Need Design Engineering Opinions For Motorcycle Storage Lift.

[Rcdizy]

I want to make one of these... For as low cost as possible...

I was thinking of using square 2" tubing for the stationary posts....with 2 1/2" square tubing slided over top for the piece that would move up and down with pullys and cables.



I sort of have the design in my head.
Would the square tubing be strong enough? what thickness? Or must I use I beam or different stock?
The garage is 10' ceilings and the motorcycle is 400pounds.
With the design I am thinking I may need to space it away from the wall a small amount therefor there wouldn't be mid span bracing or fastening to the wall

if I use the basic sliding tubing design, how could i keep from he paint scratching off

Is it acceptable to have 2 cables on a single winch spool

Might that not lead to trouble if one cable got under the other? The effective diameter of the shiv would be different for each cable then, and they would retrieve unequally. Just my thinking..

If you do this devise some sort of slack adjustment so the cables work under the same tension. If the lay of the cable is the same, one to wear out faster if you wind them towards each other from opposite ends of the drum.

Have a good day.

Nice job RC. The HF winch is a good idea.
