Hi David,
It sounds like the common denominator is the pulley, and that's where we would look first. What pulley (or sheave) is being used and is it properly sizes?
We have an enclosed trailer that was modified to haul classic cars. The rear ramp, modified with steel and 3/4 plywood, weighing about 800 lbs., is raised and lowered by a 2500 lb. winch. 5/16 cable runs over a 2" pulley suspended at the ceiling, just inside the door. After only about 20 open/close cycles, at a point EXACTLY 10 inches up from the thimble where cable attaches to the ramp, the "core" stand of the cable begins to protrude about a 1/2 inch. I tried steel, stainless, and galvanized; always happens in the same spot, same time frame! Any ideas why? I've cut 16" off the end, replace thimble and clamps, and it happens again! 5/16" 7x19 Stainless Steel Aircraft Cable - 9000 lbs Breaking Strength
