Effects of low temperature on operation efficiency of tree-felling by chainsaw in North China

Abstract

Comparison method and video-tape recorders were used in case study for recording the operation performances of two group operator. The time span was 7 months, from September to March. The performance of operations in September was taken as references. The results of test survey and data analysis showed that the tree-felling operation efficiency was influenced by cold weather, properly decreased 18.5% in average.
