| Research Abstract |
1. We made a control program of electronic operating system for Triangular Running Skyline (TRS), and experimented it on an actual operation. It is clear that the program is practical use and useful, and that the ratio of interlocking (recover power / winding power) is 0.4 - 0.6.
2. On a moving-cable systems, a remote control is necessary to increase a skidding productivity.
3. On falling block system, the operation is very variety and a number of operations is as more as operator's skill. It is necessary to simplify a operation of durum revolution control by a break and a clutch like a pushing button, and to have a interlocking mechanism because each wire lines is always stretched for carriage running.
4. On running skyline skidding system, the interlocking yarder is very useful and the operation is easy. But it becomes a problem, whether we choose a speed of carriage or a freedom of operation.
