This document summarizes the experiences and projects of a 4-month co-op with the Fleet Engineering Department of the City of Edmonton. It describes several projects completed including analyzing maintenance data for drainage trucks, designing a lifting device for transit bus seats, investigating an electrical fire in a sweeper truck, and modifying Labrie door pins. The co-op provided opportunities to apply academic knowledge to real-world situations while working with other professional engineers in more of a family setting. Diagrams and drawings are included to illustrate some of the projects.

1. AMAZING 4-MONTHS CO-OP WITH FLEET
ENGINEERING DEPARTMENT AT ELLERSLIE.
FIRST DAY MOTIVATIONAL SPEECH!
(I BELIEVE I CAN DO ALL THINGS, ONCE I
PUT MY MIND AND SOUL INTO IT (JESUS).)
YOU BECOME YOUR BEST ONCE YOU LOVE WHAT YOU DO(CHARLES JUMBO).

2. WHAT DOES IT MEAN TO BE A CO-OP ENGINEERING
STUDENT WITH THE CITY OF EDMONTON?
- It gives me an edge over other graduate student and
improve my resume.
- I never had a slight clue on what it feels like to be called
a mechanical engineer until I started working for the city
fleet department.
- Working with the city of Edmonton has provide the chance
for me to apply knowledge from academic work to real live
situations.
- Working with other professional engineers is just the best
feelings for me.
- I have my own office
- Provide an opportunity for field trips
- Working with the city is more like a family setting.

3. PROJECTS I HAVE WORKED ON WITH THE
FLEET.
- Electric Fire outbreak in sweeper Truck .
- Product evaluation for oil master 1.
- H3899 Labrie Steering Incident
- Tool Alignment for transit buses
- Reliability study for drainage vacuum/eductor truck
- Designing a lifting devices for transit driver seat.
- Modification of labrie door pin.

4. ELECTRICAL FIRE OUTBREAK
Recommendations:
Base on previous and
recent invent on electric
fire outbreak, Fleet
Engineering should carry
out a campaign for:
Enforce a proper wiring of
electric wire to avoid
contact with each other.
Apply the use of fuse or
circuit breakers were
appropriate.
Wires that are close to
the exhaust system
should be properly

5. RELIABILITY STUDY FOR DRAINAGE
Responsibility as a Reliability Co-op engineering student:
• Analysis of maintenance history and failure data to prioritize issues
and opportunities
• Develop preventative and predictive maintenance strategies
• Perform Root Cause Failure Analysis investigations
• Conduct equipment assessments to understand life expectancy
• Develop and support long-term maintenance plan and asset
management goals

7. DESIGNING A LIFTING DEVICES FOR TRANSIT
BUS SEAT.
2 Need/Goal Statement
Need: The technicians in The City of Edmonton fleet garage are
presently lifting the driver seat in the transit buses by fastening the
seat belt and then pulling the fastened seat belt with a boom.
Goal: design a device that will help in lifting this seat, without using the
driver seat belt. The devices will serve as an attachment to pick up
the seat.
3 Objectives/Constraints and Rationale
In this section will address the initially proposed objectives and
constraints for the project; as well as identifying the rationale
behind each of these choices. Here are the outline the objectives in
detail individually; a summary chart is provided first (Table 1), in
order to clearly outline the objectives in brief.

9. DESIGNING A LIFTING DEVICES FOR TRANSIT
BUS SEAT
Objectives Description
Safety Must not endanger the client during operation.
Size Target width is about 16 inches by 6 inches tall and 7 inches deep.
Weight Must be light enough to be lift by hand, but heavy enough to remain
stable.
Cost The lifting mechanism must not exceed $100.
Center of
gravity/design
analysis
This lifting mechanism must be pick at the center of gravity to avoid
swerving during lifting. In getting the center of gravity three different
method were applied. 1) The tipping test 2) Pivot test 3) the angle
test. Design analysis involves understand the strength of this
design. This requires application of some design principle which
are factor of safety, moment diagram, stress calculation, force
analysis.
Usability The final product will be operated by the client.
