Abstract: In usually unload materials from vehicle is

consider as the various pneumatic cylinder act to

powered operation to tipper backside in one direction.

That conditions blockage problem in work area is

limited. To overcome can be used as pneumatic cylinder

as multi directional dumper. Our review is focus as

several gears in automobile and exposed the fact some

complicated method adopted in trailer. The trailer has

been loaded one direction. It is difficult to handle. From

our research we can decided to rectified that problem by

design and analysis of suitable operation condition.

Keywords: Pneumatic, Trailer in three axes, Direction

control

1. Introduction

This project is one of the most applicable field consider

as civil in construction work. In that period material will

be supplied by using suitable vehicles and also unload

that. The dumber is one of the carries materials which

required from site. Here the main problem happed. That

can be avoided through proper arrangement. Now a days

most of the dumper is used for one direction. Our

research developed to unloaded process multi direction. It

can be achieved by Multi directional dumper. From this

development has been obtained the benefit space

requirement.

In all the developing country focus to improve

the product in space comfortable, multi application,

easily handled as well as most important cost factor.

Those factors are considered to develop our research

work. And also it will give best efficiency.

2. Literature Review

Initial stage of a dump truck utilized to drag and abandon

material was than the existing horses body style cart. It

had been consisted of the center gravity two wheeled cart

hinged axle. This is just behind the axle when loaded

condition. After that 1900, the four wheeler vehicles

developed through the loading and unloading of the

material due to some more application. That kind of

development consider to growth of construction to time

consumption, user friendly, multiple direction

application.

The most primitive truck version mounted dump

body relied by the philosophy of dumping gravity. The

time need to lock in place to activate the dump pivoted

center had been off. After that releasing the lock the

dump rear will be activating. The loaded condition soud

be provided activate the dump operation in center of

gravity. In 1904 the first Mann gravity dump was

designed and build in England. The hydraulic dump body

was developed by Alley & Mclellan of Glasgow in 1907.

It was driven by means of steam power.

In the further researcher focus to developed the

dump truck unloading condition in the way of driving

force, control, special accessories, etc.

3. Selection of Material

The selection of material is one of the most importance

processes. It should be consider the application of

product, efficiency, environment, and also cost. So, we

had been selected the materials most suspiciously. Fig 1

shows that the Iron carbon relation related with

temperature its one of the most considerable factor.

3.1 Mild steel

Mild is one of the costs effective material considers to

other once. May be it replaced to steel application to

avoid the corrosion. It contained the maximum amount of

carbon nearly 0.29% and also can be added typically

magnetized. Due to improve the correction resistance

may be add to painted in surface or any other post

treatment process if any required. The application of mild

is improve day by day like automobile \ chassis,

cookware and motor cycle frame etc.

3.2 Chemical properties

Usually mild steel contained 0.4% of carbon in the steel.

The 1080 steel is a common type of mild steel. It’s

having 0.5% sulphur. From the varying properties of mild

steel we can get various corrosion resistance and

strength.

3.3 Physical properties

Mild steel has most strong material due to low carbon

contained. It has more resistance capacity and strength.

For that we can avoid the breakage. And also it’s having

high impact strength and tensile strength.

4. Major Parts

The Many more parts used to operating the dumper in

successive way. The common main parts are.

� Flow control valve

� Air compressor

� Direction Control Valve

� Cylinder

4.1 Pneumatic Cylinder

Figure 2. Pneumatic cylinder

Fig 2 show that the Common pneumatic cylinder

construction. Normally pneumatic cylinder can be

operated by compressor air. It’s comes from the

compressor. Cylinder used to convert the pressure energy

to mechanical energy. That mechanical energy used to

dumper operation.

4.1.1 Types of pneumatic cylinders

Commonly the cylinder based on acting source can be

classified in two types. That are Single acting and Double

acting cylinder.

4.1.2 Single Acting Cylinders

The single acting cylinder used to compressed air acting

on the cylinder in only one side. So that the pressure

energy used to to extraction stroke only. Can e obtained

the return stroke by using suitable spring energy. The Fig

3 Shows that simple construction diagram of sigle acting

cylinder.

Figure 3. Single acting cylinder

4.1.3 Double Acting Cylinders

In Double acting cylinder the compressed air is used to

both end side of cylinder. So that the pressure energy

from compressor will be used to both extract and retract

stroke. The Fig 4 is shows that the construction of double

acting cylinder.

Figure 4. Double acting cylinder

4.4 Compressor

The compressor is used to generate pressure energy by

means of compress the air on the cylinder. The Fig 5

Shows that the classification compressor.

4.5 Direction control valve

This valve is commonly used to control the direction of

source to receiver. Here we used to direction control of

compressed air. It can be classified by the application

such that 2/3, 3/2,4/3 etc. The fig 6 shows that the

construction of Direction control valve.

4.6 Flow control valves

It is used to control the flow rate of the supply

pressurized air. Fig 7 shows that the construction of flow

control valve.

5. Design and Optimization

The arrangement of pneumatic system is as per Fig 8.

Our research is based to resolve the unloaded the material

is effectively manner as the degree of freedom in the

condition of any direction. For that we have analysed to

apply in most of various area like automobile,

construction, agriculture etc.

6. Conclusion

The development of our project can be used to the

various applications in effective manner. The

compressor, direction control valve, flow control valve of

the system is most control variable of output manner. So

we can get effective output by means of control of

variables.
