielded from the side before its emptying point, so that with dusty contents a dust leak under Wind exposure is reduced to a minimum.

In a further embodiment of the invention it is provided that a guide for at the upper edge of the two side walls a sliding cover is provided. Since the invention Design of the swivel arm pair allows this without waste container so far over the hopper swing back that its free ends below The arrangement provides the upper edge of the collecting container a cover the possibility in pure driving, for example, in the field of application or for recording and Settling locations for the detachable collection container, the whole Cover arrangement and so against weather influences shield. It is useful here if the back End of the guides forms a swivel cover. This creates the free space above the hopper enlarged for the emptying process and at the same time the The hopper is still partially shielded without the Free space for the emptying movement is impaired. Even during the collection operation, heavy rainfall can occur at least the area above the hopper in each case are temporarily shielded by the cover, so that an entry of rainwater into the collection container Minimum is reduced.

In a further advantageous embodiment of the invention provided that the carrier by means of a three-point support is attached to the vehicle chassis, whereby, based on the vehicle's longitudinal axis, two side-by-side attachment points are firmly connected to the vehicle chassis and the third attachment point articulated at a distance from it is connected to the vehicle chassis. This arrangement has the Advantage that the rigid and rigid with the vehicle chassis carriers to be connected nevertheless the twist of the Vehicle chassis around the longitudinal axis is not affected. It is particularly useful here if the articulation of the third attachment point in the area of the longitudinal central axis the vehicle chassis is arranged so that this articulation point practically none when the vehicle chassis is twisted Executes transverse movements. It is particularly useful here when the two rigid attachment points in the the cab adjacent area are arranged while the third Fastening point at a distance from it towards the rear of the vehicle is arranged. Another advantage of this three-point support consists in the fact that also in the Operation initiated via the waste containers to be handled Tipping moment is reliably recorded.

In a particularly advantageous embodiment of the invention provided that with the pair of swivel arms around a horizontal Axially rotatably connected pick-up and tilting device for the waste container with at least one drive means is connected to the pair of swivel arms that during the waste container connected to the receiving and tilting device of the swivel path extending over the cab in about vertically aligned and controllable means for Tilting the received waste container are provided.

This ensures that from the waste container nothing falls out or flows out during the swiveling process can, so that the tilting of the received waste container only immediately above the filling opening of the collecting container takes place and thus not only reduces the drop height, but also a targeted and clean emptying for the environment is guaranteed. The drive means can be mechanically formed, in which by means of a transmission linkage via the swivel drive of the swivel device generated pivoting movement of the pivoting device in the same direction on the lifting and tilting device with mechanical Funds can be transferred. The mechanical coupling takes place in such a way that the pivoting movement the pick-up and tilting device with regard to the pivoting speed parallel, with regard to the swivel direction is opposite. For geometrically more complex ones Swiveling devices, in particular in the case of bow-shaped or angled swivel arm pairs is one such mechanical Coupling is relatively complex and leads to a Increase in weight, so that here preferably a hydraulic Drive means is to be provided that immediately the receiving and tilting device acts, in which the Control depending on the swivel angle of the swivel device via a correspondingly controlled supply and discharge the hydraulic fluid.

In an embodiment of the invention it is therefore provided that the drive means is formed by at least one oil motor is connected to the receiving and tilting device is. By regulating the supply and removal accordingly the hydraulic fluid can do the desired relative movement between the receiving and tilting device on the one hand and the pivoting device on the other hand for retention vertical alignment of the waste container will.

In another embodiment of the invention, that the drive means by at least one with the pivoting device connected hydraulic cylinder is formed the preferably via a transmission linkage with the recording and tilting device is connected. Hydraulic cylinder are simpler and have the advantage that they run in parallel on the corresponding parts the swivel device, for example the swivel arms, can be attached. Especially when the swivel device Swivel angle of 100 degrees and more from the Cover the intake position to the emptying position must, such a hydraulic cylinder can no longer directly be connected to the pick-up and tilting device, a transmission linkage must be provided here, which is an implementation of the linear piston movement allowed in a swivel movement of over 100 degrees.

The use of hydraulic drive means has opposite mechanical drive means the advantage that one of the geometric shape of the swivel device or Swivel arm pairs is independent because the energy supply to the Drive means take place via pipes and / or hoses can easily the contour of the swivel device can be laid in the following. When using a Swivel arm pairs are conveniently on each swivel arm an oil motor or a hydraulic cylinder arranged. At the use of hydraulic cylinders are expedient designed as a double-acting cylinder, so that through appropriate control of the inflow and outflow the hydraulic fluid the required synchronization, d. H. Movement of swivel device and pick-up and tilting device with the same swivel speed but opposite Direction of rotation can be achieved.

