芬兰最近10年提高采运机械化水平,将以采用多工序联合机为基础。1979年,全国使用了约130台这种联合机,其中86台打枝造材机,26台伐木打枝造材机,17台伐木集材机。据一家研究所的资料,到1982年,多工序联合机总数将达到400台,多工序联合机采伐量将占47%。预定初期,多工序联合机将主要用来皆伐大径级材。随着机器可靠性的提高,产生广泛应用多工序联合机的条件。此外,经济核算表明,在初期使用沿伐区或装车场移动的各种打枝造材机是合理的。可以预料,到80年代中期,伐木打枝造材机将占优势,从
In the last 10 years, Finland has raised the level of mechanization of mining and transportation and will be based on the adoption of a multi-process combined machine. In 1979, some 130 such tandem machines were used throughout the country, of which 86 were used, 26 were harvested, 17 are harvested. According to a research institute, by 1982, the total number of multi-process joint machines will reach 400 and that of multi-process joint machines will be 47%. Scheduled early, multi-process joint machine will be mainly used for clear cutting large diameter timber. With the improvement of the reliability of the machine, the conditions for widely used multi-process combination machines have arisen. In addition, the economic calculations show that it is reasonable to use a variety of sticking machines that move along the cutting or loading yard at an early stage. It is expected that by the mid-1980s, lumber raking machines will dominate from
