2. Introduction
 A jack is a mechanical device used to lift
heavy loads or apply great forces.
 It is a design for lifting cars, vehicles etc.
 A mechanical jack is a device which lifts
heavy equipment.
 Car jacks usually use mechanical
advantage to allow a human to lift a
vehicle by manual force alone.

3.  The motors used in this project are D.C.
motors.

4.  The conversion of electrical energy into
mechanical energy by a electromagnetic
means is demonstrated by the British
scientist Michael Faraday in 1821.
 Jedlik's "electromagnetic self-rotor", 1827.
(Museum of Applied Arts, Budapest. The
historic motor still works perfectly today.)

5.  A screw jack is a mechanical device that can
increase the magnitude of an effort force.

6.  A jackscrew is a type of jack which is
operated by turning a leadscrew.

7. THE STUDY AREA
 The main area for this study is to choose
the best deisgn possible for the lifting
mechanism and to install the electric
motor interface with the jack
 A 30 rpm DC Geared motor for the
design due to its high torque and
sufficiently high power to lift the jack up
and down.

8. LIST OF COMPONENTS
USED
 Base Plate
 Springs
 Pillar Blocks
 Linear Actuator
 Nut-Bolt Pair
 DC Geared Motor
 Battery 6V
 Rectangular Plates

9.  Switches for remote
 PCB for remote
 Allen Bolts ( 5X10,5x16,4x10 )
 Collars ( OD=25, ID=12) , thick=15
 Mechanical Framework for whole project
(base)

10. Objective
 The aim of our project is to design an
electric jack to lift the vehicle with the
help of electric current through a motor
(dc geared)
 Thus this project helps in replacing the
mechanical jacks used in industries with
more easily operated and reliable
electric jack.
