Guys, I've been asking You few times (also using different nick about a year ago;) ) for technical details concerning the gondola transport. I wanted to thank You for that and show You the effect of my job. I was doing the gondola model between my University and the dormitories as as my engineer thesis. I needed a lot of little information and some of them I got from You. well, that's the effect. I hope, You will enjoy it a little bit. I know it's not perfect job, but I spent 6 months on doing that and now I'm just tired of working. and I got a good note for that;) there it is..

This beautiful and large VR101 - model unfortunately had been killed by a thunderstorm in 2005, the cableway was about 28 meters in length and located near Bremen, Germany.

That's most likely the most real looking model gondola I've seen before. Do people make model ski lifts?

[Petz]

Have built one little Leitner skilift (type B) some years ago, please look at about the first quarter of my page.

In the meantime i have sent the skilift to my collegue Christian near Frankfurt am Main (Germany) where it had been added to his wonderful Girak model double Chairlift, you can see this at the more lower pictures.

Those were amazing! How many hours would you estimate each one would take to make?

Many thanks for your comment. Time affort depends on the legth and the type of a lift but i have to calculate from 50 hours upwards cause excluding the motor all the parts i have to produce by myself.
I use some bend devices for the chair hanger arms and the chair sheets; even a form grinded tuning tool on the lathe is necessary to get the same form for the chairs and rope wheels surface but this makes the work only a bit faster.... .

thats about right markus.with mine i drew up everything on auto cad and made blueprints.im a machienest by trade.so producing all the parts was pretty easy.eariler this year,i switched everything over to 303 stainless steel.the station structure is all 6061 aluminum.the sheaves are a plastic called cellcon.the sheaves i sent you a while ago,do they fit your application?

I have checked them but because i use a bit different type of clamp form and wheel contouring they would not support my system exactly.
I don´t use any construction drawings, the lifts are built based on the optical impression; the clamps and sheave batteries had once been "normed" in conclusion of the lift type.

on all of my sheaves,i have a depth guage.any more than .080 of depth i remove them and throw them away.the normal groove depth is .065 depth.how deep is the groove on your sheaves?as for operating,how long does your lifts stay on for?i usually run mine from 10 am to midnight on the weekends and from 4 pm to 9 pm monday thru thursday.i have alot of wear due to high operational hrs as well as weight in the cars,passengers.ill be sending you some pictures of the 16 sheave roller batterys soon. robert

What do you use for the chair grips?

Robert, i use a center rounded groove with 0,75 mm depth. The most "tested" Lift is the "Graffer" which had "collected" about 9000 hours running until yet. Everytime one of the lifts is running day in and day out but the "Graffer" is the one i had used mostly.

@Snoqualmie guy, the clamps based on an electric cable clamp which is used in cable crossings, they had been cutted and grinded to fit the form of the rope wheel groove exactly so both the clamp and the clamp´s screw touch the groove and the board of the wheel. This is neccessary to provide the chairs from sideway movings when passing the sheaves.

Besides that, do you got my private message ?
