t Track construction machine for laying and removing assembled track sections or track connections

The invention relates to a track construction machine for laying and removing assembled track sections or track connections with a supporting structure extending in the direction of the track, which is connected to in Direction transverse to the track movable and adjustable lifting devices is equipped and in one Distance that is greater than the length of a mounted track section or a mounted track connection has two end vehicles, one of which has a motorized bogie and at least one motorized caterpillar that can be used as an alternative to the bogie and the other with at least is equipped with a bogie, and with means provided on the supporting structure for gripping one mounted and placed on the ground next to the track Track section or a track connection.

The laying and dismantling of installed track sections and track connections, such as Crossings, and junctions, are becoming almost general today the earlier practice of assembling and disassembling

preferred on the spot, for the main purpose, the 25

To disrupt rail traffic only for the shortest possible time.

The complex structure of track connections and their 'considerable length mean that the assembly and the Dismantling the. they form elements such as straight and curved rails, switch blades and switch frogs and guardrails on the sleepers themselves at the place of their use are not compatible with the train sequences of rail traffic, because of the duration of these operations.

T The installation of a new track connection that goes with it

If it is intended to replace an old one, this is done • at a selected, sufficiently free location as close as possible to the substitution point, next to it or even on a second track that is there and which is used for the transport of this new, pre-assembled track connection.

The old, to be replaced track connection is for the same reason, namely to protect rail traffic, also assembled expanded and over. removed the track.

Before laying the new track connection in place of the old one, the ballast is treated and in particular leveled by so-called planning work, carried out by other machines suitable for this work are executed.

There are machines of the type described above are known, which were developed for expanding at the same time and the removal of a track section or an old track connection, and the laying of a new one Track section or a new track connection. These machines are capable of turning at the same time to move on the track and on the ballast, as well as to set up such track sections or connections.

take, move sideways and carry.

In a machine of this type, which is described in DE-OS 23 13 055, the support structure at their ends. vertical axes pivoted on two vehicles, each of which has two for Travel on suitable axles and equipped with two caterpillars suitable for travel on the ballast which can be used alternatively. In this machine, the supporting structure has a lifting device,

which is formed from an extendable hoist arm, 35

which can be rotated by 360 * in a horizontal plane, is mounted on "a trolley that can be moved along this supporting structure". Furthermore, the machine has means which enable a section or a track connection to be gripped on the ground next to the track and which is assigned by each vehicle side retractable supports are formed, which are designed to ensure the lateral stability of the machine during the lifting of these loads.

In another known machine, described in DE-PS 29 28 152, the support structure is not articulated, but simply fixed at their ends to two vehicles, having restriction means, the mixed locomotion * ⁵ which is formed from caterpillars and bogies are, which are arranged rotatably about vertical axes relative to the chassis of these vehicles. In this machine, the glue means are made up of hoists which can be moved in a known manner and are adjustable transversely to the track, and the means that allow the gripping of a mounted track section or a track connection placed on the ground next to the track are through their own caterpillars formed leading to this

Purpose arranged pivotable by 90 ° about a vertical axis are to move the whole machine sideways up over this section or this To enable track connection.

These known machines have the great advantage .30

that only a single track is used and occupied during the laying and upgrading work which itself contains the track section to be replaced or the track connection. This is made possible by the fact that these machines

34192A0

Ϊ are suitable for spanning the length of the work zone and grab a section or a track connection between your two end vehicles, pick up or put down and drive with these loads on the same track.

However, the length of the support structure of this machine between its end vehicles is necessary limited by the obligation to use this construction in the curves of the track within the valid sideways Keep safety vehicle gauge.

In the curves, the middle area of the supporting structure is offset by a value to the inside of the curve, that of the filing height of the by the curvature of the longitudinal axis of the track between the joints of the end bearings of the machine corresponds to the arc described. During the process over long distances, this offset must not have the consequence that the supporting structure Exceeds the prescribed “vehicle gauge” to avoid any risk of hitting

lateral obstacles that are outside these limits be able to avoid, in particular, obstacles caused by one on an adjacent one Tracked train are formed.

