Impact on Soil Bulk Density Caused by Using Buffaloes (Bubalus bubalis) in Timber Skidding
, 2019 La degradación de la estructura del suelo producto del aprovechamiento de plantaciones forestales constituye uno de los aspectos más importantes a considerar durante la producción de madera reforestada. Entre los factores que más acentúan esta degradación se encuentra el método de extracción empleado, por esta razón, se evaluó el efecto sobre el suelo ...

Modeling the effect of skidded timber bunches on forest soil compaction
The Journal of Defense Modeling and Simulation: Applications, Methodology, Technology, 2020An increasing demand for forest products incites a large number of log transportation operations, which may lead to negative consequences for the soil and the ecosystem as a whole. This paper presents a mathematical model to estimate the soil deformation and compaction processes under the influence of individual components of the skidding system, such ...

Critical slope in downhill timber skidding [PDF]
, 2015 Skidder’s ability to extract timber is defined by: 1) basic dimensional features of the vehicle, 2) the ability to overcome obstacles during movement, 3) traction performance and 4) environmental soundness. Traction performance depends on the ground conditions (soil bearing capacity) and the total effect of all forces on the vehicle.
