Definitions

  • This invention pertains to elevated cableway systems used in mass transit systems and the like, and, more particularly, to an improved cableway for such systems.
  • FIG. 1 illustrates in gross an elevated cableway system 10 in which vehicle 12 travels along track cable systems 14 suspended from catenary, or support cable 16.
  • track cable systems 14 comprises locked-coil steel cables 14a-d
  • catenary cable system 16 comprises locked-coil steel cables 16a-b.
  • a plurality of pylons 18 elevate and support track cable systems 14 and catenary cable system 16 between the termini 20 of system 10.
  • Track cable systems 14 and catenary cable system 16 are preferably anchored to ground 19 to sustain horizontal cable forces and transmit them to ground 19.
  • Müller also proposed tying track cable systems 14 and catenary cable system 16 together between pylons 18 at points 22 as shown in Figure 4.
  • Müller tied the cables with force equalization plate 24, in cooperation with clamping plate 26 and wedges 28.
  • Force equalization plate 24 also improved the distribution of load stresses in the cableway system and, in combination with tensioning track cable systems 14, substantially advanced the art.
  • United States Pat. No. 4,264,996 by Baltensperger and Pfister describes a suspended railway system with towers that support a catenary cable atop the towers and support track cables with a "stressing beam" that is pivotally connected to the towers.
  • the '996 system is, however, distinguishably less capable than the present invention.
  • the '996 patent fails to grasp the catenary cable at the support on top of the tower. Therefore, as described in the '996 patent, the cable is allowed to slip in the notches of the support. This slippage will inevitably cause wear on the cables.
  • the stressing beam gives some measure of weight redistribution at the track cable support
  • the fact that there is only one beam and the fact that the beam merely pivots about a single point ensures that the impact with the support of a vehicle passing over the support will not be substantially lessened.
  • the other end of the beam necessarily must tilt upwardly thereby creating a ramp for a vehicle traversing the track to climb.
  • the tilt of the beam cannot be lessened until the vehicle passes each point along the beam.
  • the beam had secondary and tertiary beams connected to it as the present invention does, the moment about the central pivot point could be lessened in advance of the vehicle.
  • the point of applied load is the point where the secondary beam attaches to the main beam, not the point the vehicle is passing.
  • This invention provides an alternate force equalizing assembly that reduces wear on the catenary cable system and the track cable systems by allowing the cables to controllably yield relative to one another as force is transferred between them.
  • an improved cableway system that includes a pylon, an upper saddle, and a lower saddle.

  • each suspension rod is pivotally connected to a cross-tie at the center of the cross-tie's longitudinal axis for rotation of the cross-tie in a second vertical plane that is perpendicular to the first vertical plane.
  • the cross-tie supports the second cable.
  • shock absorbers are each pivotally mounted at one of its ends to one of the respective tertiary beams, and the other end of each shock absorber is pivotally connected to a cross-tie near another end of a suspension rod that is connected substantially at the other end of the tertiary beam to which the one end of the shock absorber is connected.
  • bracing rods are each pivotally mounted at one of its ends to a cross-tie near a lower end of a first suspension rod. Another end of each bracing rod is pivotally connected to a cross-tie at a lower end of and near a second suspension rod that is connected to an opposite end of a tertiary beam from which the first suspension rod hangs.
  • the improved cableway system also includes improved hangers and cross-ties comprising a hanger member suspended from the catenary cable system by one end thereof.
  • a cross-tie is pivotably mounted to the hanger member at the end distal to the catenary cable system.
  • a track cable guide is affixed to the cross-tie, and a power rail guide is mounted to the cross-tie.
  • force equalizing assembly for joining the catenary cable system to the track cable systems midway between the pylons is provided to equalize the tension between the support and track cable systems.
  • the assembly includes a force equalization plate having at least three parallel channels formed along the length of a surface thereof is provided for accepting the support cable in the center channel and the track cable systems in the outer channels.
  • the channels are shaped to approximate one-half of the respective cable circumferences, except that the ends of the channels are flared outwardly.
