Abstract: The construction, the function and the bunching production technologyof the self-moving double-drum light winch are discussed. The winch canmove by itself on main skidding roods, suitable for frequently moving work.The guidable bunching production technology established in this paper is ab-vantageous to protect the reserve, the sapling and the ground surface. Thecomprehensive bunching efficiency can be increased by 64.7%, and the prod-uetion cost, reduced by 11.0%.

Key words: Double-drum winch, Bunching, Tending, Self-moving
