hangar doors

[Tater]

just from a non-pilots angle, whats the reason for the hangar doors to
be the way they are? I mean the 2 part folding types. Is there some
advantage to them? why dont we make car garages the same way?

I've seen all sorts of hangar door designs. If you're talking about a door
that has a horizontal hinge half-way up, and which rises vertically on
tracks, folding in half lengthwise as it does so, then a) this design is
simple and allows for maximal use of the space within the hangar (ie doesn't
consume vertical room within the hangar), and b) there *are* car garages
designed the same way (just as there are hangar doors designed in other
ways).

The main advantage of a bi-fold door is that the header of the door and the
vertical steal beams on each side of the door opening support the door when
it is raised, this makes abnormally wide doors without tracks or track
extensions possible. I think the motor, gearbox, cables, steal header and
beams would make it rather cost prohibitive when compared to a traditional
overhead type garage door which, due to it's light weight can be suspended
from the underside of roof trusses when raised.

The Bi-fold also has no tracks to fill and freeze in the winter, and it makes a good canopy when it is raining...

You do, however, have to inspect the cables regularly to make sure that
they are not fraying. Racing driver Mark Martin almost lost his Citation
when the cables broke just after he had wheeled the jet into his hangar.

Caution, boys and girls.

It has been a few months since the last Tater sighting, but if you remember,
this one has the characteristic makings of trolldom; do you really want to go
down this road again, with one already consuming and dominating the discussions?

It's up to you. Answer at your own risk.

No, I don't remember. Perhaps you could refresh our collective memory?

Checking Google, I found only 19 posts *total* from that individual in this
newsgroup. I admit, I did not read every single one, but I skimmed the
excerpts in Google, and read about a half-dozen of the ones that seemed most
promisingly troll-like, and found nothing that I could classify as trollish
behavior.

Are you sure you've got the right guy? He hasn't started many threads, he
doesn't appear to post all that many articles, and what he does post seems
just about as relevant as anything the rest of us posts (maybe even more so
in some cases :) ). Just how much of a troll could he possibly be?

The apparently it doesn't rain hard enough up where you're at... Down here
in Texas, I can get wet standing at the back of my hangar if I have the door
all the way up... When we get some good storms coming through here, the rain
comes down nearly sideways...

In a previous hangar, one of the cables came loose and the door dropped...
Jumped the track and swung inwards... I had my boat parked in from of my
wing and I was crossing behind the boat... It pushed the boat backwards and
the swim platform pinned me against the wall... When they fall, they make a
pretty damn loud sound though... I've decided that if I ever build my own
hangar, I'm going to go with the sliding multi-fold fiberglass panel doors
instead... They are light enough that you don't need a motorized opener, so
they're perfect if you ever lose power and still want to go flying...
They're translucent, so they let a lot of light in also...

Well, I did say raining, not Texas raining. Of course rains harder there. Probably have rain drops the size of a
swimming pool! ;-)

I watch the cables and they look fine. The latest doors are using nylon straps which looks pretty good...

Good point about the power issue. I have wondered what I would do to open the door if the power was out...

[Robert Dorsey]

My hanger has sliding doors. When I arrive at the airport, if one of
my next door hanger neighbors has his doors open I have to wait until
he closes one of them to get my plane in / out.

And of course, some hangars (such as the one my airplane is in) have
half-width sliding doors. It's a T-hangar, and the back of the hangar is
exactly half the width of the front. When you open the doors, the two
halves of the sliding doors come to rest over each other at the back of the
opposing T-hangar, avoiding blocking anyone *and* avoiding consuming any
space within the hangar.

Yeah, the nylon strap systems seem a lot more sturdy than the ones on the
hangar I'm renting... My hangar has the electric motor and winch mounted
inside the hangar back towards the 'T' and quite a few pullies and cables to
make everything hopefully line up right... It creaks and groans during the
opening and closing process... The systems with the motor driving a common
shaft that runs the width of the door near the bottom of the door seem
considerably simplier and less prone to problems...

Well, I have refrigerator in my hangar and it is stocked with beer and
Cokes... I think it would be time to switch from drinking Cokes to drinking
beer and just wait for the power to come back on... If I was really
desperate, I guess I could go get a generator and power the motor and
winch... Kind of depends upon whether I was going flying or coming back, I
guess...

[nrp]

A lot of cable driven systems have limited life because the pulleys and
drums are too small. There should be cable thimbles etc wherever the
cable attaches to something to prevent the local forces or motions from
crushing or abrading the cable. I have heard of a person being killed
by a falling hangar door.

and a few posts on some of the other aviation groups. yes, I admit that
my post at times do look trollish, but I suppose that could come from
the frustrations of trying to find infor with google (and gettting
1,000,000 results to wade through)

heh, thanks. My intent is not to troll, but sometimes I get fed up with
pilots complaining about the loss of airfields and the dwindling
numbers of GA then mention that they spent a kilobuck on upgrading to
glass cockpit.

I believe Morgan was one of the people who think that only people with
lots of money to throw away should be pilots, then gripes that yet
another GA airport gets closed down.

Talk about remembering the wrong guy!!!

Not me. Not even close.

I remembers saying tader shouldn't to one of your posts. Something about
wanting to fly in an airplane with a windup rubber-band, or something cheeeeep
like that. You whimper about wanting to fly without any money at alllll.
