Hi, I need help by explanation of how a double drum winch is strung with cable.
This is for my ACUTR build.
The two larger pictures below are of left and right side of the winch that I'm trying to build.
The three thumbnail pictures below that are samples of how I think it works but I don't know.





If you click on the thumbnails of these samples, and pick the one that works if you know. Or if you know the real way it works if none of my samples are even accurate.

The first image is of one cable strung between them but working together going up over a pulley, then out to boom.

The second image is the cable being stung multiple times between them, working together.

The third is of them working completely independent of each other.



Thanks you!

Gee thanks Ko, I'll be thinking on this all day at work l.o.l.
In your first pic. the drum on the right is the geared drive wheel, in your three pics. on the bottom the first or third looks good, but I'll have to check some bucket/cable trucks at work to see if anything looks similar.
Later - Cheyenne

Thanks for the replies, fellas.

cheyenne, I didn't mean to burn you out on this, LOL, but if you have insight on these systems, I would be very interested in this information.

hey, MATT, I found this sight during my pre thread post research and it looked like one cable between them working together... but still not sure, pics are small. Thanks you for the link.

Also, this vehicle is old, '30s maybe. And this double drums are at the base of a crane boom. And this is not a riddle, I really don't know

Dam, Ko, checked every truck in the yard and I was told the double winch rig was out to Deleware !!!, figures !!!
I did ask some questions about it but even he said you really have to see it while its function is being explained to understand it.
More later after the weekend when I go back to work and the cable truck with the rig on it is back in the yard.

Hey that's cool. Thanks for the foot work on that so far.
I received a few PMs regarding this as well, and I going with the independant third picture direction as you have also suggested. The deadline is approaching and I have to finish this one.
I you get more information this weekend about this thing, please post here. Plastic assemblies can always be changed...

Hi KoSprueOne

All winches that I have used work independent of one another. I have used cranes with multy winches to lilft and then tilt the load vertical at the same time.

regards,
Ralph

Thanks Mech,
This has been the most solution replies I have received.
One cable attached to the load and the other cable controls the elevation of the boom.
It all makes sense now.

Thank you everyone.
