油锯是木材生产的主要工具,伐木、造材、打枝都需要它。在木材生产成本的材料费用中,油锯费用占了一定的比例。据福建省龙岩林业局一些基层单位的统计,由于生产条件、管理及技术水平的不同,油锯费用一般在每立方米0.60～0.90元之间。但是在实际上,除了锯链以外,正常磨损的油锯零部件并不多,特别是动力机方面。我们曾检查了三个国营伐木场的旧料堆,对15种油锯部件(基本是051油锯)340个零件的损坏原因作了分析,结果如下表:
Chain saws are the main tool for wood production and they are needed for logging, framing, and cutting. In the material cost of the wood production cost, the cost of the chain saw accounts for a certain proportion. According to the statistics of some grassroots units in the Longyan Forestry Bureau of Fujian Province, due to the differences in production conditions, management, and technical level, the cost of chain saws is generally between 0.60 and 0.90 yuan per cubic meter. But in fact, in addition to the saw chain, the normal wear of the chain saw parts is not much, especially the power machine. We have checked the old stockpiles at three state-owned logging sites and analyzed the causes of the damage of 340 parts of 15 chain saw parts (basically 051 chain saws). The results are as follows:
