PSA: A worn swing cable almost cost us a day on the Columbia

We were working a gravel bar near Astoria last fall, pulling steady with the 12-inch suction dredge. About two hours into the shift, I heard a sharp ping and the whole ladder swung hard to port. The main swing cable had frayed down to just a few strands at the fairlead. We shut down right away and I had to splice in a whole new section of cable on the spot, which took us three hours in the wind. It taught me to check those cables with my hands, not just my eyes, every single morning now. What's your routine for checking wear on moving parts before a shift?

You really think a weekly glance is enough? That cable failure wasn't from slow wear, it was from a bad spot at a pulley. A hand check takes two minutes per cable, not fifteen. Lost production is a lot worse when the whole dredge is dead in the water for a half day repair.

That three hour splice job sounds rough, but honestly, a full hand check every morning is overkill. On our dredge out of Longview, we do a visual walk-around with a flashlight at the start of the week and that's it. Cables don't go from fine to a few strands overnight unless something is seriously wrong. Most of the wear happens slow and steady, so a weekly look is enough to catch it. Spending 15 minutes every single day feeling up every cable is just lost production time for us.

You're right about the slow wear, @avery812, but a visual check can miss the broken strands inside a cable that a hand check finds.
