Description: An operational test of a small, prototype running skyline yarder was conducted early in 1978. Test results indicate that this yarder concept promises a low cost, high performance system for harvesting small logs where
skyline methods are indicated. Timber harvest by thinning took place on 12
uphill and 2 downhill skyline roads, and clearcut harvesting was performed on 4 uphill skyline roads. Skyline roads were spaced about 46 meters (150 feet) apart and were up to 335 meters (1,100 feet) long. Delays caused by the yarder were insignificant. Production as high as 343 logs per day was achieved.
Keywords: logging equipment engineering, production studies (-forest operations, logging operations analysis/design, logging economics
