The Importance Of Managing Friction

Friction Management


p class=”art”>The force of friction plays a major role in almost every aspect of tree care professionals’ daily work activities. All of the hitches and knots that are so vital to climbing arborists for attaching or securing themselves and other objects to lines and cordage rely on some degree of friction to stay tied in place.

Friction works to a tree crew’s advantage when carrying out rigging operations when they use the friction generated by a lowering device or tree wraps to lower wood and branches under control. Yet, a similar form of friction to the one that allows these experts to lower huge loads safely and securely can be inefficient when ascending into the tree. This would be friction present at the tie-in point (TIP).

Conventional and traditional climbing involves simply running the climbing line over a branch or around the trunk in the desired location for the TIP. The friction generated by the rope on bark/wood contact takes quite a toll on the user, the climbing line and the tree.

There are many friction-reduction devices that can be used to better manage this friction at the TIP, and also a myriad of ways that climbing arborists can create their own out of appropriately rated slings, carabiners and pulleys once they understand the advantages of reduced friction aloft.

The cambium saver is simply a sewn leather tube shaped in a curve. The climbing line passes through it, reducing the amount of friction the climber has to work against while also protecting both rope and bark from excessive wear and heat due to mutual contact.
