3. PART ONE
Introduction to Bishoftu Automotive Manufacturing
Industry
 Bishoftu automotive manufacturing industry was first
established in 1984E.C, and has been part of METEC
and now it is under Ethio-Engineering Group.
 It have different sectors: namely,
 Design and Development
 Power Train
 Vehicle Production Factory
 Tank Production Factory
 Body and Frame Production Factory and more.

4.  Main products and service
 Maintenance and supply of frames of
vehicles
 Supply and maintenance of
construction machineries, heavy duty
buses and trucks
 Supply and maintenance of light
vehicles.

6. PART TWO
OVERALL INTERNSHIP EXPERIENCE
 Section of the company we have been
working in
 Garage
 Power train
 Light duty vehicle production

7.  Work tasks that we have been practicing
on
 Light and heavy duty car maintenance
 This work has many steps with the special tools and
specification, which includes
engine assembling, disassembling and inspection
 checking tires, shafts, gearboxes and replace those
damaged and worn parts
 lubricate all parts with gear box oil before installation
 wheel alignment
 optimize the vehicle's driving characteristics, and
minimize possible tire wear, the front wheels must be
aligned at previously calculated angles.

8.  Other services
 perform annual service according to the
manufacturer check list
 perform basic service according to the
manufacturer check list
 replace wiper washer reservoir
 remove and replace friction plates and
installing gear box on the truck
 remove the clutch servo
 install the clutch servo

9.  Challenges observed during the internship
 Long working hours
 No working clothes and other supports are given
for us in the company
 Low number of customers

10. PART THREE
PROJECT SELECTED AND WORKED OUT
 Project title: Design of hydraulically operated tire and
brake drum handler
 Short summary of the project
 The usual way of removing brake drum and tire is
done manually by lever and using other metals which
needs more time and more man power
 Decrease time consumption of workers so benefit to
the company. Almost every vehicle needs tire
servicing and brake lining which need removal of tire
as well as brake drum.
 So hydraulically operated tire and brake drum handler
is designed to modify the way a tire and brake drum is
removed and installed.

machine

12.  Problem statement and justification
 The problem we observe in the company includes
the use of high human labor to remove and install
tire and brake drum.
 So the project discusses on the design of tire and
brake drum handler which operates hydraulically.
 The main problems are:-
 Requires more time to execute the operation
 It needs high man power to remove and install
 It needs high safety to execute the operation
12

13.  Objective of the Project
 Main objective:
 Design of tire and brake drum handler
 Specific objectives:
 Reduce time needed for the operation
 Reduce man power needed
 Increasing the productivity of the operation
 Protecting the quality of the product
13

14.  Methodology
 When we design the tire and brake drum we
followed the following methods:
 Collect data for the project from different sources
 Identify the possible mechanisms
 Select the proper material for each part
 Do each part design calculation
 Take the result and decision
 Draw a detail drawing of each part
 Draw assembly drawing of the machine
 Doing the cost estimation
 Give conclusion about design

16.  Design Considerations
 Operating Pressure = 30MPa
 Total Load = 0.071ton = 710N
 Maximum lifting height of the ram =
30mm
 Total number of stroke needed = 15times
 Human force applied = 30N

27.  Working principle
 First fill the oil into the reservoir of the hydraulic bottle
jack
 Push the machine to the car that need wheel service
 Pump the hydraulic bottle jack using lever up to
required height of brake drum or the lifted height of
the vehicle intended for
 Insert the brake drum of the vehicle to the support
curve or place the tire on tire handler frame base
 Tighten the drum using bolts or chain through the hole
prepared or tighten the tire to the handler using chain
if needed
 Pull the machine to the specified position
 After finishing the servicing again push the machine to
the vehicle
 Finally install the brake drum or the tire to the vehicle.

29.  Conclusion
 Tire and brake drum handling machine is designed
to remove and install a tire brake drum of vehicles
 It is special solution for the company to remove
and install the brake drum of car easily
 It saves man power and time to execute
 It has high safety
 It has high lifting ability than curved metal
 Its cost is not expensive
29

30.  Recommendation
 We recommend the company that this
hydraulically operated tire and drum brake
handler is a total benefit for all bodies
involved when performing the operation,
so we recommend to manufacture the
project and use the product.
