Direct Driven Hydraulic System for Skidders
Energies, 2022 This paper investigates potential uses of a novel direct driven electro-hydraulic systems for articulated forestry tractors (skidders), due to these systems having notably higher energy efficiencies compared to classical electro-hydraulic systems that ...

Soil compaction caused by 450C Timber Jack wheeled skidder (Shefarood forest, northern Iran)
Journal of Forest Science, 2007 In forest harvesting operations usually after using skidding machinery (skidders), traces of soil damage in the form of soil compaction and wheel and logs ruts can be seen in the forest soil. Soil bulk density, which represents soil compaction, decreases

Skidder Operator Vibration Exposure
, 2021 The exposure of workers to vibration is expressed as energy equivalent A(8), which is determined by the procedure clearly described in the international standard ISO 5349-1-2001. A(8) is a value that depends not only on the vibration level in certain operating procedures, but also on the duration of exposure. Research was conducted on Ecotrac 120 V and

Economics of forest biomass for bioenergy: potential site preparation savings from coarse woody harvesting residue removal in a short-rotation Eucalyptus globulus (Labill.) plantation [PDF]
Silva Balcanica, 2021 The study used time studies and cost analysis to assess potential economic benefits from site preparation cost reductions resulting from producing coarse woody harvesting residue (CWHR) for bioenergy. In contrast, previous studies have predominantly used