In an embodiment of the invention it is provided that the drive means to synchronize with the pivoting movement the swivel device with a swivel movement connected to the swivel device driven pump unit is. This pump unit is only used for the drive of the hydraulic drive means of the receiving and Tilting device and the swivel drive itself Swivel device driven. The desired control the pick-up and tilting device depending on the swivel angle the swivel device is thereby easier Way to accomplish. When using an oil engine is a corresponding unit working as a pump intended. When using hydraulic cylinders in this case one or more actuable for the swivel device to arrange hydraulic piston-cylinder units on the vehicle.

In a further advantageous embodiment of the invention provided that the drive means at the same time the tilt drive forms, wherein reversing means are provided by the Reaching the emptying position for the waste container from the pump unit for synchronization control to one Pressure oil supply switched and the pick-up and tilting device pivoted in the tilt position and back into the vertical position is pivoted back, and then back up Synchronous control is reset. This reduces the construction effort considerably, with advantage - for example when using hydraulic cylinders - exploited can be that due to the opposite pivoting movement with appropriate dimensioning of the hydraulic cylinders, these are in an end position when the tilt position is reached, so that practically the full for the tilting movement for emptying Cylinder stroke is available again.

In a further embodiment of the invention it is provided that the pair of swivel arms is connected to means that one Shortening of that by the pair of swivel arms and the one taken up Waste bins given overall radius at least in the area effect above the cab. The funds can in an embodiment according to the invention in telescopic the swivel arm pairs are made with extensions which the receiving and tilting device is connected. The In another advantageous embodiment, means can be obtained by one connected to the free ends of the swivel arm pair Guide arm pair are formed.

In a particularly advantageous embodiment of the invention it is provided that the pair of guide arms between the free Ends of the pair of swivel arms are pivotally arranged is and during the entire swivel path through the guide means essentially against the vehicle and under one constant angle aligned with the horizontal is held. With such an arrangement, it can especially on vehicles with a lowered cab achieve that the swiveling process into the emptying position, but in particular also the tilting of the recorded Waste bin for emptying, a space that needs by the approved height of the collecting container on the Vehicle does not exceed or only slightly exceeds. Another The advantage of this arrangement is that the guide means is much easier to design by which vertical alignment of the receiving and tilting device during of the swivel path extending over the cab is effected. The arrangement of the between the free ends of the pair of swivel arms which can be swiveled through allows this guide means between the articulation area the free ends of the swivel arm pair and the guide arm pair assign while the tilt drive in turn is mounted on the pair of guide arms. This results in a Decoupling, which leads to a considerable constructive simplification leads.

In a particularly advantageous embodiment of the invention provided that the drive means for vertical guidance of the Waste container by at least one on the receiving and Tilting device or on the swivel bearing of the swivel arm pair fixed first gear and by a Pivotal point of the receiving and tilting device or the pair of guide arms formed with this fixed second gear with a form-fitting, endless traction device, in particular a chain connected to the first gear is. The chain rolls when the pair of swivel arms is pivoted on the fixed gearwheel and thereby swivels the receiving and tilting device or the pair of guide arms relative to the pair of swivel arms. By choosing the gear ratio between the first gear and the second Gear can now "lead" depending on the dimensioning or "lagging" the relative movement of the guide arm pair can be effected relative to the pair of swivel arms, wherein however, the alignment of the pair of guide arms in space in the essential should be preserved. For gear wheels of the same size Accordingly, there is a constant alignment the pair of guide arms in the room during the entire swiveling process, so that also a picked up waste container remains vertically aligned at the end of the swiveling process, so that the tilting process is only initiated via the tilt drive when the waste container is over the filler opening located. Expediently are on each Corresponding gear wheels and endless chains arranged, for maximum utilization of the system with regard to to achieve the weights to be mastered.

In a further advantageous embodiment of the invention provided that the pair of swivel arms with its swivel bearing can be pivoted about a vertical axis with a rotary bearing is connected to the carrier. This arrangement has the advantage that the waste container to be picked up not only from one Position in front of the cab but also from one position can be recorded next to the lane of the vehicle. This offers the possibility of collecting the waste containers to be placed in a row next to each other and with to drive the vehicle along the row and one after the other to take up and empty the individual waste containers and drop it off next to the vehicle. Another advantage this arrangement is that such a vehicle is also able to get a second, on a trailer to carry carried container, which in particular is advantageous if larger amounts of waste in rural areas Areas or special waste in addition to normal waste must be collected. For this purpose the Trailer with its special waste container next to it set up the vehicle so that the normal Waste in the collection container on the vehicle and the Waste containers containing special waste in the adjacent one Trailer or a second container Be emptied.

