Abstract

A mobile apparatus for loading, transporting and laying an assembled track section comprises a track section carrier comprising an elongated carrier frame, track section gripping and holding devices mounted on the elongated carrier frame, and two pairs of transversely opposite lifting jacks arranged on the carrier frame for lifting and lowering the carrier frame, the jacks of each pair being fixedly connected to each other and the pairs of jacks being widely spaced from each other in a longitudinal direction to provide a high stability during lifting and lowering of the carrier frame. A self-propelled auxiliary vehicle is movable independently of the track section carrier and comprises a flatbed frame having two opposite ends and capable of receiving and supporting the carrier with the assembled track section gripped and held thereon, and a track-bound undercarriage and an off-track undercarriage at each end of the flatbed frame.

Description

The invention relates to a mobile system for receiving or laying and transporting track yokes formed from rails and sleepers, consisting of at least one track yoke carrying device with rail gripping or holding means provided on its support frame for lifting or storing the track yoke In the longitudinal direction of the track, one after the other, pairs of lifting rams arranged opposite one another transversely to the longitudinal direction of the track, which are height-adjustable relative to the track body and can be placed thereon via a drive.

According to EP-A 0 196 701, a mobile installation for receiving or laying and transporting track yokes formed from rails and sleepers is known. This system consists of three mutually independent and spaced-apart track yoke support devices, each with two pairs of lifting rams arranged opposite one another transversely to the longitudinal direction of the track, which are height-adjustable relative to the track body and can be placed thereon using a drive. The lifting rams, which are each provided on one long side of the carrying device and arranged directly next to one another at a very short distance, are connected to one another by struts to form a rigid unit and are each attached to a transverse displacement ram. These are mounted on a carrier frame that can be moved on the track by means of a flange wheel undercarriage, with two hook-shaped rail gripping or. Holding agents stored. In this known system, three such track yoke support devices are placed at a distance from one another with the bogies on the track yoke which is placed and installed laterally next to the conversion gap. The lifting rams are then moved to their outermost lateral position facing the conversion gap with the help of the transverse shifting rams and lowered to the floor. The track yoke gripped by the gripping or holding means is raised and moved in the opposite direction together with the support frame in the outermost end position in the direction of the conversion gap by actuation of the transverse displacement stamp. This step-by-step activity repeats itself until the Gleisjoch comes to rest over the gap. These known Eeinzel-Gleisjoch support devices are quite unstable due to these lifting ram arrangements, each with a pair of lifting rams arranged at a short distance from one another in the longitudinal direction of the track, so that there is a great risk of tipping, particularly in the case of uneven or soft ground conditions. Furthermore, handling is relatively cumbersome and complex and therefore uneconomical. In addition, the Gleisjoch must be placed directly to the side of the gap.

Another known system - according to DE-OS 24 32 326 - consists of a number of track yoke support devices arranged one behind the other in the longitudinal direction of the track and of a large number of transport machines in the manner of a bogie. In this system, the track yoke, which is divided into short individual pieces, is placed on these transport machines, which are connected to one another by coupling rods, together with the same number of track yoke supporting devices, which are also connected to one another by coupling rods, and is moved by means of a tractor onto an auxiliary track in the conversion gap. The individual parts of the Gleisjoch are then lifted by the carrying devices and the transport machines and the auxiliary track are removed. Since the individual track yoke support devices each have only a single pair of lifting rams arranged opposite one another, there is no very great stability. By means of these coupling rods connecting the individual supporting devices to one another, this stability is further reduced overall and a very unstable system is created. The coupling rods only serve to at least distance the plurality of track yoke support devices from one another or to remove them together from the laid track yoke. Due to the necessary laying or dismantling of the required auxiliary track, additional time and effort is required. The handling is also relatively cumbersome and complex, as well as poor performance.

It is also known - according to DE-OS 3511 520 by the same applicant or patent owner - a system in which each track yoke support device has a support frame formed from two elongate support members which can be displaced in the longitudinal direction. Each of these two supporting parts is connected to two pairs of jacks spaced far apart from each other, so that these four pairs of jacks allow this track yoke carrying device and the raised track yoke to also move automatically in the longitudinal and transverse directions, but the total length of such a system is practically doubled.

