Build Details:
|
Snowmobile shaft cut in half with the drive sprockets and bearings. The ends were milled down to 7/8" to fit the bearings and the drive sprockets. |
 |
| Start to the bearing mount and end plates in 1"x2" steel |  |
| Track adjuster parts made with 2"x2" Rec tube, angle iron and some scrap round tube |  |
| Track adjuster in the 2"x2" Rec tube |  |
| Wheels installed every 12 inches |  |
| Track installed. Track was just a used track from a snowmobile cut in half. |  |
| Dimensions are approx. 3.5ft W x 4ft L |  |
|
Needed to be able to adjust the motor position to tighten the chain so came up with this mount setup |
 |
| The wheel chair motors have a 300 pound capacity |  |
| All mocked up and test fitted |  |
| Tested with this gear ratio but it was way too slow. Plenty torque not enough speed |  |
|
Mounted the deck from a garden cart. The cart was rated to carry approx. 1400 pound from Tractor Supply. I was able to reuse the battery boxes from the chair they fit perfectly under the two center deck cross bars. |
 |
|
Capped all the ends and a fresh coat of paint |
 |
|
Added a small winch from Harbor Freight. |
 |
|
Finished off the electronics box. Used the original charging port from the wheel chair. 100 amp key switch and the bottom display shows battery voltage. |
 |
|
The roller wheels for the lift are actually metal casters from tractor supply. |
 |
| The actuator is slow but rated to lift 1200 pounds. |  |
 |
|
| The platform was modified to mount the top rollers on the back underside allowing the lift motion |  |
| The front mounts of the lift bar are stationary. |  |
| Using the lift as a working table with the sides on it. I did have to push out the light bar and winch to clear the lift actuator. |  |
