    BRIDGE SYSTEM
    The present invention generally relates to a bridging system and a method of bridging a space, and finds particular, but not exclusive, utility in temporary bridges that can be transported in disassembled form for assembly and subsequent use without the need hoist.
    In military situations, if soldiers need to cross a space such as a ravine or marsh without going down and up on the other side, it is known to use ropes to set up a so-called zipline crossing. However, they are slow to cross and the first person must cross without the rope being anchored correctly on the other side.
    Bridges are well known but are typically either too heavy to transport, requiring vehicles and the like, or require expensive equipment for construction and lifting devices, such as cranes, for installation.
    It is desirable to have a bridging system which can be carried by one or more persons and which is assembled and installed relatively easily.
    According to a first aspect, the present invention proposes a bridging system characterized in that it comprises a bridge and a trolley, the bridge comprising a bridge deck having at least two preformed bridge sections, each bridge section having a rigidity structure provided by at least two longitudinal members connected together by at least one bridge piece, and connecting means for releasably connecting together the at least two bridge sections, the carriage comprising a set of wheels having a path configured in such a way that that in use with the carriage located on the bridge deck, at least one wheel is in contact with a first spar and at least one other wheel is in contact with another spar, the system further comprising guiding means for maintaining the at least one wheel in contact with the first spar and to maintain the at least one other wheel in contact with the other spar so that the carriage and the apron of bridge remain in contact while moving relative to each other or with each other, for the launching of the bridge deck over a space through which the bridge is to be made, the carriage being configured to transport goods and / or personnel on and along the deck deck after the deck has been positioned above said space.
    In use, the bridge sections can be transported separately and connected together as needed. The carriage can be used to launch the bridge over space in a substantially horizontal manner. Inclined launches are also possible with sufficient numbers. The same or a different cart can then be used to cross the bridge and carry men and equipment. In its simplest form, the bridge sections may be ladders, the connecting means allowing them to be connected together. Ladders may include aluminum or similar lightweight materials, including advanced composite materials. The bridge sections may have a uniform width to then allow the carriage to roll over them.
    The term "preformed" for bridge sections may mean preassembled. Alternatively, each bridge section may have been manufactured as a unitary piece.
    The bridge deck may have a width in the range of 20 cm to 100 cm. The bridging system can be arranged to allow a weight of at least 50 kg to pass on it when installed.
    The deck apron may have an apron plane extending parallel thereto and in which the at least two side members both extend, and the system may further comprise at least one apron column adapted to extend out of the deck plane, opposite the deck deck, and at least one cable to connect the bridge deck to the at least one deck column. The at least one deck column may be adapted to extend opposite the deck deck at an angle between 40 degrees and 140 degrees relative to the deck plane.
    This column can allow a triangular lattice shape to be created with it and the cable attaching to the bridge deck. The bridge may be assembled with the substantially horizontal deck plane and the column projecting upwardly therefrom. Alternatively, the bridge may be assembled with the deck plane that is vertical and the column that extends outward horizontally on one side. After assembly, the bridge can be slid on the carriage and above the space. The bridge can then be turned 180 degrees if the column was above the deck, or 90 degrees if the column was on the side, so that the column is now below the deck. In this way, the column will not hinder the movement of the carriage on the upper surface of the deck. In other words, the at least one column may be disposed on the side of the deck deck opposite the side / surface of the deck to be used by the carriage.
    The at least one column is releasably attachable to the bridge deck. For example, nuts and bolts, cotter pins, or a simple push fit fitting can be used to secure it. The column can be initially separated so as to increase the ease with which the various parts of the bridge can be shared between the users.
    The at least one column may be releasably attachable to at least one bridge section, for example at one end of at least one bridge section. Other locations are contemplated, such as a point midway across the bridge section.
    The at least one column may be adapted to be pivotally attached to the bridge deck, or at least one deck section. For example, it may be pivotally attached to one end of at least one bridge section. In this way, the bridge could be assembled more quickly. Means for locking the column in a certain position relative to the deck plane may be provided, such as cotter pins, simple push-fit fittings and the like.
    The connecting means for interconnecting the at least two bridge sections may comprise a hinge such that in a first position the at least two longitudinal members of each bridge section extend immediately adjacent to each other. other, and that in a second position, the at least two longitudinal members of each bridge section are linearly aligned with each other. For example, a folding ladder can be used to reduce assembly time. Means for locking the bridge sections in certain positions relative to each other so as to create a flat bridge deck may be provided, such as cotter pins and the like.
