I set up a zipp line for the kids in the back yard. The top is set in a Live Oak at about 30' -- and it extends over 80' down to the anchorage point. Luckily, my zipp line was 150' kernmantle,, plenty long enough for what I used it for. Then on the zipp-line I have my hitchclimber attached to a biner with a spinner and another biner attached to the harness. The harness I fashioned from a continuous loop of nylon rigging sling. Then to pull the kids to the top, I had rigged up a pulley next to the top zipp-line which I use to pull them back to the top-- and to control the descent somewhat. They freakin love it! After doing this for an hour or so, I decided to order a childrens harness from Wesspur. That way, it's a little more comfortable than the sling I created which gets tighter with weight added.
Here's a crude draft of what it looks like......
