Abstract

A primary problem for mechanics and automotive enthusiasts is the risk associated with lifting and securing a vehicle with conventional jack stands. Often times, improper jack-stand installation results in the vehicle collapsing unexpectedly, causing injury and/or death. This problem can be minimized through the application of a newly re-designed vehicle lifting system. The conventional method for lifting cars is time consuming and can be unsafe in many circumstances. A better, safer, and more efficient lift design was needed; the AutoJack. The approach of the AutoJack design was entirely focused on the safety of lifting a vehicle. Safety was improved by creating an automated, hydraulically powered system that doesn’t require the user to maneuver under the vehicle to lift or position jack stands. In doing so, the design has removed the operator from a potentially hazardous environment, maximizing safety. The frame design of the AutoJack features a contact area of 4 square feet, a massive improvement over the 4in2 standard stability area. Compared to the standard 2-ton floor jack, the AutoJack has a 500% increase in maximum load capacity, a 27% greater maximum lift capacity, a lift speed increase of 100% (2in/s to 4in/s), an operational time reduction of 30%, a jack-to-vehicle contact area (safety) increase of 14,400% (4in2 to 4ft2), and a total cost reduction of 40%. The AutoJack is also user-friendlier since the user is only required to slide the device under the vehicle. This device maximizes safety while saving time and money.The AutoJack will save lives.