    The at least two longitudinal members may be linearly hollow and the connecting means for interconnecting the at least two bridge sections may comprise an element configured for insertion into one end of two linearly adjacent longitudinal members. For example, sectional aluminum ladders are typically hollow. The connecting member may be a rod or hollow member having a cross-section that fits snugly in the end of each ladder box section and extends within each end of each spar adjacent to about 10 mm to 400 mm. The link member may include a quick-release fastener by thumb pressure to allow it to be removed from the ends of the ladder to minimize ladder lengths during transit. Longer lengths help prevent the separation of adjacent spars by the inclusion of retaining members such as pins or the like passing therethrough. Shorter connecting members may rely on external retainers such as clips, straps, or the like.
    The bridging system may further include a launching front section releasably attachable to one end of the deck deck to assist in launching the deck over the space through which the deck is to be made. This may take the form of another bridge section or a rod or other rigid linear element that allows the other side to be reached while a longer bridge length remains on the launch side. The launching front section guarantees landing on the opposite side while a substantial part of the total length of the bridge remains on the near side. This helps prevent the deck from tipping during launch and helps the structure cope with the maximum effects of the launch load. The total length of the bridge, including the launching front section, may be arranged in such a way that the part between the two nearest columns remains on the near side at all times until the forward section has reached the opposite side. . It may be preferable for this part to remain as distal, with respect to the space across which the bridging is to be made, as compared to any trolley used to assist the launch.
    The launching front section can assist in the subsequent rotation of the deck after it has been pushed to the end so that the deck deck rests on both sides of the space. The launching front section can be telescopic or include tapering sectional tubes.
    The bridging system may further comprise a rear section adapted to be releasably attached to one end of the bridge deck to load the deck to assist in launching the deck over the space through which the deck must be achieved, reducing the weight of counterweight required to balance the structure. This may take the form of another bridge section or a beam or other rigid linear element that allows the near end of the bridge to be weighed down to prevent the bridge from tipping over and into the space before the other side is reached during the launch. The rear section may be telescopic or include tapered sectional tubes.
    The deck apron may have an apron plane extending parallel thereto and wherein the at least two side members both extend, and the system may further comprise at least one side column adapted to extend opposite the bridge deck substantially parallel to the deck plane, and at least one cable being disposed on one side of the bridge deck by the at least one side column. This side column can allow a triangular lattice shape to be created with it and the cable on the side of the deck deck. Alternatively, the side column may extend from the deck deck in a direction not parallel to the deck plane, for example at an angle in the range of 5 degrees to 50 degrees below the horizontal.
    The bridging system may further comprise a stabilizer adapted to be disposed on either one or both ends of the deck section. The stabilizer may comprise a rigid linear element arranged with its longitudinal length parallel to the deck plane and perpendicular to the longitudinal length of the deck deck. It can act to improve the stability of the bridge in use to prevent tilting or overturning thereof.
    Each of the at least two bridge sections may include ladders.
    The bridging system may further comprise at least one side column adapted to extend opposite the side of the deck and at least one cable intended to be arranged on one side of the deck deck by the at least one column lateral, the cable being adapted to be fixed at its two ends to the bridge deck on each side of the side column.
    According to a second aspect, the invention proposes a bridging system comprising a bridge and a trolley, the bridge comprising a bridge deck having at least two preformed bridge sections, each having at least two spars, the at least two spars being connected together by a bridge piece, the at least two bridge sections being connected together by connecting means, the carriage comprising a set of wheels having a path configured so that in use with the carriage located on the bridge deck at least one wheel is in contact with a first spar and at least one other wheel is in contact with another spar, the system further comprising guide means for holding the at least one wheel in contact with the first spar and for maintaining the at least one other wheel in contact with the other spar such that the carriage and the bridge deck remain in contact while moving relative to one another or the one with the other, for the launching of the bridge deck over a space through which the deck is to be made, the carriage being configured to carry goods and / or personnel on and along the deck deck after the bridge has been positioned above said space.
    In this aspect, the bridge has been assembled or is supplied already assembled. This can happen in situations where the space to be crossed is relatively narrow, so that an assembled bridge can be transported by the users. The following features have the same features and benefits as described above.
