The average slope was about 20 degree. The logging operation used both a skyline system and a high-lead system of skidding. A time study of the entire skidding operation was made. The relationship between operational features and other factors such as yarding distances, was analyzed. The times of carriage out haul and carriage in haul were influenced by the yarding distance. Especially, the time of carriage in haul was influenced by the number of delays of turns of logs. Ground-skidding is best for yarding for short distances and skyline-skidding is better for long distances because the time for setting up and dismantling the skyline takes much time. From these results, we can obtain a profitable logging operation system in thinning with the use of a truck-crane.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55248","nameIdentifierScheme":"WEKO"}],"names":[{"name":"小林,
