Deber Birhan, Ethiopia
Chapter 1 Introduction and Background of the Company
1.1 introduction
The machinery engineering industry found in Debre birhan. The construction
machinery industry is one of the most famous and hugs company. This company
have a great role for working heavy machinery with repairing standard and
modernizing specification of the parts of all heavy load machines and also have
some light vehicles that helps for local transport. In the company there are 1000
workers. but due to shortage of raw material the company was stopped the
production.

1.3 Brief history of the company
By a letter issued from Ministry of Defense of the federal democratic republic of Ethiopia on
March 15, 2007G.C it was decided that the industry shall be structured independently by the
name "DEFENCE INDUSTRY SECTOR" It had been leading sixteen military Engineering
complexes and development enterprises. And after the decision of the federal democratic
republic of Ethiopian government, the Ethio engineering group has been established by the
council of Ministers Regulation No.183/2010, since June 09, 2010, and Ethio engineering group
is changing the name from Metals and engineering corporation (METEC) took over
all responsibilities from defense industry sector.
1.4 raw material used by case company
raw materials used in manufacturing loaders, which are heavy equipment machines used in construction
and mining, we typically see a variety of materials being utilized. Here are some common raw materials
you would find in the production of loaders:
1. Steel:
- Frame: Loaders have sturdy frames made of steel to provide structural strength and support for the entire
machine.
- Bucket: The bucket, used for scooping up materials, is often made of steel to withstand tough working
conditions.
2. Rubber: - Tires: Loaders typically have large rubber tires to provide traction and mobility on various
terrains
3. Engine Components; - Aluminum, Copper, Steel: The engine components are often made from a
combination of materials such as aluminum, copper, and steel to ensure durability and efficiency.
4. Hydraulic Components; - Steel, Rubber: Hydraulic systems in loaders require components made of
steel for durability and rubber for sealing and flexibility.
5. Glass: - Windshield: Loaders have a windshield made of safety glass to protect the operator from
debris and environmental elements.
6. Plastics: - Dashboard Components: Certain parts of the loader's interior may be made of plastic for
lightweight and cost-effective construction.
1.5 organizational structure of case company
As we know there are four organizational structures in our context among that the
case company follows line organizational structure.so the structure and detail
analysis follow as below
Production process
Order Processing: The production process starts with receiving a customer order or
forecasting production based on market demand.
• Design and Engineering: The product design phase includes specifications,
blueprints, and detailed planning.
• Component Manufacturing: Some components are manufactured in-house,
while others are outsourced. single-source philosophy means a large portion of the
components are made internally.
• Assembly: The various components are assembled on the production floor.
• Testing and Inspection: Rigorous testing and inspection procedures ensure that
the machine meets quality and performance standards.
• Packaging and Shipping: Machines are prepared for safe transport and are
shipped to customers.
• Installation and Training: may provide installation services and training for
operators at the customer’s facility.
Customers and competitors
1.6 customers of the case company
The customer of Ethio engineering group is any group of contraction the main are sunshine
construction, sur construction, Rama Construction and different construction group.
1.7 competitors of the case company
The competitor of Ethio engineering group is the only competitor in Ethiopia are Zama Ethiopia
Trading plc.

Maintenance engineering management practice
2.1 type of machinery and equipment safeguarding and tools
Are essential to protect operators from potential hazards such as rotating parts,
flying debris, and unintended machine movements. These safety measures include
physical guards, interlocking devices, emergency stops, and personal protective
equipment (PPE).
1. Lathe Machine Safeguarding Tools
Fixed Guards: Covers rotating parts like chucks and lead screws.
Interlocked Guards: Prevent machine operation if opened.
Adjustable Guards: Shields that adjust to different workpieces.
Trip Bars and Presence-Sensing Devices: Stops the machine if an operator gets too
close.
Emergency Stop (E-Stop) Button: Allows immediate shutdown.
Face Shields & Safety Glasses: Protects against flying metal chips.
2. CNC Machine Safeguarding Tools
Enclosed Guards: Fully enclosed cabins prevent flying debris and coolant
exposure.
Interlocking Doors: Machine stops if the door is opened.
Pressure-Sensitive Mats: Stops the machine if stepped on.
Light Curtains: Detects movement and stops operation.
Emergency Stop System: Ensures quick shutdown in case of malfunction.
Automatic Chip Conveyor & Coolant System: Prevents manual handling of chips
and coolant exposure.
3. Drilling Machine Safeguarding Tools
Drill Press Guards: Covers the rotating drill bit and chuck.
Adjustable Shields: Protects hands from contact with rotating parts.
Clamps & Jigs: Prevents workpieces from slipping.
Interlocked Shields: Stops machine if the guard is moved.
Two-Hand Control System: Ensures hands are away from the drill.
Gloves (Only for Handling Workpieces, Not While Drilling): Prevents direct
contact with sharp edges.
4. Robotic Machine Safeguarding Tools
Safety Fences & Barriers: Restricts access to robotic work areas.
Light Curtains & Laser Scanners: Stops robot motion if an operator enters the area.
Pressure-Sensitive Floors: Stops the robot when stepped on.
Interlocking Gates: Prevents access while the robot is active.
Emergency Stop Buttons: Located at multiple points for quick shutdown.
Collision Sensors: Stops the robot upon detecting unexpected obstacles.
