… which lead to transportation stops. This MSc thesis deals with the planning of logging operations and the problems that are involved in that process for SCA Forest and Timber. This study was initiated by the wood procurement and transportation department, Virke syd, and …
… from the forest in Sweden after pulpwood and lumber. Branches and tops i.e. logging residues are one of the assortments of fuel wood which is a common by-product after harvesting nowadays. The way to utilize, disintegrate and transport the logging residues varies between …
en systemanalys av effekter från avverkning till levererad virkesråvara
The costs of logging and of transportation with truck are dominating the total cost of wood delivered at industry. To support the profitability for the members' forestry the processing and handling with the timber has to be as efficient as possible. Increased length of pulpwood …
… cases would become pulpwood, is harvested as forest fuel together with the logging residues. The method is based on the assumption that advantages in handling of the forest fuel assortment such as increased load weights for forest hauling and truck transportation, should …
… This is because of prevailing pulpwood prices and because of high costs of logging and transport. To reduce these costs higher productivity is advocated. One way to increase the productivity is the use of multi-tree handling harvester heads. The aim of this study was to …
en tidsstudie av Vimek 608 BioCombi i contortabestånd
… annually be extracted as forest fuel. But harvesting small trees give high logging costs and new cost-efficient harvesting 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 …
During the transportation of logging residues (LR) the material´s low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was …

exploring the possibilities of modeling forest fuel markets in a regional partial equilibrium framework
… Sweden, such as; the need for better data on extraction and processing cost of logging residues, the need for better data on exogenous input costs in forest industries, and how the model results are affected by the choice of geographic scale of (trading) regions and related …
… data and data for different types of machines for comminution of logging residues. The lack of data and studies on GROT comminution makes it difficult to evaluate different chains for handling of residue fuels and make system analyses.Four types of machines with three different …
… to carry out time logs of the machines for some time during normal word rate. Logging data were analyzed and documented to be used as a basis for access to various measures to improve energy use. In some cases it was carried out with calculations with the value and data from the …
Flerträdshantering har sedan länge främst förekommit i gallringar och vid skörd av biobränslesortiment. På senare år har svenska och kanadensiska forskare även gjort tidsstudier på tekniken i slutavverkningar där resultaten visar på en ökning av produktiviteten. Inom Holmen Skog …
… strain gauges and pairs of perpendicular strain gauges, were tested. Power and logging of data was supplied through an Inertial Measurement Unit. The rein tension meters were calibrated by lifting known weights and were tested at local riding schools as well as with privately …
