Lifting and tipping device for recyclable waste collection containers or similar.

The invention relates to a lifting and tilting device for recyclable waste collection containers or the like, with a lifting device for lifting and lowering a container and a tilting device for tilting the container for emptying purposes, each of which has a load-carrying device to be brought into engagement with the container in the form of at least one drivable rope or the like.

Growing environmental awareness has for some time now led to waste being collected separately and recycled in order to conserve resources. For this reason, so-called recycling bins are set up in many places in municipalities, into which waste such as glass, cans, plastics, paper, clothing, etc. can be thrown separately. These bins must be emptied regularly so that they can be recycled by

BOEHMERT & BOEHMERT,

They must be lifted from their storage location, loaded onto a truck and emptied by tipping at a collection point. Since recyclable waste collection containers come in a variety of different sizes and shapes, and their weights sometimes vary greatly due to the different contents, there are special requirements for the corresponding lifting and tipping devices.

To date, special devices have been used for this work, which have two arms extending in the longitudinal direction of the vehicle in question, arranged on the two side edges of the loading area, which are connected to one another via cross braces. Such known lifting and tipping devices cannot be pivoted about a vertical axis, so that the major disadvantage is that the truck in question has to drive in a certain direction towards a container to be loaded in order to be able to pick it up. The same applies to emptying a container by tipping, since this can only be done in a special position, e.g. over the rear.

Another significant disadvantage is that such devices are only suitable for specific container sizes and shapes, since the support points on the containers and on the lifting and tilting devices must be coordinated with one another.

The present invention is based on the object of creating a lifting and tilting device of the type described above, with which such containers can be lifted, loaded and tilted (and thus emptied), whereby the

BOEHMERT & BOEHMERT, H©RDSMAN.I» and

The device should be able to pick up and empty the load from different positions, for example, even over common obstacles such as fences, cars, etc. The device should be designed so that it can be used for different container sizes/types and should preferably be collapsible so as not to restrict the size of the containers to be handled.

The solution to this problem is characterized according to the invention by a design as a hydraulic loading crane, the boom of which has at least two extensions in a manner known per se, the tipping device being arranged on the outer end section of the outermost extension and the lifting device being arranged on the one extension of the boom that is further inward.

According to a preferred embodiment, the lifting device is arranged at the end section of the extension adjacent to the outermost extension.

Preferably, the boom can have more than two extensions.

Furthermore, it is preferred that the extensions - with the exception of the outermost extension - are controlled in a manner known per se with a hydraulic sequential control, and that the outermost extension is to be controlled separately.

Preferably, the outermost extension can be mechanically detachable.

BOEHMERT & BOEHMERT, NORDIMANN BNDsPAjCff

Most preferably, the drive for the load-carrying device of the tipping device is a cylinder winch.

Furthermore, the cylinder winch is preferably arranged at the outermost extension of the boom and essentially parallel to it.

In the following, the invention is explained in more detail using exemplary embodiments with reference to a drawing. It shows:

Fig. 1 is a side view of a first embodiment of a lifting and tilting device according to the invention, which is mounted on a vehicle, the lifting and tilting device being shown folded up in the lower part of Fig. 1 and in the upper part with a suspended container in the retracted state ;

Tilting device of another exemplary embodiment.

Fig. 1 shows a side view of a lifting-tilting device 1 mounted on the loading area 4 of a vehicle 6, which has a tilting device designated as a whole by 2. In the present case, the lifting-tilting device 1 (referred to above and below as "device") is behind the driver's cab 3 on the loading area 4 of the chassis 5

mounted so that it can load and unload the loading area 4, but itself requires very little space. The device 1 can be rotated up to 410° or unlimitedly around a vertical axis 7, depending on the type, and can also be folded up, as can be seen in Fig. 1. The latter is important, among other things, so that the height of the container 8 is not restricted by the device 1 because the total height of the vehicle 6 (including the load) must not exceed 4 m.