This is a disadvantage for such machines because.

they can therefore use certain track connections of the large high-speed rail lines that are now being developed do not remove and install in a single assembled length. As an example of such Track connections are the branches that extend over lengths of more than 60 m can, because of their small radius of curvature, necessarily due to the high driving speeds the trains is limited. That is twice the length of the track connections laid with these machines

or can be expanded.

A completely different type of railway installation is also known, which is used for laying and expanding such Long track connections are suitable and which is described in FR-PS 1 540 039. but this installation is complex compared to the machines described above and requires a considerable amount Additional work steps without direct reference to the work steps of the actual laying and

10. of expansion. This device comprises a multiplicity of movable elements, such as gantry cranes, trolleys, and lifting devices which are arranged displaceably along a hinge beam. These elements have to be brought into position, moved and removed one after the other according to the progress of the work, while the supporting beam itself is held in a rigid position above the work zone. The track connection to be laid or expanded is transported on the track in some other way, regardless of the articulated support, in _{front of} or behind the same, and on chassis. The transport of the track connections on the chassis to the supporting beam or vice versa takes place through the portals. Also, this facility doesn't give the. Possibility of grabbing a track connection with your own means and transporting it under the supporting beam, which has been previously assembled and placed next to the track on which the machine is running.

The object of the invention is to create the possibility of increasing the range of machines in the introduction to the description at least doubled so that they can be used for installation and removal of track connections of great length, while maintaining their. Advantages over the foregoing facility described, its simplicity of

3419240 -ιοί application as well as the construction and its Ability to grasp or lay down a track connection next to the track to be treated with one's own means.

To this end, the machine according to the invention is characterized in that its supporting structure consists of at least two parts that are connected to each other by a universal joint that the supporting structure is provided with an intermediate support which is arranged in the area of the universal joint and on the one hand has an intermediate vehicle with two side caterpillars, which are individually driven and both Individually adjustable and adjustable in height and across the track on a frame are hinged to one of the two parts of the support structure so as to be rotatable about a vertical axis, and which, on the other hand, has an intermediate bogie that can be temporarily left on the track and which is articulated rotatably about a vertical axis by means of a pivot bearing under a carrier, which with one of the two parts of the supporting structure is connected by a suspension device, with at least a post which can be passed through the track connection and which has a releasable

"re connection with the one carrying the intermediate bogie Has carrier.

This allows the combination of effects resulting from the design of the supporting structure and the intermediate support result in a simple

■ ^{1) (i} and, surprisingly, the laying and dismantling of assembled track connections with a length that is more than twice the length of the track connections, which are laid and extended with the known machines of the type described in the introduction to the description.

can be built while maintaining their advantages.

Thanks to its design, the intermediate support enables the supporting structure to be supported in its area by their caterpillars on both sides of the track and by leaving the bogie standing, either on one of the two end vehicles or outside one of the end vehicles after this has driven over the bogie like a bridge.

As a result, a track section can be gripped, laid or expanded between the two end vehicles or a track connection with a length that corresponds to the total range of the supporting structure can correspond. The track section or the track connection is lifted using the lifting devices, after simply placing the two in front of and behind the vertical below the post of the suspension device of the intermediate bogie, the sleepers located have been loosened and slightly removed from each other to allow the Allow passage of the post. In addition, the range of the supporting structure can be doubled here exceed the range of the known machines, thanks to the training of this support structure in at least two mutually hinged parts, the length of each part being the length of the known Machines can correspond without the safety vehicle gauge in the transverse direction in the curves Z.U exceed and without this reach the space that is occupied by the intermediate support, to lose.

In one embodiment of the invention, in which the suspension device of the intermediate bogie has two has vertical posts, these posts have a minimum distance that is below the suspension device from the rails of the track connection in transverse

direction of occupied space.

The advantages of this embodiment as well as other possibilities offered by the invention bound embodiments are apparent from the following description.