    The deck apron may have an apron plane extending parallel thereto and wherein the at least two side members both extend, and the system may further comprise at least a first apron column extending outside the deck plane, opposite the deck deck, and at least a first cable connecting the bridge deck to the at least one first deck column, the at least one first cable being fixed at both ends to the deck bridge on each side of the at least a first apron column.
    The at least two longitudinal members may be linearly hollow and the connecting means connecting together the at least two bridge sections may comprise an element introduced into an end of two linearly adjacent longitudinal members. Alternatively, or in addition, an outer sleeve, or outer clip, may be used as connecting means.
    The bridging system may further include a launch front section releasably secured to one end of the deck deck to assist in launching the deck over the space through which bridging is to be made. The bridging system may further include a rear section releasably secured to one end of the deck deck for loading the deck deck to assist in launching the deck over said deck. The bridge deck may have a deck plane extending parallel thereto and wherein the at least two side members both extend, and the system may further include at least one side column extending to the deck opposite of the bridge deck substantially parallel to the deck plane, and at least one cable disposed on one side of the bridge deck extending around the at least one side column and fixed at its two ends to the deck of bridge on each side of the side column. Alternatively, the side column may extend from the deck deck in a direction not parallel to the deck plane, for example at an angle in the range of 5 degrees to 50 degrees below the horizontal plane. . The bridging system may further include a stabilizer releasably secured at or near one or both ends of the deck section.
    The at least one bridge section may comprise at least two bridge sub-sections connected together by connecting means, and at least one second deck column may be disposed at or near each junction of the bridge sub-sections, extending beyond the deck plane and away from the bridge deck, the at least one second apron column being substantially shorter than the at least one first apron column, the system further comprising at least one second cable or rod suspended above deck deck by the at least one second apron column, the at least one second cable or rod being fixed, at its two ends, to the bridge deck on each side of the at least one second bridge column.
    The at least one second cable or rod may be attached to the bridge deck at or near each end of the bridge subsection. Any of the at least one first or second deck columns may be able to extend opposite the deck deck at an angle between 40 degrees and 140 degrees relative to the deck plane.
    In a third aspect, the invention proposes a method of bridging a space characterized in that it comprises the following steps: arranging a bridging system according to the first aspect; assemble the bridge on one side of said space; place the carriage with the wheels above and slide the assembled bridge over said space until the bridge spans said space.
    In a fourth aspect, the invention proposes a method of bridging a space comprising the following steps: arranging a bridging system according to the first aspect; assemble the bridge on one side of said space; place the cart with the wheels underneath; place the bridge on the cart; and rolling the assembled bridge over said space until the bridge spans said space.
    In a fifth aspect, the invention provides a method of bridging a space comprising the steps of: arranging a bridging system according to the first aspect; partially assembling the bridge on one side of said space; placing the carriage with the wheels above and sliding the partially assembled bridge over said space, and adding other bridge sections, columns, and tension members, and continuing the launching of the extended deck structure to the bridge spans the space.
    In any of the third to fifth aspects, the space can be passed relatively reliably and easily from one side. The step of sliding or rolling the assembled bridge over the space can be undertaken with the at least one apron column above or parallel to the horizontal, and the method can further include the a step of rotating the bridge, such that the at least one column is under the bridge deck, after the bridge has been arranged to span the space.
    The method may further include the step of arranging a carriage to move on the upper surface of the deck deck to thereby move goods and / or personnel from one side of the space to the other.
    Thus, a method of bridging a space is proposed according to the present invention, characterized in that it comprises the following steps: a) arranging a bridging system as defined above; b) assemble the bridge on one side of said space; c) place the carriage with the wheels on top and position, or assemble, the bridge on the wheels of the carriage; and d) sliding the bridge over said space until the bridge spans said space.
    The foregoing and other features, features, and advantages of the present invention will be apparent from the following detailed description when taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the present invention. the invention.

    The terms upper, lower, over, under and the like in the description are used for descriptive purposes and not necessarily to describe relative positions. It is understood that the terms so used are interchangeable under appropriate circumstances and that operation is possible in orientations other than those described or illustrated herein.
    The principles of the invention will now be described by a detailed description of at least one drawing relating to examples of features of the invention. It is clear that other arrangements can be configured according to the knowledge of those skilled in the art without departing from the scope or technical teaching of the invention.
    Referring to Figure 1, it can be seen that a bridging system 10 is shown extending partially over a void defined by two opposite supports 20, 30. The bridging system comprises an apron bridge 40 having two sections 42 connected together at one of their ends. The two sections 42 have similar lengths, although this is not necessarily the case. They are rectangular in plan with two long sides and two short sides. The two sections are assembled together at their small sides 44.
