SEEDDavid Millson Transportation

Final Fall Presentation

Daniel SturnickChris 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?

Cart Design 1

• Length: 5’ Width: 4’ Height: 3’• Door opens to be 29” wide •Metal frame: 2” thick Aluminum Square Stock

Cart Design 2

• 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

• DesignInspection– 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 $30,000-

35,000– 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?

Questions?