The machine shown in its entirety in FIGS. 1 and 2 is composed of a supporting structure 1, which extends in the direction of the track 2 over the same and which consists of two parts 1A and 1B, which are interconnected by a universal joint 3, and which are a number of movable and adjustable lifting devices 4 in the direction transverse to the track, two End vehicles 5 and 6 with a distance that is greater than the length of a mounted track connection 7, which is shown hanging on the lifting devices 4 in this figure, and an intermediate support 8, which is shown in FIG

near the universal joint 3, here on part 1A the supporting structure, is arranged.

The two parts 1A and 1B of the supporting structure 1 are two hollow beams with a rectangular cross-section.

The two end vehicles 5 and 6 are designed identically and have a motorized bogie 9 and two lateral caterpillars 10, which alternatively are to be used on track 2 and on the ballast.

On each of the two vehicles, the one on the left, JQ

designated by the reference numeral 5, detalliert in Figures, is shown 3 _r 4 and 5 _7, the bogie 9 and the track 10 on a chassis 1 about a vertical axis X are rotatably disposed on the corresponding portion of the support structure, with

Help a composite support 12, which a Trunnion 13 and two side support plates 14 which are supported on two corresponding support plates carried by the chassis. The bogie 9 is formed from two axles 15 which are mounted on the chassis 11 by means of two swivel supports 16 are arranged adjustable in height. The pivot supports 16 carrying the axes are about horizontal Pin 17 pivoted rotatably on the chassis. The height adjustment of each axle 15 with respect to the chassis 11 is achieved by a hydraulic piston-cylinder unit 18, and each axis 15 is through a Hydraulic motor 19 built into their swivel supports 16 is driven.

* 5 The chassis 11 is made up of two parallel vertical ones Composed end shields 20, which are connected via two upper cross members 21 on which the piston-cylinder units 18 are supported, and two lower hollow cross members 22 with a rectangular cross-section, in which

Two side arms 23, also with a rectangular cross-section, are arranged to be displaceable transversely to the track. At the outer end of each of the two side arms is a vertical hollow post 24 with a rectangular cross-section attached, in which a vertical stand 25, also

with a rectangular cross-section, is arranged displaceably.

The lower part of each stand 25 has a horizontal bearing pin 26 on which one of the two caterpillars 10 is stored.

The transverse adjustment of each side arm 23 is controlled by a hydraulic piston-cylinder unit 27 and the vertical adjustment of each stand 25 by means of a hydraulic telescopic piston-cylinder unit 28.

Each caterpillar 10 is powered by a built-in hydraulic motor 29 powered.

34192A0

This design of each of the two end vehicles 5 and makes it possible, by combining the lowering of the Axes with the lifting and approaching of the caterpillars while the machine is moving along the track With the help of their driven axles in the position according to FIG. 1 and FIG. 3, these caterpillars within the vehicle gauge to hold across the track. By the reverse operations, the lifting of the axles and the lowering and extending of the caterpillars, this arrangement also enables the track to be carried over theirs

To span the entire length also, as in the position shown in Fig. As well as Figs. 4 and 5, as well the. To keep free space below the chassis 11 of the vehicle as much as possible. "The intermediate support 8 has on the one hand a

Intermediate vehicle 30 with two lateral caterpillars 10, which are individually driven and individually adjustable and controllable both in height and across the track and which are the same as at the Endon

vehicles 5 and 6. On the other hand, the intermediate support 8 has an intermediate bogie 31 that temporarily can be left standing on the track. The intermediate vehicle 30 and the intermediate bogie 31 are independently on the same part 1A

the supporting structure is arranged, the bogie 3f being closest to the universal joint 3.

The crawler intermediate vehicle shown in FIGS and 9 is shown in a position corresponding to FIG. 2, has a frame 32 which is around a Vertical axis X rotatable on part 1A of the supporting structure is articulated, here also by means of a mixed support 33, which is a journal bearing 13 and has two lateral support plates 14, which rest on two corresponding support plates on the frame prop up.

