It required special techniques and much manpower to construct chutes and to prehaul logs to the chutes. Of late, chute logging seldom has been seen. However, now it is being reviving in Japan to transport logs from thinnings. Such chutes are designed as portable units of aluminum-alloy or glass-fiber (FRP). They are capable of high productivity when the routes are located suitably, and the logs are stacked along the chutes. We constructed a nearly-straight course of 50 m made of portable aluminum-alloy sections in the University of Tokyo Forest at Chichibu and investigated its characteristics for logging.
