Abstract

The present invention relates to a method for transferring a tower crane with a mobile crane, in particular crawler crane, wherein the mounted tower crane is lifted by means of the lifting cable of the mobile crane, in order to transfer the same to the target site, and the tower crane is stabilized by means of one or more connecting points between mobile crane boom and crane tower.

Claims

1. A method for transferring a tower crane with a mobile crane, in particular crawler crane, wherein the mounted tower crane is lifted by the lifting cable of the mobile crane, to transfer the same to the target site, and during transfer the tower crane is stabilized by one or more connecting points between mobile crane boom and crane tower.

2. The method according to claim 1, wherein during the lifting movement the crane tower is guided in lifting direction by at least one of the one or more connecting points, which comprises a guide bearing.

3. The method according to claim 1, wherein via the connecting points in the region of the tower tip the tower crane is connected with the boom tip of the crawler crane and/or in the region of the tower base is connected with the boom articulation piece of the crawler crane, and preferably at least the connecting point in the region of the tower tip comprises a guide bearing.

4. The method according to claim 1, wherein the one or more connecting points are articulated, in particular rotatable about a horizontal axis of rotation, preferably vertically to the luffing plane of the mobile crane, and the articulated connection is seated at the mounting point of the connecting point with the mobile crane boom and/or at the mounting point with the crane tower.

5. The method according to claim 1, wherein the position of the longitudinal axis of the tower crane taken up is controlled/regulated, in particular maintained almost vertical, by an adaptation of the luffing angle of the mobile crane boom and/or an adaptation of the distance between mobile crane boom and crane tower by at least one variable-length connecting point.

6. A connecting frame to be mounted on a crane tower for carrying out the method according to claim 1, wherein the frame encloses the circumference of the crane tower, in particular of an individual lattice piece, and the frame ideally includes one or more plain bearings and/or at least one articulated dumper.

7. The connecting frame according to claim 6, wherein the connecting frame comprises one or more fastening points for connection with a mobile crane boom, in particular fastening points for forming an articulated connection with the mobile crane boom, preferably with horizontal axis of rotation, which particularly preferably extends transversely to the luffing plane of the mobile crane.

8. A take-up means to be mounted on a mobile crane boom for fastening a connecting frame according to claim 6.

9. The take-up means according to claim 8, wherein the take-up means is designed in the form of a swivel arm which is pivotally mountable on the mobile crane boom, in particular on the boom foot, and preferably can be articulated to at least one said connecting frame.

10. The take-up means according to claim 9, wherein the swivel arm is variable in length, for example by a telescoping mechanism.

11. The take-up means according to claim 9, wherein at least one support cylinder is provided for fixing and/or adjusting the swivel angle with respect to the mobile crane boom.

12. The take-up means according to claim 8, wherein the take-up means is rigidly mountable on the boom head of a mobile crane and comprises one or more connecting points for the articulated connection with the connecting frame.

13. A tower crane with at least one connecting frame according to claim 6.

14. A mobile crane, in particular a crawler crane, with at least one take-up means according to claim 8.

15. A system comprising at least one tower crane and at least one mobile crane according to claim 14.

16. The method according to claim 2, wherein via the connecting points in the region of the tower tip the tower crane is connected with the boom tip of the crawler crane and/or in the region of the tower base is connected with the boom articulation piece of the crawler crane, and preferably at least the connecting point in the region of the tower tip comprises a guide bearing.

17. The method according to claim 16, wherein the one or more connecting points are articulated, in particular rotatable about a horizontal axis of rotation, preferably vertically to the luffing plane of the mobile crane, and the articulated connection is seated at the mounting point of the connecting point with the mobile crane boom and/or at the mounting point with the crane tower.

18. The method according to claim 3, wherein the one or more connecting points are articulated, in particular rotatable about a horizontal axis of rotation, preferably vertically to the luffing plane of the mobile crane, and the articulated connection is seated at the mounting point of the connecting point with the mobile crane boom and/or at the mounting point with the crane tower.

19. The method according to claim 2, wherein the one or more connecting points are articulated, in particular rotatable about a horizontal axis of rotation, preferably vertically to the luffing plane of the mobile crane, and the articulated connection is seated at the mounting point of the connecting point with the mobile crane boom and/or at the mounting point with the crane tower.

20. The method according to claim 17, wherein the position of the longitudinal axis of the tower crane taken up is controlled/regulated, in particular maintained almost vertical, by an adaptation of the luffing angle of the mobile crane boom and/or an adaptation of the distance between mobile crane boom and crane tower by at least one variable-length connecting point.