The two caterpillars 10 are arranged on the frame 32 of the intermediate vehicle in the same way as on end vehicles 5 and 6, and the like items this arrangement are therefore designated by the same reference numerals / so that the preceding Description can be referenced. The frame is in turn connected by two Traverses 22 formed ·.

The intermediate bogie 31, which in FIGS. 6 and 7 in detail in a position corresponding to FIG is formed from two axles 34 which are carried by a rigid frame 35. The frame 35 is rotatable about a vertical axis X by means of a journal bearing 84 under a carrier 36, here in FIG Form one with the part 1A of the supporting structure through a suspension device 37 connected traverse, articulated. The suspension device 37 includes here two vertical posts 40 which are rigidly attached to the ends of an upper cross member 38 which is connected to the part 1A connected by means of an adjusting device 39 for adjusting its height position with respect to the part 1A is.

The two vertical posts 40 have a minimum distance from one another, which is below the suspension device 37 corresponds to space occupied by the rails of the track connection 7 in the transverse direction. Indeed is shown in an advantageous manner / that this space is required for the great majority of track connections of great length in the area under consideration is smaller than the width of the safety boundary line of the track, namely by a value that is necessary for the implementation of the two posts 40 on the outside of the rails within this boundary line is sufficient.

The adjusting device 39, which the upper Tr- ' 35

Verse 38 of the suspension device 37 connects to part 1A of the supporting structure, is composed of two vertical columns 41 attached to this traverse and two tubular vertical sliding guides 42, which are attached to the part 1A and in which the columns 41 are slidably arranged. The adjustment of the height position of the traverse 38 with respect to the part 1A is carried out by means of two hydraulic ones Piston-cylinder units 43, which, acting in parallel, the columns 41 in the sliding guides 42 move.

The carrier 3 carrying the intermediate bogie 31 is connected to the two posts 40 by two detachable end connections positively connected, each of which consists of a firmly connected to one of the posts 40 conical pin 81 which is inserted into a conical receiving sleeve 82 at one end of the carrier 36 is. These two elements are locked into each other by a screw 83 which is inserted into the pin 81.

and is supported on the carrier 36.

The intermediate bogie 31 is pivotably arranged here on a journal bearing 84 which is connected to a carrier 85 is firmly connected, which in the direction transverse to

Track along the carrier 36 of the suspension device 25

slidable and adjustable, with a limited adjustment path, which is determined by the need for evasive action possible lateral obstacles outside the boundary line is determined during the self-employed Trips to transport the track connections on the track in empty run. But this agility is not indispensable, and the journal bearing 84 can also be fixed be arranged on the carrier 36.

The intermediate bogie 31 can be stopped on the carrier by any means, such as

341 92A0

for example a bolt 86 for stopping the carrier 85 of the journal bearing on the carrier 36, or also by means of a piston-cylinder unit which connects this carrier with the journal bearing and which in this case Opportunity can serve as a means of adjusting the relative position of these two elements to one another.

In this embodiment the intermediate bogie is 31 can be expanded by separating it from the support 36 carrying the posts and can be left standing on the track will. Here, after loosening and removing the screws 83, the upper cross member 38 and the two posts 40, which form a one-piece part, raised by means of the adjusting device 39 for adjusting the height position until the pin 81 is above the

^ 5 carrier 36 are disengaged. The machine is there supported in this area on the caterpillars 10 of the intermediate vehicle. Before grabbing and lifting the Track connection 7, the two sleepers of this track connection, indicated by a cross in Fig. 6, which are located below the two posts 40, solved and brought to a distance that is sufficient, to allow these two posts to pass between the sleepers.