In a further embodiment of the invention it is provided that the pivot bearing with the carrier in the longitudinal direction and / or in Transversely to the vehicle is slidably connected. The in addition to the possibility of pivoting the pair of swivel arms Slidability given about a vertical axis offers the advantage that changes in distance in horizontal Direction can be done with the entire system can without having to move the vehicle itself. This is both for holding the waste bin in the front area and beneficial in the side area of the vehicle as well for the use case when a waste container in a next to the Vehicle emptied on a trailer container shall be. It is useful here if the pivot bearing with the carrier in the longitudinal direction to the vehicle is connected and the pivot bearing transverse to its axis is slidably connected to the pivot bearing. Here too results a decoupling that simplifies the construction of the individual movement elements, so that here too the associated ones Drives for movement, for example hydraulic Actuable piston-cylinder units in a simple way can be arranged.

In a further advantageous embodiment of the invention provided that in the area of the rear end of the vehicle chassis a crossbar for support, guidance and locking of the collecting container which is arranged around a in Swivel axis extending in the longitudinal direction of the vehicle is mounted, preferably the pivot axis with the Joint axis of the third attachment point of the carrier flees. This configuration has the advantage that despite the practically rigid coupling of the rigid container to the likewise rigid support, the Vehicle chassis itself while driving in the intended manner can twist around the longitudinal axis without this Squeezes between the collection container and the vehicle chassis is coming. The collection container is also in one Three-point support connected to the vehicle chassis, the two front support points through the fixed Support points of the carrier formed on the vehicle chassis during the third point of support through the Swivel bearing of the crossbar is formed. That is the crossbar supporting joint can also be done by a Ball joint are formed.

In an advantageous embodiment of the invention is also provided that at least one between crossbar and Effective positioning spring element provided in the vehicle chassis is. This ensures that in the unloaded state the crossbar with guide rollers and / or locking elements is provided for the collection container in relation is aligned horizontally on the vehicle chassis, so that when picking up or driving under the collecting container Bottom rails can engage precisely in the guide rollers.

a connection between press and collecting container in detail.

The vehicle shown in Fig. 1 for picking up and transporting of waste is with a lowered Cab 1 provided so that above the cab greater free space is available. Is on the vehicle furthermore, a collecting container 2 is arranged releasably, via Pin or fasteners 3 is attached. The collection container 2 can here after loosening the closures 3 in different Be removed from the vehicle. This can either in that the collection container 2 down has extendable supports shown in more detail in FIG. 12, so that the vehicle comes with a lowering device is equipped after lowering from the elevated Can drive away the container. The recording then takes place in reverse order, as is shown in FIGS. 12 to 15 will be explained.

But it is also possible to use an additional vehicle to provide so-called hook lift, through which a recorded Collect the container a short distance to the rear is moved horizontally and then by pivoting the Lift hook is pushed further back, so that Vehicle as soon as the collecting container with its rear edge touches the ground, with further pivoting of the lift hook can drive forward and the collection container can settle on the floor. Picking up an empty one Collecting container is done in the same way. Such hook lift constructions are known and need here in their Structure not to be explained in more detail. The one carrying the hook Arm must, however, be designed in a bow shape, so that he Grips the discharge opening of the hopper.

Another option is to use the vehicle to provide a so-called tipping bridge, which with a Cable winch is equipped so that after releasing the lock and again moving the collection container in a horizontal direction backwards, the tipping bridge swung up and the collecting container with the help of the winch the inclined tipping bridge can be lowered, until again the rear edge of the collecting container the bottom touched and drive the vehicle forward while lowering further can until the collection container is finally on the floor lies on. The recording is done in reverse.

The arrangement of a tipper bridge allows it if instead a hydraulic lifting device is provided for a cable winch is, the collecting container instead of being placed on its bottom surface this on its rear face perpendicular to set up. It is only necessary to do this at Swing up and lower the collection container at the same time to pivot the tipping bridge to the 90 ° position as soon as the Collecting container with its lower rear edge on the floor gets up. The vehicle then reverses accordingly. The recording takes place in reverse order.

The rear end wall 4 of the collecting container 2 is more common Formed as a lockable flap, so that after Open the lock of the contents of the collection container by Tipping can be emptied. The collection container can also be designed so that the front end wall 5 as an emptying flap is trained and completely for emptying can be folded up.

