DESIGN AND FABRICATION OF TOGGLE JACK FULL REPORT DOWNLOAD

The most basic Toggle jack design is truly engineering at its finest. With the power to magnify input forces, Toggle jacks allow us to raise vast loads using only a fraction of the force ordinarily needed. Our goal in this project is to design an efficient Toggle jack capable of raising a 10000N load. As a screw-driven mechanical system, the jack will be manually operated and have at least 7 inches under load. The design will be transportable and storable, have a removable crank handle, and operate with a factor of safety of n = 5 using standard mechanical design methods for all components. The design itself has gone through multiple stages of development. We have taken several possible failure modes into account and are confident that our design is efficient and safe.

Our proposed design is similar to common Toggle designs in some aspects, but also advantageous in others. Similar to others, our proposed design can safely raise a load of 10000N to the required heights with relative ease on the user. Unique to our design, however, is the manufacturability of our design, which is much simpler. Since only Bar-shapes are utilized, bulk material can be more efficiently purchased and used. Also, less machining is required since there are no complex sleeves for the power screw. Only simple attachments which can be welded on are proposed. Therefore, when compared to similar Toggle jack designs that perform equally as well, our proposed design is recommended for its manufacturability and lower cost with high efficiency.