    An apron column 50 is disposed vertically upward from the central point 44 of the bridge deck 40. Although shown as extending from the center point of the deck deck, other positions are contemplated. Although shown as extending upward perpendicular to the deck deck, it is understood that it could extend at other angles, such as between 40 and 130 degrees, between 50 and 120 degrees, between 60 and 110 degrees, or between 70 and 100 degrees. It is attached to the bridge deck 40. The attachment may be made as part of the connecting means used to assemble the adjacent deck sections, although other means, such as bolts, or push-fit fittings, connecting directly the apron column to the deck are also considered.
    A cable 60 is arranged to pass over the top 55 of the deck column, or to connect to said top 55. The cable 60 is fixed at 65 and 68 to the bridge deck 40 at each end thereof. The link may be inwardly shifted towards the central point 44, instead of being at the end of each end, so as not to lock with the supports 20, 30 when the bridge is turned over.
    The cable 60 may be attached to the top of the deck column 50 or may simply rest thereon, possibly with the use of a pulley or a bridge. The cable 60 can be a rope, a chain, a wire, a strap, or any other inextensible flexible element. Alternatively, it may be an axially rigid element such as a rod or a series of rods.
    In use, the bridge 10 is assembled on one side 20 of the space through which the bridge is to be made (vacuum 99). The carriage 70 is placed near or at the edge of the support 20 and the bridge 10 is placed thereon, with the deck column 50 above the deck 40. Alternatively, the bridge 10 can be placed such that the apron column 50 projects approximately horizontally.
    The bridge 10 can be assembled on the carriage to avoid having to lift it to place it on the carriage.
    The carriage 70 is typically provided with wheels above it, so that it remains stationary relative to the support 20.
    The bridge 10 is then pushed over the vacuum 99 using the wheels of the carriage to move the bridge relatively easily. The bridge can also be incrementally constructed as it is pushed over the space through which the bridge is to be made.
    Once the far end of the bridge has reached the other side of the vacuum 99, so that the end of the bridge deck 40 rests on the support 30, the bridge can be rotated about an axis passing through through its longitudinal length and extending substantially horizontally. The bridge 10 will then appear similar to that shown in FIG. 2.
    It is envisaged that the rotation of the bridge about its longitudinal axis can occur in two stages. A first 90 degree rotation when the far end of the bridge (or the launching front section, if provided) has just reached the far side, followed by another 90 degree rotation when the deck has progressed further, such so that, if it is planned, the whole front section is on the far side. Alternatively, the bridge can be completely rotated 180 degrees after the front section is on the far side.
    The carriage 70 can then be removed from below the near end and placed on the bridge deck 40 so that it can be moved along it to transfer men and equipment to the other side. . In some situations, the truck may not be required to launch the bridge. Instead, the bridge can be slid directly onto the ground, for example if the friction characteristics allow it.
    Another example of a bridge system is shown in Figure 3. The bridge 100 has a bridge deck 140 that includes four bridge sections 142. Each bridge section 142 is assembled to the next adjacent section so that the four extend rectilinearly when in shape. The points of connection are referenced 144.
    A first deck column 150 projects downward from the center point of the deck, having a first height, and a second deck column 152 projects downward from the connection points 144 on either side of the deck. central point. The second two deck columns 152 have a shorter height than the first deck column 150, however it is understood that they may have the same height.
    A cable 160 passes over or is connected to the ends of the apron columns 150, 152 opposite the ends fixed to the bridge deck 140. The cable 160 is fixed to the bridge deck 140 at each end thereof, or is shifted inside, towards the central point, in a manner similar to that described with reference to FIG.
    Additional cables 165 are provided between the first deck column 150 and each of the second deck columns 152, in a cross shape, so that, for example and with reference to the second deck column shown on the left of the first apron column 150, a first additional cable 165 extends from the base of the second deck column (where it is fixed to the bridge deck 140) at the top of the first deck column 150. A second additional cable 165 s extends from the base of the first apron column 150 near or at the point of connection of the first deck column 150 with the bridge deck 140, at the top of the second deck column 152. This forms the shape of a cross so that multiple triangular shapes are created for the strength and rigidity of the bridge 100.
    The same is repeated with additional cables 165 disposed between the first deck column 150 and the other second deck column 152, which is located to the right of the first deck column 150 as shown in FIG. 3.