On the front end wall 5 there is a filling opening in the lower area 6 provided over one on its outside attached door 7, for example a vertically displaceable and lockable sliding door is lockable.

On the vehicle itself is in the space between the cab 1 and the end wall 5 of the collecting container 2 a press arranged, the hydraulic press cylinder 8 and one Press ram 9, dashed here in the press position is shown. The press also has a hopper 10 on, the discharge opening through a tubular Extension 11 is formed, which is dimensioned so that it through the filling opening 6 of the collecting container 2 into this protrudes. Now 9 waste with retracted ram thrown into the hopper 10, this can over the press ram 9 through the tubular extension 11 of the discharge opening of the hopper 10 in the Collection container 2 are inserted. The tubular extension is, as will be explained below, in Collection container encompassing the edge of the filling opening assigned channel-like protective cover 66 into which the extension 11 is introduced. Not only does this allow Arrangement of seals covering the gap between extension 11 and protective cover 66 over at least part of the Seal circumference, but also the arrangement of an additional Locking flap inside the collecting container, to the Loosen the collecting container 2, the leakage of partial quantities of the Prevent container contents.

On the inside of the end wall 5 of the collecting container 2 can also above the filler opening 6 over the Width - hinged flap extending the filling opening 12 may be arranged, which is dimensioned so that when inserted Extension 11 rests on this. Now the container 2 is withdrawn, then the flap pivots 12 down and covers the upper area of the filler opening 6 and secures them against falling out of the container contents, until the door 7 is closed.

The hopper 10 runs upwards in side walls 13, which are essentially beyond the driver's cab 1 extend into the front area. In Fig. 1 is for Not simplifying the illustration of the front side wall shown. The upper edges 14 of both side walls are with a guide for a displaceable and preferably windable Cover 15 provided so that the space above the Driver's cab and the press are completely closed while driving can be. Via a displacement drive 16, for example a winding device, then this space can be opened by pulling back the cover 15. The end 17 of guides 14 adjacent winding device 16 is expediently designed so that it at withdrawn cover as shown in dashed lines, can be swung up. On the one hand, this becomes the for the pivoting and pouring process, as described in more detail below described, required free space increased and others, however, the opening of the hopper 10 up to covered to a certain degree, so that, for example, at Rainy weather the entry of rain into the hopper is largely prevented. If the cover 15 is pulled back completely, must have an additional cover plate for shielding be provided.

The vehicle described with reference to FIG. 1 is now for the Changing the collecting container 2 so designed that the collecting container 2 with extendable downwards, not closer here shown supports is provided, the vehicle itself to release the container after opening the closures 3 can be lowered by a small amount and therefore under the container can drive out. To at such a trained Vehicle inserting the tubular extension 11 in to facilitate the filling opening 7 of the collecting container, the vehicle has one with a hydraulic cylinder as Drive provided carriage 18 on the vehicle can be moved with a displacement of about 50 to 100 cm is stored, as Fig. 2 shows. The carriage 18 carries the front closure designed as a driver 3. Located the carriage 18 is now in its rearward position, then the vehicle can be used to pick up an elevated Collecting container 2 in the lowered state under this drive until the front closure element on the collection container 2 is approximately over the closure 3 of the carriage 18. Then the vehicle is raised so that the shutter 3 in the Closing element engages the container 2 and the closure 3 closed. Now the carriage 18 is after moved at the front so that when the door 7 is open, the tubular Extension 11 can enter the fill opening 6. This process is in its sequence in FIGS. 12 to 15 shown.

To automate the opening of door 7 here is now on A functional device 19 is provided in the vehicle, for example in the form of an endless chain or a toothed belt 20, which is provided with a driver 21. The chain 20 is via a drive 22, for example a hydraulic motor, drivable. The door 7 designed as a sliding door the filling opening 6 now has a corresponding catch, in which the driver 21 can engage, so that when advancing over the carriage 18 of the driver 21 initially engages in the catch of door 7 and via the functional device 19 opened the door by moving it upwards can be. The carriage 18 then moves on forward until the extension 11 through the filler opening 6 is inserted and the rear container end with the associated Closure 3 can also be locked.

With this system it can also be useful if the Functional device 19 with the carriage 18 a structural unit represents so that when picking up a collection container in the manner described above, the latching of the door 7 in the driver 21 already intervenes, even if the one with the sled 18 connected closure 3 is locked. The door 7 can then be opened before the collection container 2 through the sled towards the tubular extension 11 the press is moved. Can on the functional device also correspondingly controllable and drivable actuators for the actuating and locking means one in Collection container arranged locking plate may be arranged.

