Switching devices annular track 355, at a portion common to paths P1 and P2, and close to the point at which paths P1 and P2 separate. - In the
Figure 4 example, eachdrive unit straight branches 357 parallel and close to atrack 356; and acurved branch 358 parallel toannular track 355 and connectingstraight branches 357. - One
straight branch 357 ofdrive unit 352 is parallel to returnportion 16, and two straight branches are parallel to and close torespective forward portions - Drive
units unit 352, from which they differ solely by being offset 120° in theFigure 4 example. - The present invention is obviously not limited to, and includes various variations of, the embodiments described. For example, the turnaround stations may be more than three in number; the cam follower assemblies may be grip-roller types; and the cams may simply be bars gripped by the cam follower assembly rollers.
- Nor is the present invention limited to the applications described, and also applies to mono-, two-, three-, four-rope systems, etc.
- The drive unit described includes both the type comprising a number of mechanically connected wheels, and the type featuring a linear motor divided between the station and the transportation units.
- The ropeway systems may also operate with any type of switching device other than those described.
