Mountain forests in Japan are steep with weak subgrades and many obstacles on the ground surface. The forest road density is also low (16 [m/ha]). This means that forest workers have to travel in forest areas with no roads while carrying loads. The authors have developed a movement and conveyance machine based on a crawler for the purpose of use in forest areas. This report proposes a crawler mechanism equipped with a new suspension mechanism and shows the effectiveness of the proposed mechanism in an actual trial.