Finally, according to EP-A 0 162 750, a system is known in which each Gleisjoch carrying device has only a single pair of lifting stamps. To transport a track yoke, several such independent and independent track yoke support devices are required. For the transportation of the track yoke together with the supporting devices to the conversion gap, several interconnected auxiliary wagons with a plateau-shaped loading area are provided, each of which has height-adjustable and rail-independent undercarriages and rail undercarriages. Such a known system is particularly unsuitable for transporting very heavy and asymmetrical switch sections, since the stability of the individual track yoke support devices is very low due to the respective two-point support.

The object of the invention is based on EP-A 0 196 701 and now consists in the creation of a mobile installation of the type set forth above, with which even the heaviest turnout track yokes with a structurally simple structure are avoided with high performance in a more precise and stable manner while avoiding auxiliary tracks Location are transportable.

The object of the invention is achieved with the mobile system described in the introduction in that the two pairs of jacks firmly connected to one another on a support frame of the track yoke support device, which is elongated in the longitudinal direction of the track, for a high positional stability in the longitudinal direction of the track at a distance of at least two Meters are arranged at a distance from each other, each lifting ram being designed to be cross-adjustable independently of the other, and that an auxiliary wagon, which can be moved independently of the Gleisjoch carrying device, is provided with a plateau loading area for supporting the Gleisjoch together with the Gleisjoch carrying device, the auxiliary wagon at the end has a rail-bound and a rail-unbound chassis.

A system designed according to the invention is relatively simple in construction and relatively safe to use and, in particular, is not too short in terms of its overall length - since stability would otherwise suffer or be too long so as not to make handling more difficult. With such a system composed of a track yoke carrying device and an auxiliary vehicle, even the heaviest, e.g. Switch track yokes provided with concrete sleepers, can be transported directly to the conversion gap in a safe location, avoiding time-consuming and labor-intensive preparation work. The elongated design of the support frame and the possible spaced apart arrangement of the lifting ram pairs, in particular designed as hydraulic cylinder-piston arrangements, ensure that the track yoke carrying device has a particularly high stability.

This is of great advantage insofar as with this spacious four-point support of the carrying device according to the invention - due to its asymmetry, it has an eccentric center of gravity and is therefore very difficult to handle - switch track yokes can be raised and lowered without any problems. In addition, the elongated support frame design enables an advantageous multiple suspension of the track yoke which is gentle on the rail fastenings. The end arrangement of two different trolleys at each longitudinal end of the auxiliary car ensures a significant increase in the performance of the system according to the invention, since the track yoke can be transported directly into the gap without auxiliary tracks.

A particularly preferred embodiment of the invention consists in that each pair of lifting stamps is arranged approximately in the central region of a respective carrier-frame longitudinal half, each lifting stamp being connected to its own, preferably hydraulically actuatable, transverse displacement stamp and being independently cross-adjustable. In this way, on the one hand - due to the large spacing of the lifting ram pairs in the longitudinal direction of the track - a high level of stability of the track yoke carrying device and on the other hand - due to the independent transverse adjustment - an advantageous adaptation to the irregular outlines of a switch track yoke can already be achieved. In particular, the individual lifting rams can also be moved or arranged independently of one another in the edge region of the track yoke in order to further increase the stability.

According to a further embodiment of the invention, the support frame and / or the track yoke support device is designed for the transport of track yokes of different lengths, the length of the support frame in the longitudinal direction of the track being at least about 3 m or the distance of five normal threshold divisions not less than 6o cm each and is at most about 15 m or does not exceed the distance of 25 threshold divisions of 6o cm each. With such a minimum length of the support frame of the track yoke support device, its high stability, in particular in connection with short or smaller track yokes, is essentially not yet impaired. On the other hand, the maximum length limit that can be achieved prevents the carrier frame from being too heavy and / or from having too little torsional rigidity.

