    -1 Device and Gantry for Suspending a Component The present invention relates to a device for suspending components, in particular cameras, radar devices, laser scanners or the like, from a gantry, which spans 5 a road, for example. The invention further relates to a gantry equipped with such a device. Gantries that span roads frequently carry heavy and complex components of the type mentioned above, which not only must be securely anchored in a suspended or salient position, but also require repeated cleaning, maintenance and adjustment. So as 10 to gain temporary access to the components for these purposes, at present either the road must be blocked, or the maintenance staff must let themselves down from the gantry in a secured manner, or complicated mobile suspension constructions are required. Any discussion of documents, acts, materials, devices, articles or the like which 15 has been included in the present specification is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present disclosure as it existed before the priority date of each claim of this application. Throughout this specification the word "comprise", or variations such as 20 "comprises" or "comprising", will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps. According to a first aspect of the invention there is provided a device for suspending at least one component from a gantry, comprising: 25 a guide rail that can be secured on the gantry in an approximately vertical orientation; a carriage, which is guided on the guide rail in a sliding movable manner and on which the component can be mounted; and a limit stop, which is mounted on the guide rail beneath the carriage in a height 30 adjustable manner; wherein the guide rail is divided into a lower part and an upper part, which are connected to each other by way of a pivot connection having a pivot axis parallel to the longitudinal direction of the guide rail. The component can thus be moved by way of the carriage from a lowered 35 mounting and operating position into a raised maintenance, cleaning and adjustment position, in which it can be easily accessed or reached from the gantry, without the -2 need for the operating staff to take safety measures for outside work on the gantry or requiring access from beneath and the resulting road block. The limit stop, which is mounted on the guide rail in a height-adjustable manner, defines the position of the carriage, and thus of the component, in the lowered mounting and operating position, 5 which can thus be easily preselected and reproduced at any time. When the carriage is moved into the raised position on the upper part, the carriage can be pivoted together with the upper part, while the lower part remains rigidly secured to the gantry. The carriage can thus be pivoted into a position that faces the user by way of the gantry, which further facilitates access to the component for maintenance, cleaning and 10 adjustment work. The pivot axis of the pivot connection is preferably located outside the guide rail, so that the lower part and the upper part can be pivoted into and out of alignment, whereby the carriage that has been raised into the upper part can be pivoted even more closely toward the user. 15 It is particularly advantageous for the upper end of the guide rail to carry a block and tackle and/or a winding drum for a pull cable engaging on the carriage, which considerably facilitates the raising of the carriage. According to a further preferred embodiment, the guide rail comprises at least two laterally projecting flanges and the limit stop comprises at least two L- or U-shaped 20 lugs, which embrace the flanges with play, wherein the limit stop includes at least one movable clamping element for locking the play. The limit stop can thus be fixed at the desired height so as to define the lowered position of the carriage with the component. The clamping element is preferably a wedge, which is linearly guided in the limit stop so as to be seated against the guide rail and which is penetrated by a tension 25 screw, which drives the wedge between a surface of the limit stop and the guide rail upon tightening. This allows the limit stop to be clamped at any arbitrary height quickly and securely. Because of the selected wedge shape, the limit stop is clamped at the desired height even without tightening of the tension screw; the tension screw amplifies the effect of the wedge-shaped clamping element and provides additional securing 30 action. It is particularly advantageous if the tension screw can be accessed from the top side of the limit stop. The limit stop can then be moved directly from the gantry during operation, for example for adjustment purposes. According to a further advantageous embodiment of the invention, the guide rail 35 comprises at least two laterally projecting flanges, and the carriage comprises at least four pairs of rollers, of which two pairs engage one flange and two pairs engage the -3 other flange, respectively, and roll thereon. This results in very stable and precise guidance of the carriage, which allows exact orientation of the component, for example a camera or scanner. It is particularly advantageous for the cross-section of the guide rail to be a 5 double-T profile, wherein the limbs of the one T form the two flanges and the limbs of the other T can be secured to the gantry, resulting in high load-bearing strength and torsional rigidity. Preferably one of the components that are the carriage and limit stop has at least one centering hole, and the other component has at least one preferably truncated cone 10 shaped, and particularly preferably additionally obliquely positioned, centering