摘要： Apparatus for in-forest cutting of lumber from felled logs is provided. The apparatus comprises a frame mounting a pair of wheels around which is trained a band saw blade. A chain saw engine is releasably connected to the frame and is coupled to one of the wheels for driving the saw blade. A carriage is mounted to the frame and is adapted to extend lengthwise of the log to enable the frame to be advanced along the log as the saw blade cuts. The carriage has a series of resilient rollers which cooperate with blade guide and stabilizer assemblies to provide a straight cut. Handles are provided at opposite ends of the frame to enable workmen to mount and to dismount the apparatus and to advance the same along the log.
摘要翻译： 提供了从砍伐原木进行森林砍伐木材的设备。 该装置包括安装一对轮的框架，围绕该框架训练带锯片。 链锯发动机可释放地连接到框架并且联接到一个车轮以驱动锯片。 托架安装到框架上并且适于沿木材的纵向方向延伸，以使得框架能沿着锯片切割而沿木材前进。 滑架具有一系列弹性辊，它们与刀片引导件和稳定器组件配合以提供直线切割。 在框架的相对端设有把手，以使工人能够安装和拆卸设备并沿着原木推进。