According to a further advantageous embodiment of the invention, on the Gleisjoch carrying device there are both rail-gripping or holding means between the two pairs of lifting rams, which can be spaced apart at a distance of at least two meters, preferably hydraulically, as well as at each longitudinal end of the carrier frame arranged, which are each independently adjustable transversely to the longitudinal direction of the wagon. This triple arrangement of these very easy-to-adjust rail gripping or holding means makes it possible to suspend the rail yoke in a manner that protects the rail fastenings and avoids harmful deflection while evenly loading the carrier frame. The stability of the support device is also improved since a rotationally fixed connection between the support frame and the track yoke is now ensured.

A preferred feature of the invention also consists in the fact that the rail gripping or holding means designed as rail head tongs are displaceably mounted on guide rails which run transversely to the longitudinal direction of the wagon and which fasten a central part arranged symmetrically to the support frame and one end piece on the central part and Have side part pivotable about a vertical axis. Such an arrangement or design of the rail gripping or holding means is particularly simple and robust and can withstand even heavy loads without problems. In addition, the three-part design of the guide rail enables precise adaptation to the different widths of an asymmetrical track yoke. By simply swiveling the side parts in the direction of the carrier frame, transfer runs can be carried out without exceeding the clearance profile. The use of rail head pliers ensures safe rail detection on both sides.

A further particularly preferred embodiment variant of the invention is characterized in that the central part of the guide rail for height adjustment is connected to the support frame of the track yoke supporting device via hydraulically actuatable adjusting drives, and that a particularly cuboid-shaped guide body is fastened to the central part, which in one of the Guide body corresponding recess of the support frame is arranged, wherein the central part is rotatable relative to the guide body about a vertical axis. Due to the height-adjustable design of the guide rails, the track yoke can advantageously be raised or lowered even without actuating the lifting rams. This makes it easier to center the track yoke to the conversion gap. In addition to the lifting rams, the lifting height is increased so that the lifting rams can be arranged entirely within the clearance profile. With the guide body, the large forces occurring during the track yoke transport or laying process are transferred to the support frame.

According to further features of the invention, a number of locking pins are provided on the upper side of the guide rail for fixing a support yoke which is connected on both longitudinal sides of the guide rail with a pincer-shaped gripping or holding means and can be displaced along the guide rail. With such locking pins, a rapid displacement of the support yoke together with the rail head pliers is possible without impairing safety. It is of particular advantage that manipulation with moving parts, such as e.g. Plug pin or the like, is eliminated.

According to a particularly advantageous feature of the invention, the two rail-bound undercarriages, which are preferably designed as bogies with flanged wheel undercarriages, are each arranged at the longitudinal ends of the auxiliary vehicle, and the two track-independent undercarriages equipped with a crawler undercarriage and designed as crawler undercarriages are connected directly via a swivel frame connected to a swivel drive then articulated to the respective flanged wheel chassis on the plateau frame. Due to the arrangement of the bogie undercarriage projecting over the crawler tracks, a quick and easy rerailing can be carried out when the system is transported back from the gap. The attachment of the crawler chassis to a swivel frame enables the high loading forces to be safely transmitted to the ballast bed at any height.

In a particularly advantageous manner, the swivel frame of the caterpillar undercarriage, which is articulated to the auxiliary carriage, can be swiveled up into a corresponding recess in the plateau frame and can be connected to it by a locking device. This recess in the plateau frame enables a space-saving rest position of the crawler chassis directly under the plateau frame. Thus, the crawler undercarriage does not have a disruptive influence on the track operation while avoiding the auxiliary carriage being too high.

According to a further advantageous embodiment of the invention, it is provided that the plateau frame of the auxiliary vehicle is designed to be displaceable transversely to the longitudinal direction of the wagon wheel undercarriage wheel undercarriage, the wheel flange undercarriage being mounted in a guide running transversely to the longitudinal direction of the wagon and articulated to the platform frame Cross adjustment drive is connected. With this design of the plateau frame, a rapid and accurate transverse displacement of the track yoke can be carried out while avoiding complex additional devices which may influence safety. In this way, in the case of track joch sections projecting far beyond the side end of the wagon, obstacles located next to the track, e.g. Catenary masts or the like can be easily avoided.

