This document describes a project to design and fabricate a quick lifting jack using pneumatic systems to lift vehicles. It aims to address the difficulty in lifting vehicles manually in auto garages. The lifting jack uses a pneumatic cylinder connected to a solenoid valve to lift vehicles smoothly without impact. When the solenoid valve is turned on, pressurized air enters the cylinder to push the piston up and lift the vehicle. The lifting jack is designed to be simple and economical for use in small and medium auto garages. It allows vehicles to be lifted with less manpower than conventional jacks.

FABRICATION OF FOUR SIDE PNEAUAMTIC
LIFTING JACK
SYNOPSIS
This project work titled “FABRICATION OF QUICK LIFTING JACK” has
been conceived having studied the difficulty in lifting the any type of light vehicles.
Our survey in the regard in several automobile garages, revealed the facts that
mostly some difficult methods were adopted in lifting the vehicles for reconditioning.
Now the project has mainly concentrated on this difficulty, and hence a suitable device
has been designed. Such that the vehicle can be lifted from the floor land without
application of any impact force.
The fabrication part of it has been considered with almost case for its simplicity
and economy, such that this can be accommodated as one of the essential tools on
automobile garages.
This device the quick lifting jack with Pneumatic arrangement for automobile
garages has been developed to later the needs of small and medium automobile garages,
who are normally man powered with very minimum of skilled labours. In most of the
garages the vehicles are lifted by using Pneumatic jack. This needs high man power and
skilled labours. In order to avoid all such disadvantages. This, Quick Lifting jack has
been designed in such a way that it can be used to lift the vehicle very smoothly without
any impact force. The operation is made be simple that even an unskilled labour can
handled, by just demonstrating the working of the Quick Lifting jack once.

2. The Pneumatic Cylinder is connected with the Solenoid valve mechanism. The
Cylinder Piston moves up and down depends upon the Solenoid Valve ON/OFF
Condition. This is a simple type of automation project.
The block diagram of quick lifting jack is shown in fig. The On/Off Switch is used
to drive the Solenoid Valve. The Solenoid valve is connected on the Pneumatic Cylinder.
If the Pressurized Air is apply to the Pneumatic Cylinder, it will Move for the Cylinder
Piston. The Piston movement is up and down motion due to Pneumatic Cylinder
Mechanism.
So the pressurized Air goes to the Pneumatic Cylinder and moves the piston
upward, so that the vehicle lifts from ground.
ADVANTAGES
1. The loaded light vehicles can be easily.
2. Checking and cleaning are easy, because of the main parts are screwed.
3. Handling is easy
4. No Manual power
5. Easy to Repair.
6. Replacement of parts are easy
DISADVANTAGES
 Cost of the equipment is high when compared to ordinary hand jack.
 This system requires high maintenances care when compared to
ordinary hand jack.
 Care must be taken for the handling the equipment such as proper
wiring connection, Air leakage checkup, etc.
APPLICATIONS

3. 1. It is very much useful in auto-garage. This Quick Lifting Pneumatic jack is used
for lifting the vehicles.
2. Thus it can be useful for the following types of vehicles;
• Maruti,
• Ambassador,
• Fiat,
• Mahindra
