Abstract
Automobile workshops frequently need to move vehicles or individual wheels for inspection, repair or storage. Conventional methods involve significant manual effort and risk of injury or damage. Wheel dollies equipped with hydraulic and ratchet mechanisms offer controlled lifting and secure positioning.
This project develops Design and Fabrication of Car Wheel Dollies using Hydraulic Ratchet Mechanism. A hydraulic jack provides the lifting force while a ratchet system allows incremental adjustment and positive locking of the raised position. Key subsystems include the frame, hydraulic cylinder/jack, ratchet and pawl assembly, load rollers or casters, and safety stops. The unit demonstrates practical application of hydraulic power, machine design and workshop ergonomics suitable for academic evaluation.
It is an excellent final-year project for Mechanical, Automobile, Production, Manufacturing and Industrial Engineering students, combining fabrication, hydraulics and real workshop utility.
