I think the real question is what the wheel looks like. Everything else should be easy to DIY, but I'd probably need to find and purchase a small-radius wheel that works well on a steel rail.
Thanks. I guessed that there was two pulleys with one side each; machined down and both sides facing each other, plus the third "wheel" on the end of the rod.
The announcer said "three wheels", the photo is blurry, IDK.
It said it’s three wheels. Probably one that sits on top of the rail and one on each side (facing inward) so it wouldn’t need the wheels themselves to be concave.
There's tons of ways to approach this idea. A wheel with a sunken face around the circumference, a tri-rail roller with wheels that grab the track from three sides, or if you wanted to be wildly simple, you could just put stiff guide guards on either side of a wheel that rolls on top of the track
It honestly sounds like a fun project. Now I'm wishing there were tracks with a notable grade near me. Oh, and free time. I'll need a pinch more of that.
Probably yes, or better look up classifieds in your city. My language has a word for this kind of a worker, but idk what it's called in English (as I haven't had an occasion to deal with them on the web).
So it sounds like three fixed furniture wheels on a 2x4, with maybe strips of wood to keep all the wheels from sliding off the track. (It seems you could do it with two?)
Pulling up on a lever brakes one of the wheels with some kind of friction pad.
The metal bar is mounted at right angle to the 2x4, and is smooth and just slides on the other rail for balance. Maybe there's a piece of pipe over the end of the metal bar? Maybe that counts as one of the wheels?
They all look identical, so they're probably not homemade.
