Abstract

A study was conducted on chip production from logging residue left after a cable yarder operation. The logistics were managed with tractor and trailer units (shuttles). The study specifically dealt with a very difficult case of space constrained operations, further expanding the knowledge about chip supply in extreme work conditions. The focus of the investigation was also extended to the shuttles. The study tested a production chain, in which only 3 machines (1 chipper, 2 shuttles) were used to minimize operational costs. The use of 2 shuttles was decisive, reducing shuttle delays. The chips produced had an average moisture content of 40.2 %3.1%. Particle size distribution shows an unfavorable composition. The content of accepts is as low as 72%, while oversized particles get up to 5.4% and fines rise to a maximum of 24%. The estimated net productivity of the whole system was 11.5 t PMH-1, corresponding to a gross productivity of 11.1 t SMH-1. The cost of the whole operation amounted to 21.2 Et-1.
