Analysis and Fabrication of Remote Control Lifting Jack

With the increasing levels of technology, the efforts being put to produce any kind of work has
been continuously decreasing. The efforts required in achieving the desired output can be
effectively and economically be decreased by the implementation of better designs.
Power screws are used to convert rotary motion into translatory motion. A screw jack is an
example of a power screw in which a small force applied in a horizontal plane is used to raise or
lower a large load. The principle on which it works is similar to that of an inclined plane. The
mechanical advantage of a screw jack is the ratio of the load applied to the effort applied. The
screw jack is operated by turning a lead screw. The height of the jack is adjusted by turning a
lead screw and this adjustment can be done either manually or by integrating an electric motor.
This research paper analyzes the modification of the existing motor screw jack by incorporating
an electric motor in the screw in order to make load lifting easier. In this modified design, the
power screw is rotated by connecting motor through universal coupling, plugged to the
automobile 12 V battery source to generate power for the prime mover (motor), which transmits
its rotating speed to the power screw to be rotated with required speed reduction and increased
torque to drive the power screw. The significance and purpose of this work is to modify the
existing car jack in order to make the operation easier, safer and more reliable in order to
reduce health risks especially back ache problems associated with doing work in a bent or
squatting position for a long period of time. The modified car jack is easy to use by women or
whoever had problem with the vehicle tyres along the road. The designed motorised jack will
also save time and requires less human energy to operate.


A revolutionary change has taken place in the field of Fluid Power Technology due to the integration of electronics as a control medium for hydraulic components and systems. Due to sophistication of hydraulics and allied fields of power and higher accuracy in speed, force and position control. Efforts have been made to include the latest possible trends in the field of hydraulics and allied control areas to keep the ever changing state of the technology in hydraulics.
Now a day more stress is given to LUXURY, COMFORT and SAFETY as much as possible with money and TECHNOLOGY available with the mankind. In that way to help those who are physically challenged this project is been made. That is a case of lifting a jack to an automobile, is troublesome to physically challenged human being. And we are using oil, hence the jack as a means of power transmissions. Hydraulic systems are now extensively used in almost all the engineering fields in varied applications. So we tried to grab the opportunity.
Energy can neither be created nor be destroyed but it can be transformed from one form to another. The energy associated with human beings will decrease as he becomes older resulting unable to challenge physically. To overcome we have provided alternate source of energy by taking the power from wiper motor to drive the hydraulic jack loading subsequently and automatically, which substantially reduce the burden.
Our project works on the mechanism of converting rotary motion of the wiper motor into reciprocating motion of the hydraulic jack plunger. A cylinder cage structure of wiper motor ensures maximum power delivered by consuming the available battery power which can be easily generated. Important thing is that the power is available at any instant and anyone can withdraw easily, without any hazard.
Realizing that the engineers are more concerned with the applications than with theory, we have woven the subject-matter with this practical application in engineering and achieved the objective. Addition of number of figures, tables and examples is in proportionate to the addition of written word because they offer better visual appreciation and mental grasp.
