发明名称 Portable winch
摘要 The winch is driven by a chain saw motor through a compact and light weight chain and sprocket transmission. The transmission includes a jaw type clutch and the winch drum is provided with a hand brake. The winch drum is specially designed to facilitate the even spooling of a nylon line. A retractable dog engages a support for the winch to anchor the device against the tension exerted on the line.