Finally, according to a further feature of the invention, in particular for track switch yokes, track switch components or the like. For the joint transportation of long switch track yokes, two such track yoke support devices provided with an elongated support frame and two auxiliary carriages are arranged one behind the other. With such a combination of two systems according to the invention, particularly long and heavy turnout track yokes can also be transported quickly and safely into and from the conversion gap. A more precise adjustment can be made to the track yoke than to transport particularly heavy switch track yokes, e.g. with concrete sleepers, three or four such systems can be used together. On the other hand, however, the systems are also available individually and without restrictions for handling shorter track yokes.

The invention will now be described with reference to a preferred embodiment shown in the drawing.

A system 1 shown in FIGS. 1 and 2 for receiving or laying and transporting track yokes 4 formed from rails 2 and sleepers 3 essentially consists of a track yoke carrying device 5 and an auxiliary carriage 6. On a support frame 7 elongated in the longitudinal direction of the track Two longitudinal beams 8 of the track yoke support device 5 are arranged at each end of the frame in the transverse direction opposite one another, each forming a pair of jacks 9 and 1 jacks 11. Each pair of jacks 9,1 ₀ o is arranged approximately in the central area of one support frame longitudinal half each - for an arrangement that is spaced far apart in the longitudinal direction of the track for high positional stability, each jack 11 having its own hydraulically actuated cross-slide die 12 ( Fig.2) is connected and formed independently of each other cross-adjustable. Between the two pairs of lifting pistons 10, 11 spaced at a distance of at least two meters from one another and at each longitudinal end of the support frame 7, rail-gripping or holding means 13 connected to the latter are arranged, each independently of one another transversely to the longitudinal direction of the carrier wagon are adjustable. The transverse adjustment of the rail gripping or. Holding means 13 is carried out on guide rails 14 running transversely to the longitudinal direction of the carrier car. These consist of a central part 15 arranged symmetrically to the support frame 7 and in each case a side part 16 fastened at the end to the central part 15 and pivotable about a vertical axis. The central part 15 of each guide rail 14 is for height adjustment via hydraulically actuated adjustment drives 17 connected to the support frame 7 of the Gleisjoch support device 5. Between the two adjustment drives 17, each middle part 15 of the guide rail 14 is connected to a cuboid guide body 18. An energy center 19 which supplies the various drives of the track support device 5 is provided between the two pairs of lifting rams 9, 1. The various drives, in particular the lifting rams 11 and the adjusting drives 17, can also be remotely controlled via a remote control device 20. The carrier frame 7 and / or the track yoke support device 5 is designed for the transport of track yokes which are each different in length. The length of the support frame 7 in the longitudinal direction of the track is at least about 3 m or the distance from 5 normal threshold divisions of 6 ₀ cm each. The maximum length of the support frame 7 is about 15 m or the distance of about 25 threshold divisions of 6o cm each.

The auxiliary carriage 6, which can be moved independently of the Gleisjoch carrying device 5, is designed with a plateau loading area 21 for supporting the Gleisjoches 4 together with the Gleisjoch carrying device 5. At each end, the auxiliary carriage 6 has both a rail-bound and a rail-independent running gear 22 or 23. Each rail-bound undercarriage 22 is designed as a bogie with flanged wheel undercarriages 24 and a drive 25. The two non-rail-mounted undercarriages 23, which are equipped with a travel drive 26 and are designed as crawler undercarriages 27, are articulated directly to the respective flanged wheel undercarriage 24 on the plateau frame 29 via a swivel frame 28. Between swivel frame 28 and the plateau frame 29, a swivel drive 3o is provided for height adjustment of the crawler chassis 27. The swivel frame 28 can be swiveled up into a corresponding recess 31 of the piateau frame 29 and can be connected to it by a locking device 32.

