STUDY ON THE LOG PRODUCTION LINE IN LOG YARD

The article deals with the prduction lines in log yard by investigating the utilizationof machines in forest areas,presents the methods and rules of differentiating the log productionlines and also summarizes the formation and development of three kinds of log production lines innortbeast forest areas of China.It gives different combination types of log production lines andtheir applications, so it is significant for us to evaluate and standardize the log Production lines.

伊春林区贮木场原木生产线机械使用情况的分析

通过伊春林区贮木场原木生产线机械使用情况的调查,研究了该林区原木生产线产量级、各工序机械能力利用系数和权均利用系数,并依此对原木生产线机械利用情况进行了分析。文中又以原木生产线工序机械能力损失最小为目标,研究了该林区的7种机械组合型式和17个方案。对龙门起重机输送机组成的原木生产线(LmiS_i-Y)的各方案进行了分析比较,获得了最佳的组合方案。
