Bei dieser Einrichtung ist das Gelenkparallelogramm-System von oberen und unteren Lenkern gebildet, wobei die jeweils oberen Lenker und die jeweils unteren Lenker miteinander mittels Träger bzw. Verbindungsstangen verbunden sind. Das Tragarmsystem wird von einem im Grundriß U-förmigen, eine Gießpfanne umgreifenden Rahmen gebildet, an dessen freien Enden die Gießpfanne abgestützt ist und an dessen die Schenkel des U verbindenden Querträger, der als Kastenträger ausgebildet ist, ein Druckmittelzylinder angreift, mit dessen Hilfe das Tragarmsystem heb- und senkbar ist.

At this box girder are also the upper links of the Articulated parallelogram system.
Die Vielzahl der Querträger bzw. Verbindungsstangen bedingt eine schwere, materialaufwendige Konstruktion, die dementsprechend teuer ist. Zudem ist die bekannte Konstruktion nur schwer von oben zugänglich, so daß ein Austausch der Druckmittelzylinder im Reparaturfall mittels eines Kranes von oben kaum durchführbar ist, ohne die Trageinrichtung in ihre einzelnen Elemente zerlegen zu müssen. The large number of cross members or connecting rods requires one heavy, material-intensive construction, which is accordingly expensive. In addition, the known construction is difficult to access from above, so that an exchange of the pressure cylinder in the case of repair by means of a Crane from above is hardly feasible without the carrying device in their having to dismantle individual elements.

mittels eines Schwenkgelenkes abgestützt ist, wobei das Schwenkgelenk
fluchtend zu den an den vom Drehsockel abgewandten Enden
angeordneten Gelenken der oberen Lenker liegt. According to the invention, this object is achieved by

The connecting the pressure cylinder 19 to the crossbeam 26 Swivel joint 38 is arranged so that its bearing axis 39 with the Axes 40 of the two upper links 20, 21 each with a support arm 31, 32 connecting joints 41 is aligned and the line of action 42 of the pressure cylinder 19 caused by the imaginary force horizontal connecting line of the upper links 20, 21 with the Joints 41 connecting support arms 31, 32 runs. This will make the upper handlebars 20, 21 only subjected to train, so that they weight and can be designed to save costs.
Um dies in einfacher Weise konstruktiv verwirklichen zu können, sind die oberen Lenker 20, 21 von der Seite gesehen im wesentlichen L-förmig gestaltet, wobei ein erster Arm 43 des L, der einerseits am Ständer 13, 14 und andererseits am Tragarm 31, 32 angelenkt ist, sich parallel zum jeweiligen unteren Lenker 22, 23 erstreckt und ein zweiter Arm 44 des L sich rechtwinkelig zu dem ersten Arm 43 des L vertikal nach oben erstreckt. An dem oberen Ende des zweiten Armes 44 ist der sich horizontal zum gegenüberliegenden oberen Lenker 20, 21 erstreckende und sich parallel zu den horizontalen Achsen 40, 45, 46, 47 der Gelenke 29, 36, 41 der Gelenkparallelogramme 24, 25 erstreckende Querbalken 26 angeschweißt. Verstärkungsrippen 48 dienen zur Versteifung der von den oberen Lenkern 20, 21 und den Querbalken 26 gebildeten U-förmigen Baueinheit 27. In order to be able to implement this constructively in a simple manner, the upper link 20, 21 seen from the side substantially L-shaped designed, with a first arm 43 of the L, which on the one hand on the stand 13, 14 and on the other hand is hinged to the support arm 31, 32, parallel to respective lower link 22, 23 extends and a second arm 44 of the L extends extends vertically upward at right angles to the first arm 43 of the L. At the upper end of the second arm 44 is horizontal to the opposite upper links 20, 21 extending and parallel to the horizontal axes 40, 45, 46, 47 of the joints 29, 36, 41 of the Joint parallelograms 24, 25 extending crossbeams 26 are welded on. Reinforcing ribs 48 serve to stiffen the upper links 20, 21 and the crossbar 26 formed U-shaped structural unit 27.
Durch eine solche Gestaltung dieser Baueinheit 27 ist es möglich, in einfacher Weise das Schwenkgelenk 38, mit dem der Druckmittelzylinder 19 am Querbalken 26 angelenkt ist, unterhalb des Querbalkens 26 an diesem zu befestigten, so daß der Querbalken 26 nicht durch Ausnehmungen geschwächt ist und ein Fluchten des Schwenkgelenkes 38 in jeder Position der Lenker 20, 21, 22, 23 mit den Gelenken 41 sichergestellt ist. By designing this structural unit 27 in this way, it is possible in simply the swivel joint 38 with which the pressure medium cylinder 19 is hinged to the crossbar 26, below the crossbar 26 on this to be attached, so that the crossbeam 26 is not through recesses is weakened and an alignment of the pivot joint 38 in every position the handlebars 20, 21, 22, 23 with the joints 41 is ensured.
Der Ausbau eines Druckmittelzylinders 19 gestaltet sich besonders einfach, da es lediglich notwendig ist, das Gelenkparallelogramm-System 17 entweder mit dem defekten Druckmittelzylinder selbst oder mittels eines externen Hubmittels anzuheben und den Druckmittelzylinder mittels eines Kranes nach oben durch den freien Raum zwischen dem Querträger 26 und den beiden Lenkern 20, 21 von der Trageinrichtung zu entfernen. The expansion of a pressure medium cylinder 19 is particularly simple, since it is only necessary to use the joint parallelogram system 17 either with the defective pressure cylinder itself or by means of a to raise external lifting means and the pressure cylinder by means of a Crane up through the free space between the cross member 26 and to remove the two links 20, 21 from the support device.
