Abstract

This study was conducted in clear cutting stands. For the whole-tree yarding operation, a tower-yarder based on excavator with a radio-controlled double clamp carriage was applied to analyze yarding productivity and cost. The productivity and cost of yarding operation was $6.2m^3/SMH$(machine utilization rate, 80.4%) and $13,705won/m^3$, respectively. Although the maximum yarding distance was longer than the previous studies, the setting up time of the tower-yarder was decreased as used straw line. The application of the radio-controlled double clamp carriage improved productivity and reduced costs. Based on the fuel log and growing stock($137.0m^3/ha$), the minimum production($m^3$) and area(ha) were $558.3m^3$ and 4.1 ha for Pinus rigida stands and $433.7m^3$ and 3.2 ha for Quercus mongolica stands, respectively. Based on the this study, it will be possible to select an efficient yarding machine by accumulation of data on minimum production and area for many machines in various harvesting sites.

본 연구에서는 모두베기 작업지에서 2중 무선 클램프 반송기를 적용한 굴삭기 기반 타워야더의 집재작업 생산성 및 비용을 분석하였다. 집재작업의 생산성은 $6.2m^3/SMH$(기계이용률 80.4%)이고, 비용은 $13,705won/m^3$으로 나타났다. 이 결과는 기존 연구결과에 비해 최대 집재거리가 길었음에도 불구하고 가선설치용 견인줄(Straw line)을 이용한 가선설치로 집재선 가선설치 시간이 단축되었으며, 2중 무선 클램프 반송기 적용으로 인해 생산성이 향상되고 비용이 절감된 것으로 나타났다. 또한, 원료재급과 임목축적 $137m^3/ha$ 기준으로 집재작업의 생산재적에 따른 최소작업량과 최소작업면적은 리기다소나무의 경우 각각 $558.3m^3$ 및 4.1 ha였고, 신갈나무의 경우 $433.7m^3$ 및 3.2 ha로 나타났다. 향후, 다양한 작업현장에서 집재기계별 최소작업량 및 최소작업면적에 관한 데이터를 구축하면, 집재작업에 효율적인 집재기계를 선정할 수 있을 것으로 판단된다.
