Design, analysis and fabrication of wheel dolly jack / Muhammad Haiqal Danish Ahmad

Jack has played an important role in human history as a device that use mechanical mechanism to amplify force in order to lift heavy objects beyond human capabilities [2]. Wheel dolly jack is an improve version of the earlier jacks that was more mobile and able to carry more weight. Wheel dolly jack are usually use to move vehicles out of inconvenient space. However, its huge size takes too much space and causing it to only be use in a certain condition [3]. Because of this problem, only mechanics and towing services uses this wheel dolly jack. There’s also the problem with the Wheel dolly jack is not very known by the public causing it to be rarely used in emergency. This is a huge problem as vehicles breakdown frequently happen due to the nature of a machine and causes user to be stranded on the side of the road or in a dangerous spot until tow services arrive [4]. Even worse, some vehicles breakdown happens in the middle of the road and could lead to an accident. This is very dangerous especially for female driver who was often target for criminal acts such as hijacking, intimidation and sexual assault [5]. That’s why it’s a necessity to have a wheel dolly jack to move the car to safety and away from a vulnerable spot. The aim of this project is to design, analysis and fabricate the wheel dolly jack then to modify it to become more easier to use. I used SOLIDWORKS software to design my product and use polishing, welding, cutting, milling and bending technique to fabricate the final product. The final product has accomplished my goal to become a functional wheel dolly jack and more user friendly. With this product, driver especially female driver can easily move their vehicles without needing more manpower.
