An Analysis of the Yarding Productivity and Cost in Forest Tending Operation

This study was carried out to analyze the yarding productivity and cost of the man-power operation by plastic chute, the yarding operation by yarder attached in tractor (Chuncheon Tower-yarder) and yarding operation by Tower-yarder (RME-300T) in forest tending operation. As result of average yarding timber volume was 0.67 $m^3$, 3.8 $m^3$ and 7.3 $m^3$ per day and man, respectively. And, when an yarding timber volume was 60 $m^3$/ha, the total yarding time including setting up and dismantling time of the plastic chute and yarding line was 20 days and 2 hours, 7 days and 1 hours and 21 minutes, 3 days and 4 hours and 27 minutes, respectively. The operation costs were 104,448 won/$m^3$, 29,968 won/$m^3$ and 23,032 won/$m^3$, respectively. And, when yarding timber volume was 60 $m^3$/ha, the total operation cost including setting up and dismantling time of the plastic chute and yarding line was 7,429,173 won/ha, 2,431,573 won/ha and 1,610,672 won/ha, respectively.

숲가꾸기 작업에서의 산물수집 공정 및 비용 분석

우리나라 숲가꾸기 작업에서의 산물수집 작업방법 중 플라스틱수라를 이용한 인력집재작업과 트랙터부착형 집재기(춘천집재기)를 이용한 집재작업, 타워야더(RME-300T)를 이용한 집재작업의 작업공정과 작업비용을 분석하였다. 조사지 3개소에 대한 평균 집재재적은 각각 0.67 $m^3$/일 인, 3.8 $m^3$/일 인, 7.3 $m^3$/일 인으로 나타났으며, ha당 집재재적이 60 $m^3$일 때, 수라 및 가선의 설치 해체 시간을 포함한 집재작업시간은 각각 20일 2시간, 7일 1시간 21분, 3일 4시간 27분로 나타났다. 또한, 작업비용을 분석한 결과, 단위재적($m^3$)당 집재비용은 각각 104,448원/$m^3$, 29,968원/$m^3$, 23,032원/$m^3$로 나타났으며, ha당 집재재적이 60 $m^3$일 때의 수라 및 가선 설치 해체시간을 포함한 작업비용은 각각 7,429,173원/ha, 2,431,573원/ha, 1,610,672원/ha으로 나타났다.
