Portal crs. α for laying tracks

The innovation concerns a gantry crane for laying Tracks, consisting of two each with a pair of supports and Portals formed by a portal cross member, which are connected to one another by a longitudinal beam carried by the portal cross members are obscured.

Such P03 "'ilkräne are limited in their outer height by a light gauge, such as is used in the Federal Railroad. J .e maximum Durchfe'irtshöhe by such PORTP-llcran is determined by the construction even thickness of the components

It is e? . Such a porta3.1r ^ an bekar ^ .t, which however has the disadvantage has that its maximum height does not allow unloading of the uppermost sleeper sohichi approved according to the clearance profile on a trolley is sufficient. The top layer

must therefore first be unloaded separately before the bar crane can go into action at the place of work.

It is the task of the innovation to create a gantry crane with which the topmost crane can also be unloaded through the clearance profile authorized shift at the workplace is possible.

A gantry crane of this type is characterized according to the tower in that the traverse at the connection point with the portal cross member on a fraction of its other Height is cranked.

Further features and practicalities of the innovation emerge from the accompanying figures and the description of a

™ exemplary embodiment.

From the figures show:

FIG. 1 is a perspective view of a gantry crane with a longitudinal traverse;

FIG. 2 shows a section through a portal with a cranked longitudinal traverse.

FIG. 1 shows a gantry crane with a gantry crane pair 4, 5, which is connected by a longitudinal traverse 3 and consists of Supports 1 and gantry cross members 2. This gantry crane moves on auxiliary rails laid out on the side over a loaded one Transport trolley on which sleepers to be laid are stacked in layers. The sleepers are then attached to the traverse Devices provided for this purpose (not shown here) attached, simultaneously lifted and then driven to the point where they are to be relocated. After the new sleepers have been laid down, the gantry crane grabs the crossbars Grippers provided for this purpose lift a piece of the old, replaceable track made of rails and sleepers

and drives it on specially designed trolleys. To when the old G-leisstück is set down, a Set of new sleepers transported.

The load height of the sleepers is determined by a clearance profile. The maximum external height of the portals is, however, also limited to the top, as it must be avoided that there is contact with electrical overhead lines or else, that the portals come up against bridges or the like. The longitudinal traverse of such a gantry crane is around 24 m long and must have a minimum width because of the necessary stability. In the design according to the innovation keep the width of the longitudinal traverse, only at the conn? It is cranked out at the point of connection with the portal cross member (Fig. 2) that the traverse is offset by about 35 cm upwards.

The resulting clearance height enables unloading even at the top of the clearance profile Threshold layer.

Eb should also be noted that on the short cranked Provide the necessary static strength is achieved by low stiffening agents, while for a truss The same load-bearing capacity with a width that is equally small over the entire length requires considerable stiffening means would be.
