We developed a rail type base machine to mechanize forest work on steep slopes. This machine runs on a rail way. It is composed of two vehicles: a power truck and a work truck. The power truck can run safely on slopes with inclinations of +-45 degrees. The work truck is equipped with four-leg type outriggers which are operate with a remote control device, a crane tilt mechanism in which the angle of the crane's central pillar can be adjusted within the range of +-35 degrees, and a grapple crane (reach: 8 m) with a winch for the logging and wood loading work. It can work even on inclinations of 30 degrees. As a result of a logging experiment, the work efficiency was found to be 1.37 cubic m/hr (8.2 cubic m/day). Thus, we will be able to mechanize forest work on steep slopes further by applying this machine and technology.
