Abstract:
The purpose of the study was to remove extra tensioning in the rope of tension winch and
to maintain constant tension. Tension winch is attached between the crane boom and the
trench cutter to create tension in a fixed rope. The problem was identified by the technical
operations manager/in charge of construction machinery. A study was carried out to solve
this issue. Various research papers, books and technical articles were consulted in order to
devise a method by changing the existing hydraulic circuitry to achieve constant tensioning
in the rope.
An optimized hydraulic circuitry was made for the purpose which finally resulted in a
solution that was more power efficient, economical and less space consuming than the
existing circuitry. Another major benefit was the increase in the cutter weight being exerted
on ground due to the removal of extra tensioning.
