【摘要】 <正> 原条拖集是国内外主要的集材方式,如拖拉机集材、绞盘机钢索集材均以拖集为主。原条拖集阻力则是确定原条拖集机械与设备的主要的工艺性参数。为了获得适合于我国东北林区原条拖集的这一参数,我们曾在东北林学院凉水实验林场进行了现场测定更多还原

【Abstract】 A description of test condions and meausring method of main skidding resistance of tree-length is introduced in detail. On the base of analysis and study of measuremeut data author has found out the relationship and function betwen resistance and lead volume of tree-lengths, and found out average and maximun skidding resistance. This paper provides a technological parameter necessary for determination the pull of skidding or yarding machines.更多还原