The height adjustment path and the cross adjustment path each

Crawler 10 of the end vehicles 5 and 6 and of the intermediate vehicle 30 are described in this, as an example Embodiment dimensioned sufficiently to transport the machine over long distances on coupled machines Enable platform freight cars to be pulled by a locomotive. This possibility is illustrated by FIGS. 11 and 12, in which a platform trolley 50 is shown on the track 2 is. To do this, you have to go to the machine that was previously on track 2 and go over there 35

34192A0

its three bogies was supported, first the crawlers 10 of the three vehicles moved apart, then placed on the ballast of both sides of the track and finally lowered to the two Raise parts 1A and 1B of the supporting structure and the three bogies to a height sufficient to drive platform trolleys 50 under the bogies and between the caterpillars in one position which corresponds to that shown on the right-hand side of FIG. Then the caterpillars become 10 raised and guided inwards into a position which corresponds to that on the left-hand side of FIG. Simultaneously with these operations, when the machine is supported on its caterpillars, the intermediate

^ 5 bogie 31 pulled up using the adjustment device 39 for lifting the suspension device that is carried by her 37. At this moment there are all elements of the machine within the vehicle gauge in the direction across the track, which are in denoted by G in this figure. Their supports are by suitable wedging on the platform trolley 50 determined how these supports may also be formed, by the bogies, the caterpillars or by additional loose supports, depending

according to the load distribution on these wagons.

This possibility of transporting the machine on platform freight wagons completes the independent movement under load with the help of the axles of the bogies

of the end vehicles 5 and 6 driving hydraulic motors 30

do not work, for example from the location of the installation of a track connection, generally close to the laying point, up to this installation point, as shown in FIG. 1. This: possibility of transportation the machine on wagons is advantageous because it

makes it possible to avoid the use of bogies with coupling devices, brakes and drive motors of greater power, which are necessary for the Empty journeys over longer distances are mandatory.

Each lifting device 4 arranged on the supporting structure of the machine, which is shown in detail in Fig. 13,

14 and 15, includes an immovable cross-member 51 rigidly attached to the support structure 1A-1B is, two outriggers 52 of this traverse, äine hoist trolley 53, which on this traverse and their Outriggers are movable and equipped with a motorized hoist 54, and one in the ropes of the Weaker carrier 55 suspended from the hoist with adjustable rail hooks 56.

Each arm 52 is carried by a bracket 57 which is pivotable about a vertical axis in two on one Side wall of the supporting structure 1A-1B attached bearings 65 'is mounted in such a way that it can be placed against the side wall by pivoting about this axis, as in FIG left part of Fig. 13 and in the upper part of Fig.

15 is shown. The pivoting movement is effected and controlled by means of a hydraulic piston-cylinder unit 58, which is located at one end on one at the Side wall of the support structure 1A-1B attached side arm 59 supported and with its other end on a laterally displaced pivot pin 60 which is carried by a lever attached to the bracket 57.

The pivoting movement of the boom 52 achieved by the action of the piston-cylinder unit is opened all of the lifting devices 4 located on the same side of each part 1A and 1B of the supporting structure transfer. This transmission takes place by means of coupling rods 62 visible in FIG. 15 as well as in FIGS. 1 and 2, each of which at both ends with pivot pins 60 of 35

Lever 61 of two successive arms 52 are connected. In this way, one is enough Piston-cylinder unit to all of the booms 52 located on one side of each part 1A and 1B of the supporting structure are to be pulled in or swung out at the same time.

Each boom 52 of each lifting device 4 is here with a retractable one hinged at its end lateral support 63 equipped. This lateral support consists of four different elements with kinematics inscribed in a vertical plane, namely a pivotable triangular support 64, which with a first tip 65 is articulated at the end of the boom 52, a first for pivoting the triangular support 64 specific hydraulic piston-cylinder unit 66, which is connected to a second tip 67 of the triangular support is connected, a support foot 68 and a second piston-cylinder unit 69, which this support foot on End of their piston rod and their body on the

third tip 70 of the triangular support 64 is hinged.

This lateral support 63 is, as shown in Fig. 13, inserted by pulling out the first piston-cylinder unit 66 to the end of the stroke, as well as by pulling out of the second piston-cylinder unit 69 to

Impact of the support leg 68 on the ground 71. The retraction is achieved by withdrawing the two Piston-cylinder units until the end of their stroke, as shown in FIG. 14.

