forms movable parts of the device, the stationary component 2o having brackets 24, n.it which it connected to the already set expansion arches Io and 12 will. This is shown in the drawing, the last extension arch 14 set remains free. It goes without saying that the consoles 24 could also be connected to other fixed components, such as pre-seized Carrier, if any. In any case, the arrangement should be such that the gear box 18 in a is located in the upper position of the line.

The chassis 22 has two cantilever beams 26 and 28 which extend in the longitudinal direction and which are supported by a transverse yoke 3o are connected to each other. End consoles 32 and 34 on each cantilever beam 26 also belong to the chassis 22 or 28, which carry a sliding tube 36 which is guided in associated bearings of the stationary component 2o, the cantilever beams 26 and 28 extending below the stationary member 2o. As a result, the landing gear move relative to the stationary component 2o in the longitudinal direction, namely within the through the end brackets 32, 34 set limits. A hydraulic lift cylinder 38 is articulated at one end to a bearing stored on the stationary component 2o and at its other end via a bearing 42 on the chassis 22. This Lifting cylinder 38 is used to move the chassis 22 in the longitudinal direction.

This results from the arrangement of the wheel 78.

A device for actuating the lifting cylinder 38 for moving the chassis is not shown 22 and a device for actuating the Huczvinder 6o of the lifting device. This facility can be automatic or controlled by hand. Consoles, not shown, can also be used for hanging of the gear box by an overhead rail or another overhead Component be provided.

During operation, after the extension arch 16 to be set has been positioned, the chain 62 and the fork are lowered 62 connected to the bracket 66 in the middle of the extension arch 16, which at this time was still on the Lying the route lies. Then the lifting cylinder 6o of the lifting device is actuated and the chain 62 begins, to lift the expansion arch 16. This state is shown in FIG.

The Sueuer arms 46 and 48 are in Figure 1 in their lower Position and shown in Figure 2 with solid lines in their lower position. You take this rest position due to their own weight. When the expansion arch 16 is partially raised, the bearing shells 54 of the two control arms 46, 28 detect this, as shown in FIG. 2. Because the fork 64 is in the middle of the arch engages and the control arms 46 and 48 are arranged at equal lateral distances from the chain 62, accordingly grip the bearing shells 54 on similar ones Put the bow on.

The lifting movement then takes place by further extending the lifting cylinder 60. The fork 64 does not move, however more vertically but on an upward and forward arc according to the swivel movement of the control unit arms 46, 48 around their associated pin 5o and 52, respectively. During this later section of the lifting movement of the upper part of the extension arch 16, its movement is controlled very precisely> because it is held in three places, namely on the two bearing shells 54 and on the Fork 64. As a result, it is not necessary to manipulate the extension elbow 16.

The extension arch 16 then reaches its fully raised position, such as that with the reference symbol 16a in FIG. 2 is shown, with its top lying just below the hanging wall of the track and its supports essentially hang vertically downwards. By setting the gear box 18 beforehand, it is ensured that in this fully raised position of the extension arch 16 closer to the extension arch that was set last 14 is as required to form a correct vault between the extension arches 14 and 16. The lifting cylinder 38 is then extended and moves the undercarriage 22 forward, with the one in the bearing shells 54 held expansion arch 16 is brought into its correct position. In this raised position extends the longer finger 26 of each bearing shell 54 in the vertical direction, while the shorter finger 58 is in the extends substantially horizontally. This ensures that the forward movement of the chassis 22 also is transferred to the expansion arch 16.

In this state, foot parts or the like can be placed under the vertically hanging supports of the extension arch 16 in conventionally be set in order to press the support arch tightly against the hanging wall of the route and to put it completely. Thereafter, the bearing shells 54 can be removed from the extension sheet, so that the Control arms 46 and 48 fall to their lower rest position while, in a similar manner, fork 64 and bracket be released from the extension sheet. The expansion arch 16 is then set.

To set the next expansion arch, the gear box is moved forward to expansion arches 12 and 14. When the gear box 18 is suspended from a rail, the brackets 24 of the expansion arches 1o and solved. Before the fork 64 is released from the expansion arch 16, the lifting cylinder 38 is retracted, whereby it is the stationary Part 2o pulls forward on the sliding tube 36 until it is below the expansion arches 12 and 14, to which the consoles 24 can then be connected in order to define the new position of the stationary component 2o. It should be noted, however, that the gear box need not necessarily be suspended from a rail. It can also be arranged at the head of a re-tearing machine or, if available, at an overhead position Supports or the like be attached in such a way that displacement and clamping is possible.

In the preceding description of the mode of operation it was assumed that the control arms 46 and 48 initially be pivoted to their upper position and then to
