Definitions
- the invention relates to a vehicle crane consisting of a vehicle with Chassis and attached supports, which are from a folded transport position be moved into a deployed working position, a revolving stage and a Crane construction on the revolving stage.
- the object of the invention is the crane size, taking into account the maximum axle load 12 t and the legally permissible overall height.
- a vehicle crane with the combination of features of claim 1.
- the from a vehicle with chassis and attached supports, from a folded Transport position can be moved in a deployed working position, a revolving stage and a crane superstructure which can be built on the revolving platform, the chassis designed with supports such that they have the maximum height allowed Transport state, for example, the allowable height of 4m exploit.
- Very high heights result for the support.
- This can be a larger Support base can be selected, which makes the crane very high loads with comparatively low ballast can lift.
- This reduction of the necessary ballast leads to great advantages especially in rapidly changing places of use.
- the weight of the ballast to be transported can be reduced, so that also here the transport costs can be reduced.
- the object initially posed is further by a vehicle crane with the Combination of the features of claim 2 solved.
- Revolving stage coupled with the vehicle such detachable, that they are used for road transport is separable from the vehicle. This will ensure that the height the turntable does not also take up part of the vehicle height, so that the attached supports, which from a folded transport position in a deployed working position are movable, the maximum permissible height in the Be able to take advantage of transport condition.
- the vehicle has four swivel mounted on its chassis Props up.
- These four supports can have piston-cylinder arrangements be swiveling.
- the four supports are telescopic in length, so that the Support base can be further increased.
- the articulation points of Supports arranged in the middle area of the chassis, with the free ends of the Support in transport position respectively in the direction of the driver's cab or the vehicle's rear are aligned.
- the rear supports not only in one Transport and working position are pivotable, but also in a position between these two end positions, in which the support base of the crane to the rear - Especially when erecting the boom - can be improved.
- After complete Erecting the boom can then move the props further into a working position be pivoted so that here a uniform support in a 360 ° Pivoting range is ensured.
- the supports can in transport position essentially the space between Take the chassis and the overall height of the vehicle.
- the revolving stage connectable with the vehicle with a quick connection. This is a quick one Building and removing the revolving stages allows.
- FIG. 1 10 is a vehicle crane according to an embodiment of the present invention Invention referred to.
- the vehicle crane consists of a vehicle 12 with in The representation of Figure 1 in the working position unfolded supports 14, 16, 18th and 20.
- the posts 14, 16, 18 and 20 are telescopic. They are each about hydraulic piston cylinder assemblies 22 of the Transport position pivoted in a working position.
- the vehicle crane 10 consists of a vehicle 12 designed as an 8-axle vehicle is.
- a driver's cab 26 is arranged in front of the chassis with the eight axles.
- the supports 14, 16, 18 and 20 pivoted in the middle area of the Vehicle 12, the supports 14, 16, 18 and 20 pivoted.
- a revolving crane 28 is arranged, on which a revolving stage 30 (see Figure 3 and Figure 5) can be placed.
- the legally permitted total height for the vehicle is 12 4 m.
- the hinged Supports 14, 16, 18 and 20 are telescopic, and as shown in FIGS. 3 and 4, box-shaped with a substantially rectangular cross-section are formed.
- the vehicle 12 moves without a turntable and without built-up crane structure to the site.
- the revolving stage 30 possibly after previous assembly of attachments, such as Catwalks 32 and a rise not shown here (see Figure 5) put the turntable 28.
- the touchdown takes place via a separate vehicle crane 50.
- the vehicle crane takes the turntable 30 from a low loader.
- the large vehicle crane 10 is rectangular positioned to the vehicle crane 50 and the turntable 30 is lowered and via a quick connection or quick connection not shown here connected to the chassis frame.
- the crane 50 serving for mounting is supported under the folding spaces the large vehicle crane 10 is positioned.
- the catwalks 32 and possibly other attachments such as a rise or the like are connected via bolts with the turntable 30, before then with these add-on parts are placed together on the large vehicle crane 10 and with This is connected via the quick connection.
- the crane structure can then be connected to the revolving stage be bolted.
- the vehicle crane 10 Due to the high folding supports the vehicle crane 10 reaches a very high Stiffness, so that much higher loads can be achieved.
