Logging Methods And Techniques

Do you have logging needs?

Maybe there are a few trees that need to be cleared but you don’t know how to do it?

When the size of the tree isn’t large, logging seems like an easy task , but if today is cutting taller oak or even pine and so on, things get complicated, following the introduction of the precautions before logging in the previous article, this article will introduce the operation knowledge of actual logging in more detail.

In addition to the protective gear and clearing the road mentioned in the previous article, after deciding the direction that the tree fell, the operator needs to choose the placeholder well, the fastest location is on both side of the tree where it fell, the end where it fell, the end where the tree fell is the most dangerous, and the other side may be a situation where tree trunk debris can be sprayed. Therefore, a position 90ﾟ from the direction of the tree falling is the safest place.

Next, we will introduce the steps of logging, it’s mainly divided into three actions: making the inversion mouth, making the back mouth, and using the wedge to control the inversion.

1.Make Inversion

The pouring mouth is divided into open pouring mouth, top pouring mouth and bottom pouring mouth, the angle of the opening affects when the tree falls, the ideal state of the up and down pour is to present a 45-degree angle in the gap near the heart of the wood, and top[ pouring mouth is relatively easy way to get started and make, as for trees growing on slopes is better to cut with bottom pouring mouth, In this way, the tree body is not easy to bounce up and back, and the most difficult open pouring mouth to make, the length of time the tree has fallen, therefore, the number of seconds for the tree to fall is also the most.

 2.Make Back

The production method of the back mouth is to cut a knife in the opposite direction of the inverted mouth, and the height of the back mouth should be paid attention to. When the inverted mouth is in an open form, the horizontal position of the inverted mouth and the top corner of the inverted mouth must be at the same level. In terms of height, when the form is upside down or downside down, the horizontal position of the backside incision must be higher than the top corner of the downside down.

3.Use The Wedge To Control The Reverse Direction

When the invert and the back are finished, knock the wedge into the back. On the one hand, the incision creates a gap, and on the other hand, it adjusts the angle of the tree's inversion. The deeper the guide is, the easier it is to knock the wedge in. The shallower the guide opening, the more effort must be spent to knock in the wedge.

After finish three steps, the trees will slowly fall in the direction we set, that’s simple logging tips, and to allow reader know more details about logging, everyone can refer to the video connection: https://www.youtube.com/watch?v=mWIAPuMtIco

At last, to remind again that logging isn’t an easy task, a little more effort is needed in the field assessment and personnel safety to make the work pleasant and smooth!
