lift up bridges

[rs2mike]

I am planning a whole room layout.  i am thinking of a lift up bridge or lift out bridge to span the door to my workshop..  Problem is that i do not how to design one.  if you could post plans and or pics of your lift up or out section i would appreciate it.

That is exactly what i was looking for but could not find in the search.  thank you  very much

I have a 4 foot swing gate on my around the garage layout.  Because of the size, It uses 2 door hinges.

I took these during the construction of it:

The light colored track that runs around the front edge of the layout is a subway which is actually below ground but open to the front.

I knew that I had that article, thanks for the post. I studied that thing for days,  now I'm in need of one. Who would have known.

Looks great does it swing all he way back.  How well does it carry the electricty?  how does it get electricity?

The yellow rectangles shown are hinged, swing down boards on which my wiring connectors are mounted.

Track power on the gate is connected to the track in the usual way, and connected to the power bus via a loop of wire that hangs near the hinges.  The loop is loose enough that it is not stressed or flexed much by the movement of the gate.

The gate opens about 130 degrees into the interior.  It's movement is only constrained by physical obstructions.  It is longer than the benchwork on which it hangs. 

When open, it hangs only on the hinges.  When closed both ends are supported by 2x4s on the fixed benchwork.  It is very solid when closed and latched.

thanks for the great info.  This will be very useful when it comes time to build that section of the layout.

I am modeling a masonry causeway to an island seaport that is well over a mile long.  My selective compression is on a 7 foot section that I hope I will be able to duck under for access during operational setup, and roll out of the way for more normal room access.

Plan:

Uncompleted causeway section:

Nice plan..What scale?

Nice plan, you just gave me a great idea on how to senic the span across the door.

thanks

Hudson asked: what scale?  It's N scale.

Here is an earlier photo with legless benchwork sections on garage floor.  I found that if I made the entire length I want to open all in one moveable causeway section, the section will be too big to move anywhere out of the way.  I reduced the planned length of the causeway and added a 20" long "land" section I guess I could call the hanging section or suspended section.  (The causeway section will need to be all one piece because it will have poured water simulation and I can't have a break.)  The hanging section will have no legs, will be supported between the rollaway causeway section which has legs and rollers, and a fixed nonmoving rest of the layout.

I mocked up the appearance of the land end of the causeway with an amusement district neighborhood, using a few buildings I plan to use, some IHC Victorians I got cheap and builtup which i plan to unbuild and rebuild, and some boxes and mockup cutouts.  Roller coaster mockup in the back corner, and half-built nightclub pleasure pier alongside the causeway.  Going very slow with schoolwork and evicted in-law camped out in the trainroom.

I''ve a lift up bridge. More at my room-site.

 

I've built it as part of the track and cut the roadbed later. Why? It is at grade to the right, different grad.

This is a very simple swing up. Is powered from hinged end. Is best to not build on a grade, account of loose rolling stock..John

Mike,

You need to check out my benchwork book someday.  It has a chapter on gates and lift sections.

I toured a two rail O Scale layout during a convention sometime - San Jose 2000 I believe - and the brass hat had a bascule bridge crossing the entrance to his layout room with a foot wide waterway underneath. The bridge - and waterway - was about 36 inches wide. Entering the layout room the bascule was raised until the bridge itself was kept open by the weight of the counterbalances just like the real McCoy; the waterway hinged out of the aisleway by rotating it until it was completely hidden beneath the layout platform.

This 36 inch width would scale down to a hair less than eleven inches in N Scale; figuring on an N Scale bascule bridge crossing a 24 inch wide aisle would equate to an 80 inch structure in O Scale and that's a might big structure. I am now getting closer to 70 than 65 and I shy away from duckunders; were I to need access to an operating/maintenance pit I think I would like to go the route this two-rail O Scale gentleman had gone. This construction had undoubtedly been a heckuva lot of work but the scenic effect was absolutely awesome!
