  • the present invention relates to a vehicle crane with a winch arranged on the superstructure, in particular a hoist winch.
  • a vehicle crane usually comprises the upper carriage rotatably mounted on a lower carriage, wherein the winch is arranged on the revolving platform frame of the upper carriage.
  • a boom is usually arranged on the superstructure, which can be flipped over hydraulic cylinders.
  • the hoist winch serves to lift the hoist when lifting a load. Likewise, several hoisting winches can be provided for this purpose.
  • Object of the present invention is therefore to provide a vehicle crane available, which complies with the transport regulations in terms of maximum height and axle loads. Furthermore, it is an object of the present invention to provide a vehicle crane, which can independently establish operational readiness on many construction sites without auxiliary crane.
  • this object is achieved by a vehicle crane according to claim 1.
  • the vehicle crane for this purpose has means for lifting and / or lowering the winch.
  • the vehicle crane according to the invention can independently establish readiness for use on the construction site without the winch having to remain in its operating position during transport.
  • the winch can be releasably connected to the vehicle crane, in particular to be removed for transport by the means for raising and / or lowering the winch and then to be able to be re-assembled.
  • the winch can be reduced by the means for raising and / or lowering the winch before transport, so that the height and weight of the vehicle crane according to the invention during transport reduced accordingly.
  • the winch is then reinstalled. Both can be done by the inventive means for raising and / or lowering the winch without an auxiliary crane.
  • the winch can be lifted by means of the means for raising and / or lowering the winch from below into a revolving platform frame of the superstructure.
  • the winch can be lowered by the means for raising and / or lowering the winds again from the revolving platform frame of the superstructure. This makes it possible in a simple way to mount the winch on the construction site, without the need for an auxiliary crane would.
  • the winch can be transported to the construction site, for example via a separate transport vehicle.
  • the winch can also be used by means of an auxiliary crane from above into the revolving platform frame of the superstructure.
  • an auxiliary crane from above into the revolving platform frame of the superstructure.
  • the winch according to the invention by means of the means for raising and / or lowering the winch on the superstructure from a first position in a relation to the height direction of the vehicle crane higher operating position and / or from an operating position in a lower relative to the height direction of the vehicle crane first position movable.
  • This makes it possible to lower the winch after operation in order to comply with the maximum permissible heights of the vehicle crane during transport. Arrived at the construction site, the winch can then be raised back to its operating position. As a result, it is no longer necessary to completely disassemble the winch for transport. Nevertheless, a simple and independent making the operational readiness on the means for raising and / or lowering the winch is possible.
  • the first position is therefore a transport position of the winch on the crane.
  • the first position is a further operating position, which allows operation of the vehicle crane, in particular a full-value operation of the vehicle crane without ballast.
  • the vehicle crane can advantageously also be used in the transport position of the winch for lighter strokes such as assembly strokes, so that the transport position simultaneously represents another, optionally restricted operating position.
  • the device according to the invention has a receptacle of ballast, which simultaneously forms the means for lifting and / or lowering the winch.
  • the ballast must be arranged during the crane operation at the rear of the superstructure to form a counterweight for the boom or the load.
  • the ballast is removed from the superstructure and stored on the undercarriage or on its own transport vehicle to meet the axle loads of the undercarriage.
  • a device for receiving ballast serves this removal and receiving the ballast on the superstructure.
  • Such a device for receiving ballast is in particular from the DE 20 2005 016 815 U1 the content of which is fully incorporated in the present application. According to the invention, such a device for receiving ballast is now used to raise and / or lower the winch.
  • the means for raising and / or lowering the winch comprise a pallet, which is movable by means of lifting means in the vertical direction, wherein the winch and / or the ballast can be moved by means of the pallet in an operating position.
  • the winch or the ballast is thereby arranged on the pallet and moved by the movement of the pallet in the operating position.
  • the range is in the operating position on the superstructure bolted.
  • the pallet thus remains during operation on the superstructure and serves to hold the winch or ballast.
  • the palette has recordings, in particular adjustable recordings, on which the winch can be positioned and defined.
  • the winch is in the operating position on the bolted to the superstructure on pallet.
  • the bolted to the superstructure pallet thus serves to secure the winch in the operating position.
  • the winch is bolted to the superstructure. This allows the winch, z. B. after it has been raised to its operating position, be connected to the superstructure. Likewise, such a bolting of the attachment of the winch in the first position, in particular a transport position serve.
  • the bolting of the winch on the superstructure takes place by means of a slot, which allows a movement of the winch from an operating position to a lower position relative to the height direction of the vehicle crane first position, in particular a transport position.
  • a slot thus allows a certain movement of the winch on the superstructure, and also serves to secure the winch in the operating position and the first position.
  • the winch is in the first position, in particular a transport position, securable, in particular via a bolt which fixes the bolt in the slot, so that the vehicle crane can also be used with the winch located in the first position.
  • the first position thus represents a further operating position, so that the vehicle crane z. B. can be used to load the ballast plates or pallet independently and without auxiliary crane.
  • the winch is secured in a further advantageous manner on the bolted to the superstructure range and on the Verbolzung the slot. Another backup is not required.
  • the securing of the winch takes place automatically in the first position. This can be done by appropriate control of a latch drive, e.g. via a spring drive with corresponding control surfaces.
  • the securing of the winch is automatically released when lifted into the operating position. This can also be done via a corresponding drive.
