Description

The invention relates to a vehicle crane. In particular, the invention relates to a vehicle crane having a housing enclosing a vehicle interior and a crane rotatably arranged on the vehicle crane by means of a pivot drive, wherein the pivot drive has a first raceway connected to the vehicle and a second raceway rotatably mounted with respect to the first raceway and connected to the crane.Crane vehicles are generally known and are of very different embodiments, for example from DE 10 2008 047 737 A1 and EP 1 342 615 B1. In the military sector, these are frequently used as mining vehicles.If the crane vehicle has a crane which is rotatably arranged on the vehicle by means of a pivot drive, the slewing gear is connected to a supporting frame which is configured to pick up and transmit the loads arising on the crane into the chassis or in supports connected thereto. In this case, the slewing gear and the supporting frame carrying the slewing gear can be housed for protection against environmental influences.A disadvantage of this construction is that the construction of a supporting frame is labor-intensive, wherein the supporting frame itself can have a high own weight which additionally loads the weight of the crane vehicle and additionally takes up a large amount of space on the vehicle. Especially in the design of military crane vehicles, the additional weight and the additional space requirement are contrary to the design of modular mission modules.It is therefore the object of the invention to provide a crane vehicle with a crane, the connection of which to the vehicle as a whole is space-saving and weight-saving.This object is achieved according to the invention by the vehicle crane having the features of claim 1. The dependent claims represent advantageous embodiments of the invention.The basic idea of the invention is to incorporate the slewing gear of the crane of a crane vehicle directly and without carrying frames into a load-bearing housing of the crane vehicle which accommodates and transmits the loads of the crane. By eliminating an additional heavy and space-consuming supporting frame, the weight of the vehicle crane can be reduced overall, wherein additional functions can be realized by saving the otherwise necessary space. This advantage is obtained in particular in military vehicles, in which a housing designed to transmit load simultaneously offers ballistic protection because of its required strength.According to the invention, a vehicle crane is therefore provided having a housing enclosing a vehicle interior and a crane arranged rotatably on the vehicle crane by means of a pivot drive, wherein the pivot drive has a first raceway connected to the vehicle and a second raceway rotatably mounted with respect to the first raceway and connected to the crane, wherein the first raceway of the pivot drive is connected to the housing designed to transmit the loads of the crane directly into the housing.According to a preferred embodiment, the pivot drive is embedded in the housing on the upper side of the housing.The housing is preferably designed closed, but can be equipped with a door or a hatch for access to the interior enclosed by the housing. Particularly preferably, the housing has a cabin having a door or a hatch, which cabin is accessible to operating personnel operating the crane vehicle. In particular, the cabin can be designed as a passenger compartment and can completely accommodate the operating personnel. For this purpose, the cabin has, in particular, means for actuating the crane and / or for moving the crane vehicle as a whole.Furthermore, it is preferably provided that the housing is designed as a vehicle module detachably connected to a travel module of the vehicle crane. The modular character makes it possible to equip travel modules with different vehicle modules, so that the crane vehicle, for example, with cranes of different design, but also with other (mission or mission) The vehicle modules may be operated.For safe operation of the vehicle crane, the vehicle crane according to a further preferred embodiment has supports for stabilizing the vehicle crane or the vehicle module. If the supports are connected directly to the load-transmitting housing, it is possible, in particular if the supports are configured in addition to lifting the vehicle module from the travel module of the vehicle crane, to replace the vehicle module without any tools or other tools. For this purpose, the vehicle module is lifted from the driving module by extending the supports, so that the driving module can move away under the lifted vehicle module, at least when a driver's own cab is provided. If appropriate, the supports must additionally be underfed for this purpose. If necessary, the vehicle module must be decoupled from the driving module beforehand or corresponding fuses holding the modules together must be released.The supports are preferably arranged laterally and on the end side of the vehicle module forming the rear of the crane vehicle, wherein preferably three supports are provided.The vehicle module is further preferably configured for autonomous operation of the vehicle module and has its own energy supply for this purpose. This embodiment not only enables autonomous operation of the vehicle module on the driving module, but also enables autonomous operation of the vehicle module if the latter is decoupled from the driving module and is set on its own supports, as described above.Finally, it is preferably provided that the vehicle crane is a military vehicle crane, especially a mining vehicle. The military vehicle is in particular armoured and designed as a mountain armour. The suitability of the crane vehicle as an armoured military vehicle arises in particular for the case where the load-transmitting housing of the crane is made of steel, in particular armour steel, and thus per se offers good ballistic protection.The invention is explained in more detail below with reference to an exemplary embodiment which is illustrated in the appended drawings and is particularly preferably designed. The following are shown: FIG. 1 shows a side view of a particularly preferably configured crane vehicle according to the invention; and FIG. 2 shows a side view of a particularly preferably configured vehicle module.FIG. 1 shows a side view of a particularly preferably configured crane vehicle according to the invention. In particular, FIG. 1 shows a vehicle crane 100 designed as a military mining armour in its working position. The vehicle crane 100 is of modular design and comprises a travel module 10 which has the chassis and the chassis and a driver's cab for moving the vehicle crane 100, and a vehicle module 20 which is detachably connected to the travel module 10.The vehicle module 20 is a mining module equipped for mining purposes and has a housing 30 enclosing a vehicle or module interior and a crane 30 rotatably arranged on the housing 30 by means of a pivot drive 40. The swivel drive 40 is let into the housing 30 at the top of the housing 30 and has a first raceway connected to the housing 30 and a second raceway rotatably mounted with respect to the first raceway and connected to the crane 50, wherein the first raceway of the swivel drive 40 is connected to the housing 30 so as to directly introduce the loads of the crane 50 into the housing 30, and is connected to the housing 30 so as to transmit the loads of the crane 50. The housing 30 of the crane vehicle 100 or of the vehicle module 20 is manufactured in particular from armour steel.The housing 30 is basically designed closed, but can have ventilation slits or a door or a hatch for access to the vehicle interior, which is designed in particular as a cabin and is set up for receiving operating personnel operating the vehicle module.In order to stabilize the vehicle crane 100 or the vehicle module 20 in the working position, the vehicle module 20 has supports 60 connected to the load-transmitting housing 30, which supports are arranged in particular laterally on the vehicle module 20 and at the rear thereof.As FIG. 2 shows in a side view of a particularly preferably configured vehicle module 20, the housing 30 is designed as a vehicle module 20 detachably connected to the travel module 10 of the vehicle crane 100. In particular, it is provided that the supports 60 are configured to lift the vehicle module 20 from the travel module 10 of the vehicle crane 100. The driving module 10 can therefore place the vehicle module 20 at a suitable location in that the vehicle module 20 itself lifts from the driving module 10 and releases the driving module 10 which can move out under the lifted vehicle module 20. The vehicle module 20 itself remains placed on the supports 60 in situ, optionally resting on a underlay.This configuration is particularly useful when using a crane required both in a mobile and stationary manner, without the travel module itself having to remain on site when a crane is stationary. Rather, the vehicle module is configured for autonomous operation with its own energy supply, so that lifting tasks can be carried out stationary not only mobile on the driving module, but also decoupled therefrom.In particular, the invention provides a mobile crane within the scope of a vehicle crane which, in the case of a modular configuration of the vehicle crane having a travel module and a vehicle module carrying the crane, is to be used both in a mobile and stationary manner and without a travel module.
