The Effect of Yarding Technique on Yarding Productivity and Cost

چکیده
Cable yarding is a well establish technology for the extraction of timber in steep terrain. However, it encumbered with relatively low productivity and high costs, as such this needs to adapt progress remain viable. The development biomass valuable byproduct, availability processors support yarder operations, lend themselves increasing level whole-tree extraction. Double-hitch carriages have been developed allow full suspension tree-length material. This study compared standard single-hitch double-hitch carriage under controlled conditions, namely same location using downhill As expected, took longer load up (+14%), but was able achieve similar (10–11 m3 per productive machine hour) through increased inhaul speed (+15%). importance that demonstrates both physical economic feasibility moving type corridors, settings limited deflection, or areas lower tolerance soil disturbance.

Perspectives on Central European Cable Yarding Systems
Cable Yarding Technology has a long tradition in the Central European Alps. Outside Europe, sledge yarder technology became well known during the 1960's while the first European tower yarders were introduced during the 1970s. Although there has been much effort to improve yarding technology, only little is known about it outside Europe. The paper aims to present the state-of-the-art of both, ya...
