止できる。According to the present invention, a traveling wheel which can travel on a striated body stretched substantially horizontally, and travels in contact with a second striated body provided in parallel with the striated body. A possible auxiliary wheel, a rotary drive mechanism for rotating and driving the traveling wheel, a logging mechanism for performing a logging operation with a blade for cutting trees, and a rotary drive mechanism and a logging mechanism for receiving a remote control signal and receiving a remote control signal. Since the system is equipped with a receiving and control unit that operates, it is possible to cut trees by running a tree cutting device by remote control from the ground, for example, making it extremely efficient to cut trees over a wide range. This makes it possible to save labor. In addition, it is unnecessary for the worker to climb the tree, except when the tree cutting device is attached to the striatum, so that there is no need for heavy labor. Since the worker does not need to approach the electric wire except when the tree cutting device is attached to the striatum, the safety is improved. In addition, since the auxiliary wheels that can travel in contact with the second striated body are provided separately from the traveling wheels that run on the striated body, stable traveling is possible and the reaction force at the time of logging is received. Logging can be done smoothly. Further, since the posture of the tree cutting device does not collapse due to the reaction force of the cutting, there is no possibility that the tree cutting device will fall. Further, even if the traveling wheel is derailed, the auxiliary wheel supports, so that the tree cutting device can be prevented from falling.
