Definitions
- the present invention relates to a tower crane with a tower which carries a boom and a counter-jib, wherein from a tower top a boom bracing is guided to the boom and the counter-jib.
- first tie bar may be struck at about one third of the total boom length and a second tie bar at about two thirds of the total boom length.
- tower cranes have become popular, which dispense with such a boom bracing and instead reinforce the boom itself so far that it can absorb the forces as a cantilever beam.
- Such towerless tower cranes are sometimes referred to as "flat-top” cranes or “topless” cranes or “hammer-head” cranes because they lack the towering tower above the boom Lower height and a simple assembly process.
- the document EP 2 041 017 B1 shows such a centerless tower crane and proposes for this purpose an assembly method which is intended to facilitate the construction of the crane.
- the document DE 10 2005 018 522 B4 also shows such a centerless tower crane, wherein the total non-tensioning bending beam cantilever should have several bearing points to be mounted at different locations on the upper tower end can, so that the counter-jib once a greater length and once a smaller length gets.
- Another towerless tower crane is known for example from the document GB 14 93 715 or the brochure "The EC-B flat-top cranes" of the Liebherr-Werk Biberach GmbH.
- a comparison between a guyed tower tower crane with a spire and a centerless Fiat Top-Kran shows the font ES 22 64 334 A1. Therein it is proposed to mount the counterjib a bit higher than the boom in order to further simplify the assembly.
- Tower cranes in which the boom bracing is kept relatively short, are known for example from the Spanish company JASO under the type designation H series, for example model variant J560. There is the boom to the Jib tip towards relatively solid trained to intercept the bending forces and moments that can be adjusted, which makes the crane as a whole relatively heavy and massive.
- the present invention has the object to provide an improved tower crane of the type mentioned, which avoids the disadvantages of the prior art and further develops the latter in an advantageous manner.
- a low overall height and ease of assembly is to be achieved without buying this by high component weights and excessive component geometries of the jib parts.
- the vertical boom extension of the respective boom part of the lower edge is meant to its upper edge, which may be the vertical spacing of lower flange to upper flange in a design of the boom parts as a framework with upper and lower chords.
- the cantilevered from the tower boom height of the unbent outer cantilever part which acts as a bending beam, can be formed in one or more stages reduced, with a multi-stage tapering of the boom height a plurality of conically tapered boom pieces can be provided between each of which a non-tapering, in the height constant remaining boom piece can be provided.
- a continuous taper of the boom height which may extend over about the entire length of the unbent, outer boom part or at least a substantial piece thereof, for example via more than 50% or more than 75% of the length of the unseeded outer branch.
- the outer, unstressed boom part can taper continuously and evenly as far as the boom tip in the boom height.
- a reduction in boom height is provided.
- each rigid boom parts which may be formed, for example, as lattice girder composed, for example, bolted or otherwise rigidly built together
- the aforementioned, conically tapered boom section for example, directly connect to the guyed inner boom part or grown on it his.
- at least one boom part of constant, relatively high boom height can first be attached to the inner, braced boom part, and then the tapered boom piece can be attached to it.
- the conically tapered jib part several further jib parts can be grown than on the inner side of said conical jib part.
- a part of the unbent outer cantilever part tapered in the boom height may amount to more than a quarter or more than one-third or even more than half of the entire length of the outer, unbalanced cantilever part, wherein, as said, the entire outer, unbalanced cantilever part, for example, continuously conically tapers can be.
- the aspect ratio between its inner portion of greater height and its outer portion of reduced height may be chosen differently, with the inner boom portion of greater height tending to be shorter than the outer portion of reduced height.
- other aspect ratios may also be used in which the inner boom section of greater height may be longer than the reduced height outer landing section, where the smaller and larger height sections respectively refer to sections of the outer, unbucked boom section.
- the inner boom section of greater height (of the outer, unbucked boom section) may constitute about 15% to 60%, preferably 30% to 40% of the total length of the outer, unbiased boom section while the reduced boom outer boom section has a length of 40% to 85 ° %, in particular about 60% to 70% of the entire length of the unseeded outer boom part may have.
- the amount of boom height reduction can be variously dimensioned, with, for example, a height reduction of at least 20% or at least 30% or at least 40% being provided, i. the boom of smaller height has a boom height of less than 80% or less than 70% or less than 60% of the boom height of the boom of greater height. If only one conically tapering boom part is provided, its height at the outer end may be, for example, less than 80% or less than 70% or less than 60% of its height at the inner end.
- the inner, taut part of the boom can be kept even shorter than the aforementioned 40% of the total length of the boom.
