Performance of tools in tree felling and conversion in Changa Manga Forest Plantation

ABSTRACT
The performance of conventional and improved hand tools
in tree felling and conversion was tested in Changa
Manga Plantation in the basis of labour productively and
workload. The results of time and heart rate studies
showed that the improved tools demanded 12.4 minutes
less of work time per cubic meter of timber and firewood
converted. The technical labor productivity for work
with improved tools also higher by about 24% and this
increase was highly significant. Improved tools reduced
the physical workload in the workers highly
significantly as shown by their lower average total
pulse by 9 beats/min. These results indicate that
introduction of improved tools and vocational training
of forest workers are very essential for higher labor
productivity and improvement of socio-economic condition of forest workers in Pakistan.
