Tower crane

1. A tower crane comprising:

a crane tower and a jib mounted thereon; and

a counter-jib,

wherein a length of the counter-jib is defined by a number of counterweights;

wherein a first counterweight is mounted to a free end of a steel structure of the counter-jib, and any other counterweights are directly connected to the first counterweight or to one another;

wherein at least one counterweight of the number of couterweights comprises at least one cantilevered panel to retain the at least one counterweight at a respective bearing point of the steel structure of the counter-jib or a further counterweight;

wherein the at least one counterweight additionally comprises at least one tab or at least one rigid hook establishing a tensile connection with the steel structure or the further counterweight; and

wherein at least one attachment rod extending transversely to a jib direction is provided at the steel structure or the further counterweight as a counter-element for the at least one tab or at least one rigid hook.

2. The tower crane according to claim 1 , wherein at least two counterweights of the number of counterweights in a counter-jib direction are mounted successively.

3. The tower crane according to claim 1 , wherein the bearing point of at least one counterweight is formed by a recess of an upper side of the counterweight.

4. The tower crane according to claim 3 , wherein a continuous platform is formed when successively arranging multiple counterweights through the recess.

5. The tower crane according to claim 4 , wherein the counterweights are identical.

6. The tower crane according to claim 4 , wherein at least one of the counterweights is surrounded at least partially by a steel frame.

7. The tower crane of claim 4 , wherein at least one part of the counterweights differ in at least one of thickness, perimeter, shape, or type of material used.

8. The tower crane of claim 3 , wherein the recess extends in the jib direction continuously through the counterweight.

9. A counterweight for ballasting a counter-jib of a tower crane, wherein the counterweight comprises at least one cantilevered panel to retain the counterweight on a horizontal bearing point, as well as at least one tab or at least one rigid hook, for establishing a tensile connection with an attachment rod;

wherein the counterweight comprises a bearing point for retaining the cantilevered panel of a further counterweight, wherein the bearing point is formed by a recess on an upper side of the counterweight and the recess extends in a mounting position in a jib direction continuously on the upper side through the counterweight;

wherein the counterweight is provided with a frame enclosing a ballast element; and

wherein the frame provides support to the ballast element.

10. The counterweight according to claim 9 , wherein the frame enclosure is made of steel.

11. The counterweight according to claim 9 , wherein the counterweight does not have a cleat.

12. The counterweight of claim 9 , wherein the cantilevered panel is in the form of at least one cleat.