pin, which can be engaged in the hole. When the carriage is lowered onto the limit stop, this results in self-centering and self-adjustment of the carriage in a defined, reproducible position on the limit stop, simultaneously fixing the carriage by way of pressing against the guide rail. The preferred oblique position of the centering pin increases the pressing 15 action. The use of more than one centering pin allows additional fixation of the carriage to prevent rotation. According to a further preferred embodiment of the invention, the guide rail may also guide more than one carriage. To this end, the carriage can preferably be coupled to another carriage by way of a centering coupling. The carriages can thus be 20 lowered consecutively on top of one another, in each case centering one another against each other in defined, reproducible positions. In a further aspect, the invention creates a gantry, which is equipped with the device of the type described here, which is secured to the gantry by way of an approximately vertically oriented guide rail. 25 The gantry preferably has a walk-on catwalk that is secured by a lateral railing, wherein the guide rail runs vertically downward outside the railing. The guide rail can thus easily protrude downward beneath the catwalk or beneath the gantry so as to suspend the component or components, while the user can stand securely on the catwalk behind the railing. 30 It is particularly advantageous to use a two-piece guide rail that is equipped with a pivot connection for this purpose, wherein the pivot connection is located at or above the height of the railing and the lower part of the two-piece guide rail is secured to the gantry or the railing thereof. The upper part of the two-piece guide rail can thus be pivoted over the railing into the region above the catwalk, wherein the component can 35 be easily accessed for maintenance, cleaning or adjustment purposes with the carriage -4 that has been transferred to the upper part, without the user having to leave the secure catwalk. The device is suitable for any type of gantry and component. The gantry is preferably a gantry that spans the road for traffic monitoring purposes, and the 5 component is a camera, a radar device or a laser scanner. The invention will be described in greater detail hereafter based on an exemplary embodiment, which is shown in the accompanying drawings. In the drawings: FIG. 1 shows a perspective overview of the gantry of the invention, comprising 10 a plurality of devices according to the invention; FIG. 2 is a side view of the devices of FIG. 1; FIGS. 3a and 3b show top views onto the device of FIG. 2 in two different operating positions; FIG. 4 shows a perspective view of a portion of the device of FIG. 2; and 15 FIGS. 5a and 5b show a top view (FIG. 5a) and a sectional view (FIG. 5b) along the intersecting line A-A of FIG. 5a of the limit stop of the device of FIGS. 2 to 4. FIG. 1 shows a gantry 1, which spans a road 2 having one or more lanes 2', 2", 2' and is used to suspend components 3 such as cameras 3', laser scanners 3", radar devices (not shown) or the like. The term "suspension" in the present description shall 20 be understood to include projections or mountings at approximately the height of the gantry 1, which is to say the components 3 do not necessarily protrude downward below the underside 4 of the gantry 1, in particular if the gantry 1 has a large installation height h. The gantry 1 has a catwalk 5, which is secured by one or more lateral railings 6. 25 The catwalk 5 can be reached from the ground via a ladder 7. The gantry 1 further has one or more devices 8 for anchoring or suspending one or more components 3, respectively. The devices 8 are secured to the gantry 1 laterally outside the railing 6 and one of the devices 8 is shown in detail in FIGS. 2 to 5. According to FIGS. 2 and 4, the device 8 comprises a guide rail 9, at least one 30 carriage 10 guided thereon in a sliding movable manner, and a limit stop 11, which is mounted on the guide rail 9 beneath the carriage 10 in a height-adjustable manner (FIG. 5). The guide rail 9 is secured to the gantry 1 in an approximately vertical orientation, which is to say with the longitudinal and guide axis 12 in an approximately vertical position, for example by way of anchor brackets or anchoring pins 13 on the gantry 1 35 and/or the railing 6 thereof -5 As is shown in FIGS. 2 and 3, the guide rail 9 is preferably - although not necessarily - divided into two parts, and more particularly into a lower part 9', which is rigidly secured to the gantry 1 or the railing 6 thereof, and an upper part 9", which is pivotably connected, preferably rotatably by 360", to the lower part 9' by way of a pivot 5 connection 14. The pivot connection 14 has a pivot axis 15 that is parallel to the longitudinal direction 12 of the guide rail 9. As is shown in FIG. 3, the upper part 9" of the guide rail 9 can thus be pivoted from a position that is aligned with the lower part 9' (FIG. 3a) into a maintenance position that is rotated over the railing 6 and the catwalk 5 (FIG. 3b). If - as will be described in greater detail below - the carriage 10, together 10 with the component 3, is located on the upper part 9", the component 3 can be moved into the secure working area of the user on the catwalk 5 for maintenance, cleaning and adjustment purposes. In the embodiment shown, the cross-section of the guide rail 9, or the parts 9', 9" thereof, has a double-T profile ("H-profile"), wherein the limbs 16, 17 of the one T 15 form two of the flanges facing away from the gantry 1 for the carriage 10 to roll on, and the limbs 18, 19 of the other T form two mounting