It can be seen in particular from FIG. 2 that the plateau frame 29 of the auxiliary car 6 is designed to be displaceable transversely to the longitudinal direction of the car relative to the flange wheel undercarriage 24. For this purpose, the rail-bound undercarriage is mounted in a guide 33 of the plateau frame 29 running transversely to the longitudinal direction of the wagon and connected to a transverse adjustment drive 34 articulated thereon. For the joint transport of long switch track yokes 4, two such track yoke support devices 5, provided with an elongated support frame 7, and two auxiliary carriages 6 are arranged one behind the other. Approximately centrally on the underside of the plateau-frame 29 an energy is _"giezentrale 35 is provided to supply the actuators located on the auxiliary carriage. 6 at one end of the auxiliary carriage 6 a height-adjustable via a drive 36 forklift is arranged 37th This by the inventive system 1 The switch rail yoke 4 that is transported is shown in FIG. 2 for the better overview, for the most part, only in the outlines with dash-dotted lines.

As can be seen in FIG. 3, each transverse displacement stamp 12 is designed as a preferably square-shaped guide tube 38 which is connected to the carrier frame 7 and in which a telescopic outer tube 39 is slidably mounted by means of a drive 40. The end of the telescopic outer tube 39 is connected to a correspondingly square-shaped guide tube 41 of the lifting ram 11. A likewise square-shaped telescopic outer tube 42 is mounted in this and can be displaced in the vertical direction with the aid of a drive 43 attached to the end of the guide tube 41. At the free ends of the telescopic outer tubes 42 of the lifting rams 11, a support plate 44 is provided for resting on a ballast bed 45. The rail gripping or holding means 13 are arranged in pairs for gripping a rail 2 of the track yoke 4 on the guide rail 14 and can be displaced in the longitudinal direction thereof. On the top of each guide rail 14, a number of locking pins 46 are provided for fixing a support yoke 47 connected to a pliers-shaped gripping or holding means 13 on both longitudinal sides of the guide rail. The rail-bound undercarriage 22 designed as a bogie is supported on both sides by supports 48 on the underside of the plateau frame 29. A guide pin 49 is provided in the center, which is guided in the transverse guide 33 and is connected to the transverse adjustment drive 34. Since its piston rod is connected to the plateau frame 29, when the transverse adjustment drive 34 is actuated, the plateau frame 29 is displaced transversely relative to the rail-bound undercarriage 22, with the supports 48 ensuring reliable support of the plateau frame.

In the greatly enlarged cross section through the guide body 18 according to FIG. 4, it can be seen that the guide rail 14 can be rotated relative to the guide body 18 about a vertical axis 50. For this purpose, the middle part 15 of the guide rail 14 is connected to a circular turntable 51, which in turn is enclosed at the end by a turntable counterpart 52 connected to the guide body 18. With this counterpart 52 and the guide body 18, a cross member 53 is connected to which the piston rods of the adjustment drives 17 are articulated. These are connected in the opposite end region to brackets 54 fastened to the carrier frame 7. The guide body 18 is mounted in a recess 55 extending between the longitudinal members 8 of the plateau frame 7 so as to be vertically displaceable, forming a gap 56. Reinforcements are provided in the inner corner regions of the guide body 18. The highest position of the guide body 18 and the guide rail 14 that can be reached after actuation of the adjustment drives 17 is shown with dash-dotted lines. A cover plate 57 is arranged on both longitudinal beams 8 of the plateau frame 7.

In the plan view according to FIG. 5, the recess 55 for guiding the height of the guide body 18, formed by the lateral limitation of the side members 8 and the cross members 58 connecting them to one another, is clearly recognizable. The longitudinal members 8 are also connected to one another in both longitudinal end regions by cross members.

6 shows the rail gripping or holding means 13 which can be displaced along the guide rail 14 which is preferably formed in the T-profile and which are designed as rail head pliers 59. This consists of two pliers parts held by a spring under tension, which are connected at the end to the support yoke 47 via a short chain. Handles 6o are also provided at the end, with which the two tong parts can be moved apart against the resistance of the spring in order to guide the rail head pliers 59 over the rail head. The middle part 15 and side part 16 of the guide rail 14 are connected to one another by a joint 61, as a result of which the side part 16 can be adjusted in a horizontal plane relative to the middle part 15. To lock the side part in the desired position relative to the middle part 15, a bolt 62 can be inserted in the upper horizontal leg of the guide rail which is T-shaped in cross section.

