Paper Details

This paper analyzes the modification of the existing screw jack by incorporating an electric motor in the screwinorder to make load lifting easier. In this modified design, the power screw is rotated through its connecting gear with thepinion gear which transmits its rotating speed to the pinion gear meshing with the bigger gear connected to the power screwto be rotated with required speed reduction and increased torque to drive the power screw. The significance and purpose ofthis work is to modify the existing car jack in order to make the operation easier, safer and more reliable in order to reducehealth risks especially back ache problems associated with doing work in a bent or squatting position for a long period oftime. The modified car jack is easy to use by pregnant women or whoever had problem with the vehicle tyre along the road.The designed jack will also save time and requires less human energy to operate. The design when adopted will effectivelycurb the problems associated with Ergonomics - which is a fundamental concept of design process. The Design a mechanicalscrew jack is for Mercedes e class having weight 1400kg and ground clearance 180mm.