  • the channeled clamping plate has at least three parallel channels formed along the length of a first surface thereof is provided for accepting the support cable in the center channel and the track cable systems in the outer channels.
  • the channels of the clamping plate are shaped to approximate one-half of the respective cable circumferences, except that the ends of the channels are flared outwardly.
  • the channeled clamping plate has a second surface opposite the first surface that is adapted for engagement by the wheels of the cable car.
  • the channeled surfaces of the force equalization plate and the clamping plate are complementary such that the plates may be assembled about the cables for frictionally locking the cables within the respective channels to equalize the tension in the support and track cable systems.
  • the respective flared ends of the channels in the assembled plates form a frusto-conical cavity in each end of the assembly about each of the cables for reducing wear on the cables by the ends of the plates.
  • the cables of the catenary cable system and the track cable systems are grasped about their circumferences by cable connections of a system of cable encasing members.
  • the cables are thereby connected through the cable connections to a frame of the system of cable encasing members for distributing forces among the cable systems.
  • the force equalizing assembly is adapted to accept connection of cables both from angles acute to and parallel with the longitudinal axis of the frame.
  • a catenary cable system clamp grasps the catenary cable system and a plurality of track cable system clamps grasp the pair of track cable systems.
  • the track cable system clamps are yieldably attached to the catenary cable system clamp to provided controlled force distribution between the cable systems.
  • the top surface of the plurality of track cable system clamps is adapted for engagement by the wheels of a vehicle traversing the elevated cableway system.
  • Figure 6 illustrates one of pylons 17 in a preferred embodiment of the elevated cableway system, including upper saddle 30 from which catenary cable system 16 is strung, lower saddle 200 from which track cable systems 14 are strung, and base pylon 21 on which lower saddle 200 is mounted.
  • Hangers 27 suspend track cable systems 14 from catenary cable system 16 and pre-tension track cable systems 14, as described above.
  • Pylon 17 is attached to ground 19 by any suitable technique known to the art.
  • the precise dimensions of pylon 17 such as height and width will be matters of engineering design predicated on well known structural principles to account for structural loads, such as vehicle and cable weight, and for loads arising from environmental conditions such as wind, seismic activity, precipitation and temperature.
  • Upper saddle 30 shown in greater detail in Figures 7A-C, permits relatively free motion at the top of pylon 17, and transmits vertical loads from vehicle 12 and pre-tensioning forces to pylon 17. Upper saddle 30 lessens fatigue of catenary cable system 16, requires only limited maintenance, and eases implementation of a desired 7° deviation of pylon 17. Upper saddle 30 comprises upright 32 pivotably mounted to base 34 and is capped by coupling 40, which is engaged with cable connector 42.
  • FIG. 7B coupling 40, cable connector 42, and pin 44 atop upper saddle 30 are shown in an enlarged, partially cutaway view.
  • Supports 50 help bear and distribute the load on coupling 40 to upright 32.
  • Cover 52 provides some protection for coupling 40 and connector 42 from the elements.
  • the socketing and pinned connection of coupling 40 engaged with cable connector 42 reduces the risk of fatigue to catenary cable system 16 caused by the shifting of catenary cable system 16 across pylon 18 of the system in the Müller '765 patent.
  • the embodiment of Figures 7A-C thereby reduces the risk of fatigue failure in catenary cable system 16 by precluding bending fatigue stresses, thus leaving only tension-tension fatigue stress on catenary cable system 16. This connection also permits shorter cable lengths to facilitate transportation, handling and construction of the system.
  • Coupling 40 in the preferred embodiment is a welded plate assembly including base plate 46 and at least two member plates 48 extending substantially perpendicularly from base plate 46 as shown in Figure 7B.
  • Cable connector 42 is socketed on one end to engage coupling 40.
  • Pin 44 joins cable connector 42 to coupling 40 through co-aligned holes in tines 43 of forked connector 42 and coupling 40 when cable connector 42 and coupling 40 are engaged.
  • the socket and pin connection provided by cable connector 42 must be strong enough to sustain the load on catenary cable system 16 and the loads from environmental conditions. Cables 16a-b are strung in a first direction from the non-connected end of cable connector 42.
