Abstract

Abstract This study deals with a question whether the magnitude of vibrations affecting the power saw operator during the tree felling is still the same or not. For this purpose, the tree felling was broken down into several partial operations (pruning of lower tree part; cutting of buttresses; felling; delimbing) at which the values of vibrations were recorded and mutually compared. The vibrations were measured during the felling of 121 trees with the activity being made by one feller with one type of power saw and one type of power saw chain, and the felled trees included both live and dead standing trees. The vibrations were measured on the front and rear handles of the power saw in compliance with standards EN ISO 22867, EN ISO 5349-1 and EN ISO 5349–2. As to the mutual comparison, research results demonstrated a difference in 69.23% of cases. A maximum increase of vibrations during the experiment (17.0 m s–2) was recorded on the rear handle during the partial activity of Delimbing live trees, the lowest increase of vibrations (0.320 m s–2) being localized in the same partial activity, only on the front handle.

在森林砍伐过程中，影响操作员的动力锯振动幅度的差异

摘要本研究探讨了在砍伐树木过程中影响电锯操作员的振动幅度是否仍然相同的问题。为此，树木砍伐被分解为几个部分操作（修剪树木下部；切割扶壁；砍伐；分解），记录振动值并相互比较。在砍伐121棵树的过程中，测量了振动，其中一名砍伐者使用一种类型的电锯和一种型号的电锯链进行砍伐，砍伐的树木包括活的和死的立着的树木。根据EN ISO 22867、EN ISO 5349-1和EN ISO 5349-2标准，对电动锯的前后手柄进行了振动测量。关于相互比较，研究结果显示69.23%的病例存在差异。在Delimbing活树的部分活动期间，在实验期间，后手柄上记录到振动的最大增加（17.0 m s–2），振动的最低增加（0.320 m s–2中）局限于相同的部分活动，仅在前手柄上。
