Spravilo lesa iglavcev navzgor in navzdol z žičnim žerjavom Wanderfalke U-AM in univerzalnim vozičkom Sherpa U

Košir, Boštjan (author)

Prispevek je predhodno poročilo o meritvah učinkovitosti in nekaterih značilnostih spravila lesa iglavcev navzgor in navzdol z univerzalnim večbobenskim žičnim žerjavom s stolpom Wanderfalke U - AM, opremljenim z radijsko vodenim, avtomatskim vozičkom Sherpa U. Z meritvami časov smo dokazali, da je spravilo lesa navzdol do 17% manj učinkovito in do 20% dražje kot spravilo lesa navzgor. Pomembna je pravilna priprava dela, s katero močno zmanjšamo poškodbe stoječega drevja.

Abstract

The paper is a preliminary report on operational efficiency in timber skidding and some characteristics of uphill and downhill skidding of softwood by using a universal mobile tower yarder Wanderfalke U-AM equipped with a radio operated, fully automatic carriage Sherpa U. Work study of skidding indicates that the efficiency in downhill skidding can be as much as 17% lower and operational costs up to 20% higher than for uphill skidding. It is pointed out that proper work preparation is of essential importance, as it helps to minimize damage to standing trees.