  • Coupling 40 is also joined to a second cable connector 42 that provides cable connection to cables 16a-b in a second direction, as shown in Figure 7B.
  • Cables 16a-b are preferably clamped together as shown in Figure 7E at predetermined intervals using clamps 49 between cable connector 42 and the first one of hangers 27.
  • Clamps 49 are better illustrated in Figures 7F-G and comprise pins 51 joining clamp members 53a-d.
  • Clamp members 53a-d define passages 55a-b through which cable members 16a-b pass.
  • Passages 55a-b may include flared openings on one or both ends thereof as are discussed in connection with catenary cable clamp 85 and equalizing lock 300.
  • the flared openings of passages 55a-b are best shown in Figure 10C, wherein the lesser diameter at point 57 of passages 55a-b forms the throat of the opening and the greater diameter at point 59 forms the flare. These flared openings minimize the "beam effect" wherein a clamped cable behaves structurally as a beam.
  • upright 32 is pivotably mounted to double V-shaped base 34.
  • Base 34 like coupling 40, in the preferred embodiment is a welded plate assembly and comprises bottom plate 54 and side plates 56.
  • Side plates 56 are attached in slotted channels at each end of bottom plate 54, as shown in Figure 7C to define slots into which tongues 58 extend from the bottom of upright 32.
  • Pins 60 preferably constructed from brass to reduce friction, run through co-aligned holes in side plates 56 and tongues 58.
  • Upright 32 supports forces received through coupling 40 and transmits them to pins 60 about which upright 32 rotates.
  • Base 34 also includes additional means for bearing the load of upright 32.
  • Each of these means includes a bearing pin 62 extending through a split flanged sleeve 64 and 66.
  • Flanged sleeves 64 extend from tongues 58, and flanged sleeves 66 are welded to the interior surfaces of paired side plates 56.
  • Bearing pin 62 is held in place by threaded nuts about pin 62 both above and below sleeve 64, and reciprocates in sleeve 66.
  • the design of upper saddle 30 described above essentially implements a "pulley". Pins 60 are the center of rotation for this "pulley" and the length of upright 32 defines its radius.
  • the "pulley" diameter may be variable and, in the preferred embodiment, is 150 times the diameter of catenary cable system 16.
  • lower saddle 200 is designed to accommodate deflection of upright 32, and transmit the vertical and lateral loads applied across a portion of track cable systems 14 to pylon 17, which ultimately transmits the loads to the ground. In this manner, the lower saddle transmits loads developed by vehicle 12, cables 14, the environmental conditions, and deviation of upper saddle 30 (up to 7 degrees each direction). Furthermore, lower saddle 200 provides for a smoother transition from one pylon span to another than previously available, and increases the comfort of the vehicle's passengers by reducing the curvature of track cable systems 14.
  • Lower saddle 200 is connected to pylon base 21 beneath pylon upright 32 by way of transverse pylon beam 202, that is mounted transversely to and extends outwardly from either side of base pylon 21. This connection between the lower saddle and pylon base 21 is also illustrated in Figure 6.
  • transverse connecting frame 204 is connected to one end of transverse pylon beam 202 and extends downwardly therefrom to accept and transmit lateral and vertical forces to pylon 17.
  • a second identical transverse connecting frame extends downwardly from the other end of transverse pylon beam 202, providing a second guideway on the other side of each pylon, but only one such frame 204 will be discussed herein to avoid redundancy.
  • transverse connecting frame 204 includes two vertical suspension beams 206A, 206B connected to transverse pylon beam 202 and extending downwardly therefrom. Suspension beams 206A and 206B are connected by horizontally positioned transverse beam 208 by way of bolted connections 208A.
  • Webs 210 are welded to and extend vertically across transverse support beam 208 for added stability.
  • Bearing plates 212A and 212B are welded to and extend upwardly from transverse support beam 208. The assembly of the horizontal and vertical beams, and other associated hardware thus forms the structural skeleton of transverse connecting frame 204.
