    The present invention relates to a railway crane with a first crane boom at one end, a second crane boom at its other end and a transport receiver therebetween.
    Railway cranes usually have only one crane jib. For lifting particularly heavy loads such as bridge parts, locomotives or the like. sometimes two single-arm cranes are used, which must be moved and operated as synchronously as possible in order to avoid the introduction of dangerous lateral forces in the lifting harness. Transporting the load over longer distances is only possible slowly with two single-arm cranes acting on the ends of the load, since the building up of dangerous vibrations must absolutely be avoided.
    In the fifties of the last century, double-arm railway cranes were used, in which a crane jib was mounted at the ends of a wagon, in order, e.g. To lay track yokes. The known wagon-based double-arm railway cranes, however, are unable to move a longer load to an unloading point, e.g. a pre-assembled turnout piece from its assembly point to its place of installation.

    The invention has the object to overcome the disadvantages of the known prior art and to provide a railway crane, which is suitable for particularly heavy and long loads, such as long track bumpers, pre-assembled switches or crossings or the like., And a quick and safe Procedures allowed over long distances to the place of installation.
    This object is achieved with a railway crane of the aforementioned type, which is characterized according to the invention in that the first crane boom, the second crane boom and the transport receptacle are each arranged on a chassis, which are articulated to each other.
    In this way, a double-arm crane is created in the form of an articulated train, which occupy a large length and thus can transport long loads such as pre-assembled turnout or crossing pieces. At the same time, the railway crane forms a single longitudinally rigid coupled unit that can be moved in one piece, ensuring constant distances between the crane jibs while driving. This minimizes the introduction of shear forces into the jib boom hoists during transport. Over long distances, the load can also be parked on the transport receiver. Both allow a safe and fast transport and installation operation. The railway crane of the invention is thus particularly suitable for the laying of pre-assembled points pieces, which are usually from a more distant storage or assembly station to Ver ..% 3, .- ·. ···· # ♦ «·· · ·» * * * · ♦♦ · * ·; * · «··· · * ·· ·· ♦ · · ♦ φφ · * · *« ·· * »· ♦ * · delivery a high transport speed minimizes the occupancy time of the transport track and thus interruptions of the regular train traffic on the track.
    According to a preferred embodiment of the invention, the chassis are connected by spacer rods which engage at their ends in each case articulated to a chassis. As a result, the distance between the two crane jibs can be further increased in order to transport and relocate even longer loads, which is particularly favorable when laying pre-assembled switch pieces.
    Preferably, the chassis of the transport receptacle wagon length, whereby standardized transport wagons with open loading area (so-called. "Salmon Wagons") can be used as transport recording.
    It is particularly favorable if the two crane jibs together a traverse with holding devices for a track yoke, turnout piece, crossing piece or the like. wear, and in particular when the holding means have hydraulically operated gripper. Such a traverse may e.g. as described in the patent AT 505.402 and allows a quick and safe mounting, moving and laying a track yoke or pre-assembled point or crossing piece.
    According to a particularly preferred embodiment of the invention, at least one of the crane jibs engages the traverse via a transversely displaceable adjusting slide, which is preferably hydraulically actuated. As a result, slight adjustment movements of the load can be carried out immediately when settling at the laying site, without having to operate the entire crane boom synchronized.
    It is particularly advantageous if each adjusting slide is equipped with a tilt sensor. With such tilt sensors corresponding displays for the operator or operators of the crane boom can be controlled or even the automatic synchronization of the crane boom movements are regulated in order to avoid the occurrence of dangerous tilting moments in the operation of the two crane boom.
    According to a further preferred embodiment, each crane boom has at its end a rotatable and pivotable head. Even so, further adjustment movements can be made without the need for movement of the entire crane boom.
    The adjusting carriages can be suspended from the heads via chain links in order to be able to achieve greater flexibility if the lifting height allows this because of the overhead line; But to prevent any tendency to vibrate, the chain links can also be omitted.
    The invention will be explained in more detail with reference to an embodiment shown in the accompanying drawings. In the drawings shows:
    Fig. 1 shows a railway crane according to the invention in a side view;
    FIG. 2 shows the railway crane of FIG. 1 in a plan view; FIG. and
    Fig. 3 one of the lifting harnesses of the railway crane of Fig. 1 in an enlarged side view.
    In Figs. 1 and 2, a railway crane 1 is shown, which is movable on a track 2 and is intended for transporting and levying a load 3. The load 3 is, for example, a track yoke, pre-assembled turnout piece, crossing piece, bridge piece, etc. In the case shown, the load 3 is a turnout piece, which in a manner known per se consists of rails 4, which are pre-mounted on sleepers 5 and are e.g. are equipped with appropriate actuation and control means (not shown) for the switch heart. Turnouts of this type can reach a length of 20-30 m and a weight of 20-30 t and more.