This special conception of the retractable side

Chen support has the advantage of requiring a minimum of space in the retracted position with a maximum to be connected to extendibility in the operational position, both vertically and laterally. This effect will achieved thanks to the fact that their structure is connected

with its kinematics, it enables the connection point 70 of the support leg 68 during commissioning supporting piston-cylinder unit 69 simultaneously lower and move away from the support structure and conversely, to raise this point back into the retracted position and to approach the supporting structure.

In this embodiment, the lifting device, as shown in FIG. 13, enables a pre-assembled one to be gripped and on the floor 71 next to the track 2 on which the machine is running, the track connection 7 and the ™ Passing the same under the supporting structure 1A-

1B, without the machine's balance being disturbed, thanks to the lateral support 63, and in a simple and reliable manner, without the need to move the machine sideways.

However, a track connection laid next to the track can also be grasped without the aid of any kind of lateral supports, in that the independent lateral mobility of each of the caterpillars 10 of the machine is used. This is done after the machine has been placed on its caterpillars by successively adjusting each of the caterpillars sideways, while the balance is ensured by the other caterpillars until the supporting structure is vertically above the track connection. The return to track 2 in the loaded state is then carried out in the same way in the opposite direction. While this page adjustments the torsional strain of the support structure, each time a caterpillar is lifted prior to their lateral displacement, depending on which bead is added, sometimes even soon absorbed by the connection point with the universal joint 3 of the support structure. Therefore, if this type of track joint gripping is chosen, the universal joint 3 must be sufficient

designed to be resistant to this tension to be able to record.

Laying a track connection 7, which is intended is to replace an old track connection is done with the help of the machine in the following way:

The machine is in its independent transport position shown in Fig. 1 until the interruption of track 2 brought in front of the ballast bed 72, which has been leveled beforehand and which this track connection 7 should record.

The vehicle 5 closest to the ballast bed 72 is placed on caterpillars and raised, as shown in Figs. The machine is motorized in the direction of arrow A with the help of the Crawlers of this vehicle and the motorized axles of the other end vehicle 6 over the ballast bedding 72 advanced until the intermediate vehicle 30 arrives above the ballast bed 72. Here is that Intermediate bogie 31 still supported on track 2.

The caterpillars 10 of this intermediate vehicle are then moved apart and shown in FIGS Arrangement placed on the ballast, and the carrier 36, the intermediate bogie 31 supporting Suspension device 37 is supported by the posts

this suspension device separated by removing the screws 83 (Fig. 7) and lifting this carrier, until the pins 81 of the posts are pulled out of the receiving sleeves 82 of the carrier 36. After this operation the machine is advanced again in the direction of arrow A, with the bogie 31 in place and stands until the last vehicle 6 arrives at him. At this moment the vehicle becomes 6 in turn placed on his caterpillars 10, then sufficient raised so that it the intermediate bogie 31

can cross, and finally the machine is advanced again in the same direction until completely above the ballast bed 72 in the position shown in FIG. The intermediate bogie 31 is left behind the machine on track 2. The intermediate support is in this position 8 completely cleared of any obstacle. In their middle part between the caterpillars 10, as shown in Fig. 10, and the track connection 7 can be lowered and as a part of its Place to be relocated. The precision of this laying is achieved by the interaction of the caterpillars 10, of the three vehicles that allow the supporting structure to be displaced lengthways and crossways, and the lifting devices 4, the transverse movements of the track connection 7 with respect to the supporting structure enable.

As soon as the track connection 7 is laid, the machine is put on the track by the reverse maneuver brought back. The construction of a track connection is done essentially in the same way, 'so far it concerns the positioning of the machine over the old, to be expanded track connection, with the one that is close at hand Difference that the machine extends beyond the -

se track connection can be brought on its three bogies, and the lifting of the same with the help the caterpillars 10 and the removal of the intermediate bogie 31 can be done on the spot.

