Kappa Kraftliner i Piteå använder sig i dagsläget av pneumatiska transportsystem för Flistransport mellan sållstation och kokeri. Dessa system är mycket energikrävande. Eftersom energipriset har ökat kraftigt i början på 2000-talet har frågan om det är lönsamt att byta Flistransportsystem till något mindre energikrävande kommit upp. Examensarbetets uppgift är således att ge svar på denna fråga. Vid arbetets start fanns även kravet på dubbla transportörer, för att få mycket hög driftsäkerhet.

Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.