The boom of the loading crane 1 is made up of several parts and consists of a column 9 and first and second boom parts 10, 11, which are connected to one another in a manner known per se via joints and hydraulic cylinders (not shown). With such a lifting and tilting device 1 designed as a loading crane, it is also possible to reach loads 8 that are in the immediate vicinity - regardless of the current position of the vehicle 6.

The outer boom part 11 has three telescopically movable extensions 12, 13 and 14, whereby extension 13 is referred to below as the penultimate extension and extension 14 as the last extension. The first two extensions 12, 13 are hydraulically controlled in a sequential control, whereas the last extension 14 is not included in this sequential control, but is separately hydraulically operated via a separate valve. In this way, the last extension 14 can be extended to a certain length independently of the other extensions 12, 13.

As can be seen in Fig. 1 and 2, a lifting device is provided at the outer end section 15 of the penultimate extension 13.

BOEHMERT & BOEHMERT ₁

16 is arranged to receive a container 8. The lifting device 16 has a hook 17 into which a chain or a crossbar 18 with a handle is hooked, whereby the crossbar 18 is connected to the container 8 via a chain 19.

The outermost extension 14 has a deflection device 21 in the form of a deflection pulley or a roller head on its outer end section 20. This deflection device 21 serves to tilt a container 8, which has been lifted by means of the lifting device 16, for emptying via an adjustable pulling element 22, such as a cable. The cable 22 is taken up by a hydraulically operated cable winch 23. In order to exert a tilting moment on the container 8, the cable 22 is attached to a support 24, which is arranged in the lower side or edge area of the container 8, and is hooked in with a hook 25.

Fig. 3 shows a further embodiment of the lifting and tilting device 1 according to the invention, in which the tilting device 2 has a cylinder winch 25 arranged in the outermost extension 14 for adjusting the pulling element 22. Here, too, a deflection device 21 designed as a double roller is arranged on the outer end section 20 of the outermost extension 14. The cylinder winch 26 includes, among other things, a hydraulic cylinder 27, which runs essentially parallel to the outermost extension 14, and a deflection element 28 designed as a roller head. By operating the hydraulic cylinder 27, the deflection element 28 moves away from or closer to the deflection device 21 arranged on the end section 20 of the outermost extension 14, so that the

formed pulling element 22 is adjusted in a pulley-like manner, wherein the end of the rope 22 is in turn attached to a support 24 arranged in the lower edge region of the container 8, so that the container 8 can be tilted with the rope 22 for emptying.

In the following, the lifting and tilting process of the lifting-tilting device 1 according to the invention is briefly explained again:

Depending on the size, shape and weight of the container 8, it is attached to the lifting device 16 arranged on the penultimate extension 13 using suitable load-bearing means (e.g. chains 19 and a crossbeam 18). The attachment points 29 on the container 8 are arranged in its edge area and symmetrically to its center of gravity, so that uncontrolled slipping or tipping of the container 8 is avoided when it is lifted by the device 1. In this way, the container 8 is lifted at a storage location for recyclable waste collection containers and loaded onto the loading area 4 of a vehicle 6 for transport.

If the container 8 is to be emptied at a collection point, the hook 25 of the load-carrying device 22 of the tipping device is hooked into a support arranged in the lower edge area of the container 8 - just as the hook 17 has been hooked over the support beam 18 and the chains 19 at the symmetrically arranged fastening points 29 of the container 8 - whereby the corresponding cable length is released by the cable winch 23, for example the cylinder winch 26, and the outermost extension 14 is extended to a length adapted to the size of the container 8. After the device

-δ&igr; has been extended into the position in which the container 8 is to be emptied, the load-carrying means 22 running through the deflection device 21 is pulled upwards by the cable winch 23, for example the cylinder winch 26, so that the container 8 is tilted for emptying (as can be seen in Fig. 2). The load-carrying means 22 is then extended again, whereby the previously raised part of the container 8 is lowered again until it is essentially horizontal and can be unloaded onto the loading area 4 of the vehicle 6 for return transport.