    The bridge 100 in FIG. 3 has been assembled with the first and second deck columns above or on the side of the bridge deck 140, then launched over the void, and then rotated so that the columns 150 , 152 are located under deck deck 140.
    In Figure 4, another bridge 200 is shown spanning a void. This bridge also has four sections 242 forming a bridge deck 240. However, each section 242 includes four subsections 246. Subsections 246 may be of equal length although other arrangements are contemplated. Each subsection is connected to adjacent subsections 246 linearly, as before, to create a straight bridge deck 240.
    At the junction 244 of each sub-section 246 in the length of each section 242, but not at the ends of each section 242, a third deck column 254 is provided. The height of each third deck column 254 may be substantially shorter than the first deck column 250 and the second deck columns 252. The height of each third deck column 254 may vary depending on its location in each section 242. For example, Figure 4 shows that the third apron column 254 in the center of each section 242 may be the highest with the third apron columns 254 disposed at adjacent junctions on each side which are slightly shorter. In this way, with an additional cable 267 disposed on the distal ends of the third apron columns and fixed at each end of each section 242, an "arc" shape is formed with the cable 267.
    However, an alternative layout is shown in the right section 242, where the third columns 254 are all approximately the same height. In this section, cables 268 pass over the tops of each third column and are attached to the bridge deck at the base of each adjacent column 252, 254, or at the end of bridge deck 240. This creates a layout This alternate arrangement may be used across the bridge in all sections, or in only one or more sections.
    The third columns 254 may be disposed remote from the junction 244 of each sub-section 246 in an alternative arrangement.
    The other aspects of the bridge 200 are similar to the aspects of the bridge 100 shown in FIG. 3, with a cable 260 disposed on the tops of the first and second deck columns 250, 252 and attached to the bridge deck 240 at each end of the deck. this, and intermediate cross cables 265 between the second apron columns 252 and the first deck column 250.
    It is possible to use the carriage to launch the bridges, the carriage being provided with its wheels below it, so that it moves on the ground with the bridge supported above it , so that the bridge and the carriage move together. A deck section can be placed on the ground so that the wheels of the truck roll on it in case the ground is soft, leading to the locking of the wheels. Alternatively, the wheels may have relatively large portions to distribute the weight of the bridge and avoid being blocked.
    In certain circumstances, the truck must be located under one of the deck columns and remain in that position while the deck is being launched to maintain the structural integrity of the deck. In addition, it may be necessary to use more than one cart at the same time, located at various points of the deck during launch.
    The bridge 300 of Figure 5 also has four sections; however, it also includes a rear section 376 on which a load 390 has been placed as a counterweight for launching. The rear section can be removably attached to an outer end of the deck deck in a continuous and straight manner. The bridge 300 also has a front section 377 at the end opposite the rear section. This extends from the bridge deck continuously and rectilinearly. The front section can be removably attached.
    The forward section 377 may allow the remote side 30 to be reached more easily and with less of the bridge 300 suspended above the vacuum. This increases the length of the bridge maintained on the near side, thus minimizing the stress induced in the structure.
    The front and rear sections are shown as telescopic elements, although other possibilities are envisaged, such as rigid elements.
    The bridge 300 of Figure 5 is shown resting on two carriages 370. The carriages 370 are shown with their wheels above them, but it is also possible to use them with their wheels below them. this is appropriate.
    A carriage 370 is disposed under the second apron column 352 closest to the launching side above the vacuum. It may be important to maintain this relationship during launch as much as possible for stability reasons.
    A guide rope 380 is also illustrated in Figure 5. This guide rope is attached to the front section 377 and passes over the top of the first and second deck columns. The other end may be held by launch-side personnel to help lift and guide the forward section towards the far side when it is launched. The guide rope may be used to slightly lift the forward section at least partially to counteract the natural bending of the launch before section due to gravity.
    Although not shown, other ropes can be attached to the front section and extend to the near side from where they can be pulled by personnel to help guide it horizontally. These ropes can be retained when the deck is turned over to act as shore-side guy cables to provide lateral stiffening to the structure in use.
    Figure 6 shows an embodiment 400 of the system in which the bridge deck 440 comprises two ladders 442 attached end-to-end by two "T" pieces 444 located one on each upright 443A, 443B (or spar). The two opposite arms of each "T" part are introduced into the hollow uprights with the third arm projecting upwards and away from the apron 440, on which an apron column 450 can be arranged.
