Introduction
 A screw jack is a device by which a heavy
load can be lifted by applying very little
force.
 Car jack is a type of the screw jack which is
generally used to lift the car specifically
when the car is to be repaired.
Automatic Screw Jack
It is a type of jack that is operated by Turning
Lead Screw.
Components
Frame Motor
Screw Jack Battery
Frame
Frame is
generally used
for supporting
the entire load of
the Screw Jack.
Motor  Motor is generally used to
transmit Rotary Motion to
Reciprocating Motion.
 Specifications of Motor
Used in this project:
POWER – 12 W
RPM - 36 TO 40
Rotation – Both Direction
Sound – 50 db (Low
Noise)
Shaft
A Shaft is used to
transmit power
from Motor to the
Jack which is
coupled to it.
Battery and Switches
 A 12 Volt (7.5 Ah and
initial current – 2.1 A)
battery is used in this
project to run the
Automatic Screw Jack.
 Switches are used to
provide current to the
Jack according to the
required work.
Cost of Components
Motor 800
Battery 1200
Screw Jack 800
Shaft 100
Frame 400
Switch 100
Labour Cost 200
Advantages
 No physical labour or man power is
required to lift the
car.
 Easy to handle.
 Portable.
 Light weight.
 It can lift up to a weight of 3 tonnes.