  • FIG. 7Y and 7Z An alternate means of connecting a lower saddle to a base pylon beam 201, functionally similar to support beam 208 described above, is illustrated in Figures 7Y and 7Z.
  • At least one pair of connecting plates 203 is attached to the base pylon beam to substantially encase the base pylon beam.
  • Cap plate 207 is connected to the top of connecting plates 203.
  • An upper attachment plate 209 is removably connected to cap plate 207 by a plurality of bolts.
  • the attachment plate is fixed to bearing plates 212A and 212B in a manner similar to the attachment of bearing plates 212A and 212B to the transverse support beam described above.
  • a hanger plate 211 is connected to the bottom of connecting plates 203. The hanger plate is fitted with holes to accept bolts to removably connect additional structure as described below.
  • a vertical load transmission system is pivotally connected to transverse connecting frame 204, shown in Figure 7M, or alternatively to base pylon beam 201, shown in Figure 7Y, for transmitting vertical loads developed by the vehicle and cables, as well as those loads developed by deflection of the upper saddle, to base pylon 21.
  • a primary requirement of the vertical load transmission system is that vertical loads transmitted by the system should be well distributed over a portion of the track cable systems to avoid damaging curvilinear deflections in the cables.
  • the vertical load transmission system is preferably an isostatic system of interconnected beams and bars arranged in a hierarchical manner.
  • main beam 214 is a welded plate assembly formed in rectangular cross-section, and is pivotally mounted through its side walls at the center of its longitudinal axis to bearing plates 212A and 212B for rotation in a vertical plane.
  • Main beam 214 is bi-symmetrical and has a variable height defined by a sloped upper surface that peaks at its center directly above its pivotal mounting point and slopes downwardly towards its ends 214E.
  • Lower surface 214L of the main beam is flat and extends horizontally between ends 214E.
  • Dumbbell-shaped collar 216 is mounted at its disc-like ends 216A and 216B across the sides of the main beam in circular openings 218A and 218B, respectively, as shown in Figures 7N.
  • Shaft 220 is mounted through the longitudinal axis of collar 216 and extends out of ends 216A, 216B through cylindrical openings 220A and 220B therein, respectively.
  • the ends of shaft 220 further extend through openings 222 and associated radial bearings 222A in bearing plates 212A and 212B of the transverse connecting frame, as indicated in Figures 7H and 7N, thereby supporting the main beam for rotation relative to the pylon.
  • Bearings 222A are bronze to reduce friction.
  • a pair of secondary beams 224 are pivotally mounted at the centers of their respective longitudinal axes to flanges 226 connected to and extending downwardly from locations near the respective ends 214E of the main beam, enabling rotation of the secondary beams relative to the main beam in the same vertical plane that the main beam is rotatable within.
  • Flanges 226 are equipped with openings 232A and 232B, respectively, for mounting shafts 234 therein, as displayed in Figures 7L and 7Q.
  • Shafts 234 pass through discs 236A and 236B mounted within circular openings in respective secondary beams 224, pivotally connecting the secondary beams to flanges 226 near each end of the main beam. Rings 230 retain shafts 234 in place.
  • the secondary beams are formed of a welded plate assembly that results in a variable height and a rectangular cross-section.
  • tertiary beams 238 are each pivotally mounted at the center of its longitudinal axis to one of respective secondary beams 224 substantially at a respective end of the secondary beam for rotation in the same vertical plane that the main and secondary beams are rotatable within.
  • tertiary beams 238 carry collars 240 in circular openings 240A. These collars are aligned with two respective sets of complementary discs 242A and 242B, one set of discs 242A, 242B being mounted in circular openings near each end of secondary beams 224.
  • Shafts 244 extend through aligned openings in the respective disc-collar-disc assembly 242A, 240, and 242B to pivotally connect the centers of tertiary beams 238 to the respective ends of secondary beams 224 in a conventional manner.
  • the end portions of the upper and lower faces of secondary beams 224 are cut open somewhat to permit unimpeded movement of tertiary beams 238.