In the case of a version with a hook lift, this replaces this System usual building component for the horizontal displacement until finally locked, as described above Slide 18. The lift hook is corresponding frame-shaped, so that in the operating state tubular extension 11 of the press 7 on its outside is included. With this system, the functional device in the angled, i.e. in the operating state upwards pointing part of the lift hook can be integrated.

In Fig. 3 is now in connection with the above Vehicle a device 23 for picking up and emptying a waste container 24 shown and described. All explained in detail above and for explanation the function of the device 23 unnecessary elements are omitted in Fig. 3 for simplicity of illustration. The device 23 is supported by a pair of swivel arms 25 formed, the swivel arms parallel to each other and in one The distance from each other is approximately the width of the cab 1 corresponds. The pair of swivel arms 25 is with a swivel bearing 26 in the front area above the cab 1 arranged on a carrier 27. The pair of swivel arms 25 is provided with a swivel drive which is designed in this way is that the swivel arm over an angle of about 180 ° from the lower recording position shown in the Upper rest position 25 'shown in dashed lines pivoted can be. The swivel drive can, for example, by one or more hydraulic piston-cylinder units are formed, with corresponding lever arrangements the required swivel angle can be achieved. this will 4 to 6 are shown in more detail. Appropriately is also the design of the swivel drive in the form of a so-called hydraulic swivel motor. Here two telescopically nested, with wide helical teeth Provided shaft-piston elements hydraulically axially postponed. The axial movement is determined by a corresponding internal toothing fixed to the housing, which with the toothing of the Shaft interacts, converted into a rotary motion.

In the embodiment according to Fig. 3 is the pair of swivel arms 25 is now connected to a guide means 28, the one Pick-up and tilting device 29 for the waste container 24 wearing. The guide means 28 is designed here that while extending over the cab 1 Swivel path of the waste containers 24 aligned approximately vertically remains and until the pair of swivel arms in the fully extended emptying position swiveled 25 '' has been. In this position, the waste container 24 load-bearing pick-up and tilting device via its own Tilt drive, not shown here, for example a hydraulic piston-cylinder arrangement mounted on the guide means, pivoted into the emptying position shown, so that the container contents into the hopper 10 the press 7 can occur.

The representation of the device 23 in three different Positions of their swivel path indicate that already when shooting and over the entire swivel path Waste container 24 with its guide means between the Swivel arm pair is pivoted through, so that the necessary Free space practically over the free end 30 of the two swivel arms is limited, i.e. at no time neither by the pair of swivel arms still through the container this area is significantly exceeded. The representation in FIG. 3 also shows that that required by the device 23 in operation Free space through the upper edge of the collecting container 2 exceeds the specified height only slightly, so that a Clearance profile of less than 4.3 m can be maintained can.

The guide means 28 is in the illustrated embodiment formed by a pair of guide arms 31, each Guide arm each at the free end 30 of a swivel arm 25 is articulated. The receiving and tilting device 29 is then with its tilt drive on the free ends of the pair of guide arms 31 mounted. The pair of guide arms 31 is connected to the pair of swivel arms 25 so that it during the entire swivel path essentially against that Vehicle and at a substantially constant angle remains aligned with the horizontal like this can be seen from the drawing. There is a drive for this provided, which essentially consists of one in each Swivel plane of the pair of swivel arms 25 fixed on the swivel bearing 26 Gear 32 and each one with one Guide arm firmly connected gear 33 is formed. Both Gears are connected to each other via an endless chain 34 connected so that when pivoting the pair of swivel arms 25th the chain 34 "rolls" on the fixed gear 32. Since both gears have the same diameter, hereby the gear 33 and thus the associated guide arm kept in the same orientation with respect to the vehicle like the fixed gear 32. By different Gear diameter can now provide a "translation" be the more or less strong change of the Alignment of the pair of guide arms with respect to the vehicle causes so also to the "geometry" especially for to be able to carry out the area of the emptying position 25 '.

Fig. 3 also reveals that shown in dashed lines Rest position 25 'the device 23 overall within of the space predetermined by the side walls 13 above the cab 1 can be pivoted. So that is it is possible, as already described above with reference to FIG. 1, the device 23 for pure driving operation completely covered after closing the cover 15 is.

In Fig. 4 is the embodiment explained in Fig. 3 in the basic structure shown on a larger scale and in more detail.
