Barge Unloading Facility Build

[FlyingBeagle]

What if the cable didnt have to wrap all the way around the drum. It should not take much force at all to move the barges. If you built it like a basic rope tow at a ski resort you wouldnt have the problem with the calbe walking on the drum. Put a large traction wheel on the motor with smaller pullys below it on both sides. The cable is fed in below the small pulley, around the traction wheel and back out under the other small pulley. You could even spring load the pulleys to maintain tension.

Kind of like the block used to pull up the pots on deadliest catch.

Here is another homemade version of a ski tow that shows the principle I am talking about.
