ABSTRACT
Hydraulic jack system is attached to automobile vehicle on front and rear part of the chassis. An automobile
hydraulic jack system can be easily attached to all currently manufacture automobile chassis and frames. There
is a front suspension hydraulic jack that is mounted centrally to the front suspension of an automobile between
its front wheels. There is also a rear suspension hydraulic jack that is mounted centrally to the rear suspension of
the automobile between its rear wheels. The system operates from a compressed fluid reservoir tank that has
connections for the front and rear car jack outlets. Additional outlets can be added to the compressed fluid
reservoir tank for connecting a hydraulic lug wrench and another for a tire inflating hose. The Major Project
entitled “Mechanism of sliding hydraulic jack for heavy vehicles in automobile” Worked on the principal of
hydraulic power and operated by 12 Volt DC current, solves the all major problem of maintenance of all
automobiles specially the heavy vehicles like truck and bus. This work, if implemented, would definitely help in
the maintenance of automobiles and also in saving of time.
Keywords:Light moving vehicles, integrated automated jack, Hydraulic pump, Chassis.

1.DESIGN OF HYDRULIC JACK
Hydraulic basics:
Hydraulics is the science of transmitting force /or motion through the medium of a co nfined liquid. In a hydraulic
device, power is transmitted by pushing on a confined liquid. The transfer of energy takes place because a quantity
of liquid is subject to pressure. To operate liquid-powered systems, the operator should have knowledge of the basic
nature of liquids.
1.1 Hydraulic system
A hydraulic jack uses a fluid, which is incompressible, that is forced into a cylinder by a pump plunger. Oil is used
since it is self-lubricating and stable. When the plunger pulls back, it draws oil out of the reservoir through a suction
check valve into the pump chamber. When the plunger moves forward, it pushes the oil through a discharge check
valve into the cylinder. The suction valve ball is within the chamber and opens with each draw of the plunger. The
discharge valve ball is outside the chamber and opens when the oil is pushed into the cylinder. At this point the
suction ball within the chamber is forced shut and oil pressure builds in cylinder.

Hydraulic Fluids
Hydraulic fluids are a large group of fluids used as the motive medium in hydraulic machinery. Fluid types include
synthetic compounds, mineral oil, water, and water-based mixtures. The fluids are found in machinery and
equipment ranging from brakes, power steering systems, and transmissions to backhoes, excavators, garbage trucks
and industrial shredders. Hydraulic systems are very common in aircraft flight control systems. Hydraulic fluids can
contain a wide range of chemical compounds, including: oils, butanol, esters (e.g. phthalates, like DEHP, and
abdicate, like bis (2- ethylhexyl) adipate), polyalkylene glycols (PAG), phosphate esters (e.g. tributylphosphate),
silicones, alkylated aromatic hydrocarbons, polyalphaolefins (PAO) (e.g. polyisobutenes), corrosion inhibitors, etc...
2. HYDRAULIC CYLINDER AND OTHER ELEMENT WITH WORKING
A Hydraulic cylinder (also called a linear hydraulic motor) is a mechanical actuator that is used to give a linear force
through a linear stroke. It has many applications, notably in engineering vehicles.
1) Ram Cylinder: It is a cylinder in which produces a slide way to the ram. The ram cylinder is made up of mild
steel with density of 7.868 gm/cc. It is mounted on the base plate.
2) Plunger cylinder: The plunger cylinder is made up of mild steel and is mounted on the base plate. It provides slide
way to the plunger in order to build up the pressure.
3) Plunger: Plunger is made up of mild steel which reciprocates in plunger cylinder to inc rease the pressure of the
oil.
Case 1: when front wheel of the vehicle gets punctured
In the case of front of the vehicle gets punctured, we lift wheel using the switch which provide the connection to the
hydraulic pump system .when we operate the front wheel switch, hydraulic pump system takes drive from the
propeller shaft of the vehicle and hydraulic pump produce the high pressure energy. Hydraulic fluid in hydraulic
pump system at high pressure moves to the front wheel jack through the hose pipe and lift front wheel of the jack.

In the case of rear of the vehicle gets punctured, we lift wheel using the switch which provide the
connection to the hydraulic pump system .when we operate the rear wheel switch, hydraulic pump system takes
drive from the propeller shaft of the vehicle and hydraulic pump produce the high pressure energy. Hydraulic fluid
in hydraulic pump system at high pressure moves to the rear wheel jack through the hose pipe and lift rear wheel of
the jack.
Specification of Hydraulic Jack

2) Jack dimensions
3) Lifting range in-cm
4) Oil capacity in-cc
5) Net weight in-kg
I. Hydraulic cylinder is the most important component in hydraulic systems, it will transfer hydraulic energy into
mechanical energy, and is matched with various transmission mechanism, to complete a variety of mechanical
motion.
II. . Hydraulic cylinder has the advantages of simple structure, large output force, stable and reliable performance,
easy maintenance, wide application.
III. Hydraulic support lifting jack is the main weight-bearing element which undertakes the movement of the
hydraulic support and each part. The product is mostly single telescopic, double -act, piston type hydraulic cylinder,
widely used in the hydraulic support for traction, side thrust, protection and assistance, balance, support adjustment,
and etc.

Principal of operation
Both hydraulic jacks are pivoted on the rectangular struts. The one end of jack is fixed to frame. The rectangular
Struts are kept hollow for reducing the weight. The rectangular paddles are also pivoted on the other end of struts.
Hydraulic jacks are operated by 12 volt DC battery. At a single time, one and two both jacks can work and vehicle
can lift from one side and also from two sides as per the requirement.
Scope for future work
The arrangement of hydraulic jack system is designed for heavy loaded trucks in this project work, but this
arrangement can be widely use in future for heavy vehicles also by making some small modifications in current
project.

The main aim of this project is to implementation of hydraulic jack to a heavy vehicles, due to these heavy loads on
a vehicles the life the tyre will be reduced. Whenever the vehicles is static condition the vehicles exerts point load on
tyre due to this load the wear of the tyre takes place. So that the present of hydraulic jack increases the life of the
tyre and also it helps in reduction of transportation cost. And also it helps the user for changing of tyres whenever
they were busted or punctured. Hydraulic jack system is attached to automobile vehicle on front and rear part of the
chassis. An automobile hydraulic jack system can be easily attached to all currently manufacture automobile chassis
and frames. There is a front suspension hydraulic jack that is mounted centrally to the front suspension of an
automobile between its front wheels. There is also a rear suspension hydraulic jack that is mounted centrally to the
rear suspension of the automobile between its rear wheels. The system operates from a compressed fluid reservoir
tank that has connections for the front and rear car jack outlets. Additional outlets can be added to the compressed
fluid reservoir tank for connecting a hydraulic lug wrench and another for a tire inflating hose.
