集运机是国外、尤其是北欧的主要集材机械,一般都是四轮或六轮驱动,折腰转向,机动灵活,越野性能强,特别适合径级较小的造纸材和原木的集材作业,不但适用于主伐,也适用于抚育采伐,是值得我们注意的一种先进集材机械。我国伐区用的动力机械,现在已基本上饱和,因此一般认为研制新的伐区机械,在国民经济调整时期似无多大意义,对于集运机的技术也无引进的必要。我们认为,根据我国森林资源的情况,在今后相当长时期内,木材采伐量将稳定在现有的水平,采运机械首先应把重点放在现有设备的使用管理上,充分挖掘现有设备的潜力,提高使用
It is the main material-collecting machinery abroad, especially in Northern Europe. It is generally four-wheel or six-wheel drive with turning, turning flexible and strong off-road performance. It is especially suitable for the timbering operations of papermaking logs and logs with smaller diameters. For the main cutting, but also suitable for tending, it is worth noting that we are an advanced timber machinery. The power machinery used in our country’s cutting areas is now basically saturated. Therefore, it is generally considered that the development of new cutting-zone machinery is of little significance during the period of national economic readjustment, nor is it necessary for the technology of the aircraft to be imported. In our opinion, according to the situation of forest resources in our country, timber harvesting volume will be stable at the current level for a long time in the future. The mining and transportation machinery should first focus on the use and management of existing equipment and fully tap existing equipment The potential to improve use
