That little scene looks so very real thanks to a few simple things that other layouts seem to miss.

 

Thank you

 

on the subject of small details can you spot the difference

 

 

But don’t phone in, it’s just for fun

 

Clue: it’s only something that would bug me and not a normal person

Is the red cable wrapped around the large pulley a couple of times and physically attached to the large pulley or am I missing something?

 

HELP!!!!

I think your explanation is correct

we have a winner, sorry no prize though

 

I noticed on the photo it was bent so it had to go, still works as a hinge though because I dabbed a spot of glue on the underside of each hinge before cutting out the bit in between 

 

I’m such a fussy so ‘n’ so at times that it even drives me nuts

That’s the only way I could see that working otherwise it would only do a single rotation and be as much use as an ashtray on a motorbike

I was going to say the Birds nest in the Trees, then I realised it was a dirty mark on my screen.

Nice work all around Chris, I'm so envious of your eye for detail. Great stuff.

I had sketched the rope drive in the middle of its travel, with rope wound around each end of the small drum. The rope is secured to the drum at one end, it then goes up over the large wheel and around it twice (for purchase on the wheel) it then runs back down to the small drum and enough rope is wound around the drum, (again secured to the drum at its end) to allow the lifting chain to run all the way out, running the wound rope off one end of the small drum and round the opposite direction to the other end of the drum. The rope drive is then set ready to be run backwards and pull the lifting chain back onto its drum.

I meant it was the only way I could figure out how the one in the photo works, what you suggested makes perfect sense

I see, sorry, thought that I had drawn it looking as though it was locked solid.

You’re quite right and thank you for the suggestion of adding the road sign

Sorry about this guys but I'm still trying to get my head around the hoist cabling

 

I found this photo that appears to be rigged up

 

 

The chain (in green) goes over pully 'A' to drum 'B' which in turn is connected to the large pulley 'C'

 

However there only appears to be a single cable (in red) from pulley 'C' to the winch 'D'

 

Is the red cable wrapped around the large pulley a couple of times and physically attached to the large pulley or am I missing something?

 

HELP!!!!

 

This is how I thought it was done

 

 

 

So now I'm totally confused

 

 

 

As others have said, there were several ways to skin that particular rabbit. For this example, if it's the one you intend modelling, I think your first suggestion was correct, there being only a single rope running from the lower cranked winch to the large wheel at the top, with no second rope visible, at least to me. There appears to be a brake lever to control the lower winch, and, in any case, gravity will be providing considerable assistance in the lowering process, not requiring any manual effort. I would be worried if the system depended on the friction in the upper pulley, as there could be several reasons why it might fail to grip.

I've found a similar example in "Operating the Caledonian Railway Volume 2" taken at Lesmahagow which seems to show this single rope arrangement with at least five coils of rope wound around the upper pulley, as this snip shows, albeit a bit on the dark side.

Me too, and so too other modern sources (like the usually excellent https://igg.org.uk/rail/9-loads/11-crane.htm, as below):

 

 

Now, not to say we're wrong, prototype for everything etc etc etc...but...

 

 

 

Mr Appleby, at least, did things differently.

 

The good news, is this makes sense of the Bakewell cranes you were previously working off. Here's the reciprocal view, from which

 

and of another image, at Fishergate Hill Station, in 1927, from which

Note also that the wheel is empty between the rims [EDIT:] with the hook chock-a at the jib head (follow link to full image).

 

Had I checked the Appleby before marking the photos, I could have skipped the question mark!

 

I was looking for myself, because I didn't know the answer, but perhaps you'll find it useful. As ever, it's offered to try to help you make decisions you are happy with on a project it's a perpetual pleasure to follow. One reason for that is the effort you put in to make Warren convincing, and one aspect of that is the accuracy you strive for. How big an arse would a person have to be to withold information which could support that aim...?

 

All the best,

 

Schooner

 

ps. For completeness' sake, the only reference I can see for a cross over of the drive rope is the previously posted render, from here. The model is based on the yard crane at Dunster:

...which gives little away. I can't find anything on how the crane was set up in its working days, although it must be out there somewhere...

Thats brilliant! Extremely helpful. Thank you very much

 

This is what I was going for...

 

 

What size timbers do you think they would be? I’m thinking the main upright is about  8” or 9” square maybe?

[Schooner]

That neck of the woods, maybe a shade more. If it helps for mine (assuming nothing off the peg will quite work) I'm planning to use .135" (3.4mm) styrene strip which equates to a bit over 10" in the real world.

 

Some other numbers from the same source:

• 12' jib radius
• 10' height of lift
• handle 2'10"-3'0" above the platform
•  the crank handle would be 14-16"

 

By the way, the yard entrance looks excellent. Truly

The maximum Jib radius I can achieve is about 8ft (to allow 360 degree movement) but otherwise that info is very useful, thank you

Thank you, I’ve actually surprised myself how well it’s turned out

Having said that this one looks like it would struggle to be fully rotated, unless it’s an optical confusion

 

So maybe it’s not that important?

Does have to do 360 getting to far side of wagon to me seems more important?

I agree, I would imagine as long as goods could be lifted and rotated far enough to put it on the platform that would be sufficient?

Anyway not all goods sheds used cranes, some used ivy
