I think FlyingBeagle (sorry don't know your real name) was talking about this video:

Hope this helps.

Jim,
what about an overhead gantry crane that travels in the two horizontal dimensions, with a grab bucket. That way you can push the barges under the gantry with the tug and then unload. The gantry cranes where I worked at a cement works in NSW Australia took the material to the stock pile. They could simultaneously supply material to the raw mill hopper feed. You could do the same but instead of the hopper feeding a mill it could feed the conveyor to your silo with underneath rail loader. Just my 2 cents worth of ideas. Really like you modelling work and the pond is fantastic. Well done.

Ya, I'm sort of leaning toward some form of gantry crane. I think I'll keep it stationary and the trolley will go out over the barge and back to the conveyor or stock pile. And, the clam grab will go up and down.

I wish I could draw better, I would love to show some sketches and get more feedback. It would also be nice to see some of it on paper first before I start building.

Just two pictures of the start of the barge winch system. This will be the winch mounted on the dock. I plan to string a cable (string) continuous around the drum to a pulley at each end of the dock. I plan to install 2-4 shackles on the barge side of the line that can be hooked to the barges easily. This particular drum is made using two parts of brass tube and two fender washers.





Going to hook this one up using two push button switches and use a couple nimh or nicad cells to run it.

I'm hoping I can install a spring so e where on the line and friction on the drum with about one wrap, have to see if that works out.

Man my brain has stopped working...

Here is about the fifth drawing I have made but none of them look like they will work. In this one, I think the battery will short out when a push button is pressed.

The switches are norm open. There should be a way to do this with two push button switches correct?



I want the servo to turn CW or CCW depending on which button is pushed.
