A return spring 17 'pulls the lever 32 against a stop 34 in the Starting position.

5 and 6 is a further embodiment of a tableware 20 shown. This tableware 20 is rectangular by two by an adapter 48 axles swinging to each other on the jib of a mobile crane attached. The receiving tableware 20 has a lower pressure bar 23 ' is attached to the adapter 48 via a support plate 50, swinging about the axis 49. On A hydraulic cylinder 24 is supported on the pressure beam 23 ′ and has a slide 41 can lift relative to the pressure beam 23 '. The carriage 41 consists of a Support hook 42, at the ends of guide sleeves 43 and gripping hooks 22 are fastened. The guide sleeves 43 are guided on guide columns 44 which are rigid on the pressure beam 23 'are attached. On the sides of the slide 41 are the tabs 45 Gripping hook 22 attached, which - as Fig. 7 shows - above the top of the Reach under the container 1 attached to the container 1 support profile 19. The hydraulic cylinder 24 forms, together with the slide 41, the gripping hook 22 and the pressure beam 23 'the emptying device. To empty it on the control block of the Vehicle actuates a valve that the hydraulic cylinder 24 via hydraulic hoses 51 supplies hydraulic oil so that the carriage 41 together with the gripping hook 22 starts up until the upper ends 39 of the locking devices leading push rods 14 against the pressure beam 23 '. By pushing down of the push rods 14, the hooks 8 and 9 of the locking device get into the Unlocking position so that the bottom flaps 4 and 5 open and the container contents can slip out.

The hooks 22 are connected to the slide 41 via tabs 45. In one Small distance above the gripping and carrying hooks 22 is about the axis 47 a securing part 46 is pivotably mounted, which is supported by a return spring in the Fig. 6 apparent blocking position is held, the unwanted lifting of Container 1 prevented because the carrier profile 19 located in the hook 22 at the Fig. 6 apparent position of the securing part 46 is not lifted out of the hook 22 can be.

In this position of the tableware 20 and container 1 the container is emptied. As can be seen in particular in FIG. 11 also in this position, in which the securing parts 46 have already been swung out, the container 1 cannot be lifted out of the hook 22 because of the pressure beam 23 'prevents this.

After the container 1 has been emptied, it can be moved from the vehicle to one location transported in which it can be placed.

The container 1 is deposited in that the mobile crane carries the tableware 20 with the container 1 held therein but still open settles. The bottom flaps 4,5 close. Now the carriage 41 can the gripping hook 22 can be moved down. The fuse parts remain 46 in the open position because this slides down when the slide 41 are held in the open position by the carrier profile 19 of the container 1.

As FIG. 12 shows, the receiving tableware 20 can then be used with the gripping hooks lowered 22 are moved laterally away from the carrier profile 19, so that the mobile crane the tableware 20 with the still below the upper edge 37 of the container 1 located gripping hook 22 can pull up.

Fig. 7 shows the situation before receiving a container 1 in the dishes 20 of the vehicle. With the help of the mobile crane, the receiving dishes 20 with the pressure bar 23 'on the upper edge 37 of the collecting container 1 discontinued. The gripping hooks 22 are already below the carrier profile 19. By pulling up the tableware 20 and at the same time laterally Movement to the support profile 19 under the gripping hooks 22 under the support profile 19 of the container 1. The safety parts 46 open automatically against the Effect of the return springs. The container 1 can now be completely secured by the mobile crane be lifted and transported. Is the discharge point for the Container 1 reached, the hydraulic cylinder 24 presses the carriage 41 and thus the upper bar 42, the gripping hooks 22 and the carrier profile 19 with the container 1 up. The upper ends 39 of the push rods 14 abut against the lower pressure beam 23 ', so that the hooks 8 and 9 of the lock in the unlocked position be pivoted and open the bottom flaps 4,5 and the Container contents slip out. The container 1 can now be seen in FIG. 11 secured position to be transported back and parked on the floor become. Only then - as shown in FIG. 12 - are the slides 41 with the gripping hooks 22 lowered so that the tableware 20 is free to accommodate another Container 1.

Instead of a continuous support profile 19 can also depending on the side of the container two cantilever arms are arranged by the gripping hooks 22 of the receiving harness 20 can be undertaken.

The waste collection container according to the invention and the vehicle with the receiving dishes for this collection container have the advantage that the Transporting, emptying and depositing the container 1 from the control block of the Vehicle can be accomplished and that an unwanted lifting of the Container from the tableware 20 of the vehicle is not possible.

Instead of the automatically pivoting securing part 46, it is also possible to Attachment harness 20 to attach a securing part, which is also from the control block is controlled from the vehicle. However, such a backup is clear more expensive than the fuse according to FIGS. 5 to 12.