- the first third or the first quarter of the boom can be guyed, i. the anchor point of the outermost guy rope may be at 25% or 33% of the total length of the boom (if the length count on the tower is commenced, i.e. the boom portion pivoted length is 0% and the cantilever tip is 100%).
- the bracing can also be further shortened so that the outermost bracing point is, for example, only 20% or 15% of the boom length.
- the outermost anchor point - may be about 20-25 m.
- the height of the spire, from which the bracing is guided to the boom, can advantageously be kept very small in order not to increase the height of the crane significantly above the upper edge of the boom.
- the spire may be less than twice the boom height.
- the top end of the spire may be about 20% to 100% or 40% to 60% of the boom height above the boom top boom when 100% is the maximum boom height. If, for example, the maximum boom height is 2.5 m (which is only to be understood as a simple calculation example), the spire can be, for example, 50 cm to 2.5 m or 1 m to 1.5 m above the upper edge of the jib.
- the said spire may extend approximately vertically above the tower and, as it were, continue vertically upwards.
- the spire can also be formed inclined, for example, at an acute angle to the longitudinal axis of the tower to the rear of the counter-jib arranged tilted or tilted forward to the boom to be arranged.
- the bracing can also be performed back to the counter-jib and posted there before the ballast weight on the counter-jib.
- Due to the flat design of the bracing can advantageously be a hoist, in particular a hoist winch with drive and possibly gear, be arranged on the counter-jib, in particular in an inner side of the ballast weight adjoining jib section, which is adjacent to the ballast weight.
- the hoist between ballast weight and the attachment point of the bracing can be arranged on the counter-jib. This results in an overall positive distribution of the total weight and the counterweight compensation to which said hoist winch arrangement contributes.
- the hoist winch or the hoist can be spaced further from the tower than the attachment point of the bracing.
- the inner, jibed cantilever part can also change over the length Boom height own.
- the inner, braced boom part can also have at least one conically tapered boom part, which can form, for example, the pivot piece with which the boom is articulated on the tower.
- the tapered in the boom height portion of the inner, jawed cantilever part may advantageously be at least 30% or more than 40% of the total length of the inner, jawed cantilever part.
- the taper of the boom height of the inner, braced boom member may be formed in one or more stages.
- the inner, braced boom part may also be steplessly tapered continuously over substantially its entire length in the boom height, the boom height tapering towards the tower.
- the boom can be advantageously designed as a truss boom, in which a plurality of longitudinal straps are connected by cross braces.
- the boom can be designed as a three-jib with a top flange and two bottom straps as longitudinal straps.
- the bracing on the one hand and the boom on the other hand may be formed of different materials.
- the jib parts in particular their upper and lower chords, can advantageously be made of fine grain structural steel, whereby swelling loads can be well absorbed.
- the bracing could basically also be formed of steel, in particular a steel rod or a steel cable.
- the bracing can be constructed of plastic fibers, in particular of a high-strength fiber rope or in the form of laminated, plastic fiber-reinforced bracing rods.

- the boom part 3k which conically tapers towards the cantilever tip can be adjoined on the inside by a boom part 3gh of relatively greater height and on the outside by a boom part 3kh of relatively smaller boom height, the said boom height being in particular the height of the boom 3k correspond to the inner end of the conically tapered jib part and the said smaller height may correspond to the height of the outer end of the conical jib part 3k.
- the inner boom part 3gh with a relatively greater height can tend to be shorter than the outer boom part 3kh with a relatively smaller boom height.
- the length ratios of the jib parts with larger and smaller height may have a length gh, which may be in the range of 15% to 60%, in particular about 30% to 40% of the total length l 3a of the outer, unbalanced jib portion 3a.
- the outer boom part 3kh with a relatively smaller height may have a length bkh which may be in the range of 40% to 85%, in particular about 60% to 70% of the total length of the outer, unbalanced boom part 3a, cf.

- the outer, unbalanced boom part 3a continuously reduced or tapered substantially over its entire length, ie from the pivot point 12 of the bracing 9 to the boom tip out in the boom height.
- the outer boom part 3a may each comprise two boom parts of greater height, two boom parts of smaller height and the said conical boom part.
- the height level at which the boom height of the outer, unbalanced boom member decreases but also be moved further inward, for example, such that on the inside only a boom part of greater height and outside two boom parts smaller height to the conical boom part connect.
- the inner, braced boom part 3i can also have at least one boom part 3k that tapers in the boom height AH, with the boom height AH here decreasing towards the tower 2.
- Said conical jib part 3k of the inner jigged jib part 3i can in particular form the articulation piece of the jib 3 with which the jib 3 is articulated on the tower 2.
- the length of the tapered inner cantilever part may advantageously be more than 25% or more than 33% and also about 50% of the length of the inner, cantilevered cantilever part 3i.
