Abstract :
The lack of features for a properly designed gas
trolley has resulted in the manual handling of gas cylinder
tanks during transference, a common yet inappropriate
practice that is unsafe and physically strenuous. Using
principles of mechanism, an innovative gas cylinder trolley
was designed to maximize serviceability and effectiveness.
To corroborate the design, a computer simulation was
conducted and predicted the stress and strain
concentrations at maximum load. After fabrication, the
actual performance of the trolley was tested through actual
usage where a user experience survey was administered to
evaluate the performance of the trolley in terms of
mobility, stability, safety, comfortability, and
functionality. Based on the results of the survey, the overall
weighted mean of the user’s satisfaction level is 4.54 which
implies that the respondents were very satisfied with the
trolley design. Also, there is a significant difference in the
mean satisfaction level between the existing and new
designs. In terms of the force required to draw the trolley
on a plane surface, the new design trolley requires lesser
force (128 N) as compared to the existing design (256 N).
This innovation promotes the worker’s welfare and
security because of features that focus on the lifting,
handling, and restraining aspects. With this, safety isn’t
only achieved but also the worker’s efficiency and
productivity at work
