Barge Unloading Facility Build

[Rvjimd]

Well, after some testing on the bench, it looks like with my 1/4" wide by 1/4" diameter drum I get about 8" travel from one shoulder to the other. I'm using a heavy thread for cable. If it is simple math/ratio I'm going to need about a 1" wide drum. Hum, need to look at the dock and see if I'm gona like that? Not sure if the leverage on the end is going to be a problem? Would need to mount it in a carrier bracket.

Here are a few pics and a video of the dock side testing of the barge winch system.

Never one to slow down...how about this idea? The belt will drive the secondary drum and should slip enough to account for uneven drum speed due to line stacking. (One direction anyway, might not work going the other way?)



Would need to build a frame to hold both drums, but that should be easy.

(I wonder if I drink too much coffee in the morning?)

Hum.....

I was hoping that the taper on the two belt pulleys would cause the drive belt to shift from one side to the other side when the direction changes. What actually happens is the belt (rubber band) walks to one side and stays there no matter the direction of rotation.

I was going to use this setup to give alternating speed to the cable drums for each direction. That way I could go to two drums instead of one, and the slack issue would be managed by the taper drums.



If it worked, I was going to use a longer shaft on each axel and drive the cable drums from the extensions.