strips for securing to the gantry 1 or the railing 6, for example for the engagement of the anchor bracket and anchoring pins 13. The flanges 18, 19 can also be used to anchor the pivot connection 14, which comprises mounting brackets 20, 21 for mounting a pivot pin 22. The rotational axis 15 20 of the pivot connection 14 is thus located outside the guide rail 9, which extends the effective swivel arm during pivoting (FIGS. 3a and 3b) and thereby improves reachability of the component 3 in the maintenance position (FIG. 3b). The carriage 10 is guided in a sliding manner on the guide rail 9, or more precisely on the outer flanges 16, 17. To this end, the carriage 10 can support at least 25 three, preferably four or more roller pairs 23, which each engage a flange 16, 17 between each other and roll thereon, which is to say two (mutually spaced) roller pairs 23 for the one flange 16 and two (mutually spaced) roller pairs 23 for the other flange 17. The carriage 10 forms a mounting platform 24 for attaching the component 3, for example by way of appropriate mounting brackets 25, which can be anchored in 30 boreholes of the platform 24 by way of screws 26. Using a pull cable 27, which engages on an eyelet 27" of the carriage 10 by way of a carabiner 27' for example, a user on the catwalk 5 can move the carriage 10 from a mounting position that is lowered onto the lower part 9' into a maintenance position that is raised onto the upper part 9", and vice versa. For operating the pull cable 29, the 35 upper end of the guide rail 9 preferably carries a block and tackle, a deflection roller 28 and/or a winding drum 29, which can be actuated by an electric motor or a crank 30 so -6 as to wind up and unwind the pull cable 27. The pull cable 27 is a steel wire or cable, for example, however variants such as chains, plastic cables or the like are also covered. In the lowered position, the carriage 10 is supported downward and secured by 5 the limit stop 11. The limit stop 11 can be fixed on the guide rail 9 at any arbitrary height and thereby defines the lower final position of the carriage 10, and thus the mounting height of the component 3. Beneath the limit stop 11, at the lowest end of the guide rail 9, the rail can additionally be provided with a stopper 31 so as to basically act as a "retainer" during mounting, preventing the limit stop 11 or carriage 9 from sliding 10 downward. FIGS. 5a and 5b show an embodiment of the limit stop 11 in detail. By way of two L- or U-shaped lugs 32, the limit stop 11 embraces the flanges 16, 17 of the guide rail 9 and slides thereon with play. The play can be locked at any time using a clamping element, for example a screw or the like, mounted movably on the limit stop 11, so as 15 to clamp the limit stop 11 at the desired height. The clamping element is preferably formed by two wedges 33 as shown, which on the one wedge side 34 can be seated against the guide rail 9 and on the other wedge side 35 slide along an oblique inner surface 36 of the limit stop 11 and are penetrated by a tension screw 37. Due to tightening of the tension screw 37, the wedge 33 slides upward and along the oblique 20 surface 36, whereby the wedge is basically driven between the outer side of the guide rail 9 (or the flanges 16, 17 thereof) and the inner surface 36 of the limit stop 11. The tension screws 37 of the wedges 33 can preferably be accessed from the top side 38 of the limit stop 11 and can be actuated by the operating person on the catwalk 5, for example by way of along wrench. The limit stop 11 has an eyelet 39 for this 25 purpose, through which a holding rope can be temporarily guided so as to lower the limit stop 11 to the desired height, whereupon the tension screws 37 are tightened in order to clamp the limit stop 11 at this height. The holding rope guided through the eyelet 39 can then be removed. Thereafter, one or more carriages 10 can be threaded onto the guide rail 9 or the 30 flanges 16, 17 thereof and lowered by way of the pull cable 27 until these are seated on or strike against the limit stop 11. The seat between the carriage 10 and the limit stop 11 can be defined in terms of the position thereof in the lateral direction by way of a centering coupling 40. The centering coupling 40 comprises, for example, a conical, preferably truncated cone 35 shaped, centering pin 41 on one of the parts that are the carriage 10 and the limit stop 11, and a matching centering hole 42 on the respective other part. It is further possible -7 to provide more than one centering coupling 40 between a carriage 10 and the limit stop 11 (not shown), so as to define the angular position between these. It is also possible to center or orient a plurality of carriages 10 that are located on top of one another with respect to each other by way of interposed centering 5 couplings 40, as is shown in FIG. 4. To this end, the centering coupling 40 can additionally comprise a centering spacer pin 43, which extends the centering pin 41 and engages in the centering hole 42 of the respective other part. If the component 3, for example a laser scanner 3", is to be secured in the upper part 9" of the guide rail 9, which is to say it does not have to be lowered, it is also 10 possible, instead of a limit stop 11, to use another device for fixing the height of the carriage 10 on the guide rail 9, for example the carriage 10 can be screwed on directly at the desired height of the guide rail 9 or fixed by way of a holding plate that is screwed onto the guide rail 9. The invention is not limited to the shown embodiments, but encompasses all 15 variants and modifications that are covered by the scope of the accompanying claims.
