This document discusses the design of an electric car jack. It begins by providing background on mechanical jacks and how they use leverage to lift heavy loads. The main components of the electric jack design are then listed, including a 30 rpm DC geared motor that will provide torque to lift the jack. The objective is to design a reliable electric jack to replace mechanical jacks currently used in industries.

1. Presentation

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.
