An Experiment to Analyze Prebunching With a Low Investment Skyline Yarder as and Economical Approach to Thinning Young-growth Pacific Northwest Timber Stands

Purpose

The experiment will use each skyline road as an experimental unit. Ten units will be laid out, each 1,00 ft. by 250 ft. wide. Four units will be assigned as silvicultural control units. Two will be assigned as thinning control units and will be logged

Lateral Yarding Mechanics

Purpose

(1) Measure dynamic mainline tension, vertical angle of the mainline, and mainline displacement during lateral inhaul from the initial movement of the turn until it reaches the carriage. (2) Correlate maximum mainline tension and occurrence of hangups dur

Bar code feasibility study

Purpose

This study will be done to determine how well log design bar code tags withstand the rigors of the yarding process. 50 to 100 logs will be tagged with 3 tags being applied to each log; one on each face and one on the side near an end for a total 150 to 30
