Description

Details

Our strongest line-tensioning system is popular among advanced riggers for quickly and effectively creating massive pulling power on rigging lines up to 13mm. Within minutes of finding a solid and safe anchor, you’ll finish threading these sturdy Petzl blocks to produce five times the amount of tension possible without them! Made popular by ArborMaster safety trainers and search-and-rescue professionals, this type of system utilizes two Prusiks—one that holds tension between strides (after the blocks come together) while the other is adjusted longer (blocks apart) to pull again. The Petzl Twin and Minder blocks are quickly applied mid-line and without stooping to the ground with a simple procedure you can use time and time again to produce from 2:1 up to 5:1 mechanical advantage, depending on the need.

Although they’re not delivered with line as a kit, you can use your own line to create a stand-alone system much like our fiddle block system. The limitations to the tree pulling kit (as sold) are that it doesn’t work in conjunction with a lowering device (Port-a-Wrap) if host rigging line is utilized, the system requires above-average rigging knowledge, and it requires a minimum of 30 excess feet of line’s end to make use of. Once learned, this simple mechanical advantage system is hard to forget, and even harder to live without.

This is a great tool for any tree crew. I've pulled over some very large trees with this kit and you can use the pulleys for other rigging applications. (Posted on 4/15/2014)
