Definitions
- the invention relates to a luffing jib tower crane, the counter jib Turmpitz system is divided into trusses.
- Tower cranes comprise a crane base from which a tower extends upwards. At an upper portion of the tower, a boom and possibly a counter-jib is attached. Tower cranes are known for example from the patent DE 35 10 116 C2.
- a revolving frame is mounted at the top of the tower. Above the revolving frame, there is disposed a counterjib tower spike system to which is connected a boom whose angle to the horizontal plane is changeable.
- the angle of the jib to the horizontal plane is determined by a seesaw rope, the length of which can be adjusted via a rope pull-in unit.
- a top-rotating luffing jib tower crane which has a tower top designed as a transport and assembly unit.
- the disadvantage of this solution is that it is a very heavy component in this spire, the size and weight of which cause difficulties during transport, assembly and disassembly.
- the size of the spire also makes extreme accuracy in the construction of countersteer Turmspitz system required because even the smallest deviations are correctable only with great effort.
- the invention has for its object to provide a top-rotating luffing jib tower crane available, the counter-jib Turmspitz system avoids the disadvantages of the known counter-jib tower Spitz systems described.
- the counter-jib-tower spike system is divided into three trusses with the features designated in claim 1. Further embodiments are the subject matter of the subclaims or described below.
- the subdivision of the counterjib tower spike system according to the invention in trusses provides significantly lighter components than known from EP 0 298 391 B1.
- the connections between the bars that form the trusses can be articulated, creating greater tolerances in the assembly.
- the manufacturing costs are lower because the trusses can be made from prefabricated profiles, requiring less welding work.
- the invention proves to be particularly advantageous if the luffing jib tower crane is one in which the angle of the jib to the horizontal plane is determined by a seesaw rope whose length can be adjusted by means of a rope pulling-in unit.
- a particularly advantageous embodiment of the invention provides that the Seileinziehwerk is attached to an element (spar) of the spire and that a roller block with sheared Wippseil of the Hauptabschreib the boom releasably and for the transport of this element (Holms) of the spire lattice fixed, but solvable connected to this.
- This element of the spire tower can be designed as a transport and assembly unit, so that no manual cable shingles during construction of the crane at the site is more necessary.
- FIG. 1 shows the counterjib tower spike system of an inventive
- Figure 2 shows a belonging to the spire lattice spar in
- FIG. 1 shows a part of the upper region of a luffing jib tower crane according to the invention in two different boom positions.
- a rotating frame 2 At the top End of the tower 1, a rotating frame 2 is arranged.
- the counter-jib-towering system 3 Above the rotating frame 2 is the counter-jib-towering system 3, with which the boom 4 is connected, the angle to the horizontal plane is determined by a seesaw 5, the length of which can be adjusted via a cable pulling 6.
- the counter-jib towering system 3 is divided into a revolving frame truss 7, a counter-jib truss 8, and a spire truss 9, each having three sides from the illustrated lateral perspective.
- the rotating frame truss 7 is located below the boom, ie below the point at which the boom 4 is connected to the counter-jib towering system 3.
- the rotating frame truss 7 sets with its underside in a horizontal plane above the horizontal rotating frame 2 at.
- the rocker truss 8 has a common side with the spire lattice truss 9 and the rotating frame framework 7.
- the rocker rope 5 is under multiple Seileinscherung over pulleys 10 at the top of the spire 9 beam Holmes 9a and on the roller block 11 to a fixed point 12 at the top of Holmes 9a led.
- the pulleys 10 and the cable pulling 6 are connected both during transport and in the operating state with the spar 9a.
- the roller block 11 is fixed during transport to the spar 9a. In the operating state of the crane mounted on the construction site, the roller block 11, after being detached from the beam 9 a, is connected to the main guy 13 of the boom 4.
- FIG. 2 shows the spar 9a belonging to the spire framework in the transport state. Both the Seileinziehwerk 6 and the roller block 11 are attached to the spar 9a.
