Abstract
Modern running skyline systems best meet current requirements for logging on steep terrain. These requirements can be stated as the need to economically harvest timber over extended distances on a variety of terrain conditions in an environmentally acceptable manner. Three different methods of tensioning the running lines are used by the manufacturers of running skyline yarders. These include a non-interlocking method and two interlocking methods. The best control and efficiency are obtained with a hydraulically controlled differential drive.
