Pushing the Bridge down

[MrForbes]

Unless you use a clever linkage.

Look at the legs on a folding table.

But you want it to retract, why would you want it to lock?

My team has been prototyping and I am working on a final CAD for a non ramp solution that forces the bridge down using a combination of passive power from the drive-train, surgical tubing, and a single window motor. We looked at other methods and decided that instead of figuring out a method of generating tons of torque on an arm (both heavy and unreliable depending on implementation) we would instead focus on using our drive-train to push the ramp down, I would definitely recommend something similar.

It does't need to lock to use that linkage principle..

Why is it that we always have similar ideas on one item each year?

Great minds think alike.
ps I believe we are thinking of something similar as well.
