对于在主伐伐区,使用J—50进行集材作业的过程中,有时集材道的宽度是不好控制在规定的范围以内的,容易形成超宽。这从资源管理、伐区管理等方面的要求上,都是不允许的。那么产生的原因是什么呢?应该采取那些对策呢? 一、对于产生问题原因的分析 1.绞集时由于绔刮树,使得本以达到宽度标准的集材道再次加宽。 J—50在集材道上绞集原条时,当原条的一端(一般是小头)被绞上搭载板后,开始运时,无非有下列四种情况: ①原条的左、右两侧均不靠近树木,一直到所集原条的着地点全部运动到集材道上也不刮立木。 ②靠近被集原条,在J—50前进方向的后侧有一株或几株立木。 这两种情况下都不会引起树刮树,不能导致集材道超宽。
In the main cutting zone, the use of J-50 for sizing operations, and sometimes the width of the soot channel is not well controlled within the specified range, easy to form wide. This is not allowed from resource management, cutting area management requirements. Then what are the reasons for that? What should be taken? First, for the analysis of the causes of the problem 1. Twist set due to scraping the tree, making the width to achieve the standard width of the timber again widened. When the J-50 dangs the original strip on the dunnage track, when one end of the original strip (usually a small one) is hanged on the carrying plate and starts to be transported, there are no more than four cases as follows: ① The left and right sides of the original strip The side are not close to the trees, until the original set of the site of the movement all the way to the timber does not scratch wood. ② close to the original set of articles, in the J-50 forward direction of the back of one or several standing trees. In either case, it will not cause the tree to scratch the tree and it will not result in a very wide range of timber paths.
