<正>根据我国伐区作业条件和我国人体抽样统计数据,运用人机工程学原理,对国际标准“ISO 8334-1985(E)林业机械-便携链锯-平衡测定”进行了验证,证明符合我国国情,可以等效采用。对该标准中未作规定的高把油锯,从生物力学的角度进行了探讨,结论是高把油锯纵向不平衡度不得大于7°。

Baced on the practical conditions of logging operations in China, the sampled data for Chinese human body and the principle of ergonomics, the international standard "ISO-8334-1985 Forestry Machinery-ortable Chain-saws-etermination of Balance" has been proven to be suited to China’s conditions. It can, therefore be equivalently applied in China. In addition, the paper has probed into the method of balance determination for the portable chain-saws with high handle, which has not been standardized in "ISO-8334-1985" and this paper puts foward that the angle requirement for the longitudinal balance of the portable chain-saws with high handle should not exceed 7?