  • the present invention comprises both a vehicle crane with only one winch, which can be raised and / or lowered by the means for raising and / or lowering the winch, also a vehicle crane with two or more winches, which according to the invention by means for lifting and / or lowering the winch can be raised and / or lowered.
  • the vehicle cranes according to the invention can also have other winches, which can not be raised and / or lowered via the means for lifting and / or lowering the winch.
  • FIGS. 1a and 1b an embodiment of the inventive means for raising and / or lowering the winch 1 is shown in different lowered positions.
  • the means in this case have a pallet 10, which can be used on ropes 11 on the revolving platform frame 4 of the superstructure and drained again.
  • This arrangement also serves to accommodate the ballast and is closer in their execution in DE 20 2006 007 486 U1 whose contents are fully referenced.
  • the pallet 10 can be pulled over the ropes 11 completely to the superstructure and bolted with this, as well as to dismantle the winch or ballast from the superstructure either on a separate transport vehicle, the floor or the undercarriage drained.
  • the lifting means for actuating the cables 11 are arranged in the revolving platform frame 4 and advantageously comprise hydraulic cylinders, which are arranged substantially horizontally.
  • the pallet 10 can be bolted to the revolving platform frame 4 in its operating position, thereby securing the winch 1.
  • the ballast, not shown, is also held above the pallet 10 on the superstructure.
  • the pallet 10 now has adjustable seats 8, on which the winch 1 can be positioned and defined via corresponding positioning elements 7. A further attachment of the winch 1 on the pallet 10 is not provided.
  • the winch is 1 in FIG. 2a shown. Down the winch 1 is set over the bolted to the revolving platform frame 4 range 10. Upwards and against tilting it is secured over the bolts 6, which engage at the Verbolz Vietnameseen 12 on the revolving platform frame 4 and in the slots 9 on the winch.
  • FIG. 2b the transport position of the winch 1 is shown, in which the pallet 10 has been drained, while the bolts 6 remain plugged.
  • the winch thereby moves first with the pallet 10 along the slots 9 down until the slots 9 sit with their upper limits on the bolt 6.
  • This transport position is again in FIG. 3 it can be seen that, in the transport position, the winch 1 has the same height as the front winch 2.
  • the winch 1 in this case has a hydraulic motor integrated in its axis of rotation, which drives the winch.
  • the winch is mounted on a support frame, which the two parallel slots 9 for bolting to the revolving platform frame 4 has.
  • the elongated holes 9 in this case have a lower Verbolzposition 6b, in which the bolts 6 are in the operating position, and an upper pin position 6a, in which the bolts are in the transport position. If the winch 1 thus lies on the receptacles 8 of the pallet 10 via the counter elements 7 in the operating position, the bolts 6 in the bolt positions 6b prevent the winch from moving upwards and to the side and thus tilting the winch.
  • the winch 1 moves downwards until the elongated holes 9 rest on the bolt 6 in the pin positions 6a.
  • the winch 1 is secured in this transport position on the bolt 50, wherein the bolt 50 via a Verbolzantrieb 51 and a drive lever 53 are moved.
  • a control surface 52 of the bolt unit is provided, on which a counter-element on the pallet 10 engages, so that the winch 1 is automatically locked in the transport position when the pallet 10 is lowered further and vice versa automatically unlocked when the winch 1 over the pallet 10 is raised.
  • FIG. 5 is once again shown in a perspective view of the pallet 10, wherein in the central region, the receptacles 8 for the winch and in the mutual edge areas ballast platforms 20 are shown for receiving ballast elements.
  • the vehicle crane according to the invention with the means for raising and / or lowering the winch 1 is equipped.
  • the means for raising and / or lowering the winch comprise a pallet 10, which in the exemplary embodiment can be raised or lowered via ropes 11 relative to the revolving platform frame 4 of the superstructure.
  • one or more further winches may be provided, which may be raised and / or lowered by the means for raising and / or lowering the winches.
  • the front winch 2 to be seen can not be automatically lowered or raised in the exemplary embodiment. However, it is anyway arranged lower than the rear winch 1 in its operating position, so that a lowering for transport is not necessary.
  • the winch 1 is now designed so that they can be used both by an auxiliary crane from above in the revolving platform frame 4, as well as from below into the revolving platform frame 4 can be lifted.
  • 10 adjustable recordings 8 are provided on the pallet on which the winches can be parked and defined. Another attachment is not necessary here.
  • bolts 6 are provided, which can be plugged into the Verbolzposition the winch 1, so that the crane can work fully. So that the bolt can be made from a safe stand, a linkage 3 is provided, via which the bolting of the winch in its working position from the top of the revolving platform frame 4 is possible.
  • the pallet 10 can be drained with the ballast and removed from the crane. As a result, however, the lower bearing of the winch 1 is removed. Since the winch 1 remains bolted in the revolving platform frame 4 and the bolts 6 are added to the winch on the slot 9, the winch lowers by a defined path (long hole length). This achieves the maximum permitted height in the STVZO area.
  • a bolt 50 is advanced, which holds the winch 1 in the lowered position.
  • the control of the bolt 50 takes place automatically via a drive 51 (spring, electric or hydraulic or other motor, etc.) and a controller.
  • a linkage is provided, which automatically advances the bolt 50 when lifting the winch 1 from the pallet 10.