As can be seen in FIG. 7, the support yoke 47 comprises the upper horizontal leg of the guide rail 14 in such a way that the support yoke can be adjusted in height by the height of the locking pins 46. In this way, the support yoke 47 together with the rail head pliers 59 can be moved into the desired position transversely to the guide rail 14. As soon as the correct position is reached, the support yoke 47 is placed on the guide rail 14 between the adjacent locking pins 46.

In the following, a preferred possible method of working with the mobile installation 1 according to the invention for the dismantling of, for example, an approximately 30 m long switch track yoke will be described with reference to FIGS. 1 to 3.

The system 1, composed of two track yoke support devices 5 and two auxiliary carriages 6 for such long track yokes, is moved to the track yoke 4 to be removed by means of the rail-bound undercarriages 22. The Gleisjoch carrying device 5 rests with its lifting plungers 11 on the loading surface 21 of the auxiliary car 6 and is braced with it by means of ropes 63 shown in broken lines. As soon as the system 1 is located exactly above the track yoke 4 to be dismantled, the ropes 63 are removed and the support frame 7 is raised onto the loading area 21 by lowering the guide rails 14. Thereafter, the lifting rams 11 can be easily positioned laterally next to the track yoke and lowered onto the ballast bed by actuating the transverse adjustment drives 12. After the lifting rams 11 have been placed on the ballast bed, the entire Gleisjoch carrying device 5 is lifted off the auxiliary vehicle. Then both auxiliary carriages 6 are moved away from the track yoke 4 to be removed to the subsequently laid track. This is preferably done by an operator 64 standing to the side of the track, who can carry out the corresponding controls with the aid of a remote control device 65. Then the telescopic outer tubes 42 of the lifting rams 11 are retracted and the entire track yoke carrying device 5 is thus lowered onto the track yoke.

The last fine lowering for grasping the rail head by the rail head pliers 59 is carried out by actuating the adjustment drives 17. By lowering them, the guide body 18 together with the guide rail 14 is also moved to the track yoke 4. After the rail head tongs 59 have been positioned exactly over the corresponding rails of the track yoke 4 and brought into connection with the rail head, the track yoke 4 is lifted by the telescopic outer tubes 42 of the lifting rams 11 being extended again. As soon as the distance between the lower edge of the track and the ballast bed 45 is slightly larger than the height of the auxiliary car 6, this movement is stopped. The auxiliary wagons 6 are then moved onto the exposed ballast bed 45 with the aid of the lowered crawler tracks 27. For this purpose, a small auxiliary ramp is used to overcome the height difference between the track and the lower ballast bed 45 using old sleepers. Forklift truck 37 is provided to transport these sleepers. After reaching the intended position of the auxiliary car 6 just below the Track yoke support devices 5, together with the raised track yoke 4, are lowered onto the loading area 21 by the telescopic outer tubes 42 of the jacks 11 being retracted. After the lifting rams 11 have been lifted and retracted, the track yoke carrying device 5 rests on the rails 2 of the track yoke 4 via the guide rails 14 and is braced with the auxiliary carriage 6 with the aid of page 63. Thereafter, the removal can be carried out immediately in one or the other longitudinal direction of the track, in that the travel drives 26 of the crawler tracks 27 are acted upon.

After reaching the threshold ramp mentioned, the foremost rail-bound undercarriage 22 is placed on the track and the adjacent crawler undercarriage 27 is pivoted up by actuating the swivel drive 30.

This change process is repeated for all other trolleys. If the forwarding should now be carried out by a section of the turnout track yoke 4 which protrudes strongly to the side, the transport by a catenary mast or the like standing to the side of the track. be hindered, the transverse adjustment drive 34 is actuated shortly before. This actuation takes place in such a way that the plateau frame 29 together with the track yoke 4 and the track yoke carrying device 5 is moved transversely away from the said obstacle. After passing the obstacle, the plateau frame can be returned. The drives are preferably controlled by an operator located on the Gleisjoch carrying device 5. When raising or lowering the track yokes, remote control of the drives is expediently carried out with the aid of the remote control device 20.

