Abstract
A skyline intermediate support for use in cable logging systems and a logging carriage are shown and described. The intermediate skyline support permits the skyline cable to pass freely through the intermediate support while positively retaining the cable on the support, and allows the logging carriage to pass over the top of the intermediate support, with freedom to allow for a rocking motion in the carriage.
