Ziplines are cool.
Even cooler would be a zipline that allows me to go out
and back, e.g. across a river or between treehouses.
This idea is for a mechanism to allow 2-way (but not
simultaneous) traffic on a zipline. The line is fixed at
one
station, and at the other station there are
two heights at
which the line can be fixed. One is higher than station
1,
the other is lower. There is a remotely-actuatable trip
mechanism on station 2 that allows the line to fall from
the high state to the low one.
Considered the idea of a (human-)powered trolley but
this
way seems a bit simpler.

A reliable movable attach point is going to be
expensive because there is so much tension. |

I guess this idea does potentially have some
advantage over just installing two cables because
two cables would put twice the load on the support
structure and require twice as much cable. |

I love the idea of this for trams between buildings in a city. |

The problem is that for any decent span, the catenary curve will be severe enough that you need a decent height change to make sure you don't end up stuck in the middle. |

I didn't think of two tracks. Nice. |

Have both ends move with the same basic mechanism. |

The idea of having two zip lines going either direction is great, but seems like somebody would have though of that before. You zipline across the gorge, take pictures etc, then climb up the stairs to the return zipline and go back. Just requires a detachable rolling unit but that's no big deal. |

Much simpler to just make a zipline where both ends are higher than the other. |
