Button-activated for ease-of-use and improved safety in emergency situations. (PDF) Development of Auto Car Jack Using Internal Car Power

The calculations aimed at overcoming a 17.631 N.m torque requirement to lift 850 kg.

Parts created using milling and grinding machines, simulated via Solidworks.

A scissor jack redesigned to integrate a 12-volt DC motor, meant to be powered by the car's own cigarette lighter.

Elias shuts down the laptop and compresses the files. He knows this isn't just a project; it's a future where a 12-volt motor does the heavy lifting, sparing the driver from the physical strain. He moves the Car Jack off.rar file into his "Completed" folder, knowing the next time a car sits helpless on the side of the road, it won't be for long. Key Technical Takeaways of the Project

Development of an automatic car jack utilizing internal car 12v power for emergency use. Engineering: Achieves a torque of through a gear ratio mechanism. Capacity: Designed to lift vehicles up to , such as a PERODUA Kancil.

The air in the workshop is thick with the smell of hydraulic fluid and ozone. Under the harsh glare of a single overhead bulb sits a battered '05 sedan, resting unevenly on three wheels. Elias—an engineer with grease permanently stained under his fingernails—is staring at his laptop, where a complex Solidworks simulation is rendering, titled carjacker_v7.stl .

Elias isn't just repairing the car; he's correcting a flaw in design. Last winter, he struggled to jack up this same car on a snowy roadside. He realized the mechanical jack—the staple of the roadside kit—was a piece of 19th-century technology in a 21st-century world. He promised himself: never again.
