Design and Fabrication of Car Wheel Multi Nut Remover

The aim of this work is to design and fabricate a hand operated tool used for screwing and unscrewing of car tire nuts which is known as Multi Nut Remover. Mostly, the tire nut remover and a jack are provided with car for tire replacement. But, due to difficulty in applying required torque and to save consumption of time, we have successfully developed a multi nut remover which is having a gear mechanism. The Modelling of Multi Nut Remover is done in SOLIDWORKS 2017 Software and later experimental setup was fabricated. After performing various Experiments on Multi Nut Remover experimental setup we came to know that the torque required to remove all nuts and time are less compared to jack and other tire replacement techniques. So, this Multi Nut Remover can find its application in garages, workshops and service stations. The multi nut remover is designed to be ergonomic, easy maintenance, easy storage and easy to handle. This tool is tested and found suitable for various field applications.
