| Research Abstract |
Recently in Japan, small-sized forestry vehicles are widely used especially for logging operations in private forest. The purpose of this study is to develop forestry vehicles with a prehauling function employing a running-skyline system for improving prehauling operations. The outlines of the results obtained from this study are summarized as follows; 1.Some specifications of the developed vehicle: (1)Overall lengthxOverall widthxOverall height: 4,650x1,600x5,250 mm (2)Total weight: About 3,000kg (3)Rated horsepower of the engine: 33 PS. 2.Performance: (1)Base machine: Max. speed 10 km/hr, Gradeability 35 degree, load carrying capacity 1,800 kg (2)Winch: winding force 730 kg, winding speed 1.3 m/sec (3)Grapple loader: Reach 4.2 m, Lift 360 kg. 3.Operational efficiency: Volume prehauled per operating hour by the developed vehicle was estimated at 9 M^3 at prehauling distance of 100 m, and 6 M^3 at 50 m. 4.The developed vehicle was evaluated as compared with conventional vehicles with a crane (1)Operational efficiency: About 2 times (2)Prehaulable distance: About 2 times (3)Labour productivity: About 3 times (4)Cost of prehauling operations: About a half.
