Hey all. Tightening up a 90' line yesterday and the steel cable snapped. :shock: (No real injuries, just a bruise.) Anyhow. I'm looking for alternative ways to tighten big lines. Thanks! :D

For long lines I recommend busting out some climbing gear, pulley's and ascenders and rigging a 4/1 pulley system, then tying off your rig and removing the system once tightened. Another way is to get the Slackline Bros tensioning system...great for longer lines (slackline.com). Best of luck

Your comealong must not be very good. Alot of people use them to pull big trees in certain directions while cutting them down to control the tree's fall.

If I want to tighten a long line, say around 90 feet or so, I use a little old fashioned hauling technology (courtesy of the aid climbing forum). I use pulleys, ascenders, slings and biners to create a compound hauling system probably in the neighborhood of 14:1 mechanical advantage :shock: (I hate having to pull any harder than necessary but rarely have someone else with that I can get to tighten my line for me). I found this picture here in the post by wigglestick (hit page down A LOT - it's a little more than halfway down). Not sure where it originally came from. Anyway, this is pretty much what I do (the 7:1 system compounded with a 2:1 system ... 7x2=14:1). That way I don't have to pull hard at all, and I can save my valuable energy for playing on the line. 8)

Hope this helps

Asana sells a slackline through Mountain Gear. It is very easy to set up and use.
