The motor on that door had such a high gear reduction I think it would

The Harley was close to 900lbs and it lifted it off the back of my
truck
like it wasn't even there.

If I remember correctly it took about 3 minutes for the folding hanger
door to open halfway.




I can't believe the door didn't fold in half.


It did.


I meant horizontally - from the weight.


No way. The "garage" was actually a 32' by 46' aircraft hanger that one
of the properties we had in Florida had. The door was about 28' feet
wide and 16 feet high. It folded in half horizontally as it was raised.

It had a very heavy duty frame (probably for hurricane codes) made of
square 4" by 4" steel tubing that ran horizontally and vertically every
four feet or so. Lifting a 900lb motorcycle was duck soup for it to
handle. The electric motor didn't even change pitch when lifting it due
to the high gear reduction.

During one of the hurricanes (we were not there) about 24 people who
lived in the gated community all moved into the hanger during the worst
of the storm because it was totally brick construction (other than the
door). From the stories I've heard they had quite a hurricane party in
it with generators sitting outside providing power.
