Abstract:
Artisanal mining in Uganda has seen a great rise in the last three years; this rise is currently
boosting extraction of ore by majorly reusing mining method where their productivity is majorly
affected by ore conveyance to the surface as majority uses the traditional methods of rope
pulling, suck and basin carrying. Due to growth of technologies requested higher performance
machine in order to fulfil human needs and market. This machine is implement to make human
work easier besides can reduce the use of human power because of its potential application.
Earlier on people would carry manually using basins, sucks and pull using the rope at a time and
while returning it does not give any useful work. So with this disadvantage thought of attaching a
bucket on the hoist operated by one crank shaft, when one bucket moves up with the ore and
goes back empty without a person carrying it to pick more. The machine is based on the
principle of lifting machine which can elevate a variety of bulk materials from light to heavy
depending on the size, weight, and nature of the load to be moved.
Therefore, this project is aimed at design and construction of a hand driven single hoisting system
to improve on the productivity and Specific objectives are to design the various components of
the proposed machine, assemble, test and evaluate the economic feasibility of the machine.
In this design, measurement and experimentation is to be considered, specifically on rock factors
such as; average ore size. Experiments will be carried out on the single hoist system which will
help in the rotation design. The prototype is to be constructed by welding and bolting with the
provision of manual power unit, tested for its lifting efficiency, output capacity and cost benefit
