Changes in logging injury rates associated with use of feller-bunchers in West Virginia.
PROBLEM It is well documented that logging is one of the most dangerous occupations and industries in which to work, and trees fellers are at greatest risk of injury. The objective of this study was to determine whether West Virginia (WV) logging companies experienced a reduction in injuries after beginning to use feller-bunchers (tree cutting machines, which replace some of the work done with ...

15 صفحه اولSelf-Levelling Feller-Buncher Productivity Based on Lidar-Derived Slope
Nacrtak The purpose of the study was to examine the ability of LiDAR (Light Detection and Ranging) to derive terrain slope over large areas and to use the derived slope data to model the effect of slope on the productivity of a self-levelling feller-buncher in order to predict its productivity for a wide range of slopes. The study was carried out for a self-levelling tracked feller-buncher in a...
متن کاملOrthoprojection Tests of Hyperspectral Data in Steep Slope Zones
Nowadays hyperspectral data are really important in the environmental field. While the advantages, due to their radiometric features are broadly documented a rigorous metric verification is still absent especially in uneven areas (mountains) where the presence of steep slopes produces strong deformations on the images that have therefore to be preventively corrected. The classification potentia...
متن کاملSlope Length Effects on Soil Loss for Steep Slopes
cients. Normalizing to a unit plot of length 22.13 m, both the USLE and RUSLE use the equation Empirical soil erosion models continue to play an important role in soil conservation planning and environmental evaluations around L 5 (l/22.13) [2] the world. The effect of hillslope length on soil loss, often termed the where L is soil loss normalized to the 22.13-m-long slope length factor, is one...