The subsequent laying of a new switch track yoke is done in the reverse order. It is of course also possible within the scope of the invention to use three or four auxiliary carriages 6 and track-yoke support devices 5 together, in particular in the case of very long and very heavy switch track yokes 4 due to the use of concrete sleepers. Likewise, a system 1 composed of only one auxiliary car 6 and one track yoke carrying device 5 can of course also be used for shorter switch track yokes. Another advantage is the possibility of independent use of track support devices 5 and auxiliary carriages 6 according to the circumstances. For example, the Gleisjoch support devices 5 remain at the location of the conversion gap and are only used for lifting and loading the track or for unloading and lowering the track yoke. The auxiliary carriages 6 then transport the track yoke 4 without the track yoke carrying devices 5 at a longer distance to a suitable location, where the track yoke 4 can be lifted off by special cranes or else by other track yoke carrying devices 5. Subsequently, the auxiliary wagons 6 drive back loaded with a new track yoke to the ready track yoke carrying devices 5. But it is also a sole or independent use e.g. the auxiliary carriage 6 is possible by directly taking over the track yokes from special wagons and transporting them to a conversion gap where the track yokes e.g. can be lifted and laid by special cranes.

A machine as claimed in any of Claims 1 to 4, characterized in that the rail gripping and holding units (13) in the form of rail head pincers (59) are mounted for displacement on guide rails (14) which extend transversely of the longitudinal axis of the carrier waggon and which comprise a middle section (15) arranged symmetrically to the girder frame (7) and lateral sections (16) fixed at their ends to the middle section and pivotal about a vertical axis.

6. A machine as claimed in any of Claims 1 to 5, characterized in that the middle section of the guide rail (14) is connected to the girder frame (7) of the track panel carrier (5) for vertical displacement by hydraulic displacement drives (17) and in that an in particular parallelepipedic guide element (18) is fixed to the middle section (15) and is arranged in a recess (55) in the girder frame (7) corresponding to the guide element, the middle section (15) being rotatable about a vertical axis (50) in relation to the guide element (18).

7. A machine as claimed in any of Claims 1 to 6, characterized in that a number of locking pins (46) are arranged on the upper side of the guide rail (14) to fix a carrying panel (47) connected on either side of the guide rail to a pincer-like gripping and holding unit (13) and designed for displacement along the guide rail.

8. A machine as claimed in any of Claims 1 to 7, characterized in that the two on-track undercarriages (22) which are preferably in the form of bogies with flanged wheels (24) are arranged at either end of the auxiliary waggon (6) while the two off-track undercarriages in the form of crawlers (27) equipped with an axle drive (26) are pivotally connected to the platform frame (29) immediately adjoining the flanged wheel undercarriage through a pivotal frame (28) connected to a pivoting drive (30).

9. A machine as claimed in Claim 8, characterized in that the pivotal frame (28) of the crawler undercarriage (27) which is pivotally connected to the auxiliary waggon (6) is designed to be pivoted upwards into a corresponding opening (31) in the platform frame (29) and to be fastened to the platform frame by a locking mechanism (32).

10. A machine as claimed in any of Claims 1 to 9, characterized in that the platform frame (29) of the auxiliary waggon (6) is designed for displacement transversely of the longitudinal axis of the waggon relative to the flanged wheel undercarriage (24), for which purpose the flanged wheel undercarriage (24) is mounted in a guide (33) extending transversely of the longitudinal axis of the waggon and is connected to a transverse displacement drive (34) pivotally connected to the platform frame (29).

11. A machine as claimed in any of Claims 1 to 10, more especially for switch panels, switch components or the like, characterized in that two track panel carriers (5) provided with an elongate girder frame (7) and two auxiliary waggons (6) are arranged one behind the other for the common transport of long switch panels.
