Description
Steep-terrain forestry ($>30^\circ$) demands a radical departure from conventional machinery to balance operational efficiency with soil protection. This study evaluates a dual-solution framework developed by MSE: the "Shin-Raptor II," a specialized 6,400 kg class lightweight winch-assisted (WA) base carrier, and the "Feller Buncher Saurus (FBZ)," an innovative attachment for integrated earthworks and harvesting.The Shin-Raptor II is a specialized platform that redefines steep-slope felling by eliminating the conventional crane arm. Its compact 6,400 kg design, combined with a unique chassis-integrated felling architecture, maintains an exceptionally low center of gravity and minimizes soil impact. Powered by a fully synchronized Winch Assist (WA) system, this lightweight machine achieves superior vertical mobility and high-traction performance on $45^\circ$ slopes where traditional heavy harvesters fail. Its $10^\circ$ engine-oscillation mechanism further ensures operational reliability under extreme tilt.Complementing this specialized carrier is the FBZ, designed to transform standard $0.45~m^3$ class hydraulic excavators into multifunctional infrastructure units. The FBZ uniquely integrates a $0.45~m^3$ excavation bucket with an eccentric pull-cut blade, enabling a single machine to perform slope profiling, stump removal, and road construction while simultaneously executing high-speed felling. This integrated workflow significantly reduces machine traffic and operational costs by eliminating the need for separate road-building equipment. Furthermore, its "pull-cut" geometry allows for the efficient processing of high-density broad-leaved timber. Together, these technologies provide a scalable framework for precision forestry, balancing extreme mobility with comprehensive operational versatility.
