Abstract
Purpose of Review
The introduction of cable yarding systems has transformed timber harvesting operations on steep slopes. Subsequent adaptations and modernizations of rigging configurations, carriages, and work practices have led to substantial improvements in safety, productivity, and environmental performance. This review focuses on the base, or carrier, of the cable yarder and identifies recent improvements, thereby offering insight into emerging opportunities for future developments.
Recent Findings
Hybridization and electrification of carrier drivetrains, leveraging cable yarding's distinctive suitability for energy recuperation, has been introduced as a measure to enhance fuel economy and reduce CO₂ and noise emissions, thereby improving economic and environmental performance as well as occupational safety. The creation of a more attractive and safer working environment has been achieved through the increased use of excavators as carrier platforms for unguyed yarders, which have been instrumental in extending fully mechanized harvesting to steep slopes. In addition, this type of machine allows economic viability to be maintained in the smaller operations that are expected to be the norm in the future through lower machine costs and faster relocation. New information and communication technologies have made carriers a key source of machine sensor data for production control, monitoring and coordination, predictive maintenance and overall system optimization.
Summary
The yarder carrier, though often overlooked, is at the core of the evolution of cable yarding operations. The implementation of Forestry 4.0 technology is underway, and recent developments align with Forestry 5.0 principles to advance sustainable, safe, and economically viable harvesting in challenging terrain.
