Timber harvesting tools and work stress in irrigated forest plantations
Timber harvesting tools and work stress in irrigated forest plantations
M. Ayaz
ABSTRACT
A study was carried out in Changa Manga forest
plantation in 1984-85 for the comparison of conventional
and improved tools in timber harvesting on the basis of
technical labour productivity under an equal and
maximum work stress. Result of the study reveal that the
technical labour productivity of conventional and
improved tools at maximum work stress is 0.47 and 0.61m3
of timber and firewood per man hour respectively.
Improved tools were found to have (30%) higher
productivity than conventional tools in tree felling and
conversion and therefore were recommended for
introduction in timber harvesting in Pakistan.