The advantage of this mode of operation consists in the fact that the removal of the intermediate bogie parallel tracks under the supporting structure are in no way occupied for train traffic, if they exist, what allows working in complete safety,

without obstructing the traffic on these tracks. 35

The formation of the intermediate bogie 31 carrying the suspension means 37 is advantageous, because it allows, if it is deemed necessary, the lateral displacement of this bogie with respect ^au f AEIE supporting structure without bending stresses in the structure of the hinge device to be generated by the fact that the two Ends of the carrier 36, between which the bogie can move, are supported on the two posts 40.

If a transverse adjustment of the bogie 31 is not is deemed necessary, the variant shown in FIG. 16 is a simplified and economical one Solution.

In this variant, the suspension device 37 has only a single post 400, which is rigid with connected to a part 1A of the supporting structure and from this is directed vertically downwards, and the journal bearing 84 of the intermediate bogie 31 is located fixed centrally under the support 36 perpendicularly under the post. Of course, the move the support obtained in this way on the bogie. The releasable connection between the post 400 and the bracket 36 consists of one with the post

"firmly connected conical pin 81, which is in a with the support firmly connected conical receiving sleeve 82 is used, these two elements in one another are blocked by a detachable member, which is a radial pin 87 here. In this variant after pulling out the pin 87, the bogie from the support 36 by lifting the support structure 1A separated in this area with the help of the caterpillars 10 of the intermediate vehicle 30.

However, in a variant of FIG. 35 (not shown)

Post 400 here also with part 1A of the supporting structure by means of a height adjustment device for this Post be connected, in the manner of the adjusting device 39 described with reference to FIGS. 6 and 7, but with a single sliding column in order to avoid the use of the caterpillars 10 of the intermediate vehicle 30 and so with each operation of standing or picking up the intermediate bogie 31 energy to save.

Within the scope of the invention, further not shown Variants are applied.

So the machine can be trained independently for long journeys by equipping its end vehicles with bogies, Clutches, brakes and motors are equipped as described above for the empty run. In In this case, the height adjustment of the caterpillars 10 can be reduced for all of their vehicles and for the Laying and dismantling work is a useful measure compared to that for loading the machine on a train Platform freight wagons must be limited to the necessary stroke. The assembly of the axles 15 of the bogie 9 of the two end vehicles, which allows their height adjustment relative to the chassis 11 carrying them, is not indispensable if there are large distances between

these axles and the caterpillars 10 of the vehicles are undesirable, such as when the machine is only used for independent procedures over very short distances and when their transport is over

long distances on a train from low-rise 30

Platform carriage takes place.

One of the two end vehicles can only contain one bogie, excluding caterpillars 10. In this one In this case, the dismantling and laying is done in a single direction and the machine must necessarily

se with lateral support devices in the described Type or some other known construction that is connected to lifting devices can be to enable gripping and picking up of a track connection placed next to the track, without throwing the machine off balance. The lateral displacement of this machine by their caterpillars is then no longer possible. Always for this same case it should be noted that leaving it standing of the intermediate vehicle 31 is always possible on the track where the track connection or the transported Track section is shorter than the distance between the two end vehicles by a length that this Bogie, because you can no longer bridge the bogie to get it under the machine remove.

The two elements of the intermediate support 8, the tracked vehicle 30 and the bogie 31 can either both on one of the parts of the supporting structure, as shown in the described embodiment is, be arranged, or one on one of the two parts and the other on the other part. By doing However, the embodiment creates the possibility of combining these two elements on the same part using this part in an independent way without attaching the other if its length between the supports is sufficient for laying or removing a section of track or one Rail connection of a smaller extent. For such a one In the case of the universal joint 3 can be dismantled.

If it is deemed necessary, it is possible the pulling in of the two posts 40 of the suspension device 37 upwards with the aid of piston-cylinder units provide, for example, to the

Maneuver when gripping a track connection placed next to the track on which the machine is standing facilitate. In this case, the two posts can be pivoted in a vertical plane across the track arranged at the end of the upper cross member 38.

Finally, the conception of the machine according to the invention enables transport, laying and the dismantling of very long railway materials, such as assembled sections, by increasing the number of articulated parts forming the supporting structure. The supporting structure in this case also has an intermediate support 8 near each of its universal joints 3 on.
