An increase in ground-based steep-slope harvesting brings the need for a greater understanding of how machines can operate safely and efficiently on steep terrain.
FPInnovations, as part of its Steep Slope Initiative, recently conducted a study to investigate the sensitivity of different operating positions for non-tilting and tilting machines, and to propose a methodology for determining safe operating parameters.
The objectives of the study were to determine the expected operability range of both a non-tilting and tilting feller-buncher for a range of conditions based on stability, and to evaluate the influence of traction line orientation on machine stability.
The findings of the study, based on simulations using FPInnovations’ revised stability model, are presented in the report entitled The Effect of Machine Position on Stability When Operating on Steep Slopes, which is available online here.
“A methodology has been proposed in this report that could be utilized to assist operational planners and machine operators to determine suitable operability limits for steep slope harvesting applications,” explains Séamus Parker, Principal Researcher in FPInnovations’ Transport and Energy group.
This project was financially supported by Natural Resources Canada (NRCan) under the Transformative Technologies agreement between FPInnovations and NRCan.
