In terms of progress and improvement for any organization, the worth of a human life cannot be understated. Standard and proper tools and equipment are used in several businesses, garages, and workshops to guarantee the safe, effective, and quick completion of tasks while also preventing injuries and fatalities. The use of a car lift is essential for the majority of automotive repair, maintenance, and service tasks. These lifts eliminate back pain, prevent injuries, and make workers more efficient and timely. This paper details the planning and evaluation of an upgraded four-pole lift system that will raise the vehicles off the ground in a safe and efficient manner, allowing access to their undercarriages and bringing them to a more comfortable working height for the operators. Among the many innovative features and capabilities included in the design is the ability to tilt the vehicle from either the front or the back, raise the whole vehicle, or lift either the front or rear end. Additionally, there is a simple mechanical lock at each pole. The device's efficacy in lifting weights up to 7 tons was determined by comparative study after the necessary load capacity and preferred materials—structural steel, cast iron, and carbon steel—were determined. According to the findings of the design's static structural analysis, the corresponding Von-Misses stresses for structural steel, cast iron, and annealed carbon steel are 50.4MPa, 66.9MPa, and 51.4MPa, respectively. When compared to cast iron, structural steel and carbon steel 1020 annealed have the lowest deformation values. Following the imposition of maximum loads without failure that exceed the rated load of light-duty vehicles, the unit is deemed safe for operation.
