… study is an evaluation of mechanised pre-commercial thinning using the new Vimek 404R. Vimek 404R is a fairly small machine that permits selective removal of stems, making it potentially suitable also for areas overdue for pre-commercial thinning. The study established the level …
… thinning. The aim of this study was to quantify the productivity of a Vimek 404R light harvester with an accumulating Naarva-Grip cutting head during the bioenergy thinning of a self-regenerated stand west of Sunnansjö in Dalarna. The stand was birch-dominated, contained 15 371 …
en tidsstudie av Vimek 608 BioCombi i contortabestånd
… techniques are therefore required. The aim was to study the productivity of Vimek 608 BioCombi in forest fuel thinning of Lodgepole pine and to calculate the economy of the harvesting and estimate the thinning quality. The time study was performed in Åmarken in the county of …
en jämförelse mellan beståndsgående- och stickvägsgående maskiner
… den senaste tiden utvecklats, bland dessa utvecklare finns maskintillverkaren Vimek AB i Vindeln. Syftet med denna studie var att kvantifiera skillnader i gallringsresultat i tio bestånd gallrade med beståndsgående maskin typ Vimek, ”Vimekbestånd”, och i tio bestånd gallrade med …
… av biobränslet. Detta har lett till en viktig marknad inom svenskt skogsbruk. Vimeks inriktning inom detta område har varit hantering av energisortiment som uppkommer vid röjning och gallring. Under de senaste åren har Vimek utvecklat prototypmaskiner med mål att lösa …
The purpose of this report is to investigate and compare the difference between stand-thinning machines and strip-road thinning machines, and how they affect the stand on behalf of future growth, theoretical economic result, wind impact, snow pressure and density of stand. The …
