Sorry if the caption is a bit misleading, but I couldn't think of a better description.

So - here's the query....

I need to make an inclined ramp which is to be powered, that is the vehicle will be chain operated from a winch. What method would you use to power the winch.

I have some ideas but would appreciate any input.

Hi Britho,would this be oo and how would the winch get connected to the truck? I've seen some quarry systems which could be applied to m r but that depends on what purpose this project has.

The winch will be at the top of the incline so presumably there's space underneath to conceal a small electric motor which could drive the winch drum by gears or small rubber band?

Or have the chain running for several turns round the winch drum which turns but is undriven and the chain disappears through a small hole under the winch to the actual drum and motor underneath?

I don't know what sort of vehicle you will be hauling up but may need weighting and wheel/axle treatment to ensure it goes back down again?

Regards,
John

In my previous job I've help construct a pull-system which was a track level conveyor type, it collected a wagon on spikes to carry it to position.

Hi Britho.

How about using a Frizzinghall TT Motor + gearbox ?? That way you could set the gearing to suit your intended rate of climb.

I guess you could use a motor under the board...... a slow one !! and then gear with a worm through a tube, through the baseboard and upto the side of the winch. You could then hide the top worm gear in a tiny box on the winch side and drive the winch that way...... As i have really badly explained it - i will do a drawing later later on and post it up !!!!.................................

Hi Andy

Well, it's 4mm certainly, but the track gauge will be 5', the vehicle will be attached to the winch by a chain. By the way did your restaurant get on to the BBC4 programme that visited Padstow last night?

That could well be the way forward, I will investigate...

I forgot to add that hopefully this will be leading to an "on my workbench" thread, and the whole idea was started last year sometime by Piermaster.

Not sure,I very seldom put tv on,I scan the sky guide couple of times a week but dont usually find anything worthy! Mines a victorian tea room with evening menu so dont get the interest like the posh ones,thank god as we are busy enough anyway.

PS we only have sky as it was cheaper than having a huge aerial fitted,lack of signal down in harbour area.

plastic tube and a bycycle pump works well too

Maplins have a very economical range of 12V 'como' motors with variable ratio gearbox kits, last time I looked the price was under £10. Had one in use for a couple of years on my turntable, excellent performance.

Thanks for that - I'll check it out.

***Hi dave

If it was me I'd use the low geared motor I bet you have somewhere already - a battery drill with a battery thats on the way out or knackered.

I've used these excellent "otherwise waste products" for motorising screen curtains in the full 12" to the foot home theatre, driving a 4mm scale turntable, a mine head frame etc....

These already have a powerful gearbox and DC powered motor combination aligned to a chuck that can hold the driveshaft for the winch - all you need to do is connect it to a trainset controller and reversing switch..... and perhaps a couple of microswitches at top and bottom of travel. Dead easy really - and close to "free" as it can be!

re the drive - if its via belt of any kind, don't even consider anything stretchy - you will get bounce (ever travelled on a cable hauled funicular like in Hong kong and noticed what happens at every stop!!!)

Use a silk or any none-streching material and a weight on a free pulley to keep tension - that way you get drive without the bouncing

Hi Richard

Thanks for some of those ideas - I have a feeling I have a knackered battery drill in the stores.
