This document provides a summary of a 4-month internship and project at the Tana Beles Sugar Factory in Ethiopia. It includes sections on the background of the factory, experiences during the internship, and a project to design a simple hydraulic lifting machine. The internship provided opportunities to gain practical skills and expand theoretical knowledge of the sugar production process. A key project was designing a lifting machine that reduces the complexity and cost of traditional forklifts while maintaining a lifting capacity of 120kg.

4. 1.Background of Tana Beles Sugar Factory.
 Beles sugar factory is a project, will manufacture refinery
sugar and ethanol as a main product and other sub-
products like molasses and bagasse after finshing
instalation.
 It started in 2004 E.C. in North West part of the capital city
in Amhara region, Awi zone. It is far from around 576KM
from Addis Ababa and 3KM Jawi town of Fendika.
 It landed(covers) 21,000 care meter areas.
 The construction of the factories is being carried out by a
domestic company-Ethiopian Metal & Engineering
corporation.12,807 hectares of land is made irrigable while
13,049 hectares of land is covered with cane.

2.Its main products and services.
 Sugar cane today is considered as one of the best converters of
solar energy into biomass and sugar. It is a rich source of food
(sucrose, jaggery and syrup), fibre (cellulose), fodder (green
leaves and tops of cane plant, bagasse, and molasses and to
some extent press mud), fuel and chemical. But tana beles sugar
factory is not run yet for the future start to produce the above
listed and the following products.
raw sugar
liquid sugar
refined sugar
molasses
sugar alcohol
ethanol
electricity

6. 3. Its overall organization and work flow
 The organizational structure of Tana beles sugar factory
building project was divided in to four branches.

 Human resource: this branch was controlled all human power that found in the
project.
 Operation management: this also controlling and managing the erection and
installation up to human resource management on site.
 Logistic management: this branch also controlling and managing the objects or
goods that is finished product or unfinished product for the project and the row
material that uses for the project.

 Build up a network of professional contacts for future opportunities and
reference.
 Gaining knowledge of organizational structure and processes in the industry.
 Becoming familiar with new techniques and methods of work
 Becoming familiar with new techniques and methods of work

8. 6
In which section of the company you have been work in
 In Tana Beles sugar project there are eight /8/ sections from
these we are participated to different sections by changing one
section to other in different weeks or months, for example
 Cane handling and preparation.
 Juice extraction
 Clarification
 Process house
 Refinery
 Water treatment
 Molasses
 Power house section.
But we are mainly followed the following three sections:
- cane handling and preparation section
- juice extraction section
-Clarification section.

5. Overall Benefits Gained from the Internship.
 Improving Practical Skills
 Upgrading Of Theoretical Knowledge.
 Improving Interpersonal Communication Skills.
 Improving Team Playing Skills.
 Improving Leadership Skills.
 Understanding about Work Ethics Related Issues
 What You Gained In Terms Of Entrepreneurship Skills

11. 9
Other benefits to gain the in the internship practice are:
 we have expanded our theoretical knowledge when we ensure
practically.
 In the education time there is specific number of machines
and material equipment that bind our skill but in this
internship we have been familiar with new techniques and
methods.
 We develop a confidence how to lead different kinds of
behaviors of an employees and tasks.
 we have learnt how important is being punctual and how
behave in a company.
 we have gained knowledge how to administrate a profession
 Punctuality
 Willingness
 Tolerance
 To be hard worker

6. PROJECTS AND CONTRIBUTION
Design of simple hydraulic lifting machine
Introduction
 Simple hydraulic lifting machine is one type of power industrial
truck.
 The ultimate purpose of this machine is the same to safely allow
one person to lift and move large heavy loads with little effort.
 The design of this lifting machine should be creative, simple, user
friendly and use the minimum cost especially the material cost.

13. 11
Problem of Statement
According to the market lifting machine basically the lifting machines
nowadays are provided using the hydraulic system and other complex
system. What try to do these tasks is tried to develop lift machine that
changes this very complex part and the carrying capacity of the
hydraulic machine to reduce:
 The weight of the machine this means to reduce the complex part
 The costs of forklift are very high to compare to this simple
hydraulic lifting machine so to reduce by half.
 The emplacement of fork lift not portable because difficult to move
and not adjustable.
 Many product /lift machines/ designing in a big range of load.
 The maintenance of forklift is cost and takes time.
 The systems of other forklift are complex and difficult to
maintenance.

Objective
1 General Objective
 The importance of this project to reduce the work of forklift by

 To apply the knowledge and skill of manufacturing process.
 To modify the lift machine structure.

15. Scope and Limitations
13
The Maine limitations of this project are:-
I. This machine doesn’t work above maximum height
of 10m.
II. It doesn’t have its own motor for moment
III. It doesn’t perform its activity during night time.
Since it hasn’t electrical system.
IV. The maximum carrying capacity of this machine is
120kg but above this the machine will be damaged.
Design Specification
Maximum load=120kg
Maximum height=10m

16. Detailed Design and Description of the Project

 machinability
 Availability in standard sizes plates
 Cost
Design analysis based on:-
Bending stress
shear stress
deflection
14

17. Proper selection of the wanted component

 Displacement - Pressure
 Rpm (revolution per minute )
 Hydraulic pump selection based on:-
 System pressure requirement - Fluid compatibility
 Delivery volume requirement - Bulk and weight
 Drive speed - Noise and vibration
 Cost efficiency (including pump efficiency)
Hydraulic hose selection based on:-
 hose inside diameter
Hydraulic fluid selection based on:-
 Have superior oxygen stability - Lower pour point

18. Operation of Our Machine
 Our simple hydraulic lifting machine is a single acting cylinder hydraulic
machine.
 Exert a force in only extending direction
 Do not retract hydraulically.
 Retraction is accomplished by using gravity.
Controlling
A two-piston, three ways, manually operated gravity directional control valve
(DCV) used to control the operation of our machine. In the gravity mode, full
pump flow goes the tank via the pressure relief valve, the gravity which created
by the load to be lift pull to the ground or in down ward direction the piston as
oil from the blank end “A” drain back to the rank (tank).When the valve is
manually actuated the pump flow goes to the cylinder blank end area (A) via
DCV perpendicular directions. This extends the cylinder. At full extension,
pump flow goes to the relief valve. Deactivation of the DCV allows the
cylinder to retract as the DCV shift into gravitational mode.

CONCLUSIONS FOR DESIGN
The aim of our project is to design the simple hydraulic lifting machine
which is capable of lifting load up to 120kg at the maximum height of
10m. we accurately achieved our first goal of design to work the analysis
of all components with selection of their necessary parts like motor,
pump, hose etc and the proper selection of material for each component
of the machine. We feel that our design and fabrication will have greater
successes both in terms of strength and stiffness. These hydraulic lifting
machine uses oil to perform their own activities.

RECOMMENDATION
During the internship months we had seen some short comings in the
project which were the main cause for manufacturing delays and wastage
of resources. We have told these problems for the TANA BELES sugar
project officials who are responsible for to prevent the resource of the
company.
We recommend for the project most of the conventional machines do not
use coolant and do not seat the materials at a proper place these cause
materials cannot use a long period of time.
We also recommend our project;
Our machine does not have its own motor system so any person can
modify these by adding motor system.
Our machine also does not work in a night time so other person can
use electrical system and to use these machines for 24 hours.
Our machine maximum carrying capacity is 120kg but other person
can modify different part to increase carrying capacity