    The deck column 450 is shown as another ladder section having the same width as the deck deck 440. The tower 450 may comprise hinged, hinged or interlocked sections for ease of transportation. V-shaped tapering columns or single-column columns, stiffened by hinge consolidations, are also contemplated as variants.
    A stabilizer 411 is provided at one end of the deck deck 440. It includes a pair of arms 413 that extend opposite the deck deck in the same plane as the deck deck and on each side of the deck. this one. These arms 413 may be an extension of the rungs 445 which extend between each upright 442. A connecting element 414 extends between the radially outer ends of the two arms 413 on each side of the bridge deck 440.
    Cables 60A, 60B are arranged to extend from one end of the apron 440 from each end thereof, and arranged side by side extending from each link member 413. at one end, intersecting one above the other and meeting at the top of the deck column 450, then extending to each post or connecting member 414 at the opposite end apron 440. Cables or ropes can pass around pulleys at their intersection with the apron column 450, or apron struts. Ropes may be anchored or tensioned using lockable pulleys or unidirectional clutches at their intersection with deck posts or studs. The anchor points can be adjusted by the arrangement of other pulleys or tackle systems.
    In Figure 7, a bridge system alternative 500 is shown in the inverted launch state. It comprises six bridge sections 542, a rear section 576 and a front section 577.
    Deck columns 550, 552 are disposed at the junction of the six deck sections, with the two outermost columns 552 having a reduced height compared to the three central columns 550 which are of equal height.
    Cables 565 are disposed in connection with the bridge deck 540 at the base of each deck column and with the ends of each deck column, creating a cross effect.
    The ends of each deck column 550, 552 are also connected together by additional sections of rigid members forming an upper deck column reinforcement 558. These rigid members may be additional deck sections 542 since they have the same width as deck deck. These can be scale sections.
    The bridge 500 also includes stabilizers 511 in the form of rigid elements projecting from the bridge deck 540 in a plane parallel to the deck deck. Pairs of stabilizers 511 are disposed on each side of the deck deck at the points where the three central apron columns meet the deck deck. The ends of each pair are spaced from each other at the ends of the bridge deck but meet at their other ends, forming a triangular shape. A rope or strut 512 is disposed from the point where each pair of outriggers meet and is attached to the nearest deck post at a height above deck deck 540.
    A cable 529 is disposed on one side of the bridge to extend from the bridge deck at a point where the first outer deck column 552 joins the deck deck, through the end of each pair of outriggers. and terminating at the point where the other outer deck column 552 joins the deck deck. Another cable is arranged on the other side of the bridge deck in a similar manner.
    These cables can be called "pulling cables" and act to oppose the lateral deformation of the structure in use and during the rotation / inversion that follows the launch. Figure 7 shows a particular pattern of tie-rods and struts. Other reasons are envisaged depending on the length of the span, the spacing between the first and second columns and the layout of the front launch section.
    Pairs of shorter extension stabilizers 513 are also provided at each end of the bridge structure, near the junction of the rear and front sections with the main deck 540. Cables 514 are fixed at the point where each pair is join and extend upward to the top of the nearest outer deck column 552 on the opposite transverse side of the deck deck to form a cross shape for further reinforcement of the deck structure.
    The outer deck column 552 closest to the near-end support 20 comprises an extension column 553 which increases its height beyond the height of the three central deck columns 550. It includes end-attached cables. of the rear section and crossing over its top and fixed to the upper deck column reinforcement 558. Additional cables are also attached to the rear section at one end and at the top of the extension column 553 at the other end, to provide support.
    A guide rope 580 is shown extending from the forward section, passing above the top of the nearest outer deck column 552, and then extending to the top of the next adjacent deck column 550 where it passes above (possibly via pulleys) before extending to the top of the extension column 553 at the other outer deck column 552, where it passes over, then extends to the near side where staff can hold it and use it to help lift the forward section during the bridge launch.
    The various stabilizers 511, 513 and cables 529, 514, 565, together with the deck columns, the bridge sections 542 and the upper deck reinforcement 558, all contribute to increase the torsional stability and structural integrity during the launch. and the reversal (rotation) that follows.
    During launching, a carriage (not shown) is disposed under, in 599, the outer deck column 552 which has the extension column 553 and moves with the deck when moved over the space across which bridging must be done.