  • Eight suspension rods 246 are each pivotally mounted at their upper ends to each of respective ends 238E of the tertiary beams for rotation in the vertical plane.
  • Bolts 248 pass through circular openings in each of the suspension rod halves 246A, 246B as well as a circular opening in each of the ends of tertiary beams 238.
  • Cylindrical bearings 250 are positioned about bolt 248 to facilitate relative rotation between the suspension rods and the tertiary beams, and to maintain the spacing between the suspension rod halves. Similar bearings are provided at other interfaces where components rotate relative to one another throughout the lower saddle, in conventional fashion.
  • each suspension rod 246 is pivotally connected to a cross-tie 256 by way of flange 258 that extends upwardly from connecting plate 259.
  • Cross-ties 256 function to transmit vertical and lateral vehicle loads to the vertical and lateral load transmission systems, via the engagement of the vehicle wheels with the rails carried by the cross-ties.
  • Connecting plate 259 is bolted via four bolts 259A about the intersection of the cross-tie's longitudinal axis with the axis of an equalizing beam (described below), enabling rotation of cross-ties 256 in the vertical plane relative to the suspension rods.
  • bolts 259A actually consist of four sets of bolts of varying lengths to accommodate the differing thicknesses of the equalizing beam across lower saddle 200.
  • Bolts 252 pass through circular openings at the bottom of suspension rod halves 246A, 246B and openings through flanges 258.
  • the suspension rod halves are connected with welded web 257 that effectively provides an I-section to minimize the risk of instability in the suspension rods.
  • Cylindrical bearings 254 again facilitate relative rotation and maintain the spacing between the suspension rod halves.
  • Rod halves 246A, 246B are enlarged at each of their ends for the pivotal connections to the tertiary beams and the cross-ties, respectively, as shown in Figure 7R. This rotation of the suspension rods at both ends prevents the rods from taking any moment due to lateral forces which, as explained below, are devoted to the equalizing beam.
  • bracing rod pairs 247 and shock absorbers 249 are added to alternate tertiary beams 239 and suspension rods 246 to further dampen the impact of vertical loads applied to the track cable systems by dampening the rate at which the suspension rods and the tertiary beams rotate relative to one another.
  • the figures disclose an embodiment wherein the secondary and tertiary beams have hanger plates being used to connect lower members to higher members. Secondary hanger plate 229 is shown suspended from alternate secondary beam 225 to support alternate tertiary beam 239. Tertiary hanger plates 241 are shown suspended from alternate tertiary beam 239 to support suspension rods 246. Additionally, sets of suspension rods 246 are used rather than single suspension rods 246 at each end of each tertiary beam.
  • Bracing rod pairs 247 have holes at either end through which bolts 253 pass, thereby pivotally connecting the bracing rods to the rest of the assembly.
  • the end of shock absorber 249 adjacent to the lower end of the suspension rods is also pinned by bolt 253 to pivotally connect the shock absorber to the suspension rods 246, bracing rod pair 247, and alternate cross-ties 255.
  • the alternate cross-ties are substantially similar to cross-ties 256 described below, but have two flanges 258 rather than one, as shown in Figure 7T. The additional flange enables attachment of a shock absorber between the flanges, as seen in Figure 7Z.
  • the opposite end of the shock absorber i.e.
  • bracing rod pairs 247 and shock absorbers 249 could be appended to the first disclosed beam and hanger arrangement.
  • Cross-ties 256 are different from cross-ties 25 on the pylon spans, which are described below. Cross-ties 256 transmit an upward vertical force to the track cable systems to support them at intermediate points between pylons. Cross-ties 25 transmit an upward vertical force to the track cable systems to support them from the lower saddle 200.
  • cross-ties 256 include flat plates 257 to which grooved blocks 257A are welded to serve as a bearing for track cable systems 14.
  • a rail is provided in the form of a second grooved block R that is used to clamp the carrier cables to cross-ties 256. Three rows of bolts are used to secure grooved blocks R to flat plate 257, as shown in Figure 7W.