    The crane 1 is of the double-boom or double-arm type and comprises a first crane boom 7 and a second crane boom 8, between which a transport receptacle 9 is arranged. The crane jibs 7, 8 are telescoping, about horizontal axes 10 pivotally mounted and about vertical axes 11 rotatably mounted on a chassis 12, 13.
    The chassis 12, 13 may be self-propelled, for example, equipped with a drive 14 which can be controlled by a cab 15 from. Alternatively, the chassis 12, 13 could also be unpowered and the railway crane 1 e.g. with the help of a separate tractor (not shown) are moved.
    The transport receptacle 9 is arranged on a separate chassis 16, which can be equipped with or without drive. The chassis 12, 13, 16 are articulated either via conventional coupling devices 17 directly or with the interposition of spacer rods (tension and compression struts) 18 in the manner of a train hinged together. The railway crane 1 can therefore, despite its considerable length of e.g. 30 - 50 m usual track curvature radii follow articulated. In addition, the chassis 12, 13, 16 may each have a plurality of sets of wheels ("bogies") 19 rotatably mounted about vertical axes in a conventional manner to follow the radii of curvature.
    The two crane jibs 7, 8 with their chassis 12, 13 can also be installed as prefabricated units in the form of single-arm cranes in the railway crane 1. Examples of such prefabricated units are single-arm railway cranes of the brand Multitasker 250 Kirow in Leipzig. For the transport receptacle 9 with its chassis 16, prefabricated transport wagons, e.g. so-called "Salmon Wagons", are used, which have the length of conventional railroad cars.
    The spacer bars 18 are for loads in the ferry mode according to the weights of the crane boom 7, 8 i # · · ♦ 7
    and chassis 12, 13 on the one hand and the transport receptacle 9 with chassis 16 and load 3 on the other hand, and taking into account track gradients in the range of 1:30 to 1:75 designed. For example, the weight of each crane jib 7, 8 with its chassis 12, 13 about 100 t, the trans port recording 9 with its chassis 16 about 25 t, and the load about 30 - 40 t, which is a static theoretical load Distance holding rods 18 in the range of about 5 t in the direction of travel and a design - with safety margin - for about 8 t in the direction of travel results.
    Fig. 3 shows the design of the ends of the crane boom 7 and their lifting harnesses for the load 3 in detail. Each crane boom 7, 8 carries at its end a rotatable and pivotable head 20, from which via chain links 21, e.g. Hook, shackles and eyelets, an adjustment slide 22 is suspended. The Justierschlitten 22 of the two crane boom 7, 8 engage a common cross member 23, which in turn is equipped with means 24, 25 for gripping the load 3. The devices 24, 25 may be, for example, a plurality of cross bars 24 with - also hydraulically actuated - grippers 25, clamps, pliers, retaining strips, etc., to a track yoke or pre-assembled point or crossing piece together with its tracks 4 and sleepers 5 throughout its To support the length. An example of such a laying traverse 23 is described in the AT 505,402 of the same Applicant.
    The Justierschlitten 22 allow a slight horizontal reciprocation of the crossbar 23 relative to the crane jibs 7, 8 and their heads 20. The Justierschlitten 22 may include hydraulic cylinders, one part of which is suspended from the heads 20 and the other, relativeverschieblicher Part of the traverse 23 carries.
    The Justierschlitten 22 are preferably equipped with built-tilt sensors 26 which measure the inclination of the traverse 23, for example by means of a pendulum. The inclination sensors 26 may alternatively be arranged in the region of the chain connection 21, e.g. installed in two shackles so that they can detect tilt angles in all three spatial directions. The inclination sensors 26 can control a display device for the operator (s) or also directly control the drives of the crane jibs 7, 8 for their telescopic, pivoting and rotary movement in order to achieve as horizontal a position as possible of the traverse 23.
    It is understood that when swinging the crane boom 7, 8 from the transport position on the transport receptacle 9 in the position shown in Fig. 2 side of the track 2 for receiving and depositing the load 3, the crane boom 7, 8 extend telescopically according to the initiation of transverse forces in the lifting harnesses 20-22 of the traverse 23 to avoid, and retract when retracting telescoping accordingly. The controls of the two crane jibs 7, 8 can also be electronically coupled and preferably controlled by the sensors 26 accordingly. A single control system can thus take full control of the entire railway crane 1 and all its movements.
    The invention is not limited to the illustrated embodiments, but includes all variants and modifications which fall within the scope of the appended claims.
