虽然固定的锯截设备在很大程度上替代了电链锯造材,作为机械化很好媒介的,具有一定特性的便携式工具,它还将长时间保持一定的作用(如建筑工程、准备作业、辅助与修理工作),单纯追求新设备替代是不适宜的。到1990年,大约30%的林区锯木工作量还将由电链锯来承担。因此,继续完善和改进电链锯是十分必要的。为使电链锯适应上述任务与辅助作业,应当在减轻链锯重量、提高锯切生产率、方便操作等方面研制新的便携式电链锯。 Although fixed sawing equipment to a large extent replaced by electric chain sawing, as a mechanized good medium, with certain characteristics of portable tools, it will remain a long time a certain role (such as construction, preparing for homework, Auxiliary and repair work), pure pursuit of new equipment alternative is not appropriate. By 1990, about 30% of the sawmilling workload in the forest area will be covered by the electric chainsaw. Therefore, continue to improve and improve the electric chainsaw is very necessary. In order to adapt the electric chain saw to the above tasks and auxiliary work, a new portable electric chain saw should be developed in terms of reducing the weight of the chain saw, improving the sawing productivity, and facilitating the operation.