  • Interim cable track support sections 257A' are provided between cross-ties 256 and are connected to grooved blocks 257A to form a continuous bearing cradle for track cable systems 14.
  • Grooved blocks R are butterfly shaped, as viewed in Figure 7I, resulting from symmetrical grooves cut into each end.
  • Lower saddle 200 further includes a lateral load transmission system that contains equalizing beam 260 carried across the cross-ties 256, and lateral support stud 282 carried by transverse connecting frame 204, as shown in Figures 7H and 7V.
  • equalizing beam 260 spans transversely across the lower saddle's cross-ties 256 to transmit lateral forces to lateral support stud 282.
  • the equalizing beam further serves to stabilize suspension rods 246 in the face of lateral forces.
  • the equalizing beam must be flexible in the vertical direction so that the vertical load transmission system operates effectively as an isostatic system, but also must be reasonably stiff in the lateral direction to transmit lateral forces.
  • equalizing beam 260 includes superimposed plates 264, 266, 268, and 270 of different lengths and thicknesses, as displayed in Figures 7V and 7W.
  • plate 264 is shorter than plate 266, which is shorter than plate 268, and so forth.
  • the widths of the plates are greatest at the center of their longitudinal axes and decrease along the lengths of the plates towards each of their ends. This variable width, plus the variable thickness of the super-imposed plate stack, decreases the lateral and vertical moments of inertia of the equalizing beam at its end where bending strength is least needed.
  • cross-ties 256 Lateral and vertical loads are transmitted at cross-ties 256 by four bolts 259A that connect the cross-ties to both the vertical and lateral load transmission systems, which operate independently from one another.
  • cross-ties 256 are connected to suspension rods 246 and equalizing beam 260 using bolts 259A.
  • the bolts are fixed in threaded holes 259B in the cross-ties for better transmission of lateral forces than if secured with nuts.
  • the plates of equalizing beam 260 are joined together near their centers by bolting the plates together along with the center-most cross-ties 256 and suspension rods 246 using bolts 259A, as displayed in the left-most equalizing beam 256 of Figure 7W.
  • the plates of the equalizing beam should otherwise, i.e., outside of the center, be free to move longitudinally. This freedom of movement is realized by using a teflon coating between the plates that provides for maximum vertical flexibility, and by making the bolt holes in the plates that are aligned with the other cross-ties slotted in the longitudinal direction.
  • Bolt sleeves 259B are provided in these slotted bolt holes that are slightly taller than the equalizing beam's plate stack to avoid clamping the plates outside of their centers, as shown in the lower portion of Figure 7R. This allows vertical loads that are transmitted from cross-ties 256 to suspension rods 246 to effectively bypass equalizing beam 260.
  • the lateral load transmission system is further connected to transverse connecting frame 204 and extends downwardly therefrom in the form of lateral support stud 282 to provide for lateral rigidity of the track cable systems and to sustain loads due to environmental conditions.
  • Lateral support housing 276 is connected to and extends downwardly beneath transverse support beam 208.
  • Lateral support stud 282 is encased within housing 276 and extends downwardly through the center thereof.
  • the lower portion of steel lateral support stud 282 is tapered and extends downwardly through respective aligned grooves 286 formed through clamping plates 262 as well as each of the plates of the equalizing beam, as shown in Figures 7J and 7K.
  • External contact faces of the stud are chromium plated, and are capped with plates 282A made of a hardened steel material, e.g., quenched and tempered steel.
  • Clamping plates 262 are provided with guide blocks 284 for engaging lateral support stud plates 282A and limiting the motion of stud 282 within groove 286 to linear motion along the axis of the equalizing beam.
  • Guide blocks 284 are also made of a hardened steel material in order to sustain the high contact pressure at the lateral support stud plates.

As is shown in Figures 2 and 4, both long and short hangers are used depending on the hanger's distance from pylon 17 and span midpoint 22. In addition to differing lengths, hangers 27a-b differ in that hanger member 91 of hanger 27a is a locked-coil steel cable but in hanger 27b is a rod. Furthermore, short hanger 27b can be used in different lengths using the same construction. Two different lengths are used for short hanger 27b in a single 600m span in the preferred embodiment.
  • the length of hangers 27a-b is calculated to pre-tension track cable systems 14 as described above, to transmit vertical, pre-tensioning forces to pylon 17, and to ensure clearance between catenary cable clamp 85 and vehicle 12 in high winds, and so the length thereof will depend on the particular application for a given embodiment.

  • the length of the threads on threaded end 68 must consequently be sufficient to accommodate the desirable range of tensions. In long hanger 27a, this will nominally be a 0-300mm and in short hanger 27B the length will vary but be at least greater than 50mm.
  • Suspension clamp 85 is pivotably mounted to hanger member 91 at pivot 76.
  • Suspension clamp 85 comprises first guide member 86 bolted to lower guide member 88 as shown in Figures 9A-B.
  • Suspension clamp 85 includes passage 106 through which threaded end 68 of hanger member 91 extends, and block 78 joined to first guide member 86 at pivot 76 such that catenary cable system 16 and suspension clamp 85 may pivot relative to hanger member 91 16° relative to the horizontal normal as shown in Figure 9D.

  • Hanger member 91 as shown in Figures 8A-B, of long hanger 27a is jointed and includes upper piece 92, essentially a threaded fork member, and lower piece 94, a steel cable, moving relative to one another at joint 96; hanger member 91 of short hanger 27b is not jointed.

  • Cross-tie 25 is preferably constructed from cast steel and is I-shaped in cross-section as shown in the isometric view of Figure 8A and in the cross-sectional view of Figure 10B.

  • Rails 100 constructed of aluminum comprise modular segments that typically are sufficiently large to span the entire distance between hangers 27. Although one end of each segment will be relatively fixed in position by the mating of bolts 114 to slot 120 as discussed above, the other end will be softly, rather than rigidly, fixed by the mating of grooves 122 with cables 14a-d. The movement thereby permitted accommodates thermal expansion of the segments and is therefor desirable. Thus, thermal expansion joints 127 are created between rail segments such as joint 127 between segments 129 shown in Figures 8A, and 10A-B. Joints 127 are preferably angled at 45° relative to the longitudinal axis of rails 100. Rails 100 also include upper surfaces 132 and sides 134 providing a smooth and gliding surface for vehicle 12 in the preferred embodiment as discussed below. Although not shown, the preferred embodiment includes a layer of insulation between rails 100 and cables 14a-d to avoid corrosion and reduce noise.
  • rails 100 Other modifications may be employed in the design of rails 100. For instance, holes 124 are milled into individual segments of rails 100 to decrease weight and the heads of bolts 114 need not be of uniform height above cross-tie 25 if it is desirable to incline segments of rails 100. One may furthermore provide some means for heating rails 100 for use in particularly cold climates. These and other such modifications are contemplated by and are within the scope of the invention.
  • Power rail 90 may be mounted to cross-tie 25 as shown in ghosted lines in Figures 8B and 10B. Power rail 90 is grasped by power rail guide 84 bolted to plate 112, which in turn is bolted to the bottom of cross-tie 25. As shown in Figure 8B, a power rail 90 and power rail guide 84 are preferably mounted to each end of cross-tie 25 in this embodiment. Also as is known in the art, power rail 90 must be electrically insulated from all other parts of the system for safety reasons.

  • Force equalizing assembly 300 substantially prevents relative movement between catenary cable system 16 and track cable systems 14 and distributes forces therebetween through friction on the cables. As such, the force equalizing assembly reduces the maximum deflection of the guideway by impeding relative movement between the cables.
  • Force equalizing assembly 300 includes force equalization plate 302 having three sets of parallel channels formed along the length of the upper surface thereof for accepting catenary cable system 16 in the center two channels 302B and track cable systems 14 in the outer four channels 302A.

  • the respective flared ends of the channels in the assembled plates form a frusto-conical cavity in each end of the assembly about each of the cables for reducing wear on the cables by limiting engagement, and therefore bending stresses, with the ends of the plates, a feature lacking in the Müller disclosure.
