Die Verbindung der einzelnen Turmstücke untereinander erfolgt über schnell zusammenschraubbare Stoßverbindungen, wobei es wesentlich ist, daß sich an den Eckpfosten durchlaufende Führungsflächen für die Führungsrollen 15 ausbilden. Für die genaue senkrechte Ausrichtung des Montageturmes 6 ist die Betätigung der Gewindespindeln 9 erforderlich.The assembly tower in the middle of the mast can be set up quickly and easily. Auxiliary roles are attached to the mast top 1, with their help and using of auxiliary ropes brought the individual within the mast base 2 Tower sections raised and into those required for connection to other tower sections Position. The connection between the individual tower sections takes place via quickly screwable butt joints, whereby it it is essential that continuous guide surfaces for the Form guide rollers 15. For the exact vertical alignment of the assembly tower 6, the actuation of the threaded spindles 9 is required.

In Fig. 3 ist eine Seitenansicht der Masterhöhungseinrichtung mit angehobenem Mastoberteil dargestellt und zeigt den Verfahrensschritt, bei dem ein vorbereiteter, nicht gezeigter Mastzwischenschuß bei in Betrieb befindlichen elektrischen Leitungen zwischen Mastoberteil 1 und Mastunterteil 2 montiert werden kann. Diesem Verfahrensschritt voraus geht die Demontage des in Fig. 1 gezeigten Mastzwischenschusses 5 und die anschließende vertikale Verschiebung des mit den Heberahmen 11, 12 verbundenen Mastoberteiles 1 längs des Montageturmes 6 nach oben. Hierzu wird das Hebeseil 25 durch das Zuggerät 29 eingefahren, wodurch sich die Seilausgleichrollen 28 vertikal nach unten bewegen. Als Gegenbewegung zur vertikalen Abwärtsbewegung der Seilausgleichrollen 28 ergibt sich über die oberen Zugausgleichseile 26 und die Seilumlenkrollen 27 eine vertikale Aufwärtsbewegung der Heberahmen 11, 12 mit dem Mastoberteil 1.In Fig. 3 is a side view of the master elevation device with the raised Mast top part shown and shows the process step in which a prepared, Intermediate mast intercept, not shown, with electrical lines in operation can be mounted between the upper mast part 1 and lower mast part 2. This The process step is preceded by the dismantling of the intermediate mast section shown in FIG. 1 5 and the subsequent vertical displacement of the with the lifting frame 11, 12 connected mast part 1 along the assembly tower 6 upwards. For this the lifting rope 25 is retracted by the traction device 29, whereby the rope compensation rollers 28 move vertically downwards. As a counter movement to the vertical downward movement the rope balancing rollers 28 result from the upper tension balancing ropes 26 and the cable pulleys 27 a vertical upward movement of the lifting frame 11, 12 with the mast top 1.

Nach erfolgter Montage des Mastzwischenschusses werden die Hebemittel und die Hebevorrichtung demontiert. Da der Montageturm 6 wie bereits erwähnt gemäß dem Baukasten-Prinzip aus mehreren einzelnen Turmstücken zusammengesetzt ist, gestaltet sich auch die Demontage wie die Montage mit Hilfe der am Mastoberteil befestigen Hilfsrollen und Hilfsseilen relativ einfach. After the intermediate mast section has been installed, the lifting equipment and the Disassembled lifting device. Since the assembly tower 6, as already mentioned, according to the The modular principle is composed of several individual tower sections the disassembly as well as the assembly with the help of the mast upper part Auxiliary rollers and auxiliary ropes are relatively simple.

In Fig. 9 ist eine Alternative hinsichtlich der Abstützung der Hebevorrichtung dargestellt. Bei dieser Variante entfallen Fundamentkreuz 7, Fundamentplatten 8 und Stützholme 10. Die Abstützung des Montageturmes 6 auf dem Untergrund erfolgt vielmehr über eine zentrale Fundamentplatte 31. Das untere Turmstück oder auch mehrere untere Turmstücke sind über zahlreiche seitliche Abstützungen 32 mit dem Mastunterteil 2 verbunden, welches selbst über die Mastfundamente 3 verankert ist. Die Befestigung der Masteckstiele 4 des Mastoberteiles 1 an mittels Führungsrollen 15 längs des Montageturmes 6 beweglichen Heberahmen 11, 12 ist wie unter den vorstehenden Figuren beschrieben.9 shows an alternative with regard to the support of the lifting device. In this variant, foundation cross 7, foundation plates 8 and Support bars 10. The assembly tower 6 is supported on the ground rather, via a central foundation plate 31. The lower tower section or also several lower tower sections are with numerous lateral supports 32 with the Lower mast part 2 connected, which is itself anchored via the mast foundations 3. The attachment of the mast corner stems 4 of the mast top part 1 by means of guide rollers 15 along the assembly tower 6 movable lifting frame 11, 12 is as under the described above figures.

In den Fig. 10, 11, 12 sind Alternativen hinsichtlich der Hebemittel dargestellt. Die erste Variante gemäß Fig. 10 benötigt vier Hebeseile 25, die von vier Greifzügen 29 ausgehend und über insgesamt mindestens vier Seilumlenkrollen 27 mit den vier Ecken des oberen Heberahmens 12 verbunden sind. Beim Ausführungsbeispiel gemäß Fig. 10 sind insgesamt zwölf Seilumlenkrollen 27 vorgesehen. Die Verbindung des Heberahmens 12 an den Masteckstielen 4 und die längs der Eckpfosten des Montageturms 6 gleitenden Führungsrollen 15 des Heberahmens sind erkennbar.10, 11, 12, alternatives with regard to the lifting means are shown. The The first variant according to FIG. 10 requires four lifting ropes 25, which are connected by four gripping cables 29 starting with a total of at least four rope pulleys 27 with the four Corners of the upper lifting frame 12 are connected. In the embodiment according to 10, a total of twelve cable pulleys 27 are provided. The connection of the lifting frame 12 on the mast posts 4 and along the corner posts of the Assembly tower 6 sliding guide rollers 15 of the lifting frame can be seen.

Die Variante gemäß Fig. 11 hat gegenüber der Variante gemäß Fig. 10 den Vorteil, daß lediglich zwei Greifzüge 29 erforderlich sind. Die beiden Greifzüge sind über zwei Hebeseile 25 mit zwei Seilausgleichrollen 28 verbunden. Die Seilausgleichrollen 28 führen zwei Zugausgleichseile 26, deren Enden über nicht dargestellte, am oberen Turmstück des Montageturmes 6 befestigte Seilumlenkrollen mit den vier Ecken des Heberahmen verbunden sind.The variant according to FIG. 11 has the advantage over the variant according to FIG. 10 that that only two grips 29 are required. The two reachings are over two lifting ropes 25 connected to two rope compensation rollers 28. The rope compensation rollers 28 lead two tension compensation cables 26, the ends of which are not shown, at the top Tower section of the assembly tower 6 attached rope pulleys with the four corners of the lifting frame are connected.
