Comparing the productivity and costs of extraction short and longwood

Abstract

Comparing the productivity and costs of extraction short and long wood. The aim of the studywas compare the effectiveness of extraction short and long wood, carried out on the same felling area.LKT 80 (set 1) and a Valtra 8050 farm tractor with Palms 10D forestry trailer equipped with Palms 4.70hydraulic crane (set 2) were used for the experiment. Set 1 transported long timber (> 6.0 m) on anaverage distance of 365 m with an average load of 3.44 m3. Set 2 transported short timber 2.5 m long, anaverage distance of 500 m, with an average load of 6.90 m3.The unit cost per hour of extracting longtimber with set 1 was € 38.93 h-1, and short timber with set 2 - € 31.68 h-1. At distances >170 m, shorttimber extraction is more cost-effective than long timber extraction.