  • the flared ends are defined by narrower diameter 307 and greater diameter 309 in the opening of the channel through the assembly as best shown in Figure 11D.

  • Bolts 306 are retained by respective nuts 310. Flush mounting of the bolts prevents the possibility of the vehicle wheels colliding with one of them.
  • Clamping plate 304 may have an upper surface that is elevated at its center (not shown) above the two center channels 304B to provide a greater cross-sectional area at the areas of greatest stress.
  • the upper surfaces of plate 304 are further adapted for engagement by the wheels of the cable car.
  • the force equalizing assembly interfaces with the rail profile to assure a continuous running track.
  • the rail profile must therefore accommodate the profile, i.e., shape of equalizing lock 300. It follows that the 45° expansion gap in the rail cannot be used at the rail's engagement with the force equalizing assembly.

  • Frame 333 is made up of base frame 336 which is an elongated plate with U-shaped ends 338.
  • U-shaped ends 338 of the embodiment shown consist of legs 340 and 342 which are of different lengths. Because legs 340 and 342 are of different lengths, clearance is created between the connections to allow for less moment stress development at the base of the "U" for a given tensile load on the cables. That is, if the legs were not of different lengths, the connections would be side by side. In order for the side by side connections not to interfere with one another, legs 340 and 342 would have to be farther apart. Because the legs would be farther apart, a greater moment would be created near their respective connections to the rest of the frame. The different length legs avoid this condition.
  • a plurality of askew connection plates 344 extend from the vertical faces of base frame 336 at acute angles to the longitudinal axis of the base frame and provide points of connection for track cable systems 14.

  • Bracing bars 352 extend perpendicularly from cross members 346 to provide lateral support for the cross members.
  • Wheel support rails 350 span between cross members 346 and may have spacer plates 348 between the rails and the cross members to give additional elevation to the rails. Wheel support rails 350 typically do not have track cables running underneath them. However, wheel support rails near the transition points where the track cables must pass underneath and into the support rails must be altered to avoid interfering with the track cables. Thus, transition wheel support rails 354 have channels cut in their lower faces and sides to allow passage of the cable of the track cable systems 14 through the sides of the wheel support rails.

  • Figure 11H shows arrangements of track reaction plates 388 and track springs 390.
  • the means for accomplishing controlled relative movement among clamps is to place springs between the clamps and the cross extensions of the assembly body. By using springs with different spring constants, different amounts of resistance can be generated between selected clamps. By placing springs with lower spring constants closest to the end of the cable to which load is applied, these clamps will be allowed to deflect more under a given load. Since the clamps on the closest end are allowed to deflect more, more load is passed on to the farther clamps. By this mechanism the clamping pressures required by the respective clamps are equalized.
  • a basic problem with clamping cables is that large stresses tend to be generated near the point where a cable exits a clamp. Furthermore, the stress is accentuated if the cable is subjected to lateral loadings that additionally strain the cable at the exit point due to bending induced by the lateral loading. In this arrangement, as illustrated in Figures 11F and 11L, an extension member guide 400 is added to the force equalizing assembly to address this problem.
  • Extension member guide 400 is bolted to assembly body 367 at the entry and exit ends of catenary cable system 16. Extension member guide 400 guides catenary cable system 16 into catenary cable system clamp 370 to reduce the wear on catenary cable system 16 due to combined tension and bending of catenary cable system 16 at the point of entry into catenary cable system clamp 370.

  • extension member guide 400 The holes formed for catenary cable system 16 through extension member guide 400 are slightly larger than the cables of catenary cable system 16. The purpose of the enlarged holes is to provide for limited clamping of catenary cable system 16 without generating the unwanted stress at the outer ends of the clamp. Extension member guide 400 essentially guides catenary cable system 16 more squarely into catenary cable assembly clamp 370. Thereby, the more extreme stresses developed by combined tension and bending of the cable are not experienced. In a preferred arrangement of extension member guide 400, linings 406 are fitted between guide 400 and cable system 16 to provide limited clamping friction therebetween without inducing wear therebetween.
