David Millson Transportation
Final Fall Presentation
Daniel Sturnick
Chris Abbot-Koch
Lance Nichols
Our client Mr. Milson needs a safe and reliable means of
transportation from his house to his pond. Due to a medical
condition he is no longer able to access his pond under his own
power. The pond is located roughly 300 feet in the linear direction
and has a 200 foot vertical drop in elevation. There are obstacles
such as wetland and rough terrain standing in the way as well.

300 +/- 50 ft
Back to the Drawing Board…
After meeting with our host David Millson…
• Our tram proposal didn’t quite capture
Dave’s creative mind.
• David really liked the idea of aerial
transportation
• We are happy to oblige!
Cable Cart
• Great means of aerial transportation.
• Point to Point means of transportation
• Fulfills Dave’s desire to be airborne while traveling to and
from his pond
• Minimal amounts of material
Cable Cart
• In our new design, we’ve incorporated the house and porch to provide
means of support
• Direct entrance to car from porch.
• Forward/Reverse/Stop capabilities
• Controls on board, at the top and bottom landings.
• Middle Support?

•
Length: 4’, Width: 3’(Handicap accessible standard), Height: 3’
Collapsible front and rear door that turns into on/off ramp
Personalized Cup Holder?
Transparent sides and bottom
Electric Winch With
Worm-Gear Drive Mechanism
• Large speed reduction ratio
• Self-locking, the gear cannot reverse
drive the worm
•Good for low horsepower applications
•Low cost
•High output torque in a small package
Safety Features
• Added risk to being in the air
• In the event of a failure:
– Power Failure: Back-up Battery Power Supply
• Automatic Charging Feature
– Mechanical Failure: Alternate cable engaged to
cart, electrical/mechanical breaking winch safely
lowers him to bottom.
Moving Forward
• DesignInspection
– Cart design must meet ANSI standards for what is
classified as “people movers.”
– Need text/pdf for ANSI A17: Safety Code for
Elevators and Escalators
• Finalize Cart Lift Installation  Inspection
– Licensed Contractor Hired For Installation
– Final “people mover” Certification
Engineering Problems Anticipated
• Budget
– David’s original budget was set between $30,00035,000
– Anything less would be greatly appreciated
Engineering Problem
• Winter is here to stay…
• No work will be able to be done on Dave’s
property until the ground is no longer frozen.
• Where will heavy machinery be able to access
his property?
• Stress analysis’ on cables + car
– Need to factor cross winds and cart rotation
(Personal Concern)
– Is an intermediate support structure needed?
