Abstract: These years, many places in the apline forest region begin to use none power ropeway as a transporting machine at the foot of the mountain to carry the logs which are transported by the powerway from the top. It has become an economic and practical wood yeading equipment.Now, however, there have not been any theoretical method to design and calculate this kind of none power ropeway. Most of them were built by experimence. So problems often occur. Therefore, I put forward this article——"None Power Ropeway Design and Calculation Method". The followings are the points mentioned in the article:1. The maximum gliding force of the loaded pulley.2. The minimum loading of carrying empty pulley by a loaded one.3. The possible maximum speed of log gliding.4. The rational winding number of the speed controller.5. The calibration and determination of the standards for the haul line.
