This capstone project looked at how small and medium-sized automotive workshops still
handle engines and transmissions manually, which can lead to injuries, safety risks, and
less efficient work. While there are lifting devices such as hydraulic cranes and automated
hoists, many are too costly, too large, or impractical for smaller workshops and teaching
labs. This shows there is a need for a more affordable, ergonomic, and semi-automated
lifting tool for sedan engines and transmissions. The main goal of this study was to design,
build, and test an electric trolley with a semi-automated hoist that can safely lift, rotate,
position, and move sedan engines and transmissions. The team used a prototyping
approach, which included designing and modeling the system, building it with locally
available materials, and running thorough performance tests. The evaluation covered load
capacity, ease of movement, rotation accuracy, operation of the electrical and thermal
systems, and whether the safety features functioned properly. Tests showed that the
prototype could reliably handle up to 150 kg, both with and without a load, without
becoming unstable, vibrating too much, or moving unsafely. The system lifted and lowered
smoothly, rotated in a controlled way, and was easy to move around in a typical workshop.
These results suggest that the new system makes handling engines and transmissions easier
and safer. In summary, this project offers a practical, affordable, and ergonomic lifting
solution for automotive repair shops and teaching labs, helping to improve safety,
efficiency, and hands-on automotive skills.
