Definitions
- the present invention relates to a side support having the features of the preamble of claim 1 and a vehicle or a vehicle-mounted crane having such a side support.
- hydraulic lines can be brought to the support through or away from the support via hydraulic lines, in order to extend or retract a support leg mounted telescopically in the support. Hydraulic lines can also be provided for other purposes.
- the object of the invention is to provide a generic side support or a vehicle or a vehicle-mounted crane, in which the disadvantages discussed above do not occur.
- the at least one hydrofluoric line runs in the interior of the boom profile at least to the attachment point and through it and is thus protected against damage. There is no sagging of the at least one hose line in the area between the boom profile and support.
- FIGS. 3 to 7 represent the prior art.
- the invention is based on the FIGS. 3 to 7 explained in more detail, with those details that in the Figures 1 and 2 are shown and do not relate to the course of the at least one hydraulic line 7, of course, also apply with respect to the invention as disclosed.
- FIG. 1 shows a side arm 1 of a vehicle to be mounted on a crane not shown 2 (here: loading crane).
- a side support 1 is provided, which has two cantilevered in a boom profile 3 and extendable boom 11.
- a support 6 is arranged via an attachment point 5 and it is telescopically from each support 6 and extendable a support leg 10 is provided.
- FIG. 1 It can be seen that a hydraulic line 7 formed here as a hose line runs unprotected below the boom profile 3 up to a connection point 8, which is arranged on that side of the support 6, which faces the boom profile 3.
- FIG. 2 differs from that FIG. 1 in that the hydraulic line 7 extends over part of the path within the boom profile 3 (more precisely within the boom 11), but exits therefrom before reaching the attachment point 5 for the support 6. From the exit point to the junction 8, the hydraulic line 7 runs unprotected.
- FIG. 3 shows a side support according to the invention, wherein it stands out that no hydraulic line 7 can be seen, since they extend within the arm 11. In what way this can happen is in three different embodiments in the FIGS. 4 to 6 shown.
- the subfigures a) relate in each case to a sectional view along the line B - B of FIG. 3 , the subfigures b) on a sectional view along the line A - A of FIG. 3 and the subfigures c) to a representation of the pivoting range of the support. 6
- FIG. 3 extends the at least one hydraulic line 7 (here are somewhat more realistic two hydraulic lines 7, for example, inflow and outflow of hydraulic oil, shown) in the interior of the boom 11 to the attachment point 5 and through it and opens into a junction 8, on that side the support 6 is arranged, which is remote from the boom profile 3.
- the connection point 8 can also be arranged at a different position-possibly also elsewhere than on the support 6.
- FIG. 3 is the hydraulic line 7 also in that portion which passes through the attachment point 5, formed as a hose line.
- a larger swivel range for example, a maximum of about plus / minus 90 ° or 180 ° from a vertical position on the boom profile 3
- a rotary coupling 9 in the form of a swivel fitting per hose (rotatable up to a maximum of 180 °) is provided and after the solution FIG. 6 a rotary coupling 9 is provided in the form of a rotary distributor (unlimited rotatability).
- Rotary fittings and rotary distributor are known in the art and therefore need not be described in detail here.
- the rotary joint 9 can also be arranged at a different location than in the region of the fastening point 5.
- the rotary joint 9 could also be located at the other end or in the central region of the boom profile 3.
- FIG. 7 shows the arrangement of a detachable cover 12 in the region of the attachment point 5 and the connection point 8, which serves to protect these components.
- the cover 12 is mounted in FIG. 7b is she removed?
- the two hydraulic lines 7 serve to move the support leg 10 via the supply and removal of hydraulic oil.
- hydraulic lines 7 could be provided which serve other purposes.
- the hydraulic lines 7 lead to a connection point 8 on the support 6. Depending on the purpose of the hydraulic line 7, this can of course be solved differently.

Description
Die vorliegende Erfindung betrifft eine Seitenabstützung mit den Merkmalen des Oberbegriffs des Anspruchs 1 und ein Fahrzeug oder einen fahrzeugmontierten Kran mit einer solchen Seitenabstützung.The present invention relates to a side support having the features of the preamble of
Aus verschiedenen Gründen kann es erforderlich sein, Hydraulikleitungen aus dem Bereich des Fahrzeuges bzw. des fahrzeugnahen Bereichs der Seitenabstützung zu einer an der Stütze angeordneten Anschlussstelle hin verlaufen zu lassen. Beispielsweise kann über Hydraulikleitungen Hydrauliköl zur Stütze hin bzw. von der Stütze weg gebracht werden, um einen in der Stütze teleskopisch gelagerten Stützfuß auszufahren oder einzufahren. Hydraulikleitungen können aber auch für andere Zwecke vorgesehen sein.For various reasons, it may be necessary to extend hydraulic lines from the area of the vehicle or the vehicle-related area of the side support to a connection point arranged on the support. For example, hydraulic oil can be brought to the support through or away from the support via hydraulic lines, in order to extend or retract a support leg mounted telescopically in the support. Hydraulic lines can also be provided for other purposes.
Bisher verliefen die Hydraulikleitungen in Form von Schlauchleitungen am Auslegerprofil außen entlang und hingen nach unten hin durch. Es ist auch eine Lösung bekannt, bei welcher Schlauchleitungen innen im Auslegerprofil verlaufen, aber noch vor der Befestigungsstelle für die Stütze aus dem Auslegerprofil heraus treten und mit einer an einer fahrzeugnahen Seite der Stütze angeordneten Anschlussstelle verbunden sind.So far, the hydraulic lines in the form of hose lines on the boom profile ran along the outside and hung down towards. It is also known a solution in which hose lines run inside the boom profile, but even before the attachment point for the support out of the boom profile out and are connected to a arranged on a side of the vehicle near the support connection point.
Daraus ergibt sich die Problematik, dass die Hydraulikleitungen beschädigt werden können. Häufig ist vorgesehen, dass die Befestigungsstelle für die Stütze am Auslegerprofil als Drehgelenk ausgebildet ist. In diesem Fall sind die außen verlaufenden Hydraulikleitungen beim Stand der Technik besonders störend bzw. schadanfällig.This results in the problem that the hydraulic lines can be damaged. It is often provided that the fastening point for the support on the boom profile is designed as a swivel joint. In this case, the external hydraulic lines are particularly disturbing or prone to damage in the prior art.
Aufgabe der Erfindung ist die Bereitstellung einer gattungsgemäßen Seitenabstützung bzw. eine Fahrzeuges oder eines fahrzeugmontierten Krans, bei welchen die oben diskutierten Nachteile nicht auftreten.The object of the invention is to provide a generic side support or a vehicle or a vehicle-mounted crane, in which the disadvantages discussed above do not occur.
Diese Aufgabe wird durch eine Seitenabstützung mit den Merkmalen des Anspruchs 1 bzw. ein Fahrzeug oder einen fahrzeugmontierten Kran mit den Merkmalen des Anspruchs 13 gelöst.This object is achieved by a side support with the features of
Bei einer solchen Seitenabstützung verläuft die wenigstens eine Hydarulikleitung im Inneren des Auslegerprofils zumindest bis zur Befestigungsstelle hin und durch diese hindurch und ist so gegen Beschädigung geschützt. Es kommt zu keinem Durchhängen der wenigstens einen Schlauchleitung im Bereich zwischen Auslegerprofil und Stütze.In such a side support, the at least one hydrofluoric line runs in the interior of the boom profile at least to the attachment point and through it and is thus protected against damage. There is no sagging of the at least one hose line in the area between the boom profile and support.