    An example of a carriage is shown in Figure 8. The view is a bottom view showing the base 571 of the carriage 570, which is rectangular. Two sets of wheels 572, 573 are indicated as will be explained in more detail below.
    The carriage is disposed above the uprights 443A, 443B of a bridge deck formed of a ladder-type member. Ladder or interconnection elements (bridge pieces) 445 extend between them to define the shape of the ladder and the strength and stability of the ladder.
    The first set of wheels 573 has its axes of rotation in a vertical manner in use, so that the axes are perpendicular to the longitudinal length of the deck. The wheels are all disposed between the two uprights 443A, 443B and bear against their inner faces so that the carriage 570 can not move laterally relative to the deck.
    The second set of wheels 572 is disposed with the substantially horizontal axes of rotation in use, so that the wheels roll on and along the upper portions of the posts 443A, 443B.
    More or less than four wheels in each set can be provided. For example, three or six wheels can be used. Other means for keeping the carriage on the top of the apron and to prevent it from falling are envisaged, such as clamps that pinch under the uprights, or channels arranged on the upper parts and / or the lower parts of the uprights, forming lateral guides within which the carriage wheels move. The channels may be integral with the main deck spars, possibly formed in the main spar extrusions.
    Another method is to use wheels 672 having the shape generally indicated in Figure 9. Each wheel has two outer portions 676 with a first radius which is larger than a central intermediate portion 675 which connects the two outer portions. The central portion 675 has a width making it able to rest and move along the upper portion of the upright 443A. The outer portions 676 with their larger radius are on each side of the upright. Means for facilitating the rotation of the outer portions 676 where they come into contact with the sides of the posts may be provided, such as ball bearings, grease and the like. An axis 611 is shown partially, which can connect adjacent pairs of wheels.
    An alternative is a carriage wheel 772 shown in Figure 10, including a relatively wide inner portion 776 and an outer portion 775. The outer portion 775 is for rolling along the upper portion of the post 443A. The inner portion provides positioning against the inside of the post but also provides a surface on which the carriage can roll when disposed with its wheels below it. The wider portion will help distribute the weight of the trolley and deck during launch. An axis 711 is shown partially, which can connect adjacent pairs of wheels.
    Although bridges having only two or four sections have been described, it is understood that the number of sections can be any number. At the junction of each section may be arranged an apron column, although it may be arranged also, or instead, at other points of the bridge deck.
    The third apron columns may be arranged only on some or all sections of the deck.
    Rather than a single cable extending from one end of the bridge to the other, from one end to the other, and disposed above the tops of the first and second apron columns, individual cables may used, which extend only across each section or section. For example, a cable may be used to extend from the end of the deck deck to the top of the first of the second deck columns. Another cable may then extend from the top of the first of the second apron columns to the top of the first apron column, and so on. In this regard, the term "top" is used with the bridge in its form originally assembled for launch and not in its final position ready for use.
    Although all the supports 20, 30 of the figures are shown as being of approximately the same level, it is understood that the system will work just as well when the supports are at different levels.
    Although cables have been described as passing over or as being connected to the ends of columns, it is understood that they could also pass through or be connected to the columns at other points along their lengths.
    Each deck section may include a ladder having a length in the range of 2 to 8 meters. When each deck deck section includes a series of subsections, each sub-section may have a length in the range of 1.2 to 2 meters (+/- 0.3 meters). In this respect, the term "scale" refers to an ordinary scale, commonly available, having two amounts and a number of steps.
    It is envisaged that deck posts could be connected to the deck deck at points other than those where the adjacent sections meet.
    The deck columns may have a rectangular shape formed of two lateral members each extending from a deck deck spar, so that the total width of the columns is the same as that of the deck deck. The side members can be connected together with flexible but non-extensible cables, or by stiff / stiff rods and the like.
    All the cables described with reference to the figures may be replaced by other flexible but substantially non-extensible elements, such as ropes, chains and wires, or by axially rigid elements such as rods, tubes, ladders, lattices and the like.
    It is envisaged that the bridge system may be supported against an object such as a building and used to move materials up the system. The location of the attachment of any deck column to the deck may be at the center of the deck width between the two long sides, on a long side or at a point between the center and a long side.
    The apron can be equipped with apron elements for the circulation of pedestrians or vehicles. The apron elements may include half-width trays, staggered between alternate rungs, if any. They may comprise lightweight composite or alloy boards extending between the positions of the main columns, with an intermediate support from individual bridge pieces and spars.
