This is a short video clip of how Brandon and I lower large tree material. This is just one of several techniques that we utilize to get material safely to the ground. We have a “bare bones” philosophy when it comes to rigging: use only what is necessary and do not over-complicate the process; more moving parts could actually make the action more dangerous. There are three components to rigging that you will notice in the video: a very strong rigging/lowering rope, a lowering block up in the tree (a neighboring bifurcated trunk next to Brandon’s bucket), and a friction device (the metal object my rope travels through) anchored to the base of a tree near me. Basically, Brandon ties the log off at the top with a running Bowline. I wrap the rope around the bollard (a large metal tube) of the friction device. The number of wraps that I use is dependent upon the estimated weight of the piece we are lowering, and the amount of control that I want. More wraps equals more friction, and thusly, more control. As I make wraps, all slack is taken out of the line; I make the rope as tight as possible, to avoid any sudden drops by the log after it is released from the tree. Brandon determines the length of the log and makes his cut. In this case the rigging point and block is located above the material being removed; very little momentum is built up as the log is released from its perch. Notice how I am able to completely control the rate of descent. The friction device makes this possible. I am actually using one hand to lower that large log while I recorded the video with my phone. It is not best practice and something I do not make a habit of, for the record.
Notice all of the obstacles surrounding the tree we are removing: the house, the dog run, the tall fencing and shrubbery. We were able to entirely remove this large, double leader Oak with no damage to any of those things. We work really hard to protect the property of our clients. We treat these things as our own. Occasionally we damage some shrubbery or neighboring tree limbs, and even turf. But employing techniques like this enables us to preserve and protect surrounding obstacles, while completing some very dangerous work. It is very gratifying and impressive, if I do say so myself 😀.
